What Is IPR?

March 24, 2023

IPR stands for interproximal reduction. Interproximal reduction is a technique that has been used for decades in dentistry, most commonly in orthodontics, to create more space for tooth movement and help teeth fit together more appropriately for a beautiful smile [1].

During an interproximal reduction procedure, your oral healthcare professional will remove a small amount of tooth enamel on the sides of your teeth to help reshape them.

Interproximal reduction can be used for both braces and clear aligners, and even in cosmetic dentistry. So when exactly is IPR used, and why is it necessary? Learn more about the methodology behind IPR and its applications below.

Create More Space and Stability

Interproximal reduction is most commonly used for treating crowded teeth in orthodontics. Instead of removing permanent teeth, IPR can increase the amount of space between teeth as well as space between the upper and lower rows of teeth to correct improper bites [2]. IPR can even help orthodontists properly close gaps with braces or clear aligners by reshaping the teeth before moving them together.

However, IPR isn’t just about creating or reducing space. It can also improve the outcome of orthodontics by reducing teeth shifting after your treatment is complete, creating more stability in your new smile [3].

Improve the Shape of Teeth

If you have gaps or odd spaces gum tissue does not fill between teeth, IPR can help reshape the teeth to fill gaps that may leave your smile looking less than ideal.

IPR is mostly done on the outsides of the teeth, or where two teeth come together, to help position them against each other properly. By reshaping the structure of the teeth on these sides, your orthodontist is better able to fit the teeth together for a uniform smile. The result will be a seamless and beautiful smile once your treatment is complete.

Can a Dentist Perform IPR?

A dentist can perform IPR for certain cosmetic treatments, such as for reshaping teeth and to help close gaps with dental bonding as opposed to using crowns or veneers [4]. So orthodontists aren’t the only ones that can use this technique to help improve your smile!

What to Expect With IPR

If you are a candidate for interproximal reduction, you can expect the procedure to be relatively quick and not painful. During an IPR procedure, local anesthesia is usually not needed. Your orthodontist or dentist will use a small tool to remove a tiny amount of tooth enamel from the sides of your teeth. The process takes just a few minutes to complete, but can have a dramatic effect on your new smile.

IPR may even make it easier to clean your smile once your treatment is complete, as you won’t have awkward gaps where food can get stuck or plaque can build up and cause tooth decay, gum disease, or bad breath.

Ask Your Orthodontist or Dentist About IPR

If you’re concerned about the way your teeth will fit together after orthodontic treatment, or just want to reshape your teeth for a more uniform smile, ask your oral healthcare professional if you are a candidate for interproximal reduction. IPR is a minimally invasive procedure that can have a big impact on the appearance and function of your teeth.
