Can You Inherit Bad Breath?
Now, the other sort of condition is let's say that your mother and grandmother has bad breath and you want to know, will I inherit bad breath? That possibly could happen because you do inherit-- let's say the shape of your tongue, just as you inherit eye color or ear shape. Your tongue sometimes will tell you if you have bad breath or not. There's a condition called fissured tongue or the papilla-- the fibers that make up your tongue-- are an inherited trait and you may trap more bacteria.
So if your mother or grandmother tends to have bad breath and they do keep a clean mouth, but yet they still have bad breath, you may be prone to have bad breath if you have similar tongues.
