I have a semi-hard, movable, non-irritated little bump in the soft-tissue of my lower gum that is probably half the size of an eraser at the end of a pencil, and at a dental check up today I asked the hygienist about it. She said ya, definitely feel that, let's ask teh dentist when she comes in. The dentist took one feel around and said 'probably a blocked salivary duct', I asked if there was any reason to keep an eye on it or be concerned, and she said 'nope, come back in 6 months for a cleaning and we'll look at it." There is no nasty ulceration, no hard immobile mass, but I'm convinced its some malignancy and the dentist was being dismissive. Am I nuts? Should I get a second opinion? This made me feel like it was at least okay to deal with after the holidays, but I have a feeling anxiety is going to get the best of me here and convince me its something more than what the dentist explained.
