Replacing old metal fillings and crowns

Dental fillings and crowns are used to recreate structure that has been lost to tooth decay, and although they last years, they eventually need replacing. From general wear and tear on the teeth to more cosmetic issues, such as darkening, there are numerous reasons why you might opt to get them replaced.

It’s no secret that bacteria harms teeth, so when a filling has chipped or broken, there are entry points that leave the tooth vulnerable to decay. The bacteria that get into the small gaps are difficult to remove with a toothbrush or interdental brush and decay can develop along the edge of the filling or crown. Decay that is left untreated can infect the dental pulp, which can mean you need a root canal filling or lose the tooth completely.

In the same way, crowns and bridges can fracture and cause problems that are painful and costly. The challenge for the dentist is then to create new ones that look individual and natural, as though they are emerging from your gums like the rest of your teeth.

Keeping on top of your dental appointments is highly important because it will allow your practitioner to spot and sort any issues before they become a big problem. Although you may not be able to tell that your filling or crown is worn, your dentist will be able to identify any weaknesses and devise a treatment plan before the problem becomes more painful and costly.

Replacing a crown

Many people ask whether they should have their crowns replaced, but the truth is that it entirely depends on each individual case. You may need your crowns replacing due to cracks and chips that encourage decay, or you might decide to get new crowns for cosmetic reasons.

Crowns can discolour over time and the edges can become more prominent. This may lead you to opt for a full smile makeover by having new, natural looking crowns fitted. Crowns can also be used to improve the look of the teeth where there is problems with receding gums, overcrowding and missing teeth.

Replacing fillings

It is normally best to change fillings only when your dentist decides that an old one needs replacing. This ensures that you retain the structure of your teeth rather than potentially damaging them when drilling out the old filling.

If you do want to replace an old metal filling, or have to because of chipping or cracking, there are now more natural looking fillings available than ever before. There are several types of tooth coloured material that can be used, and they are mainly made of glass particles, synthetic resin and a setting ingredient.
