  1. a dentist numbs the infected tooth, an opening is made through the crown of the tooth to the pulp chamber
  2. A special file is then used to remove the infected and unhealthy pulp out of the canals. The canal is then shaped for filling material. Irrigation is used to clean the canal and remove debris
  3. The canal is then filled with permanent material, commonly a material known as gutta-percha is used, this will help keep the canal free of infection and contamination
  4. To seal the remaining opening, a temporary filling is placed on the gutta-percha. The material will remain until permanent filling or a crown is placed on the tooth.
  5. The crown is finally cemented in place.

This hard painless growth are usually present near the premolars and above the location of the mylohyoid muscles attached to the mandible. In most cases, there will be a torus (bony growth in upper and lower jaw) on both the left and right side.

Mandibular tori are usually a clinical finding that required no treatment. Due to trauma, it is possible for ulcers to form around the area of the tori. If removal of the hard bone growth is required your dentist may recommend surgery.

Calcium deposit

Another possible cause of the painless hard lump on gum can be calcium deposits. Calcium deposits can form on bones and teeth, this is called calcification. The plaques adhere to teeth and form plaques which harden to form tartar or calculus. Maintain good oral hygiene may help prevent against this.

Common reasons for tooth extraction include:

  • Extraction of tooth that blocks others
  • Extraction of baby teeth that fail to give room for permanent teeth
  • In cases of radiation therapy in head or throat, teeth in the line of radiation need to be extracted to give way for the radiation
  • Extraction of decaying wisdom teeth (also called third molars)
  • Extortion of infected tooth especially for people who have had organ implants, this is common because of decreased or suppressed immune system.
