Short Description
A technique using mild acid to roughen tooth enamel, improving the bond for fillings or sealants.
Long Description
Acid etching is a dental technique that involves applying a mild acidic solution, usually phosphoric acid, to the surface of a tooth. This roughens the enamel or dentin microscopically, creating a stronger surface for dental materials to adhere to.
It’s commonly used before placing composite fillings, sealants, or bonding materials. The acid is applied for a few seconds, then rinsed off and dried before the restorative material is added.
This process improves the retention and longevity of dental restorations by enhancing the mechanical grip between the tooth and the material, reducing the risk of failure or detachment.
