Root Canal Therapy in San Marcos

What Is a Root Canal?

A root canal is the gold standard treatment for a tooth infection. An infection can be caused by advanced tooth decay or dental trauma which causes pulp inflammation. Dental pulp is located at the center of the tooth, where it’s connected to blood vessels and nerves.

This is why infections are often very painful unless the nerve has died. Root canals restore your tooth’s health by removing the tooth’s pulp, along with all of the infected nerve tissue, down to the root. 

The pulp is replaced with a gutta-percha filling and the weakened tooth is usually protected with a dental crown. Contact us at Tree of Life Dentistry to schedule a consultation.

The Root Canal Process

Dr. Shridhar will take x-rays of your tooth to confirm the presence of an infection and see exactly how far it has penetrated through the tooth.

Anesthetic & Sedation Options

We will administer a local anesthetic to numb your mouth and if you prefer, you can also be sedated. This will help relax you and relieve dental anxiety.


Once the mouth is numb, we will create an opening in your tooth to access the pulp chamber and remove the infected pulp.

Canal Cleaning

Using a series of files, the tooth’s canals will be thoroughly cleaned so no bacteria is remaining.

The access hole now needs to be sealed either with a filling or a dental crown.

Types of Root Canals


This is a root canal that is performed on the front teeth. These teeth are much thinner with fewer canals than the rear teeth. This usually means less anesthetic is needed. Since these teeth have as little as one canal per tooth, the process of removing the pulp and cleaning the canals is much faster and may take fewer appointments. A crown is not usually necessary.


This is a root canal performed on the back teeth, where each tooth can have up to 4 canals. Posterior root canals take longer and, in some cases, may require more than one appointment to ensure that all of the canals have been detected and thoroughly cleaned. A dental is usually placed over the tooth for additional protection.

Do Root Canals Hurt?

No! Despite popular belief, root canals cause no more discomfort than getting a filling. In fact, they actually relieve the pain associated with a tooth infection. The notion that root canals are painful is a longstanding myth that dates back to a time before the advent of modern dental techniques and anesthetic options.

Do I Need a Dental Crown After Getting a Root Canal?

We almost always recommend placing a dental crown over posterior root canals. This is because the rear molars are used for chewing and need to withstand a lot of force. Since a root canal treatment weakens the tooth, it’s very important that the tooth has added protection and reinforced strength so it doesn’t break when you eat.
