Root Canal Treatment

Root canal treatment is part of our restorative dentistry: it removes infection from inside a tooth and keeps your natural tooth in place.

Why a tooth needs a root canal

When a tooth is cracked or has a deep cavity, bacteria can enter the pulp tissue inside it and cause an infection. If left untreated, an abscess may form. If the infected tissue is not removed, pain and swelling can result. This can injure your jawbone, and it is also harmful to your overall health. An infection inside a tooth will not heal on its own.

Signs you may need a root canal

• Severe toothache when chewing or putting pressure on the tooth
• Lingering sensitivity to hot or cold after the source is gone
• A tooth that has darkened in color
• Swelling or tenderness in the nearby gums
• A pimple or small boil on the gum that may ooze

Some infected teeth cause no symptoms at all and are found at a regular exam or on an X-ray.

What to expect

Root canal treatment involves one to three visits. During treatment, your general dentist or an endodontist (a dentist who specializes in problems with the nerves of the teeth) removes the affected tissue. Next, the interior of the tooth is cleaned and sealed. Finally, the tooth is filled with a dental composite.

1. The tooth is numbed with a local anesthetic, and a small shield keeps it clean and dry.
2. A small opening is made in the top of the tooth to reach the pulp.
3. The infected pulp is removed and the canals are cleaned and shaped.
4. The canals are filled and sealed, and the opening is closed with a filling.

Does it hurt?

With modern anesthesia, most patients find a root canal similar to having a filling. In fact, the treatment usually relieves the pain the infection was causing. The tooth may feel tender for a few days afterward, which over-the-counter pain relievers usually manage.

After treatment

If your tooth has extensive decay, your doctor may suggest placing a crown to strengthen and protect it. As long as you continue to care for your teeth and gums with regular brushing, flossing, and checkups, your restored tooth can last a lifetime. Until the final restoration is in place, avoid chewing hard foods on that side.

Root canal or extraction?

Saving your natural tooth is almost always the better choice: it keeps your bite and jawbone intact and avoids the cost of replacing the tooth. If a tooth cannot be saved, a tooth extraction followed by an implant or bridge may be recommended.
