It’s been said that root canals hurt, that they cause disease, and that you only need to get one when a tooth is painful. One myth even alleged that root canals cause cancer and other diseases. With stories like that swirling around the world of dental care, it’s no wonder people dread root canals. But there’s good news! All those myths have been busted. So if your dentist sits you down to talk about when to get a root canal, don’t run for the door.

Every tooth consists of three different layers. The outermost and hardest layer is enamel, and the second layer is dentin. The third is pulp, which is the cavernous space where the live tissue and nerve of each tooth is located.

If for any reason the pulp space( pulp tester ) is exposed to the outside, the tissue becomes contaminated and eventually infected. The exposure of pulp happens in many circumstances, such as when you have a large cavity or a fractured tooth. Your dentist can explain the exact reason for damage to this tissue. In these cases, the treatment is usually root canal treatment.

Your teeth are strong, but poor dental care can cause the protective enamel that encases your teeth to break down. When this happens, your teeth become sensitive and more vulnerable to fractures and cavities. This is when your tooth’s root can become infected. Each tooth has soft tissue that runs through the tooth’s canals. The tissue is made up of nerves and blood vessels, which provide vital nourishment to the tooth. When a cavity or fracture is left untreated, that pulpy, soft tissue becomes infected and causes pain – that’s when to get a root canal.

Root canals are a common procedure used to save your tooth once infection sets in. If untreated, the infection can spread and cause damage to surrounding bone. Once this happens, there’s a greater risk of losing your tooth.

To remove the infection and stop it from spreading, a small opening is created at the top of the tooth. From this opening, the tooth’s nerve is removed from the canal, and the inside of the tooth is cleaned before the canals are filled with a rubber-like material. Filling in the now-empty canals helps to seal them from future infection. Once complete, a temporary filling is placed onto the tooth until a permanent filling or crown is ready.

Swelling around your gums and lips will last for a few hours after the root canal, and lingering swelling can last for a few days. Don’t be alarmed if your tooth is still sensitive. This is normal following a root canal, but talk with your dentist about what to expect during recovery. Avoid chewing hard foods until a permanent crown is put on, and talk with your dentist about long-term care for the afflicted tooth. Root canals have a high success rate, but like all of your teeth, they can be damaged if they are not taken care of properly. Good oral hygiene and regular visits to the dentist are key to maintaining the condition of your teeth whether you’ve had a root canal or not.
