A common treatment among patients, dental fillings are crucial in maintaining proper dental care. Through years of poor oral health, many people will succumb to tooth decay and subsequently, cavities will begin to form in the mouth. Should this be the case, Etwall Dental Practice experts will recommend fillings. Dental fillings are used to repair the cavities that are created. There are many different types of dental fillings, so we will always encourage patients to come for a consultation before offering the filling we consider clinically necessary.

What is a tooth filling?

Fillings aid the restoration of teeth that are damaged by decay, helping achieve normal function and shape. As aforementioned, there are many different types of filling materials that can be applied.

What types of dental fillings are available?

Dental amalgam is the most common type of filling, made from a mixture of different metals including mercury, silver, tin and copper. Silver in colour, dental amalgam is the strongest direct restorative material and is often used on your back teeth.

For any front teeth, your dentist may suggest a tooth-coloured composite filling, made of a resin and glass mixture. A more discreet option, composite fillings will chemically bond to your teeth, allowing for more support.

Alternatively, glass ionomers may be used. A powdered glass that forms a chemical bond with your teeth, glass ionomer fillings release fluoride that helps prevent further tooth decay. A fairly weak filling in comparison to others, glass ionomer fillings will often be used on ‘non-biting’ surfaces such as around the ‘necks’ of the teeth.

Once a consultation has taken place at Etwall Dental Practice, our dentists will offer the type of filling that’s most appropriate for your medical needs.

What steps are involved in filling a tooth?

Our dentists will firstly ensure you’re completely comfortable with the treatment, answering any questions you may have prior to commencement. Once relaxed, your dentist will administer a local anaesthetic, numbing the area, as they go on to remove any decay from the problem area using either a drill, air abrasion instrument or laser. When the tooth decay has been removed, your dentist will apply a filling material directly to the cavity. Once shaped, the filling material will be cured with ultraviolet light.

For tooth-coloured fillings, your dentist will apply the material in layers. Each layer will be cured with the same ultraviolet light. Once the multi-layering process is complete, the fillings are shaped into the desired result and trimmed of any excess material. The final restoration will then be polished.

How long do fillings last?

The longevity of your filling will depend on the material used. Amalgam fillings are the most durable option, lasting around 10-15 years. Though a more attractive option from a cosmetic point of view, white fillings don’t typically last as long, requiring replacement after about five years. You can improve the lifespan of your filling by practicing good dental care and booking regular dental check-ups.

How Do I Know if I Need a Filling?

Only your dentist can identify whether you have a cavity that should be filled. During a consultation, Etwall Dental Practice dentists will use a small mirror to examine the surfaces of each tooth. Any abnormalities are then checked with special instruments. In some cases, your dentist may X-ray your mouth. All of the above will determine the extent of the damage and subsequent recommended treatment.
