A toothache is described as a soreness, or ache in or around a tooth and it is a frustrating and unpleasant experience. In addition to sharp or dull pain, your tooth may be sensitive to temperature or cause pain when chewing or biting.
Amongst the things that might cause a toothache, the most common are:
Tooth Decay - refers to erosion and cavity formation in the outer surface (enamel) of the tooth. Once the decay begins to progress toward an infection, you may start experiencing pain in your tooth.
Gum disease - is characterized by infection of the gums. More specifically, with gingivitis, the gums become inflamed and become hot, red, and swollen. When an infection occurs in the gums, periodontitis occurs. Eventually, if left untreated, the teeth become loose and will need to be extracted.
Impacted Tooth - Teeth can become impacted when they are prevented from moving into their proper position in the mouth by other teeth, gums, or bone. The most common teeth to become impacted are the wisdom teeth because they are usually the last to erupt. When the jaw cannot accommodate these extra teeth, the teeth remain stuck under the gum. This impaction can create pressure, pain, and even jaw soreness.
Dental Abscess - usually results from an untreated cavity caused by the buildup of bacteria inside the pulp chamber. The infected tooth then tries to drain itself out of the very tip of the tooth root. The pressure from the draining infection causes a constant pain that is worse when chewing or when touched. If left untreated, the pain can become severe with swelling.
