One of the most challenging types of “simple dentistry” is to accomplish a direct resin restoration (aka, white filling) that looks good, functions well, and seals out bacteria from re-entering the side of the tooth. Only a few years , which had been somewhat sensitive since being placed. An X-ray of the area shows where the fillings left a small gap at the margin between the tooth and the filling material – the most likely cause for her sensitivity.
When we replaced the restorations, we used a different approach: isolating the teeth from the saliva by use of a rubber dam. This thin, flexible sheet of rubber secures the teeth and prevents the tongue, gum, and saliva from interfering with the shape or fit of the new fillings. The new X-ray shows a more predictable outcome by use of this technique; the patient’s sensitivity is now resolved.
