Abrasion Defect is caused by mechanical trauma to the tooth around the gumline due to abrasive action of toothbrush. Usually there is also recession of the gingiva (or gum). The gingiva receded because there might be underlying periodontal disease or due to repeated mechanical trauma of the toothbrush. Once the gingiva is receded, the root surface area will be exposed. The root surface area is more prone to mechanical abrasion because biologically there is no enamel to protect the root area. Overtime, with repeated tootbbrush abrasion, the neck of the tooth will be abraded and a notch will form.
There are multiple ways to resolve the problem. One way to undergo tissue grafting of the gingiva to repair the receded gingiva tissue. This way will help to cover up the root surface area. Another way is to put a bonded filling to repair the tooth. Utlimately, the source of the problme needs to be correct which is to minimize the abrasion of the toothbrushing. Patient can use a toothbrush with a soft bristle. Also, method of toothbrushing can be modified. Patient can use the toothbrushing method called the roll method which is more gentle on the gingiva. By repairing the tooth, it not only restores the cosmestic aspect of the tooth but also protects the tooth from further damage in that area.
