How long will Bonding last?
Because bonding material can chip, it is important to avoid such habits as biting fingernails; chewing on pens, ice or other hard food objects; or using your bonded teeth as an opener. The lifespan of bonding materials depends on how much bonding was done and your oral habits. Typically, however, bonding material lasts from 3 years up to about 10 years before needing to be touched up or replaced.
