A canker sore or some type of an ulceration would feel sore to the touch, acidic foods may bother it and it can become inflamed and very red. It would not hurt to rinse with warm salt water a few times a day for a few days and see if that helps. These types of sores can last from 7-21 days. Usually they are the most uncomfortable for the first week and then slowly taper off.

If the area becomes more swollen ... you develop a fever or other sign of possible infection... or the tooth starts to hurt, then see your dentist sooner than December.

Hope this is helpful to you. Keep us posted.
