When the pulp of a tooth becomes infected or dies, root canal therapy is necessary to save the tooth. It is a comfortable treatment that can save your tooth and keep your mouth healthy. Having bacteria traveling though the bloodstream from an infection in a tooth can cause serious problems in other areas of the body- unbeknownst to you.
Symptoms of infection:
You may realize that you have an infected tooth when—
• the tooth is sensitive to hot or cold.
• the tooth hurts with biting or pressure.
• there is throbbing, severe tooth pain.
• the area is swollen.
• you have a bad taste in your mouth.
Causes of infection:
The pulp becomes infected when bacteria invade the inner layers of the tooth. The tooth pulp is a soft tissue made up of nerves and blood vessels. It is contained in the pulp chamber that extends from the middle of the tooth down through the tooth roots. Infection occurs most commonly through a deep cavity that allows bacteria through the enamel and dentin layers and into the pulp. Sometimes the pulp simply dies due to a fracture or a blow to the tooth.
Crown After Root Canal Therapy:
After a tooth has had root canal therapy, we recommend placing a crown on the tooth. Root canal therapy reduces the strength of the tooth, and a crown can cover and protect it.
How does root canal therapy affect a tooth?
Root canal therapy leaves a tooth brittle and weak. The inner pulp layer of a tooth contains its nerves and blood vessels, so the tooth loses much of its blood supply when the infected pulp is removed and the tooth’s root canals are cleaned out. The tooth is weaker also because only the sides of the tooth are left for support when the center of the tooth is gone. These factors make it much easier for a tooth to break when you bite down on food. Biting and chewing place a tremendous amount of force on teeth, and weak, brittle teeth are especially vulnerable. A crown can prevent these problems by covering and protecting the tooth and restoring its strength and shape.
