I;ve had this bad terrible body odor that for years and it won't go away, and it's been really disturbing the people I wouk with and the customers at my job I keep washing and showering but for some reason every time people walk near me they seem to turn their nose up at me and I always hear someone from a distance say you stink, I also have cavities that need filling the rotten stuff inside my tooth really smells bad so my breath and my body stinks which bring me to my question, does having cavities in your teeth rotten smelly cavities make your body smell just like the rotten cavitiy??

Sounds possible. The teeth are probably infected and that's not a good thing either. You really should get them taken care of before it becomes a health issue.

The rotten teeth aren't directly related to body odor, but you probably have a chronic infection in your teeth and gums that has lowered your resistance to bacteria all over your body. It's similar to really smelly feet, only in all your moist areas that perspire. You can even have fungus as well as bacterial infection. You may find that dental work followed by antibiotics and weeks of careful bathing will help, but it isn't as easy as just taking antibiotics and applying anti-fungal lotions. So see a dentist or dental school, and then see a doctor about 2 weeks later if it hasn't cleared with antibiotics + antifungal remedies you can buy in a drugstore.
