Why You Need a Root Canal

Why You Need a Root Canal At the center of our every tooth is a natural cavity. Saving a tooth that has been severely damaged, has been infected, traumatized, injured or has decay usually involves the root canal therapy. This therapy is the process of removing the nerve and the pulp of the tooth where the damage and infection has occurred. After the removal, it is then thoroughly cleaned and sealed.

The Healthy Tooth

A healthy tooth naturally has a natural cavity which is full of healthy nerves, blood vessels, and connective tissues. Inside the teeth’s root canal is the pulp. The pulp carries important structures and elements that are essential in keeping the tooth healthy as it acts as the supplier of moisture to the whole tooth. Moisture keeps the tooth flexible. The pulp also supplies a substantial amount of healthy blood, which delivers elements that naturally repair and restore the tooth from damages and infections.

When Tooth Injury Occurs Root Canal is Necessary

When a tooth suffers injury, the pulp is usually damaged and irritated, creating an infection inside. The infection that occurs then turns into pain and discomfort. There are many ways the pulp gets affected. It can be trauma, tooth decay, or a hard blow to the mouth that reaches the tooth. All of these have a big possibility of damaging the pulp.

Tissue Damage Repair

When the mentioned damages occur, root canal therapy comes into the picture. This therapy repairs the tooth by removing the damaged tissues. First in the whole process is cleaning the cavity. Certain chemicals are then applied to dissolve the organic materials present. Medications are also used to disinfect the area of any bacteria.


After all the cleaning is done and when the root canal is fully disinfected, a canal filler is applied to fill in the gap created by the cleanup. Canal fillers are usually materials called Gutta Tercha. The Gutta Tercha is made up of latex materials that easily fills up the canal and expands to seal it, further preventing any bacteria and any other elements from entering the canal. Once sealed, there is almost no way the it gets infected.

Post Root Canal Therapy

After the completion of a root canal therapy, medical professionals highly recommend to put some protection for the tooth. Because the tooth becomes brittle and can get easily fractured after the lost of pulp tissue that does the natural healing processes, the tooth needs some kind of build-up protectants and crown.

To know if you need a root canal or need to consult a dentist about having one, take note of the following:

  • You see abscess in a tooth
  • You have painful swelling that affects your whole or any part of your head and face
  • Bone loss somewhere in the root of the tooth
  • You have hole in the tooth that drains fluid into the skin

When you have infections and pain within a tooth, opting for a root canal can definitely save a tooth. If you have seen or felt any of the abovementioned signs, you need to see a dentist. Having a professional examine your teeth will help you a lot even in cases that you don’t need a major tooth procedure.
