Causes For A Root Canal

root_canal_causesA toothache can have several causes, but the most common reason for the pain is decay that has entered the pulp of the tooth. This causes infection and throbbing pain. A toothache is a serious problem, and can’t be taken lightly. The word ‘can’t’ implies just that. Sooner or later the pain will increase to where a dental visit becomes an emergency.

The infection in a decayed tooth will eventually cause an abscess on the root of the tooth. The manifestations of an abscess become a serious threat to health if ignored. The infection can actually enter the bone of the jaw just as it did the tooth. It will soften the bone and eat it away. This will cause the whole body to develop a systemic infection.

Sometimes an old metal filling has the potential for a root canal. Decay can progress unnoticed beneath the filling until pain or sensitivity begins. Then, decay may have advanced and treatment may be required.

Tooth grinding wears on tooth enamel, and can cause hairline cracks. Eating hard candy or chewing ice can create the same problems. Hairline cracks may not be noticeable to an observer, but bacteria and food particles will eventually enter the cracks. When this happens, decay will begin. If the decay is not halted, a root canal is the result.

Finally, tooth trauma comes into play. Sports injuries, accidental blows and falls that culminate in a hard jaw crunch can all lead to fracture and ultimate decay for teeth.

A root canal is performed by an endodontist. This is a professional who specializes in diseases of the tooth pulp. It can also be performed by a general dentist. It is done when decay has advanced and is likely to kill the tooth.

1. First of all, if there is infection within the tooth it should be stabilized. This will require an antibiotic regimen before the therapy can begin.

2. The dentist will numb the gums so that there is no pain for the procedure. If necessary, an anti-anxiety medication is offered.

3. The dentist will place a barrier between the decayed tooth and the others. This barrier will also prevent liquid and chips of tooth from being swallowed.

4. The dentist will then drill out and remove the infected, decayed pulp from the root of the tooth. He will fill the tooth with medication and a special filling.

When the pulp is removed from a tooth, it is no longer living. When a tooth is no longer sustained by the living pulp, it becomes brittle and breaks off. This is why the next step of the procedure is a crown. Crowns are a replacement for the original tooth structure. When this is accomplished, the new tooth and root are stable for a long time.
