Root canal therapy is a method of saving a tooth that has become infected or inflamed down inside. In the old days, there was no way of saving such a tooth. The common remedy was simple extraction. But times have changed and modern rooth canal therapy is as stress-free and painless as getting a routine filling.

Properly done, a tooth treated with root canal therapy should last as long as a normal tooth. The success rate for root canal therapy is 95%!

Tooth Structure

Each of our teeth contains a long, thin strand of dental pulp that extends down to the tooth’s root. If the pulp becomes infected or injured, the tooth’s nerves die and often, without treatment, the tooth can die as well. Root canals are designed to save such damaged teeth. 

If the tooth requiring root canal therapy had a large filling or extensive decay, it may be necessary to cap it with a crown to prevent the tooth from breaking.

Treating a toothache

If the decay reaches into a tooth's nerve tissue or pulp, the bacteria can begin to multiply within the pulp chamber. The bacteria and other decayed debris can lead to a painful "abscess" or a pocket of infection that forms at the end of a tooth's roots. This is the cause of a toothache.

At Keely N. Lawson DDS, root canal treatment can preserve efficient pain-free chewing, normal bite force and the appearance of your natural smile. You will still be able to eat the foods you like.

Saliva serves an important function in oral health and actually the health of your entire body.

Every day, the average human body produces from a quart to an entire gallon of saliva a day! Actually, it is a process of recycling.

Saliva is mostly made of water, but it also includes important proteins and minerals that continously bath your teeth to prevent tooth decay and gum disease and protect your tooth enamel. Saliva even keeps your breath fresh. Saliva also contains important substances necessary for proper digestion of food.

The action of chewing stimulates salivary glands inside your cheeks and mouth to produce saliva. The more forcefully you chew, the more saliva is produced. So the more you use your teeth, the more the body is stimulated to protect them.

Preserve your health

In recent years, scientists have discovered something remarkable—harmful bacteria that live in the small spaces between your teeth and gums are linked to a host of tragic illnesses. For example, the bacteria associated with Alzheimer’s Disease grow in tiny spaces between the teeth and gum (called periodontal pockets). From there, these harmful bacteria can spread along the nerve pathway from the teeth to the brain tissue. When these bacteria are introduced into brain cultures, a substance called beta amyloid is formed, which is a cause of Alzheimer’s Disease. Peridontal bacteria have also been linked to heart disease, Type 2 Diabetes, respiratory ailments, strokes and blood clots, premature babies, low birth weight, and inflammation diseases. Preserve your good health by twice daily brushing and flossing.
