Fillings

When a tooth is damaged or decaying, a filling can help restore it back to normal function.

There are different types of fillings, each made from different materials. Your dentist will decide on the most appropriate filling for your personal needs and for the type of cavity that you have.

What is a filling?

A filling is a way of repairing a damaged tooth. Your dentist will first clean out the cavity, removing any decayed parts of the tooth before filling it in with an appropriate material.

Fillings prevent bacteria from entering damaged teeth, minimising the possibility of further problems and decay.

What are fillings made from?

Fillings can be made from a variety of materials. Below is a quick summary of the three main types. The specifics of each type and how these apply to you will be discussed at your consultation with your dentist:

Amalgam

• Made from a blend of metals including tin, silver and copper.
• Relatively inexpensive.
• Dark grey in colour.
• Where well looked after, can last approximately 10-15 years or longer.

Composite

• Made from a blend of glass and resin.
• Tooth-coloured.
• Where well looked after, can last approximately 5-10 years or longer.

Glass ionomer

• Made from powdered glass.
• Forms a chemical bond with the tooth.
• White in colour.
• Flexible and can be used for both temporary and definitive restorations.

Why might I need a filling?

The most common reason for a filling is tooth decay. During a Beaumont Dental check-up, your dentist will check for cavities and assess whether you require any fillings. Other forms of tooth damage that might require a filling include acid erosion, chipping and abrasion (general wear and tear).

How can I avoid further fillings in the future?

Maintaining good dental hygiene is key to minimising your risk of cavities. Your personal practice should include brushing your teeth properly, without being overly abrasive, twice per day and for at least two minutes. Flossing is also recommended.

One of the most important ways to maintain dental hygiene and avoid decay is to avoid sugary food and drink as much as possible. While this includes the obvious food culprits like sweets and sodas, it also includes some less obvious foods such as fruit juices and honey.

Essentially, foods with a high sugar content – even if natural – should be limited as far as possible, especially at bedtime. Current guidelines suggest that less than 5% of our diet should be made up of sugars. Sugary foods are directly linked to the demineralisation of teeth. It compromises the tooth enamel and allows cavities to form.

The great news here is that a low sugar diet also has a host of other health benefits, and you will likely look and feel great while protecting the health of your teeth.

We advise visiting your dentist for regular check-ups. You may also visit the dental hygienist for a professional clean approximately every six months.
