Overview

Occasional bad breath is common, but persistent bad breath often points to plaque buildup, gum inflammation, dry mouth, tobacco use, or an untreated cavity. The goal is to identify the cause instead of masking the smell with mints.

Key Takeaways

  • A coated tongue, bleeding gums, and food trapped between teeth are frequent causes.
  • Dry mouth can make bad breath worse because saliva normally helps clean the mouth.
  • Gutkha, pan masala, smoking, and alcohol increase bad breath and oral cancer risk.
  • Persistent bad breath with loose teeth or gum swelling needs a dental evaluation.

What You Can Do At Home

  • 1Brush twice daily with fluoride toothpaste and clean between teeth once a day.
  • 2Clean the tongue gently with a tongue cleaner or toothbrush.
  • 3Drink water frequently, especially if you take medicines that dry the mouth.
  • 4Avoid tobacco and limit alcohol-based mouthwashes if they irritate your mouth.

When To Book A Dentist

  • !Bad breath continues for more than two weeks despite good hygiene.
  • !You notice bleeding gums, gum recession, pus, or loose teeth.
