Composite bonds to tooth via

Explanation:
Composite bonds to tooth through both the adhesive layer and resin tags. When the tooth surface—especially dentin or enamel—is etched, it creates micropores that the adhesive resin can flow into. After curing, these infiltrated areas form resin tags, which provide micromechanical interlocking that helps lock the composite to the tooth. At the same time, the adhesive creates a chemical or functional bond with the tooth surface, producing a continuous hybrid layer that further strengthens the bond. Together, the adhesive and the resin tags give a combination of chemical bonding and mechanical interlocking, making this the best description of how the bond is established.
