Peroxide and Teeth: How It Works & Benefits

Whitening

Peroxide oxidizes chromogens (color compounds), breaking them into smaller colorless molecules that wash away.

Antibacterial

Kills cavity/gum disease bacteria; in toothpaste/mouthwash promotes oral health.

Risks

  • Enamel erosion: Overuse/high concentration wears enamel, increasing cavity risk and sensitivity.
  • Tooth sensitivity: Usually temporary; if persistent, see a dentist.

Bottom Line

Peroxide whitens effectively and fights bacteria, but use in moderation per label instructions. Consult your dentist with concerns.
