Almost everyone wakes up with less-than-fresh breath. During sleep, saliva flow drops, your mouth dries a bit, and bacteria build up. This “morning breath” usually improves after brushing, rinsing and a glass of water. On its own, it’s considered normal.
It becomes more concerning when bad breath lingers well into the day, returns quickly after brushing, or is repeatedly mentioned by close family members. Persistent bad breath is often linked to gum disease, plaque buildup on the tongue, dry mouth or untreated cavities.
If your gums bleed easily when brushing or flossing, look swollen, or have a dull red colour, that’s a sign they need attention. Food trapped between teeth, especially in tight or crooked areas, can also cause strong odours.
Good daily care helps: brushing twice a day, cleaning between teeth and gently brushing or scraping the tongue’s surface. Drinking enough water and cutting back on smoking, very strong-smelling foods, and constant snacking also make a difference.
If bad breath continues despite good habits, see your dentist. Sometimes, throat, sinus or stomach issues play a role and need medical input too.
