Dental veneers have the following disadvantages:
- Porcelain veneers can come off or break or chip.
- If your teeth have been drilled, the veneers are irreversible.
- Composite veneers or porcelain veneers do not change colour with whitening.
- Colour matching can be difficult if only one or two veneers are done.
- Need for better oral hygiene is more crucial.
- The veneers may have to be replaced after some years.
- Age and trauma related gum recession can affect appearance.
- People with clenching, grinding and other chewing habits are not the best candidates for dental veneers.
- In the case of people with uncontrolled gum disease, dental veneers can exacerbate the problem.
