-- Posted by Anonymous at 1:35 pm on Aug. 15, 2008 I'm 17 and have to have 2 fillings soon, i already have two and I really don't want anymore. I brush 2 - 3 times a day for 2 minutes so I wonder why I keep needing fillings. I'm trying to give up sweets/chocolate as I thought they trigure cavaties causing my teeth to hurt but they still ache whatever I eat It could also be the possibility that because I have antibiotics they make my teeth weak which I heard can happen...I try to have as much protein as poss and I take suppliments so.. am I screwed? (oh & I have just changed from a manual brush to an electrical, dunno if that will help-- which is better in your opinion?) thanks -- Posted by raza301 at 1:45 pm on Aug. 15, 2008 maybe you need to change your brushing techniques
