Why you need a Root Canal Treatment

When a tooth has undergone heavy damage from decay, and bacteria has infected the tooth, a root canal treatment is performed to remove the bacteria infection and save the tooth, as opposed to removing the whole tooth. This article explains everything you need to know about root canal treatment.

What is Root Canal Treatment?

A root canal treatment is a complex procedure that is performed to remove inflamed or infected dental nerve tissue from the inside of a tooth, thereby stopping any pain.

When is a Root Canal Treatment Performed?

The dental pulp is the innermost layer of a tooth, and it contains the nerves and blood vessels. On the outside, our teeth are protected by a hard, mineralized layer known as the enamel. Between the enamel and the pulp is the softer dentine, which contains nerve endings originating in the pulp.

When a tooth has extensive cavities or if it gets damaged as a result of an accident, the nerves and blood vessels in the dentine and pulp become exposed to the oral environment, which may cause sensitivity to cold or hot. This problem, if it is superficial, can be treated by simply restoring the tooth with a filling.

However, if this situation persists, damage to the tooth continues and ultimately the pulp tissue becomes inflamed. When this happens, there tends to be severe, continuous pain which does not go away, even after taking pain medication. At this stage, in order to save the tooth from extraction, an option would be to perform a root canal treatment.

Root canal treatment is usually performed in 2-3 appointments of 1 hour each. Some of the steps involved in root canal treatment include:

Reinforcing the Tooth

Teeth that require root canal treatment tend to have very little tooth structure remaining, due to the previous decay or damage. Therefore, they must be reinforced by using a crown, which covers the entire top and sides of the tooth. Reinforcing the teeth with crowns becomes even important for the back teeth, which undergoes very high chewing forces. Otherwise, weakened teeth may fracture as a normal filling is not strong enough to protect the tooth. If the tooth fractures and exposes the root canal filling, the whole root canal may need to be redone as infection may have penetrated the tooth. Therefore, we always recommend for the crown to be done immediately after the root canal treatment to protect the tooth.

At Dental Designs Clinic, we make every attempt to save each tooth from extraction, so that you may continue to use your teeth. In some cases, if the tooth is too badly broken down, extraction may be necessary. We can help with the replacement of the tooth by using a dental bridge, or a dental implant.
