Funky breath might sometimes be an indication. Have acid reflux? Your breath might be severely damaged by the buildup of stomach acid throughout the night.
And those deep pockets may turn into breeding grounds for some very foul conditions if your gums aren’t pleased (we’re talking about periodontal disease).
The good news is that foul breath is not a permanent condition. Show that tongue coating who is in charge by grabbing a tongue scraper or turning your toothbrush over.
