Pretty much what Gellia said, a visit to a dentist should help you resolve this issue. It can be anything from plaque/tartar/calculus located beneath your gums, to cells collected on your tongue, to an abscess.
Hi, I had a similar problem 2 years ago. And a dental cleaning helped me.
Hi Taylor,
I recently had the same thing happen to me. Did you ever find out what caused this?

Hi,
It's a good possibility that the smell comes from plaque forming below the gumline where your brush and floss won't reach. A simple trip to the dentist for a thorough cleaning will probably help.
There's not much you can do yourself until you have a dental evaluation. Please make an appt with your dentist.
Hope this helps.
Best to you,
Gellia
