Not sure?: If a tooth has a "cavity", ie, tooth decay, then the decay needs to be removed and a filling placed. There are instances when the top layer of the tooth; the enamel has begun to demineralize, which is the first stage of a future cavity. As long as it is in the surface enamel, it has a chance with proper care and Fluoride to remineralize and not become a cavity. You don't "watch" a cavity get worse.
