Why is maintaining a lip of enamel important during preparation?

Maintaining a lip of enamel during preparation is crucial because it helps to avoid damage to adjacent teeth. When enamel is preserved, it creates a protective barrier that minimizes trauma to neighboring structures. This is particularly important in ensuring that the integrity of adjacent teeth is not compromised during various dental procedures, such as restorations or extractions.

Interestingly, while aesthetic concerns may play a role in dental preparations, the primary focus of maintaining enamel is to safeguard surrounding dental tissues. This preventive approach not only protects the health of adjacent teeth but also facilitates better outcomes in restorative dentistry, as a healthy environment is essential for successful treatment.
