Fillings are used to repair a hole in a tooth caused by decay.

Before appointment:

Please tell us if you have had any problems in the past when getting fillings [if applicable].

We will explain where the tooth needs filling and why, any possible complications or associated risks and answer any questions that you may have. Once you are happy with the treatment plan, we may ask you to sign the consent form before we proceed with the treatment

Please be aware that some teeth with deep decays may need further treatment of root canal treatment and crown. We will discuss this with you if that’s the case.

During appointment:

  • We may need to numb the area to be treated, usually with injections of local anaesthetic
  • Then we will remove any decayed or weakened parts of the tooth
  • Next, we will shape, clean, and dry the remaining tooth so it can take the filling
  • Finally, we will fill the cavity with a composite (white) filling and then check that your bite still feels right when you put your teeth together.

After treatment:

  • The local anaesthetic will make your gums, tongue, cheeks and even your lips feel numb for several hours. Until this wears off, you may have some difficulty talking, chewing and drinking. As sensation returns, you may feel some tingling. Avoid chewing on the side of filling until numbness lasts, partly to protect your filling but also to prevent accidentally biting yourself
  • The injection area may feel sore for couple days
  • For up to a week after your filling, your tooth may be more sensitive to cold and heat. If it gets much worse or goes on for longer or keeps you up at night, tell your dentist – this could indicate changes to the nerve, which may need treatment


Fillings are safe and effective, however, some people might experience discomfort or some tooth sensitivity afterwards. After you get your filling, your face may still feel a bit numb for several hours after. You may have a bit of difficulty eating or talking but that feeling should subside and resolve itself within a few days.

If you are experiencing extreme pain or discomfort including fever, redness or swelling that continues over a week, you should call your dentist right away.

  • Brush your teeth twice a day with fluoride toothpaste and the right toothbrush.
  • Floss daily
  • Cut back on sugar and acidic drinks
  • Visit your dentist regularly for checkups and cleaning
  • Ask your dentist how likely you are to get cavities
  • Drinking plenty of water during the day helps

If you are unhappy with the appearance of your old metallic fillings, you are able to replace your old silver filling to a composite (white) filling if you would like. This can be done by simply replacing the old filling with a new one.

White fillings are known as composite resin fillings and they closely resemble the colour of your tooth. The benefit of these tooth fillings are that they are virtually imperceptible when compared to natural teeth.

Similarly, to your current filling, they restore the function of a tooth’s structure that had been previously damaged by tooth decay with a more natural looking material.
