Cavity problem
I (19 F) have had issues with cavities my whole life. When I was younger I will admit I hated brushing my teeth so did skip once or twice a week but when I turned sixteen I was sick of always going to the dentist and being told I have cavities, so then I really started to try and lock in. However every year I have at least nine cavities, all early stages but still. I have to get them filled and almost all my teeth have fillings in them now. This past year my routine has been extremely thorough, brushing 2-3 times a day with the expensive toothpaste my dentist told me to get, I use a water pick twice a day and floss with regular floss with toothpaste on it twice a day. I use mouthwash in the mornings. I’ve been cutting back on sugar and never have any sugary drinks. However I am now developing a sensitivity in one of my teeth to cold and sweets. I believe it’s a cavity. I just don’t understand, every year I have the same amount of cavities or old fillings need to be re done and the dentist says that I should brush my teeth more but I do! I don’t get plaque build up anymore and now I’m just so lost on what to do and I’m so frustrated. I do so much more than the average person but haven’t ever had less than four cavities when I go to the dentist. Does anyone have any recommendations for what I should do?
