In some cases, improving your dental hygiene game at home can stop tooth sensitivity. When kept clean enough to prevent more erosion and decay, your enamel can actually heal. This process is helped tremendously with fluoride treatment. Fair warning though, dental pain is a natural indicator that something is wrong and it needs to be investigated. If your enamel has become so damaged or decayed that the dentin has become exposed you may be at risk of an infection or abscess.
