I have a friend who is always around smokers and every time I talk to him his breath reeks of cigarette smoke! He swears he never smokes and his hair/clothes never smell, but the scent on his breath is so strong. Is it really just secondhand smoke?

Oraltech Labs Has suggested I have my tonsils remove to prevent bad breath caused by tonsil stones. Will this cure my bad breath?

So Im having this mouth ulcer which is located on my mouth cheek and I noticed that Im also having a bad breath, I never had this bad breath before, so could the mouth ulcer be causing this? and how do I heal it fast? I use salt and water to gargle it, I use a teaspoon of salt and a small cup of warm-cold water then I gargle it for around 15 to 20 seconds.
Yeah u only answer my 2nd 1uestion, how about my 1st question, can it cause bad breath?

I would prefer not to have chronic bad breath after I eat, since I am going there with a guy I like. If there is anything garlic free that would be great.

Yes, I do eat, use dental floss, brush my teeth and use mouthwash, but my breath still smells bad. I even used the mouthwash that kills germs that cause bad breath!

Im just wondering, does it make your breath smell bad or what? Im just curious. Im talking about cigarettes.
I know it causes bad breath, but i mean even if you brush your teeth.. i feel like my breath stinks way more now.

I have very bad breath, am in my 30s, weight proportionate vegetarian female with no health issues and normal digestion but my breath has been extremely awful for years. My mouth is full of metal fillings which in the future I want to switch to white fillings. In the past few weeks I had 5 fillings for cavities. I also got my teeth and gums cleaned. Would getting the fillings help improve my breath?

Please help me I am 16! I dont know whats wrong with me and i dont know how to bring it up with my family so i can go to a doctor!
