Morning breath is common because saliva production naturally decreases while you sleep.
Saliva helps wash away food particles and control oral bacteria. When saliva flow decreases overnight, bacteria can produce odorous compounds more easily.
Sleeping with your mouth open, dehydration, smoking, certain medications, and poor oral hygiene can make morning breath more noticeable.
Brushing before bed, cleaning between your teeth, and cleaning your tongue can help reduce the bacteria and debris present overnight.
Drinking adequate water throughout the day may also help.
However, persistent bad breath that continues during the day can sometimes be associated with gum disease, cavities, dry mouth, or other dental and medical conditions.
If bad breath remains a concern despite good home care, have your oral health assessed.
Port Moody Smile Dental can help identify potential dental causes of persistent bad breath and recommend appropriate preventive care.
