How long will my restoration last?

You may have paid a lot of money for your restoration and it is  a perfectly valid question to ask, how long is it going to last?

However, this is an extremely tricky question to answer.

Imagine going into a car dealership, buying a new car and asking the dealer, when is this car going to breakdown? There are so many variables outside of the car dealer's control,  it is impossible to answer that question with a large degree of confidence.

Your dentist should be able to give you an average estimated life expectancy for your restoration,  based on their personal experience and evidence from professional dental literature. The actual time your restoration is going to last, is influenced by the factors outlined below:

Environmental Factors

These are conditions inside the mouth, not under the direct control of the dentist or the patient. 

Dentist Factors

These are factors largely based around the skill and training of your dentist.


The dental material(s) chosen for your restoration will be based mainly on functionality, aesthetics and price.

Patient Factors

These are factors that are largely under your control, as the patient

The Evidence

The reported lifespans of various treatments and materials in the dental literature is derived from research.
