I have a bad habit of biting my cheeks. this has made them sore & cut inside. as well as warm salt water, what else can i use to help heal them?.

Hydrogen peroxide: You can rinse your mouth out with hydrogen peroxide which will help the healing process.

Parafunctional habit: Best thing to do is eliminate the cause of your traumatic injuries. If you cannot do that on your own you may need professional support. Your Dentist can make a protective mouth guard for you to wear to protect your cheeks. Rinse and spit out 1 tsp salt in 8 oz warm water 3x/day. Take NSAIDs as per package directions to reduce need to chew. Apply Orabase-B with Q tip.
