Quick Answer
Dental bonding is a cosmetic dental procedure that uses tooth-colored composite resin to improve how a tooth looks. It can change a tooth's shape, close small gaps and hide chips, cracks or stains. It takes 30 to 60 minutes per tooth and is painless. Bonding lasts three to 10 years but stains and chips more easily than porcelain.
What the research says
Most bonded front teeth lasted years: in 6 studies of 141 patients with 1,068 composite restorations on worn front teeth, 88% survived over 2 to 10 years and 68% stayed in ideal condition (Aziz IM et al., European Journal of Prosthodontics and Restorative Dentistry, 2024) [2]
Fracture was the main reason for failure: a review of 25 studies covering 75,637 front-tooth composite restorations found annual failure rates of 0% to 27.11%, with fracture the main cause of failure (Shah YR et al., Journal of Conservative Dentistry, 2021) [3]
