What is a root canal?
A tooth is hollow on the inside and houses the nerve and blood vessels. When the nerve of a tooth dies, or becomes irritated beyond hope of healing, it leads to the formation of an abscess or infection. The resulting abscess destroys bone around the tooth which usually leads to pain when a patient bites down on anything. The root canal procedure is a process by which the dentist or endodontist, a specialist who only does root canals and surgery, opens deep into the tooth known as the tooth pulp. This procedure allows the tooth to be saved from extraction in most cases. The root canal result is similar to removing a splinter in your finger you may encounter from a piece of wood. It allows healing of the soft tissue and bone around the tooth.
Why would you need a root canal?
There are many reasons why a root canal is needed. Some of those reasons are sensitivity to heat and cold, significant tooth pain, tooth discoloration or swelling and tenderness in the gums. The most common reason is a high degree of decay within the tooth. The diseased tooth may cause damage to the jaw bone or cause other problems if the infection spreads. Without a root canal, the tooth may need to be extracted.
