Multiple Teeth Isolation Method

This is much more time-consuming than single tooth isolation, and so is only used when it is required for endodontics.

1. Multiple holes are punched for the relevant teeth. The positions can be marked on the dam using a ball-point pen.

2. A clamp is selected for the most posterior tooth in the arch.

3. The rubber dam is again fitted with the frame and clamp.

4. Using forceps, the clamp is positioned and successive teeth are isolated by stretching and forcing the dam between the interproximal contacts. A second clamp or strip of rubber can be used to retain the dam anteriorly .

5. Placing rubber dam through tight interproximal contacts can be difficult. Stretching the dam will make it thinner, and makes ‘knifing’ it through a tight contact easier. Waxed dental floss can also be used to ease dam through a difficult contact. It can then be tied off to help retain the rubber.
