What Is a Root Canal Procedure?
If you’ve been dealing with tooth pain, you might be wondering whether a root canal is necessary. Root canal treatment is recommended when the pulp inside a tooth becomes infected or inflamed, usually because of deep decay, a cracked tooth, or an injury. While the idea of a root canal might seem intimidating, understanding how the procedure works can help you feel more comfortable with the process. If you’ve been advised to have a root canal, read on to learn what to expect.
Why Would You Need a Root Canal?
The pulp inside a tooth contains nerves and blood vessels that help keep the tooth healthy. When bacteria reach the pulp, whether from a cavity, a fracture, or trauma, the tissue can become infected. This infection often leads to pain, swelling, and sensitivity. If left untreated, the infection can spread, causing an abscess and damage to the surrounding bone.
A root canal removes the infected or damaged pulp, cleans and seals the inside of the tooth, and helps prevent further problems. By saving the natural tooth, a root canal also helps maintain normal chewing and prevents other teeth from shifting out of place.
What Happens During a Root Canal?
A root canal procedure typically takes one or two visits, depending on the condition of the tooth. The first step is numbing the area around the tooth with local anesthesia to ensure comfort during treatment. Once the tooth is numb, a small rubber sheet called a dental dam is placed around the tooth to keep it clean and dry.
Your dentist will then make a small opening in the top of the tooth to access the pulp chamber. Using specialized instruments, they will remove the infected or damaged pulp from inside the tooth. The canals are then cleaned, shaped, and disinfected to eliminate any remaining bacteria and prepare the space for filling.
After cleaning, the empty canals are filled with a rubber-like material called gutta-percha. This material seals the canals and helps prevent bacteria from re-entering. A temporary filling is placed to close the opening in the tooth until a permanent restoration can be completed.
What Happens After the Procedure?
Once the root canal is finished, your dentist will schedule a follow-up appointment to place a permanent crown or other restoration on the tooth. A crown helps protect the tooth and restore its function, especially if the tooth was weakened or had significant decay. In some cases, a small post may be placed inside the tooth to provide additional support for the crown.
With proper care, a tooth that has been treated with a root canal can last for many years. Good oral hygiene, regular dental checkups, and prompt attention to any new dental issues can help maintain the health of your restored tooth.
