Meet Dr. MahlerWith Smile312’s on-site digital milling lab, we create and place your custom crown during the same appointment. No waiting weeks. No temporaries. Just precise, same-day results crafted for long-lasting strength and natural beauty.
We start by capturing a highly accurate 3D scan of your tooth using advanced digital imaging technology. This ensures the new crown will fit perfectly and align seamlessly with your bite.
