Why do we invert rubber dams?

To prevent moisture contamination
To provide better vision
To provide a better seal around the tooth
To facilitate easier instrument access

The correct answer is: To provide a better seal around the tooth

Inverting a rubber dam involves stretching the rubber material inwards towards the tooth, creating a snug fit and sealing off the tooth from moisture and other contaminants. This is important for maintaining a clean and dry environment for dental procedures. Option A, preventing moisture contamination, is not the main purpose of inverting rubber dams, as this can also be achieved by properly placing the dam on the tooth. Option B, providing better vision, is not directly related to the function of a rubber dam, as its main purpose is to isolate and protect the tooth being worked on. Option D, facilitating easier instrument access, is also not the primary reason for inverting a rubber dam, as this can be achieved by making small holes in the dam or through other techniques.
