If enamel has been worn off or damaged, then it will lose its protective function and the dentine will be exposed. The dentine has many fine dentinal tubules connecting to the pulp. The patient will suffer sharp pain when these tubules are stimulated.
To protect enamel from damage, you should not brush with a toothbrush with bristles that are too hard, or brush with excessive force since it can abrade the enamel of teeth. Also, you should avoid frequently eating or drinking highly acidic food or beverages. Frequent grinding of teeth is not recommended either.
Apply topical fluoride on the tooth surface or perform a filling according to the condition in order to obstruct the exposed dentine tubules.
Use desensitizing toothpaste to relieve tooth sensitivity. You should consult your dentist before purchasing or using this type of toothpaste.
Use a “mouth guard” made by the dentist to avoid further attrition of teeth.
