Most patients who are in need of a dental crown for a permanent tooth qualify for CEREC treatment. The primary difference between CEREC crowns and traditional crowns is that they are made in a single-visit. This makes CEREC treatment ideal for many of our busy or anxious patients who prefer to avoid multiple visits and procedures. In addition to working well for patients who need a crown, CEREC technology is also advantageous for replacing old restorations like crowns and fillings that have degraded over time.
