Dental Fillings in Canterbury

Treatment begins with a physical examination of the mouth, teeth and gums to assess the damage and determine which type of dental filling will be suitable for you. Your dentist will then explain the next steps, giving you the chance to ask any questions you may have.

Depending on the type of filling and your personal preference, we may apply a local anaesthetic before cleaning the tooth, removing the decay and placing the dental filling material on the damaged surface. The filling is hardened using a blue wavelength light and any edges are smoothed over to ensure comfort and function.

What are the different types of dental fillings?

There are several different types of dental filling. Your dentist will advise which type is suitable depending on the location and severity of the damage, among other factors.

The different types include:

Composite filling: These tooth-coloured fillings made from plastic and acrylic resin material are a popular option for small to moderate restorations.
Ceramic filling: These tooth-coloured fillings made from porcelain are durable and typically used for larger cavities.
Glass Ionomer filling: These semi-permanent fillings release fluoride into the tooth to help protect against additional decay and are most commonly used with younger patients.
Gold filling: These fillings made from gold-based compounds are extremely durable and strong, but also more costly

Are tooth fillings painful?

In most cases, patients are administered a local anaesthetic during the filling process which numbs the area to manage discomfort. You may experience some mild sensitivity in the days after the procedure, particularly with large fillings, though this can be eased by brushing your teeth gently and using toothpaste and mouthwash for sensitive teeth.

When do dental fillings need to be replaced?

Depending on the type of material used, fillings generally last between 5–15 years. Stress caused by chewing, grinding and biting will gradually erode your fillings, providing an entry point for bacteria in your teeth. It’s important to visit your dentist regularly to monitor the condition of your fillings and replace them if necessary.
