It creates a small \u201ctunnel\u201d access from the biting surface into the area of decay near the contact point. It is most commonly discussed for back teeth (premolars and molars) with early or moderate proximal caries. The goal is to repair decay while preserving the marginal ridge (the tooth structure at the edge of the chewing surface)."}
