Tooth pain without the presence of cavitiesWhy do some people experience tooth pain even though they do not have any tooth decay? How can a tooth be sensitive to heat, cold, acid or sugar? First, it is necessary to understand the structure of a tooth. The dental pulp is the central part of a tooth. It is composed of tiny blood vessels and nerves, which are keeping the tooth alive. The pulp is linked with the main nerve from the end of each root. Thanks to this connection, the tooth has the capacity to receive and send signals. |

The cause of tooth sensitivityTiny channels called tubules connect the pulp to the outer layer of dentine. The openings of these small channels act like receptors of sensations. These receptors are normally well protected under their “armour” (the enamel and cementum). But when this protective layer is no longer sufficient to seal the tubules, receptors are directly exposed and the sensations are virtually instantaneous. The tubules can easily be uncovered:
Thus, even without tooth decay, the weakened teeth can feel sharp and sudden pain. Fortunately, there are several methods to correct this problem. |
Ways to reduce or eliminate dentinal sensitivityFirst, it is necessary to desensitize your teeth as soon as possible. The use of toothpaste for sensitive teeth will temporarily seal the tubules and stop these sudden pains when in contact with stimuli. The use of a mouthwash for sensitive teeth may also help you. |
