When the nerve of a tooth becomes infected, root canal treatment can save the tooth.

Deep cavities allow germs to get into the plup chamber. these germs cause infection, and the pulp dies. A blow to a tooth may also cause the plup to dies and then become infected. an infected tooth will never heal on its own, and as it gets worse, it will continue to be a source of infection untill treated.

Some signs are heat and cold sensitivity, swelling and pain, or a bad taste in your mouth. or, you may experience no sysptoms at all and not realize that you have dental problems.

It depends on the location of the tooth, the number of root canals in the tooth, and how much infection is present. Root canal therapy generally takes between one and three appointments to complete.

Once the plup of a tooth is removed, the remaining tooth structure is brittle and easily fractured. you will probably need a crown to protect the underlying tooth.

Since you're numb when a root canal is performed, you probably wont feel anything during the procedure. most people (about 75 percent) experience no discomfort after this procedure. the discomfort experienced by the remaining 25 percent is usually caused by the infection that made the root canal necessary, not by the root canal.

when a wisdom tooth doesn't have room to grow in properly, it becomes impacted; this means that it's wedges aginst the adjacent teeth. if left untreated, an impacted wisdom tooth can be trouble-free. however, it's more likley that it will develope any of a wide range of problems, which could include:

Infection
Jaw pain and stiffness
Periodontal disease and tooth decay
Tumors and Cysts
Damage to the adjacent secound molars

Early removal of wisdom teeth is often recommended to avoid these problems altogether.

wisdom teeth, also called third molars, are the last of the teeth to erupt. and usually, they're the most troublesome.By the time they grow in- typically between the ages of 15-25- the teeth are already crowded in the mouth, leaving little room for the four additional molars.

A dental exam isn't complete without x-rays, since they show structures and disease processes that can't be seen with the naked eye. if you're concerned about radiation, consider this fact:
the two x-ray examinations you receive at your six-month checkups equal approximately thirty minutes of exposure to the sun on a california beach.
