If a tooth develops an infection due to dental trauma or tooth decay, the tooth's nerve (or pulp) may die leaving the tooth susceptible to the forming of an abscess. The central canals inside the tooth are cleaned out and completely filled with an inert, soft filling material to seal the end part of the root. A permanent filling or crown is then placed on top. By doing this the tooth can remain in the mouth for many years to come. The procedure can take a few visits to complete and molar (back) teeth have more complicated root canals, so they take longer. During these visits a frame of rubber sheeting called a rubber dam is placed around the tooth to isolate if from saliva.Our new piece of equipment,The Reciproc, can make negotiating the cleaning instruments into fine canals easier. Both Lauren and Martin have attended the specialised training course in this equipment and can explain its use if you want to know more.
