What makes a smoke detector work?
A rubber dam is square sheet of thin rubber used to isolate the tooth receiving treatment. They will punch a few holes in it and push the dam around the tooth (and a couple adjacent teeth). It's a way to keep the tooth dry and uncontaminated by the bacteria in your mouth. It produces the best results and is nothing to worry about. Hope that helps.
did u drop the remote? that's all i can think of. oh, wait a minute, check the vehical's battery too. that happened to my aunts Jeep and she changed the truck battery and it was fine.
