If I grind my teeth will it ruin my Invisalign aligners?

Great news for those who grind their teeth; Invisalign aligners can help protect your teeth and actually help with the causes and symptoms of teeth grinding!


It's fair to say that most people are likely to grind and clench their teeth from time to time, especially while sleeping. 

While occasional teeth grinding, or bruxism, does not usually cause notable harm, frequently grinding your teeth can lead to your teeth becoming worn, chipped or cracked.

Regularly grinding your teeth could also make you more vulnerable to TMD (temporomandibular disorder). 

Teeth Grinding & Invisalign

If you grind your teeth and you're considering Invisalign as an orthodontic treatment option there is good news. Invisalign clear aligners actually create a cushion between your teeth, much like a night or bite guard would.

Wearing your aligners for the prescribed 20 - 22 hours a day (including during sleep) will help to protect your teeth from the affects of grinding while you're wearing them.  

Addressing The Root Cause

Invisalign orthodontic treatment could also help address the underlying causes of your teeth grinding, depending on your reasons for choosing the clear aligners. 

While Invisalign is adjusting your bite, it could also help to deprogram the mouth and jaw muscles used when grinding your teeth. 

Adding a Night Guard to Your Treatment Plan

Even with Invisalign aligners in place, some patients do continue to grind during their treatment. Persistent grinding can cause premature wear on the aligners, but this can be easily addressed.

If you find that you continue to grind your teeth even while wearing your aligners, your dentist may recommend that you're fitted for a night or bite guard. A properly fitted guard will give your teeth and aligners an extra layer of protection.
