November 15, 2023

When a cavity forms, it progressively destroys your tooth until you receive a treatment. Generally, dentists recommend dental fillings to eliminate the cavity and restore your tooth. During your teeth filling procedure, the dentist will start with anesthesia, and then they will remove the decayed area of the affected tooth. There are many types of fillings for teeth, and you might be wondering: how long do fillings last? Read this blog to learn all about the filling lifespan and how you can ensure they last long.

How Long Do Teeth Fillings Last?

Generally, dental fillings tend to last for about 10 years. The material of your fillings and how well you take care of them will determine how long they last.

Lifespan of Different Types of Dental Fillings

While dental fillings typically last for approximately 10 years, the different types of fillings have varying lifespans. Amalgam filling lasts for 15 years, which is the longest. Then come the gold fillings, with a lifespan of almost 15 years, followed by composite (7 years) and glass ionomer (5 years). You can discuss which type of tooth filling to opt for with your dentist!

Tips to Prevent Your Filling From Falling Out

In many cases, the dental filling falls out, and this happens for multiple reasons. Bruxism, eating habits, oral hygiene, and your lifestyle are among the factors that could damage your teeth filling. However, you can increase the lifespan of your filling by following these tips:

  1. Keep Up With Your Oral Hygiene
    It is always of high significance to keep up with your oral hygiene. So, whether you have dental fillings or not, you should always maintain optimal oral care. Nonetheless, the responsibility increases when you receive a dental filling. Make sure you brush and floss twice daily for two full minutes in order to protect your teeth. That’s not all — use a soft-bristled brush and fluoride toothpaste so your fillings last longer!
  2. Maintain a Healthy Diet
    What you eat affects your dental health, and it can save your filling from falling out of your tooth. The first thing to do is avoid soda, sugary, acidic, and processed foods to decrease the amount of plaque that develops on your tooth. Instead, pursue foods and drinks that are good for your dental health. By doing so, you can protect your teeth from decay and erosion.
  3. Receive Treatment for Bruxism
    If you have a habit of unconsciously grinding your teeth, it can be pretty damaging to your filling as well as overall dental health. Therefore, talk to a dental expert on how to deal with bruxism. They might suggest nightguards to reduce the effect of bruxism on your teeth.
