Before you start your journey with Invisalign, you may need an interproximal reduction. It’s something that many people need to undergo before they get orthodontics, but what does it do? You might’ve heard it helps you have a successful realignment of your teeth and bite, so here’s more about this procedure to ensure you know how it can benefit your smile.

What is an Interproximal Reduction?

Interproximal reduction, or IPR, is used to slightly modify the shape of certain teeth, particularly in preparation for orthodontic treatments such as clear aligners. This minor change helps create more space between your dental structures so any crowding can be more effectively corrected. That way, your bite pattern can then be improved.

There are a few ways that this technique is done, but they all only remove a tiny amount of enamel. In fact, what they take off or alter is thinner than the thickness of your fingernail! It won’t be an overly obvious change, but you may have some sensitivity afterward.

Why Do I Need an Interproximal Reduction?

With that said, you might wonder why you need an interproximal reduction in the first place. Simply put, it’s mainly used when there isn’t enough room in the jaw for all of the teeth to shift into their desired positions. It’s used to address orthodontic concerns, such as:

  • Crowded Teeth: A grin that’s tightly packed or has overlapping can be trouble for Invisalign, so creating a bit of room can make it easier for your trays to work as they are meant to.
  • Bite Problems: Getting an IPR can help with the precise fit of your teeth, essentially improving the function of your smile while potentially making it more comfortable.
  • Gaps Between Teeth: If there are small, triangle-shaped gaps, then an interproximal reduction can help reshape contact points to close them.

Will I Need an Interproximal Reduction?

In most cases, getting an IPR is often preferable to create space rather than getting a tooth removed. While the latter is needed in some cases for certain patients, your dentist is here to help you get started with orthodontics. They will do their best to ensure you have a smooth process and get adjusted to your clear aligners. That way, you have an easy transition and take a step toward the straighter smile you want.
