Why is a rubber dam so essential?
The rubber dam is a thin sheet of latex that isolates your tooth and is very important for two main reasons. First of all, it ensures a sterile area where the tooth is treated and therefore prevents infection by oral bacteria that may not be present in the canal already. Second of all, endodontists work with tiny files that can fall in your throat and go further. To recover one of those would mean to undergo a surgical procedure, otherwise totally unnecessary.
