The thought of undergoing a root canal can be intimidating, but root canal treatment is similar to filling a cavity and can save a damaged tooth from extraction. There are several signs you may need a root canal. Knowing these signs gives you an opportunity to see a dentist asRoot Canal soon as possible so your tooth can be spared. Dr. Joel Johnson is your Columbia, SC, dentist for root canals.

Root Canals

Root canals can strengthen and restore teeth damaged by infection that would otherwise need to be extracted. Teeth damaged by infection can become too weak to perform normal biting and chewing functions. Consequently, there is a tendency to avoid using those teeth, which puts additional strain on surrounding teeth that have to compensate for the weaker teeth. Once the root canal procedure is complete, the previously infected tooth will be free of infection and will be strong enough to perform normal biting and chewing functions again.

When the soft pulpy center of a tooth becomes infected, the infection can spread down through the root and form an abscess below the tooth. An untreated abscess can cause the infection to spread to other teeth and even the jaw bone, resulting in further oral health problems. During root canal treatment, the infection is removed from the interior of the tooth and root. The area is thoroughly cleaned out, then filled in and sealed with dental filling, much like filling a cavity, and the tooth is restored.

Root Canal Signs

Several problems in the mouth can be indications of the need for a root canal. If you develop any of these problems your Columbia dentist can examine your teeth and determine if a root canal is needed. Some of the signs you may need a root canal include:

  • Developing a severe or persistent toothache
  • Developing severe mouth pain
  • Experiencing sharp pain when biting or chewing food
  • Developing persistent pain or pressure in the mouth
  • Experiencing tooth sensitivity when eating or drinking hot or cold foods and beverages

Benefits of Root Canals

There are multiple benefits to having root canal treatment. A major benefit is avoiding extraction of damaged teeth. Another benefit is how relatively simple the procedure is to perform as it is quite similar to filling cavities in teeth with decay. Additional benefits of root canals include:

  • Avoiding extraction of teeth
  • Strengthening damaged teeth
  • Restoring regular tooth functioning
  • Preventing the spread of infection to other teeth
  • Alleviating tooth pain, discomfort, and sensitivity

There are several signs you may need a root canal, such as sharp pain when biting or chewing food. If you have any of these signs it is important that you see a dentist as soon as possible. Having root canal treatment in time can spare your tooth from extraction.
