How Long Do Cosmetic Dental Results Last?

Cosmetic dental work usually gets decided on price and appearance. How long the result lasts is the part that gets asked about least and matters most later. What follows covers expected lifespans and the upkeep behind them — general ranges, not a promise about any individual case.
How long results last
Results can last anywhere from a few months to the rest of your life, and it depends on the type of procedure you have and how well you take care of your teeth and gums (Cleveland Clinic).
Approximate lengths by treatment are six months to three years for teeth whitening, five to eight years for dental bonding, and five to 15 years for veneers. Tooth contouring is permanent (Cleveland Clinic).
The upkeep behind the number
Maintaining your smile takes a certain level of commitment, and some treatments — like porcelain veneers — may be irreversible and require replacement every few years (Cleveland Clinic).
That is the part worth weighing before committing to anything. A figure in years describes a range, not a promise about your own mouth. If you are looking at one treatment in particular, there are separate articles here on teeth whitening options and caring for veneers.
