Detailed Treatment & Solutions
1ORAL HYGIENE
Brush teeth for 2 minutes twice daily. Floss daily. Replace toothbrush every 3-4 months. Consider electric toothbrush.
2TONGUE CLEANING
Most bad breath bacteria live on the tongue. Use a tongue scraper or brush your tongue. Focus on the back of the tongue.
3MOUTHWASH
Use antibacterial mouthwash. Look for products with chlorhexidine or cetylpyridinium chloride. Don't rely on mouthwash alone - it's a supplement to brushing and flossing.
4HYDRATION
Drink plenty of water. Dry mouth promotes bacterial growth. Chew sugar-free gum to stimulate saliva. Avoid alcohol-based mouthwash which can dry mouth.
5DIETARY CHANGES
Avoid strong-smelling foods before social events. Crunchy fruits and vegetables help clean teeth. Probiotic yogurt may reduce odor-causing bacteria.
6DENTAL CARE
See dentist regularly for cleanings. Treat gum disease and cavities promptly. Clean dentures or retainers properly. Address any dental issues.

Frequently Asked Questions
QCan stomach problems cause bad breath?
Yes, GERD (acid reflux) can cause bad breath. However, this is less common than oral causes. If you have GERD symptoms along with bad breath, treating the reflux may help.
QWhy is my breath worse in the morning?
During sleep, saliva production decreases. Saliva normally washes away bacteria and food particles. Less saliva means bacteria multiply, causing "morning breath." Brushing teeth and tongue and drinking water after waking helps.
