The ____ is used to create holes in the dental dam that are required to expose the teeth for isolation.

  1. Dental dam frame

  2. Dental dam punch

  3. Dental drill

  4. Dental mirror

The correct answer is: Dental dam punch

A dental dam frame is used to hold the dental dam in place. A dental drill is used for procedures involving the teeth themselves, not necessarily for placing the dental dam. A dental mirror is used for visualizing the teeth and surrounding structures, not for manipulating the dental dam. A dental dam punch is specifically designed for creating holes in the dental dam, making it the correct answer.
