Root Canal Therapy Can Save a Deeply Decayed Tooth

Root canal therapy can save a compromised tooth that would otherwise need to be extracted. Endodontic treatment can also alleviate the pain and discomfort associated with a dental infection. At our Mesa, AZ, office, Drs. Martin Farnsworth and Derek Farnsworth can perform root canal therapy and restore treated teeth with a custom dental crown. Our doctors work hard to ensure your comfort and perform every step of the process in-house.

Root Canal Therapy Explained

When a cavity is left untreated, decay can spread to the innermost portion of the tooth, known as the pulp. If the pulp becomes infected or inflamed, root canal therapy is the only way to save the tooth and relieve discomfort. During treatment, your doctor can remove compromised tissue and reshape the canals before filling the tooth with a rubber-like substance. Your tooth can then be restored with a filling or custom dental crown.

Many patients hesitate to undergo root canal treatment out of fear that it will cause pain. However, this procedure is intended to relieve discomfort rather than instigate it. Over 15 million root canals are performed each day, and these procedures are both safe and highly successful.

Do You Need Treatment?

It is important to visit our office if you experience ongoing tooth pain or notice a deep cavity in your smile. However, keep in mind that not all infections present with noticeable symptoms. Sometimes, only x-rays or other advanced images can reveal a compromised tooth.

You may need root canal therapy if you:

  • Experience sensitivity to hot and cold temperatures
  • Notice swelling in your face or neck
  • Have a bad taste in your mouth
  • Suffer from a severe toothache
  • Detect discoloration
  • Have a pimple on your gums

If decay has spread to the pulp, you will likely need a root canal. An apicoectomy can be performed after root canal therapy if the infection still remains in the root tip. In the case that your tooth is no longer viable, extraction may be necessary. We can provide excellent tooth replacement options with dental implants and implant-supported restorations should your tooth need to be removed.

How Does a Root Canal Work?

There are two steps to a root canal procedure: clearing the inside of the tooth and restoring the tooth. These are usually performed over the span of two appointments.

Our facility is unique because we provide both root canal therapy and crown placement.


To ensure your comfort during the procedure, we can administer a local anesthetic. We can then crease a small pilot hole in the tooth to access the pulp chamber. After removing the infected tissue and the nerve, we can reshape the canals. We will be careful to fully sanitize the tooth to discourage reinfection. This may involve applying antibiotics. 


We will then fill your tooth with a rubber-like material called gutta percha and use a temporary filling to seal the opening. At your next visit, we can restore the tooth with either a filling or custom dental crown.

Our facility is unique because we provide both root canal therapy and crown placement. As a result, you do not have to schedule separate appointments with different specialists.
