Stan,

This is a very annoying problem. Since you have had periodontal work, it seems that the periodontist should be required to fix this problem. I am inclined to think the ceramic teeth are not aligned properly and you are suffering from misalignment (malocclusion) and it has little to do with them not being natural teeth.

One other problem (as you point out) is that when tissue is damaged from biting the inside of the cheek or the lips, we are likely to bite this area again because of the swelling whether one has implants or natural teeth. Treat the wound immediately:

1. Apply ice packs for the first 3 days. …
2. Rinse with salt water two times a day for 3 days.
3 Take an over-the-counter pain reliever.
4. Apply topical numbing ointments available over-the-counter at any pharmacy.

How long have you had these implants?

Not a dentist or health care provider, just an interested person, seek the advice of your physician.
