One of my favorite minimally invasive techniques is the “sandwich technique.” When a patient has significant erosion on both the facial and lingual surfaces of a tooth, the tooth often needs complete protection. The traditional solution might be a full-coverage crown but that also means removing even more of the already compromised tooth structure. Whenever possible, I prefer a different approach. By placing a thin porcelain veneer on the facial surface and direct injection-molded composite on the lingual, I essentially sandwich the remaining tooth structure between two restorative materials. The result is a restoration that protects the tooth while preserving as much natural tooth structure as possible. One of the questions I get most often is, “What happens when the composite wears over time?” That’s one of the biggest advantages of this technique. Because it’s injection molded from a preserved design, I have the original template. Years later, if the lingual composite needs refreshing, I can simply resurface and rebuild it without replacing the porcelain or sacrificing additional tooth structure. I’ve used this approach for years with excellent long-term predictability. Minimally invasive dentistry isn’t about doing less, it’s about doing only what’s necessary to help teeth last a lifetime.
