What Causes Sensitive Teeth?

May 26, 2014


There are various triggers that cause people to have sensitive teeth. It can be anything from taking a bite of food to hot or cold temperature sensitivity from ice cream or coffee.

But what exactly is the cause? It may be linked to one of the following:

  • Tooth decay is a common cause of tooth pain. Bacteria in your mouth form acid that breaks down the teeth, eventually resulting in the form of a cavity. The cavity then causes destruction of the hard tissues of the teeth. When the hard tissues break down, a hole is formed in the teeth that cause intense and uncomfortable pain.
  • Another cause of sensitive teeth can be gingival recession. This type of pain differs from that of a cavity. It comes in short, sharp aches, usually set off by hot, cold, or sweet food. Gingival recession is a form of gum recession where the roots of the teeth become exposed. This is caused by a loss of gum tissue.
  • A cracked tooth is another cause of sensitive teeth, and has a different pain level than a cavity or gingival recession. A broken or cracked tooth causes a very painful toothache. Inside the tooth is the inner soft tissue called the pulp which contains the nerves and blood vessels. This explains why the pain is so severe when the tooth is cracked. When chewing, a sharp erratic pain will subside causing a very painful toothace.
  • Wearing down of the enamel, roots, and fillings of the teeth also causes tooth pain. Fillings can wear down or break, while enamel can be worn down or abraded from brushing too hard.

A lot of these conditions that cause sensitive teeth can be avoided with proper dental care. However if you do have pain that requires the attention of a dentist, it is always best to get it checked out sooner rather than later.
