Can You Get Cavities After a Filling?

Anyone who has visited the dentist before has likely had to have some cavities filled. This is a quick process that removes the diseased area of your tooth and replaces it with a composite filling. As a common procedure, cavity fillings are a good way to get rid of spreading decay on the fly. But are fillings meant to last forever? And, most importantly, can you get cavities after a filling in the same tooth?

Can You Get Cavities After a Filling?

It is still possible to get cavities in the same tooth that has had a filling. Overall, your eating habits and oral hygiene routine can determine whether or not you will deal with future tooth decay. Your dentist in Riverside is here to provide more details.

What are Dental Fillings and How Do They Work?

A dental filling is a material that is placed in the cavity of your tooth. When tooth decay starts to spread, it can create dark spots on the surface of your teeth. This means the part of your tooth is starting to rot away. In order to prevent it from spreading further, the dentist will carve the infected part out of your tooth. This leaves behind a hole or a cavity, which is then filled with a composite material.

If you have a toothache due to dental decay, you may need more than just a simple fillings procedure. Infections that advance to the root and pulp of the teeth may require a root canal.

Can Teeth with Fillings Still Get Cavities?

Unfortunately, yes. Just because a tooth has had a filling in one area does not make it immune to the spread of decay in another. You must still practice good oral hygiene by brushing and flossing daily to get rid of harmful bacteria.

At the end of the day, the leftover food particles on your teeth contribute to plaque. When you don’t brush your teeth before bed, these particles become harmful bacteria, causing a layer of plaque on your teeth. This is a hard and sticky substance that leads to decay. Without proper dental care, you are still at risk of getting cavities even after a dental filling.

How Can Cavities Be Prevented?

The best way to ensure that you do not continue getting cavities after you’ve had a filling is to invest in better oral healthcare. You can prevent cavities by brushing and flossing every day, in addition to following these tips:

Rinse your mouth regularly. Use mouthwash to rinse your mouth, getting rid of loose particles and bacteria in your mouth.


  • Use fluoride toothpaste. Fluoride helps get rid of plaque and it creates a healthy protective layer over your teeth. Brushing with fluoride toothpaste can help keep the cavities away.
  • Use dental sealants. Kids and adults alike can invest in dental sealants, which are thin protective plastic sheets that go over the surface of your teeth. This keeps food and other harmful substances from getting onto the teeth and can last for several years!
  • Eat healthier foods. Food and beverage items that are packed full of sugar, calories, and acidic properties can wreak havoc on your mouth. A healthier diet can put you at a lower risk of cavities altogether.

If you suspect that you are developing a cavity, or you are at risk for cavities, visit your local dental expert right away and consider the best treatment option to prevent the spread of infection.
