Is cosmetic dentistry permanent?

Most cosmetic dental treatments are long‑lasting rather than truly permanent, and their lifespans vary.

Professional whitening results usually last from several months up to a few years, depending on diet, smoking and oral hygiene. Composite bonding may need refreshing after around five to eight years, while porcelain veneers and crowns can often last ten to fifteen years or more with good care. Orthodontic treatments, such as clear aligners or braces, can offer very stable results, but only if you wear retainers as advised to prevent teeth from moving back.

Your lifestyle, bite, grinding or clenching habits, and how often you see the dentist will all influence how long your new smile looks its best. A good cosmetic dentist will always explain realistic longevity before you commit to treatment.
