Dental fillings are used to repair worn, decayed or damaged teeth.
 
Cleaning your teeth twice a day and enjoying a wide variety of nutritious foods can help to prevent tooth decay and avoid the need for fillings. 
 
Dental check-ups can help to make sure any problems are found and treated early. Ask your oral health professional how often you should have a dental check-up.

Getting a dental filling

When you get a filling, your oral health professional will use a drill and other tools to remove any decay. They will make sure you are comfortable throughout the process. If needed, they will use a local anaesthetic to make sure you don’t feel any pain. (If you are nervous about getting a dental filling, be sure to talk about your concerns with your oral health professional.)

Once any decay has been removed, the hole in the tooth is cleaned and dried, and then filled with a filling material.

Types of filling material include: 
  • dental amalgam (also known as ‘silver’ fillings) 
  • composite resin (also known as ‘tooth-coloured’ fillings)
  • glass-ionomer cement
  • gold
  • porcelain.

Each different material has benefits and limitations. Some types of material may be better than others in certain situations. Your oral health professional can discuss your options with you. 

Some people are worried about having a filling made of dental amalgam because it contains mercury. High levels of mercury are harmful to human health, but the level of ‘free’ mercury (mercury that could get into the body) in set amalgam fillings is so low that it has no effect on health.
