No one wants to have a cavity. Only a few avoid them completely. Even those who follow all the recommendations for dental hygiene can be susceptible. Cavities are one of the primary reasons for dental visits, particularly when they signal loudly and painfully as a toothache. Once decay forms, the tooth structure has to be restored with some type of filling.
The cavity is a common problem seen in most dental practices, including my own. When decay breaks through the enamel, a tooth can no longer repair itself. If the decay reaches the inner tooth and the nerve, a toothache is a result. Not all cavities are the same. Nor are the materials used for dental fillings.
