A minor cavity that damages only the outer layer of the tooth often causes no pain. A chronic toothache can signal a more serious tooth infection, though. Once bacteria reach the interior of the tooth, a root canal in Belmont might also become necessary. A root canal addresses extensive decay by removing the infected dental pulp. The pulp is made of soft tissues such as nerve endings and blood vessels, which is why a toothache can produce significant pain. Antibiotics alone typically aren’t enough to eliminate bacteria in the interior of the tooth. However, a dentist can quickly and conveniently remedy the infection by taking out the dental pulp and replacing it with sterile materials that preserve the integrity of the tooth. Though the tooth can no longer send and receive sensory signals, the preservation of it is often preferable to extraction. To prevent additional decay, a dentist might also attach a crown to the top of the tooth.
