Dentinal tubules are microscopic, straw-like tubules containing fluid which run from the pulp outwards through the dentin and end at the junction between the dentin and the underlying surface of the enamel. The dentist should seal these openings prior to placing a filling in order to reduce or eliminate sensitivity. This sealant could be varnish or part of the process of placing a porcelain filling.
