Is It Normal to Have Some Mouth Sores when You Begin to Use Invisalign?

Are there any over-the-counter medications available to help with this?

Mouth sores because of Invisalign

Sometimes wearing the aligners, specially at first. The constant rubbing with the lips, tongue or cheeks can give you sores. It is completely normal, as you wear your aligners, your mouth will adapt to something new in the mouth, give it some time. We always recommend our patiemts to do warm salt water rinse, it helps to heal faster and for the sores to go away quickly. Don't give up , always remember you are doing something extraordinary for your overall oral health!!

Mouth sores with invisalign

During the beginning of invisalign it is very common to have your lips and cheeks irritated but the edges of the trays.  Once your mouth gets used to them this should no longer be an issue.  You can use canker sore medication.

Edges of Invisalign trays can irritate tissues

It is not unusual to have lips and cheeks irritated by the edges of the trays from Invisalign at first.  Over time, the tissues will adapt and you will hardly notice.  In the meantime, canker sore type medication can help, as it makes the tissues a little numb.

Mouth sores are common in the initial part of orthodontics.  It is rarer with invisalign.  It could be some rubbing.  Or it could be a coincidence.  If it doesn't get better in a week or so go see your dentist.

Good luck with your treatment

It is possible to get small sores

It is possible to get small sores when you are first adapting to the tray. Most of the time it is due to a rough edge on the aligner. This can be avoided by simply smoothing these edges with a nail file.
