Root Canal Treatment

Virtually painless With Unmatched Precision

A 'root canal' is the term that refers to the natural cavity or space within the center of the tooth. It is made up of the pulp chamber which provides nutrients and nerves to each tooth and the 'canals' that connect to each other or to the surface of the root of the tooth. At Zenith Dentistry, a root canal is done with unmatched precision to treat and save a tooth that is damaged, infected or badly decayed. The treatment involves (1) removal of the nerves and pulp and (2) cleaning and sealing the infected area inside the tooth.

Modern root canals are virtually painless.

To make sure we reach our goal, Zenith Dentistry has always relied upon the latest, most state-of-the-art technology available.

The Truth About Root Canal and Cancer Debunking the Myth

While there are plenty of undisputable resources about the effectiveness of root canal (endodontic) treatment, misinformation continues to circulate online. Zenith Staff continuously work on educating the public about root canal safety while debunking the myths that root canals cause cancer or other health problems. To date, there has not been one valid, scientific evidence linking root canal-treated teeth and disease elsewhere in the body. The American Association of Endodontists (AAE) states that there is no causality between root canals and cancer; just because a person has experienced both doesn’t mean a cause-and-effect relationship exists. In fact, a 2013 study published in a journal of the American Medical Association (JAMA Otolaryngology—Head & Neck Surgery) found that a patient’s risk of cancer doesn’t change after having a root canal treatment. Additionally, researchers found that patients with multiple endodontic treatments had a 45% reduced risk of cancer. Researchers found that patients with multiple endodontic treatments had a 45% reduced risk of cancer. “As dental professionals, we know there is no evidence of a link between root canal treatment and cancer or other diseases,” said AAE President Dr. Gary R. Hartwell. “It is in the best interest of patients to understand there is no valid, scientific evidence linking root canals to such health problems, and also to understand the advancements in modern dentistry that make endodontic treatment predictable, effective and successful.” The AAE offers dental professionals, the media and patients with authoritative and reliable information on root canal safety on their website.

A cavity in the tooth leaves an opening where bacteria can enter and multiply. Left without treatment, these bacteria cause infections and form pockets or abscesses filled with pus up at the roots of the tooth. This causes severe pain and swelling that could spread to other areas of the face or head. Serious infections bring about bone loss around the tip of the tooth's roots. Teeth can become damaged and infected due to severe decay, repeated dental procedures, cracks in the tooth or trauma to the face. Constant pain, swelling and tenderness of the gums, prolonged sensitivity to heat or cold and discoloration of the tooth are signs that one may need a root canal. A visit to the dentist will best determine the ways to deal with each particular case.
