How often should an old filling be checked?

Fillings should be assessed during routine dental examinations, with the timing based on your oral health, history of decay, and any symptoms. The dentist can check the restoration’s edges and surrounding tooth and recommend imaging when indicated. Arrange an earlier assessment if the filling chips, loosens, or becomes uncomfortable.

Can a composite filling be used in a back tooth?

Yes. Composite can restore many back teeth, but suitability depends on the size and location of the cavity, the remaining tooth structure, and chewing forces. Some extensively damaged teeth may need a crown or another restoration. Your dentist can explain which option is likely to provide suitable protection.

What if an old filling has a hairline crack but does not hurt?

A visible line does not always mean the filling or tooth is failing, but damage can extend beyond what is apparent on the surface. Avoid judging the severity by appearance alone. A dental examination can help determine whether the area can be monitored, repaired, or should be replaced.

Can amalgam and composite fillings be used at the same time?

Yes. Different teeth can have different restorative materials depending on their condition, location, and previous treatment. There is generally no need to replace every existing filling to make the materials match. Each restoration should be assessed according to its function, condition, and ability to protect the tooth.

Is it safe to remove an intact silver filling for cosmetic reasons?

Removal may be considered for cosmetic reasons after discussing the benefits and risks, but it is not automatically the best option. The procedure can remove healthy tooth structure and temporarily increase exposure to mercury vapour or particles. A dentist can explain the trade-offs and suitable alternatives before you decide.
