Over the past year or 2 years so i’ve deveopped quite an odd obsession, and that’s breath. More particularly the smell of breath, let me explain. I’ve always been obsessed with having fresh breath, i avoid any foods with garlic or onion or anything that can cause bad odour, i brush my teeth 3 times a day atleast and floss after i eat anything. I also keep a pack of gum on me at all times. But sometimes i feel like I still have bad breath, but if i ask my friend will tell me it’s fine (this is a friend who does not care and would not lie to make my feelings better). I’ve asked my doctor and he says my oral hygiene is above average and i’m healthy orally. I read online that some people can hallucinate smells almost like they would hear voices or see things, so my question is, has a doctor ever seen a patient like this? Or is it not a hallucination and should I be checking for something deeper to know the root of the issue. Sorry if this sounds quite odd but i could not find much online and just wanted to hear some opinions
