Toothbrush abrasion is a wearing down of the enamel (the outer layer of the tooth) and sometimes the subsequent recession of the gum tissue in the same area. Toothbrush abrasion typically occurs on the outer surfaces of the teeth that are easier to access with the toothbrush but can occur anywhere in the mouth. Toothbrush abrasion can be localized to a single tooth or generalized to several teeth.
