Tooth Decay

Cavities or tooth decay are bacterial infections that work their way through your tooth structure. Left untreated, they can spread to adjacent teeth or into the nerve supply, causing an abscess.

What causes tooth decay?

Tooth decay is caused by plaque (a sticky layer of germs)in the mouth. The germs in plaque turn the sugar in food and drinks into acid, which can gradually damage the teeth.

You are more likely to have tooth decay if:

Group 3133

Gum Disease

Group 3134

Crooked Teeth

Group 3135


Group 3136


Group 3137


What are symptoms of tooth decay?

If tooth decay is not treated, it can cause:

  • Toothache
  • Tooth sensitivity (for example, to hot or cold food or drinks)
  • Brown, black or white stains on the tooth surface
  • Pain on biting
  • Red and swollen gums
  • Swollen face


The treatment for tooth decay involves several important steps to restore and preserve the health of your teeth. The process begins with a thorough examination and diagnosis, where we assess the extent of decay and any associated damage. This is followed by the administration of local anaesthesia to ensure your comfort during the procedure. Next, we carefully remove the decayed portion of the tooth, creating a clean foundation for restoration. Once the decay is removed, we fill the resulting cavity with an appropriate dental material, such as a coloured composite resin or silver amalgam. The filling is shaped and polished to blend seamlessly with your natural tooth structure. Throughout the treatment, we provide patient education on proper oral hygiene practices and dietary recommendations to prevent future decay. By addressing tooth decay in a timely manner and promoting good oral health habits, we can restore the health and function of your teeth and help you maintain a beautiful smile for years to come.
