What is a Cavity or Cavities?
The most common cause of a toothache is a dental cavity. Dental cavities (caries) are holes in the two outer layers of a tooth called the enamel and the dentin. The enamel is the outermost white hard surface and the dentin is the yellow layer just beneath the enamel. Both layers serve to protect the inner living tooth tissue called the pulp, where blood vessels and nerves reside. Certain bacteria in the mouth convert simple sugars into acid. The acid softens and (along with saliva) dissolves the enamel and dentin, creating cavities. Small shallow cavities may not cause pain and may be unnoticed by the patient. The larger deeper cavities can collect food debris. The inner living pulp of the affected tooth can become irritated by bacterial toxins or by foods that are cold, hot, sour, or sweet-causing toothache. Toothache from these larger cavities is the most common reason for visits to dentists.
How do you treat a Cavity?
Treatment of a small and shallow cavity usually involves a dental filling. Treatment of a larger cavity involves an onlay or crown. Treatment of a cavity that has penetrated and injured the pulp requires either a root canal procedure or extraction of the affected tooth. Injury to the pulp can lead to death of pulp tissue, resulting in tooth infection (dental abscess). The treatment of an infected tooth is either removal of the tooth or a root canal procedure. The root canal procedure involves removing the dying pulp tissue (thus avoiding or removing tooth infection) and replacing it with an inert material. The procedure is used in an attempt to save the dying tooth from extraction.
