What is ‘Shaving Teeth?’
Patients usually ask about the process of “shaving” or “filing” teeth as a way to make space for straightening. The name of this procedure is “Interpxoimal Reduction,” (aka IPR) because it involves reducing the enamel width in the area between the teeth. It is usually prescribed on patients with over-crowding, where space is needed for tooth alignment. IPR is used as an alternative to removing permanent teeth. The amount of enamel removed depends on each specific case. Your orthodontist, a dental specialist, will prescribe the specific amount of enamel removal based on your case.
Our patients also ask what instruments are used for IPR. That’s a fantastic question as different doctors use different instruments. One of the most common is a very thin diamond strip – a precise, thin, flexible piece of metal that fits between teeth. The orthodontist will slide it back and forth to grind away the enamel. Another common instrument is a diamond disk, which looks like a round diamond-coated circle that is used with a dental handpiece. IPR can be performed with both of these instruments in a very short period of time, and there is often little to no pain involved.

FAQ:
Is it bad to shave teeth for Invisalign?
Does interproximal reduction (aka shaving teeth) hurt the teeth?
Research has shown that interproximal reduction is an extremely safe procedure. Over the long term, there is no increased risk of cavities or periodontal disease. In some cases, IPR can decrease the risk of periodontal disease because teeth that are straight are easier to keep clean over the long term. One technique that many orthodontists use after IPR is to place a fluoride-based gel over the enamel surfaces. This is helpful to remineralize the enamel.
How much enamel is removed?
Thanks to new advances in digital technology, the orthodontist is able to predict, with a high level of accuracy, exactly how much enamel should be removed with IPR. Many orthodontists use computer models, especially during orthodontic treatment with clear aligners, like Invisalign. Based on the computer model, the orthodontist will prescribe the exact amount of IPR that is needed to achieve ideal tooth alignment and position. Depending on each case, the average amount of enamel that’s removed is between 0.2 and 0.5mm per contact…so less than one-quarter of a millimetre per side of each tooth!
Are there any alternatives to filing down teeth during Invisalign treatment?
- During your Invisalign treatment, you can create spaces in several ways:
- IPR (file)
- You can shift your back teeth outward during the treatment.
- Proclination (shifting your front teeth out) is another option.
- Distalization (moving your back teeth backwards.
