An effective way to fix minor damage and decay is with a dental filling. It helps restore the structure to its former glory, and better yet, your results often look just like natural! However, since they will experience daily pressure from eating, they won’t last forever. You will need to get it replaced, but when should you expect to? Here’s more about the lifespan of this treatment.

So, How Long Will My Dental Filling Last For?

There are several different types of fillings, from amalgam, porcelain, and composite. Many practices only offer the last two as they can be matched to your smile, allowing them to blend in much easier and not look as obvious as metal does.

If you get this restoration made from ceramic or porcelain, then the average lifespan is up to 15 years. Composite resin can last up to seven years. However, this can vary based on your diet and oral hygiene routine.

When Do Fillings Need to Be Replaced?

As was mentioned above, fillings can last for a long while, but they may need to be replaced sooner if they’ve fallen out or have noticeable damage. However, you can tell yours is reaching the end of its lifespan if you experience:

  • Increased tooth sensitivity as the inner structures become exposed.
  • Discomfort when eating, as chewing can shift your restoration.
  • Food gets stuck in your tooth since an opening was created after a filling became worn.

What Can I Do to Make My Dental Filling Last?

That being said, you should make sure you treat your smile well after you get this treatment. Doing so will help you avoid needing another one and keep your results strong. An easy way you can do this is by brushing and flossing. These simple habits remove plaque that causes decay in the first place. If you grind or clench your teeth, then getting a nightguard can prevent wear and tear that may impact the integrity of a tooth.

You should also have routine visits with your dentist! Checkups and cleanings are great ways to make sure your oral health is in great shape. They will be able to watch for signs of problems and give you the prompt treatment you deserve.

 Better yet, they will also make sure your restoration is going strong. If there are any worries about it, then you’ll be told about them before you get any serious complications. That way, you feel confident your grin is the best it deserves to be.
