The biggest misconception with dental fillings is that they are permanent. Although dental fillings can last for several years, they are subject to wear and can weaken over time if not properly cared for. Many patients wonder how long do tooth fillings last after receiving them. Besides attending regular dental checkups and maintaining a good oral hygiene routine, the type of tooth fillings has a considerable impact on its longevity.


Types of Fillings: Modern Dentistry

Numerous types of fillings are available depending on the tooth that requires repair and your bite. Many people opt for mercury-free composite resin dental fillings as a modern, aesthetically pleasing option to restore their smile.


Composite Resin Fillings

Mercury-free composite resin fillings are a preferable alternative to traditional metallic fillings in many ways. Unlike gold or silver amalgam types of fillings, temperature variations do not affect composite fillings leading to a more pleasant eating and drinking experience. 

White composite fillings are also more natural in appearance, making them ideal for fixing your social six front teeth that are visible when you smile. Unlike metallic fillings, composite resin blends in with your tooth colour for a seamless repair that lasts. 

Another advantage of composite resin fillings is that they can be bonded directly to the tooth. When the cavity or crack is filled with the resin, the tooth becomes stronger. White composite fillings last roughly five to ten years, depending on which tooth they are in, how well you care for your teeth, and what you eat.


The Various Purposes of Dental Fillings

  • Repairing chipped teeth
  • Filling cavities caused by decay
  • Providing tooth protection
  • Replacing older silver amalgam fillings for aesthetic purposes 
  • Cosmetic purposes like altering a tooth shape

When used to repair decaying teeth, dental fillings keep bacteria from entering the cavity and causing further damage. Talk to your dentist about whether a composite resin filling is the right solution for your chipped, misshapen, or decaying tooth.


How Long do Dental Fillings Last?

While repairing your teeth with composite resin is often necessary, you may be wondering, do tooth fillings last? When cared for properly, fillings will last for years, if not decades. If your filling falls out, breaks, or leaks, you will need to book an appointment for a replacement.

 When it’s time to replace a filling, there could be noticeable symptoms, such as increased tooth sensitivity, acute discomfort while chewing, or feeling like something is stuck between your teeth.  There is also a chance you may not realise that your filling has deteriorated, which is why regular six-month checkups with your dentist are crucial.
