Abfraction - Loss of tooth surface near the gum line, or at the cervical areas of the teeth, which is caused by compressive and tensile forces during tooth flexure. This is enamel loss in wedge-shaped notches, which are susceptible to decay and can become very sensitive because of dentin exposure. Depending on the extent of the loss of tooth surface, treatment may or may not be required.

Tooth-colored bonding will fix tooth abrasions.
Abscess - an infected area of the gum which is an accumulation of puss in a localized area of the gum. It is caused by tooth decay that infects the pulpal tissue which is located inside the tooth.
