Tooth decay is a problem that most of us face today. A tooth filling is done to restore your damaged tooth and give back its strength. However, tooth filling is not a permanent solution, and it has to be replaced. So, how many times do dental fillings need a replacement?
As per our West Des Moines dentist, it depends on the type of material used for filling. If you have amalgam fillings – made of a mixture of metals – they might last for about 15 years or more. The composite filling might be more durable, but they can last not more than 10 – 12 years. Some fillings might go on longer, while some might need a replacement sooner than expected.
