Hi, I was just wondering if anyone can help me. I suffer with a lot of acid reflux due to a small hiatus hernia. The acid often enters my mouth, and as of late, my teeth have become extremely sensitive, and a slight yellowish colour. I'm only 18, and I have fairly healthy teeth otherwise, and do brush my teeth morning and night. I had the habit of brushing my teeth after the acid reflux to get rid of the foul taste, but my dentist advised me not to do so, as this would just scrub the acid into my teeth. I was wondering if there was any sort of mouthwash or gentle toothpast you could reccomend that will help with my extremely sensitive teeth, and yellowish tinge to my teeth. I can't seem to find any that have worked, or do both. Thanks.
