I have a canker sore on the inside of my bottom lip. it's been there for a week and it keeps getting bigger. it now has a thick white stuff on it. what should i do?

See a dentist: Canker sores usually last about 2 weeks. I put zilactin on the canker sore and it helps it to heal up and most importantly, it reduces the discomfort associated with them. You can purchase this in a drug store and is over the counter. If it lasts longer than 2 weeks, see a dentist.

Patience: The white stuff is your skin trying to heal over the sore. It usually takes anywhere from 10-14 days for a sore in the mouth to heal. You can cover it with orabase, use anbesol or another oral anesthetic to ease the pain, or have your dentist use a soft tissue laser on it.

Call your dentist: Cankor sores take 10-14 days to heal so topical creams at the drug store work best until the body heals.
