Endodontic therapy, also known as a root canal, is a relatively painless treatment which aims at clearing infection as well as protecting the tooth from subsequent infections.

When a tooth is cracked or has a deep cavity, bacteria can enter the pulp tissue and germs can cause infection. If left untreated, an abscess may form. If the infected tissue is not removed, pain and swelling can result.

This not only puts your jawbones at risk for injury, but it is also detrimental to your overall health. Without the proper treatment, your tooth may have to be removed.

Teeth that require endodontic therapy are not always painful. However, signs you may need a root canal include:

• Severe toothache
• Pain upon chewing or application of pressure
• Prolonged sensitivity to heat or cold
• Dark discoloration of the tooth
• Swelling and tenderness in the nearby gums

Root Canal Treatment

Root canal treatment involves one to three visits during which your endodontist removes the affected tissue. After the tissue is removed, the interior of the tooth will be cleaned and sealed.

Finally, the tooth is filled with a dental composite. If your tooth has extensive decay, your doctor may suggest placing a crown to strengthen and protect the tooth from breakage. 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.

Most teeth can be saved by endodontic therapy. However, tooth extraction may be necessary if:

• Roots are severely fractured
• The tooth does not have adequate bone support
• The tooth cannot be restored
• Root canals are not accessible

Root Resorption

Root resorption is the process in which the body breaks down and absorbs tissue surrounding a tooth. Although this is a rare phenomenon in adults, root resorption in children is natural and enables the roots of baby teeth to dissolve so that permanent teeth can serve as replacements.
