Tradition, Technology and Experience


Dr. Carr and his staff are the best. I always looked forward to going to my appointments because it felt like I was going to see friends. They are all very thorough and precise when doing their jobs. They make sure to explain everything they are doing and they will always answer your questions if you have any. I would highly recommend Dr. Carr! - Sarah H.
When I moved to Indiana I had visited several orthodontists in my original home state and for some reason just didn't feelmok with their plans of treatment. 5 minutes in Dr. Carr’s office and I was so comfortable with the staff and him. The 3d x-rays showed so much stuff I didn’t know it was amazing I started my treatment 3 weeks ago and I can't say enough about the amazing staff and Dr. Carr himself. - Jessica S.
Absolutely love Dr. Carr and all of his staff! He is thorough, friendly, and always on time. The same can be said about all his lovely staff. My oldest son had braces and we were so pleased with his teeth and our experience with Dr. Carr that I decided to do Invisalign through him. One year later and my teeth look beautiful. One more son to get through braces and, of course, we will be back with Dr. Carr! - Beth H.
Dr. Carr is Amazing! Attentive and knowledgeable! I would Recommend Dr. Carr over any other Orthodontist in Lafayette. The staff are wonderful as well, they make you feel super comfortable and give you compliments on the small changes. Overall 10/10. - Stephanie B.
Our daughter used the SureSmile technique, and was done in 14 months instead of an estimated 2 years! We are impressed with the beautiful results. Even though she was an apprehensive patient, Dr. Carr and his staff were gentle, calm, and professional with her. By the end of the treatment, she no longer nervous about upcoming appointments. - Sarah W.

Timing is everything – even when it comes to your child’s orthodontic treatment. “Early” treatment, also called “interceptive” treatment, means treatment that is performed while some baby teeth are still present.

The American Association of Orthodontists (AAO) recommends that your child’s first check-up with an orthodontist be performed when an orthodontic problem is first recognized, but no later than age 7. Why age 7? By then, your child has enough permanent teeth for an orthodontist to evaluate the developing teeth and the jaws, which in turn can provide a wealth of information. Dr. Guthrie Carr is trained to spot subtle problems even in young children. You may view photos of such problems here: Problems to Watch for in Growing Children.

There are generally three outcomes of an initial check-up:
  • No treatment is expected to be necessary.
  • Treatment may be needed in the future, so the child will be followed periodically while the face and jaws continue to grow.
  • There is a problem that lends itself to early treatment.

While there are many orthodontic problems that orthodontists agree are best treated after all permanent teeth have come in, early treatment can be in a patient’s best interests if their problem is one that could become more serious over time if left untreated. The goal of early treatment is to intercept the developing problem, eliminate the cause, guide the growth of facial and jaw bones, and provide adequate space for incoming permanent teeth. A patient may require a second course of treatment after all permanent teeth have come in to move those teeth into their best positions.

The kinds of problems orthodontists may recommend treating while a child still has some baby teeth include:
  • Narrow dental arches with airway restrictions
  • Underbites – when the lower front teeth are ahead of the upper front teeth
  • Crossbites – when the jaw shifts to one side
  • Very crowded teeth
  • Excessively spaced teeth
  • Extra or missing teeth
  • Teeth that meet abnormally, or don’t meet at all
  • Thumb-, finger-, or pacifier- sucking that is affecting the teeth or jaw growth

Some of these orthodontic problems are inherited, while others may result from accidents, dental disease, or abnormal swallowing.

Early orthodontic treatment can take many forms. The orthodontist could prescribe a fixed or removable “appliance” – a device used to move teeth, change the position of the jaw, or hold teeth in place in order to bring about desirable changes. Sometimes no appliances are necessary. Rather, removal of some baby teeth may help the permanent teeth erupt better. The extractions will be timed to take best advantage of a patient’s growth and development.

Regardless of how treatment goals are reached, the bottom line is that some orthodontic problems may be easier to correct if they are found and treated early. Waiting until all the permanent teeth have come in, or until facial growth is nearly complete, may make correction of some problems more difficult.

Dr. Guthrie Carr offers complimentary evaluations, No referral needed!

Now a word about the overuse of early treatment: Caveat Emptor Parents need to be aware than some orthodontic offices make it a practice for almost every patient to receive early orthodontic treatment. They often characterize this a “special kind of treatment”. They are “the only ones who can help you with this special treatment”. The most common example would be the over use of early expansion.

Early expansion is important for airway problems in young children, cross bites and severe crowding. It is probably not needed for mild to moderate crowding when the bite is correct. If you visit an office where every young patient “needs 7 millimeters of expansion”, or they threaten you that they will have to pull 4 permanent teeth in the future if you do not do this now, get a second opinion!

Also, another unfortunate occurrence is to over charge for the first phase of early treatment with a promise of a credit at the second phase. Early treatment should be less than half the cost of current full treatment. If you pay more than this at the start, you have already prepaid for the second phase and the office is holding your money. What if you move, or do not need a second phase, or want to go to another office after the first phase? The fee should be proportional to the treatment provided at the time it is delivered and not come with a future promise tied to a second phase of treatment.

If you had braces, but stopped your retainers and watched your teeth move, we can help you.

If you thought you did not need orthodontics, but now your teeth are not aligned, we can help you.

With up to 14 aligners over less than 6 months, we can make the changes you are seeking and restore your confidence in your smile.

Unlike mail order aligners, this treatment is orthodontist designed and supervised. Our treatment includes office visits and a second scan to improve your results from the first set of aligners with a second set of aligners.

When you finish, we will provide you with 4 sets of vivera retainers to make sure you won’t have those unwanted changes again.

Dr Guthrie Carr is greater Lafayette’s only Platinum level orthodontist certified by Invisalign.

SureSmile® Braces are Next level 3D orthodontic treatment

SureSmile orthodontic treatment takes the idea of custom orthodontic treatment to the next level with computer generated imagery and robotically-molded archwires. This technology represents the most precise treatment available today.

What are SureSmile Braces?

SureSmile is a cutting-edge 3D digital imaging and computer-aided prescription program that allows your orthodontist an unprecedented level of treatment accuracy and precision when deciding on your alignment and braces.

How does it Work?

Using both an Itero impression free scanner and your 3D radiograph, a dynamic 3D model of your teeth and bite is created, which gives your doctor a complete picture of how your teeth are aligned and how they fit together. This dynamic model is then used in conjunction with the SureSmile Treatment Planning software. This virtual simulation allows your doctor to interactively create the most effective treatment plan possible that suits your unique prescription. He can see your teeth, roots and bone as well as integrate your smile photo into the plan to design your smile. Additionally, your customized archwire is custom bent by a SureSmile robot, rather than being shaped by a doctor. The robot can heat the memory alloy in the archwire to shape the wire in first, second and third order movements and provide accuracy to 0.1mm—something regular orthodontists cannot do by hand.

What are the Benefits of SureSmile?

One of the major plusses is the accuracy with which your doctor can predict and plan for tooth movements. This anticipation and smoother movement results in faster treatment times (some sources have suggested that it can be up to 40% quicker). The quicker your braces come off, the quicker you have your perfect smile and return to your normal dental hygiene habits. This maximum control offered by the robotically-shaped, heat-molded alloy archwire also means that teeth are moved in the most direct path so that you can expect to spend less time in your orthodontist’s chair for adjustments. Fewer adjustments also means less discomfort over the course of the treatment.

Lastly, your smile will look fantastic thanks to the benefits of smile design!

Invisalign has become a popular option for many adults and teens today for many reasons. Invisalign may fit your lifestyle better than traditional braces. If you are involved in music, sports (teens) or public speaking (adults) this option may appeal to you.

Treatment is planned out in advance by the orthodontist allowing a smoother treatment experience with fewer appointments now often 10 or more weeks apart and often with shorter total treatment time. Digital 3D scans now replace old fashioned impressions to capture your bite. This removes a common source of anxiety among patients.

Questions to ask when choosing an Invisalign provider:

Are they an orthodontist? Orthodontists are dentists with 2 or more additional years of university training. There is a reason for the specialty. Trust your smile to a specialist for the best results. Your orthodontist will work with your dentist to coordinate your treatment.

What is their experience? If your dentist or orthodontist “dabbles” in Invisalign, you may not get the most from your treatment. Check the provider's tier level on the find an Invisalign provider page. Bronze, silver and Gold level providers submit these cases with a lower frequency than Platinum level providers and above. There are a lot of nuances to this treatment protocol (they are not just clear braces), your provider's experience is an important part of your experience.

Do they use the iTero element 2 scanner? This digital scanner allows your orthodontist to submit your scan digitally. It is more accurate than impressions and faster. Beyond the initial scan, this scanner allows us to do 3D simulations at your initial consultation to help you see what your smile might look like after treatment. This scanner also allows future comparisons to your plan for progress assessments and it also will show us your occlusion (bite) for a better assessment. Knowledge is power and this scanner is the gateway to knowledge regarding your case.

Do they include refinements in the treatment plan and cost? Refinements are when the first course of aligners are completed, a new scan is taken and resubmitted for additional treatment planning and aligners. You rarely get 100% of the first Invisalign plan and this step is a critical quality control step. This is the opportunity to go from better to great! It is also the time for the patient to offer their input into their treatment progress. Many offices do not offer refinements or they charge additional for this service.

Dr. Guthrie Carr is greater Lafayette’s and the Purdue area’s only Platinum level orthodontist offering Invisalign. Dr. Carr uses the iTero element 2 scanner to offer his patients the best experience including refinements in your case.

Getting the smile you’ve been wanting has never been easier! If you are considering orthodontic treatment for you or your children give our office a call to schedule your complimentary evaluation.

Invisalign teen is now a great option for many active teens.


For the past two years I have been quietly treating teens with Invisalign whose parents request it. 

Why do the parents ask for Invisalign teen?  Invisalign Teen is a unique treatment course that will allow dedicated patients to have shorter treatment with fewer visits than those patients with braces (Don’t get me wrong I still love the precision of Suresmile in my practice and it affords me the greatest amount of control in treatment).

Invisalign Teen is well suited for teens who are focused and dedicated to their school work, sports and music.  Invisalign teen will often allow me to have a greater length between appointments and thus fewer appointments.

What are the drawbacks?  Well compliance is an issue.  If your Teen constantly has to be reminded to do things and procrastinates then braces with the precision of Suresmile may be our best route to success.

I was recently invited by Invisalign to participate in the Invisalign Teen Summit in California based on the amount of teen cases I am treating.  What we found was that overall teens are as good as or better than adults in the aligner compliance department.  That follows my experience.  In the past two years I have had to convert two adults to braces, but only one teen for poor compliance.

If you would like to consider Invisalign Teen for your child, give our office a call to schedule a complimentary evaluation.  Our impression free scanner will allow us to capture a digital image of their bite and do a simulation to show you what we can do to improve their smile.

Recently I was challenged by a patient: “my dentist has an Invisalign sign at their front desk and the staff say their dentist can do this for me too?”

What are the differences between orthodontist driven Invisalign and general dentist driven Invisalign?

First of all the keys to successful treatment are: patient compliance, the proper plans and proper biomechanics. Notice I said plans! Many dentists are accustom to preparing a crown and then taking an impression and sending it off to the lab to be made by a technician. To that end, Invisalign appeals to them; take an impression, send it off to the lab and get back a kit to move the teeth. Simple right? Well maybe not so fast.

Let’s consider the differences in the process and why they are important to you.

The dentist takes and impression and sends it off to the lab; most orthodontists will not take an impression, but rather obtain a 3D digital scan. This is considered more accurate as it can be refined during the scan to improve the quality (it is also sent in electronically speeding the process) with an impression you get one chance, if there is a bubble or an error, you repeat the impression until all of the teeth are perfect. This does not usually happen so the impression gets sent in to the lab with minor errors, this can affect the fit and performance of the aligners.

If your dentist is going to take a traditional impression, that is an indication that they dabble in Invisalign and do not do it on a regular basis. Another way to check your dentist is to use the find an Invisalign provider web page. If your dentist is not listed, then they do not use the product often enough to be listed as a provider.

Every provider submits a prescription to the lab. The details in the prescription are important in getting a good plan. I do not recall the last time I accepted Invisalign’s first proposal. I will generally modify the plan or four times before I accept it. How many times does the dentist modify the plan? My guess is most dentists accept it as is. Why, well reviewing the plan is a complex process that requires time and knowledge of how teeth move. The plan is an animation, and just because it looks nice, does not mean it will work. Over expansion, too much tooth reduction, teeth moving in ways that cannot occur in the mouth…

It is critical for the orthodontist not only to determine if the plan is appropriate, but achievable. Regularly, the first proposal from Invisalign will not work in my opinion and requires additional changes. What does that say for plans for patients where the initial plan is accepted from the company without changes?

Revisions: most orthodontists know that after the first round of aligners, an additional plan for refinement aligners is necessary. Again, this is where the 3D intraoral scan is helpful. A new scan is obtained and within a few weeks a new plan and new aligners are available to move forward from the initial results. This is common in orthodontics where the orthodontist evaluates what they wanted from their treatment mechanics and what they got and now what is required to move forward toward the goal. The key, as always is understanding the plan and making sure it is realistic (the animation/plan will show anything is possible, it it’s the provider that must determine if it is realistic).

Additional technology: I have a 3D dental radiography machine that gives me a 3D x-ray. This is important to determine when and how much expansion is permitted. If you exceed this amount the teeth will be pushed out of the bone causing relapse and an unhealthy situation.

In summary I would say that while your dentist can take an impression and get back trays from Invisalign, your experience and thus results will be different from the orthodontist driven treatment.

I know you market your practice with the tagline “Tradition, Technology and Experience’. Tell me about that?
Well the tradition portion refers to my families’ heritage as dentists in Greater Lafayette. We have over 100 years of continuous practice! If your family is from greater Lafayette, there is a good chance that I, my father, my uncle or my grandfather has treated someone in your family I take that tradition very seriously in our relationships with our patients. We value the trust the community has placed in our family over the past 100 years. Technology refers to the changes that are available to let orthodontist improve the patient experience. Not every orthodontic practice embraces new technology.
Why is that?
Technology can be very expensive, it can disrupt the rhythm of office workflows and it takes time to learn and master. I have invested in newer technologies that provide better information for diagnosis and treatment. This allows for shorter more comfortable treatment and improved results.
Tell about these technologies?
Firstly, our ultra-low dose ICAT 3D scanner is amazing. It allows me to get a 3D scan of a patient with less exposure than a digital panorex which is the most common orthodontic X-ray. It is not uncommon for me to find information that was not seen on a previous traditional X-ray. I can sublimit this ultra-low dose scan to a third party who will turn it into a dynamic model. This is useful in pretreatment simulations for early treatment expansion, surgery cases, cases that might need restorations or implants when the orthodontic part of the treatment is finished. It is a great learning tool for me and a great communication tool for the patient and their dentist. We also offer digital video scanning that replaces traditional impressions. This allows us to send information digitally to labs we work with like Invisalign and Suresmile.
You offer Invisalign? Tell me about that?
When Invisalign first was introduced, I did not offer it because I did not think the product could deliver on expectations, recently Invisalign has made a lot progress in their implementation of new technologies. I am now confident that Invisalign is a great choice for a variety of problems. I have spent a lot of time in continuing education learning the nuances of their technology and how to best apply it for each individual case.
What is Suresmile?
Suresmile is a fantastic technology that allows me to use the 3D scans we take and create a dynamic model of my patients. I can see their teeth, roots, bone, and the braces. I can even link their model to their smile photo. This allows me to simulate the desired final result with more information than is available in conventional orthodontic treatment. From this plan I prescribe custom wires that are bent robotically for to maximize their accuracy. These custom wires allow me to make the simulations come true. After I simulate the final result I can design the final smile using the photo linked to the model. This is very powerful because often the smile is why our patients come to us, the bite and the function is what orthodontists are focused on. With Suresmile I can optimize both. Oh yeah, it also shortens treatment. Patients love that.
What about the experience?
As an orthodontic specialist I have two years of additional education beyond dental school focused solely orthodontic diagnosis and treatment. I have been in practice for over 25 years. I am actively involved in my professional societies and meetings to learn both the science and the technologies that effect our diagnosis and treatment planning.
What else would you tell someone about your orthodontic practice?

I have a wonderful staff who are fun and talented and really engaged with our patients and their families in the office. They really make the office environment a great place. We love our patients and I think our patients would say it shows.

Does your child have trouble in school? Do they snore?

Many bright children experiencing behavioral problems and difficulty in school may have sleep disorders caused by airway issues. Only a sleep doctor can diagnose problems such as pediatric sleep apnea, but when the airway on a child is small it can result in sleep apnea and poor sleep. The airway size can often be improved with expansion of the dental arches allowing the tongue to posture forward and open the airway in the pharynx and improve sleep.

Dr. Carr’s ultra low dose 3D scanner will allow him to visualize many hidden problems including an airway analysis in just seconds. Combining this technology with Dr. Carr’s 25 years of experience you will know if your child needs early intervention or can wait until adolescence for a single treatment with braces.

The American Association of Orthodontists recommends that every child have their first orthodontic exam by age 7. Our ultra low dose 3D scanner allows us to do an airway analysis for your child  in conjunction with our examination.
