Dental Fillings Are Durable But Don't Last Forever

There are multiple types of fillings made of different materials with varying price points and cosmetic considerations. The Canadian Dental Association suggests asking your dentist which type of filling will work best for you, and what aesthetic and cost implications to consider. Some materials are more durable than others, but none are considered permanent. Both gold and amalgam fillings last a long time without needing correction and can last ten years at the very least. Porcelain and composite fillings can be more fragile — but also more cosmetically appealing.

Constant stress from chewing, clenching, and secondary tooth decay can damage your filling or the tooth around the filling. If a filling chips, cracks or begins to separate from the tooth, decay-causing bacteria can get trapped between the filling and the tooth. This kind of bacteria can't be cleaned away with regular brushing and flossing.

It's important to get a damaged filling treated right away to prevent the bacteria from doing additional damage, such as affecting the nerve. Symptoms of a damaged filling in more advanced states include sharp pain when chewing or intense sensitivity to heat or cold.

Of course you know that brushing twice a day and flossing daily is essential to keeping your teeth — especially those with fillings — healthy. Regular visits to the dentist and professional cleanings twice a year are also essential so that he/she can inspect your existing fillings to detect any early problems. Your dentist can also check for weaknesses in the material, as well as do dental X-rays to look for decay under the filling.

Beware of bad dental habits, such as clenching or grinding your teeth. Your dentist might recommend a mouth guard to help prevent damage to your fillings, as well as protect your healthy teeth and jaw.

Don't wait until a filling hurts to start taking care of it. While fillings don't last forever, you can help them last as long as possible with proper care. Next time you're at the dentist, ask to get your fillings checked and ensure they're in good shape.
