[|Human|] Hello I have two porcelain crowns on my front teeth which were placed on in jan 2007 one had to be replaced in 2011 because it cracked the remaining one was fine until nov 2013 I began having tightness in the tooth when I lay down either on my back or sides and when i wake up the tooth takes 2 hours to adjust to a normal feel it sort of pops back into place and i hear it popping  It seems as when im sitting up and position my head to the side the tooth moves.  I have some sensitivity in the tooth and noticed a small bump on the gumline in nov 2013 that used to hurt to the touch for 2 weeks then the pain disappeared but i still have the bump but no pain when i touch it.  Several dentists have stated "it doesnt look like an absess" or "i dont see any inflamation"....can u help?  right now the symptons are mild and more of a discomfort but paranoid it will blossom into something serious if i dont take care of it now
[|AI|]  Hello, thank you for consulting with Chat Doctor. As you are mentioning that you first experienced pressure in the tooth while lying down it proves that there was some infection started in the tooth. And when you noticed some swelling on the gums the infection should have been turned into pus and spread to the apical region. The dentist must not have noticed it as in the starting, x-ray does not show any changes. You should visit your dentist and get the crown removed with root canal treatment of the tooth. Hope it will help you.
