What is a filling?

A dental filling is a treatment used to restore a tooth when a cavity has developed, to prevent tooth decay from worsening.

Tooth decay occurs when bacteria from food particles get trapped. The bacteria produce acids that will slowly eat away at the tooth until a cavity is formed. Luckily for us, fillings exist, as without them we could be in danger of losing the entire tooth structure. The decay could also reach as far as the tooth root, which would result in needing a Root Canal or even an extraction if the tooth is unsavable.

How would I know that I need a filling?

If you are up to date with your regular dental check-ups, it’s possible that your dentist will know that you need a filling before you even realise it. With a magnified view of the inside of your mouth, small holes can be spotted before they cause you a problem, as well as regular radiographs (x-rays) are taken to identify any cavities.

What types of fillings are available?

‘Silver’ amalgam fillings

These are the option usually offered on the NHS, since they are the cheapest option available but are not the most aesthetically pleasing.

White ‘composite’ fillings

This is a tooth-coloured resin, which once placed are almost undetectable in the mouth amongst other natural teeth. The material is not only used for fillings. It is also great for making cosmetic corrections to the shape and size of the teeth.

Ceramic ‘porcelain’ fillings

Also known as ‘inlays’ or ‘onlays’ this is a high-quality, durable option. They are more suitable for cases of more severe damage or decay but will be more expensive than a composite filling, as they are custom made in a laboratory rather than moulded in chair.
