hi there for the past few months i have been suffering from really sensitive teeth to anything. i went to the dentist a few months ago as a fillinf had come out so she put in another filling and gave them a clean and she didnt say i needed any other fillings or anything. since monday night i have been using colgate sensitive toothpaste but so far its not working. im really worried my teeth are going to fall out or something serious is wrong with me. had anyone else suffered from this? any ideas on what could be causing it?

please reply
louise
