Bonding Boise Dentist Bonding is the application of tooth-colored composite resin to enhance the appearance of your smile.

Then the composite resin will be applied and sculpted over your tooth. After the resin has been applied, an LED light is used to harden the resin. It will then be polished. Results are achieved immediately and can subtly or drastically change the appearance of your smile. Bonding is a safe, affordable and aesthetically pleasing solution for many dental problems.
