The problem of bacteria and bad breath: How to solve it?

By Vitia

Bad breath, or halitosis, is a problem that can affect confidence and personal relationships. It can be caused by various bacteria present in the mouth, which release sulfur compounds responsible for unpleasant odor. Poor oral hygiene or oral health problems can allow these bacteria to proliferate.

Fortunately, there are many ways to combat bad breath and prevent its recurrence. From implementing good oral hygiene habits to incorporating additional practices, such as using natural mouthwashes and a balanced diet, it’s possible to maintain a fresh and healthy mouth.

Taking proactive measures not only improves your breath, but also protects your overall oral health, preventing future complications and ensuring a brighter, more confident smile.

Common symptoms:

  • White tongue : A white or yellowish coating may indicate a buildup of bacteria.
  • Swollen or bleeding gums : This may be a sign of gingivitis, a bacterial infection that worsens if left untreated.
  • Canker sores or ulcers : They indicate an imbalance in the bacterial flora.

Main responsible bacteria:

  • Porphyromonas gingivalis : Causes gum disease.
  • Treponema denticola : Related to periodontitis.
  • Fusobacterium nucleatum : Associated with dental plaque.

Solutions to combat bad breath

  1. Brushing your tongue : Removes the bacterial layer.
  2. Flossing : Helps clean spaces between teeth.
  3. Antibacterial mouthwashes : Prefer those containing chlorhexidine or essential oils.
  4. Regular dental visits : Detect problems early and prevent complications.

Additional tips:

  • Hydration : Keeping your mouth moist helps reduce bacterial growth.
  • Healthy foods : Eating crunchy fruits and vegetables like apples and carrots helps cleanse your mouth.
  • Avoid excessive alcohol and caffeine consumption: Both alcohol and caffeine can cause dry mouth, which promotes the growth of bacteria that cause bad breath. If you consume them, be sure to drink enough water to keep your mouth hydrated.
  • Use homemade mouthwashes with essential oils: Some essential oils, such as tea tree, clove, and eucalyptus, have antimicrobial properties. You can prepare a homemade mouthwash with water and a few drops of these oils to improve oral hygiene and combat bad breath.
  • Chew fresh mint or parsley leaves: Both mint and parsley have natural antibacterial properties and help freshen breath. Chew a few leaves after meals for instant freshness.

Maintain proper oral hygiene and make some changes to your habits to effectively eliminate bad breath!
