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.
