OK My husband and I have just come back from the dentist for our yearly checkup. Prior to our last appointment we hadn't been to the dentist for years. On our last appointment a year ago we were told that our teeth were fine and needed no work at all. We go this year and hubbie is told he needs three of his fillings re-doing and I'm told I need 4 new fillings. We hve not treated our teeth any different in the last year and in fact we've been using an expensive brand of mouthwash for the last 6 months. Now I'm not a dentist but I smell a fish and it ain't the cat food!!
