Hi! I'm not really a mouthwash person I used to use mouthwash maybe once a week or rarely. But after a recent dental visit due to toothache I started to be conscious of my teeth. My dentist told me that I almost lost one of my front teeth because of a cavity that affected the pulp or nerves. That scared me so since then I decided to use mouthwash daily and almost twice a day, flossed, and brushed longer. After 2 weeks my teeth became sensitive. Of course with hot and cold stuff. But one tooth becomes sensitive with just a touch of a lukewarm water. I could not even swish it longer with water now, always in pain when swishing after brushing. During that visit the dentist assured me that I don't have any cavities left or nothing to worry at all but why is this happening now maybe she missed something? I don't know. I don't really have time now to make another visit. I thought that the mouthwash may have caused it because I used it a lot and used a product that is really strong and contains alcohol. Can a mouthwash makes enamel and dentin thinner that may have caused a sensitive tooth? Hope someone could help!
