could be tonsil stones....those things smell like shit

Bad breath can make you one break you. Advise to carry mouthwash around. May need to get his mouth checked

KINDLY A MANNER???? FFS, if it's a problem just say SOMETIMES YOU HAVE NOTICEABLY BAD BREATH. ARE YOU AWARE OF THIS??? IF NOT, TRY DENTAL FLOSS. It is UNKIND of you to not have just said so, long ago!!

Gum disease and tooth decay can have a serious impact on heart health! According to both the AMA & ADA. Plus just think how close that infected/not right area is to the brain!
Definitely insist on a checkup from both a dentist & a doctor unless he iseating a lot of garlic and/or onions! (Which even brushing & mouthwash should cure!)

You definitely want to keep it low key and just be honest. I have the same issue with my own father. For years family and friends have made hints to him and he refuses to go to the dentist due to bad experiences. So he occasionally uses a breath freshening spray. I guess he's trying, but most times, I just have to keep my distance in order not to gag.

Either this tip doesn't work or I definately do not have a breath issue.

Try this at home..right now..

Lick the back of your hand..a moment later smell your hand...if you have bad breath you will then be able to smell it ...

Tell them privately, and gently. It could be the result of a medical issue, or brought on by medication. They may be aware of it and unable to do anything about it. Dental work is usually quite expensive, and hardly ever covered by most insurance. Or they could be unaware of it entirely, and a little knowledge is helpful. Not all bad breath situations belie poor oral hygiene.

I'd wait until they were off guard and then we'd hold them down and then waterboard them with Listerine. Fun AND effective!

Tell them. I would want to be told so I can do something about it.

There is no polite way. Either you are a true friend and tell them because they need to know. If they are a true friend as well then they will take it the right way and have whatever the issue might be fixed.... If everything happens that way then full circle, life goes on

would you tell your friend about a nasty mold (which could be cancerous)? Do it and tell him it's about your concern about their health.

If it was me I would very much like to know. It would be initially mortifying..but if nobody tells you how can you know?

A friend of mine that I like/dislike has some horrible breath on occasion. He knows and has taken steps to resolve, so I just hold my breath at times and let him talk to people.

Oh I would definitely say something...I was kindly told that my breath was really bad and found out that I had a curable stomach condition...I never would have known because you really can't smell your own breath...not only did my breath get better, it can prevent me from getting stomach cancer, so do it!

Yes,there is a link between teeth and gum problems with heart disease, politely suggest a Dentist visit,followed by a Doctors visit,to stop something before it gets out of control.
