How Long do Dental Fillings Last For?

Usually, cavity fillings last for about 8 to 10 years. However, many factors contribute to the longevity of life.

  2. Oral hygiene
  3. Diet
  4. Any impact or tooth trauma
  5. Decay near the filling
  6. Bruxism or teeth grinding

Dental fillings last quite long, but not forever. Therefore, it is best to know when it might be needed again.

When Should You Get a Replacement Of Fillings?

There might be a slight chance of not needing a filling renewal at all, but that’s very rare. On average, if you visit every 6 months, the dentist might be able to detect the need to change the filling early.

Your filling may crack up or suffer from wear and tear while eating and lose its function of protecting the teeth contents under it. Sometimes, dental fillings may fall out and need urgent replacement.

It is also possible to not notice a filling oozing out slowly or having problems. That is why regular checkups are essential. Your dentist can catch the issue in the initial stages during a routine exam.

Your dentist has specialized tools to look around the edges of your filling. They ensure that it is still intact in the tooth or not. Another point is the use of dental X-rays to show decay (if any) under the filling or if it’s anywhere nearby.

Types of Dental Filling

Usually, 4 common types of materials are used for dental fillings, namely: gold, composite, amalgam, and porcelain.

Gold Filling

Dental fillings made of gold last between 15 to 30 years- yes, that’s right. This is because gold is the most durable material and withstand years of biting wear and tear.

Silver Fillings

The next in durability and strength is silver. Silver dental fillings last for around 10 to 15 years. Moreover, it is also the most inexpensive option. They are not pure; they have copper, tin, and other metals mixed as well.

Composite Fillings

They comprise resins, a hard polymer with glass or quartz particles. This filling lasts around 5 to 7 years but can stretch up to 10 years. However, their ability to wear out is faster, and they could be better at withstanding pressure compared to gold or silver ones.

Porcelain Fillings

Ceramic or porcelain filling has longevity similar to composite, which is around 5 to 10 years; however, the price aspect can be as expensive as gold ones. Porcelain has the added advantage, just like composites, of matching the natural color of teeth. However, porcelain is much more sturdy than resin used in composite fillings; therefore can last long.
