Root Canal Therapy

What is root canal therapy?

Root canal therapy is designed to correct disorders of the dental pulp -- the soft tissue inside the tooth that contains nerves, blood vessels, and connective tissue. Teeth with abscessed, or infected, nerves were once removed with corrective therapy. But now, in 95 percent of these cases of pulpal infection, the natural tooth can be saved through modern endodontic procedures. (Also called pulp specialists, endodontists have undergone specialized training in performing root canal therapy.)

What causes pulpal nerve damage?

The most common causes of pulpal nerve damage are:

• Physical irritation - generally brought on by aggressive tooth decay (cavity) reaching down to the nerve or through deep fillings, which allows harmful bacteria to reach the nerve resulting in infection and decay.
  
• Trauma - a blow to a tooth or the jaw can cause damage to sensitive nerve tissue within the tooth.
  

What are the symptoms of pulpal nerve damage?

The following are the most common symptoms of pulpal nerve damage. However, each individual may experience symptoms differently. Symptoms may include:

• Pain in the tooth when biting down.
  
• Tooth pain while chewing.
  
• Oversensitivity of the teeth with hot or cold drinks.
  
• Facial swelling.
  

The symptoms of pulpal nerve damage may resemble other oral health conditions. Consult a dentist, or other oral health specialist, for diagnosis.

Why is root canal therapy necessary?

Without treatment, the infection of the dental pulp will spread to the bone around the tooth, making it not longer able to hold the tooth in place.


Post-Operative Care Following a Root Canal

Once the root canal therapy is completed, there will be changes to adapt to, including:

• Brittleness - a pulp-less tooth is more brittle than a non-treated tooth and great care should be used to avoid fracture and chipping.
  
• Discoloration - a non-vital tooth may become discolored over time, which can be treated with bleaching. In most cases, the discoloration poses no threat to the health of the tooth.
  

In addition, soft tissue inflammation may be a source of irritation in the weeks following surgery. Consult Dr. Hoang or the endodontist for a treatment approach to help control any post-operative swelling and discomfort.
