Bleeding gums along and bad breath is due to plaque buildup leading to gingivitis, and if not treatment may lead to periodontal disease.
Next Steps
1) Get teeth cleaning done.
2) Brush twice daily with a soft-bristled toothbrush.
3) Use chlorhex ADS mouthwash twice daily for 10-15 days, unless contraindicated.
Health Tips
If the bleeding persists even after cleaning and all these precautions, or if you notice swollen gums, loose teeth, pus, or pain, visit a dentist asap.
