Hello. I have a polyp in my nose which makes me breathe out my mouth most of the time, which is causing mouth dryness and bad breath. I try to drink water but my mouth gets dry super quick. I will get my polyp surgically removed soon, but not yet. When my polyp’s removed will the bad breath go away? Also I have a post nasal drip and just wondering, will chewing gum mask the smell of bad breath and post nasal drip, so will you be able to smell it while chewing gum. I use a tongue scraper but that doesn’t help much as the bacteria quickly breeds again after a while. Also, about braces, I have baby teeth, but my adult teeth are awfully crooked. I’m 13. Can I have braces with my baby teeth in my mouth?
