root-canal-300x199 Root Canal TherapyRoot canal therapy refers to an endodontic procedure that’s performed on a tooth that has extensive decay or that’s suffering from high levels of infection. The treatment procedure involves the removal of nerve and pulp inside the root canal after which the tooth is cleaned and then sealed.

The root canal is the cavity located in the center of the tooth. The pulp and tooth’s nerves lie within the canal. Once a tooth has emerged through the gums, the nerves cease being vitally important to the tooth’s health. The only function that nerves serve at this point is sensory, so in case of an infection, it’s quite safe to remove the nerves.

Why it’s necessary to perform root canal therapy

When nerves or pulp incur damage, bacteria will start to multiply in the pulp chamber and cause infections. When the infection spreads to the tip of the root,

  • An abscess (pus) will form.
  • The area will swell and this swelling might spread to other parts of your face, neck and head.
  • You’ll experience bone loss.
  • The tooth might start draining into the gums, cheeks and skin.

What factors cause damage to the nerve and pulp?

Nerves and pulp of your tooth will become inflamed or infected as a result of:

  • Deep decay
  • Multiple dental procedures performed on the same tooth
  • Large dental fillings
  • A cracked or chipped tooth
  • Traumatic injury to the face or jawbone

How will you know when you need a root canal treatment

If you have any of the following symptoms, you might need a root canal procedure:

  1. Your tooth experiences pain when you chew or apply pressure
  2. There’s prolonged sensitivity and pain after exposure to heat or cold

  4. Your gums swell and feel tender
  5. You have a persistent pimple on your gums or one that keeps recurring

The procedure

Root canal therapy can be performed on one or more visits to a dentist’s or endodontist’s office through the following stages:

Step one

X-rays are taken to show the root canals and to check for infection in the bone.

Step two

The area surrounding the tooth will be numbed using anesthesia. A rubber dam is fitted around the problematic tooth to keep it dry during treatment.

Step three

The dentist or endodontist will drill an access hole into the tooth through which he will remove pulp and decayed tissue. This process is done using files of different diameters. During the filing, sodium hypochlorite and/or other medications will be used to flush the area.

Step four

When the tooth has been thoroughly cleaned out, it’s treated and sealed. Sealing paste and gutta percha, which is a rubber compound, are applied into the root canal cavity. The exterior hole that the dentist drilled is also filled with tooth filler.

Step five

Depending on how weakened your tooth is, you might require to get a crown fitting to protect the repaired tooth.

Are root canals painful

Anesthetic is administered to numb the area during a root canal, therefore you shouldn’t experience any pain.

After the treatment
