Teeth whitening

Teeth whitening, often referred to as dental bleaching, is a popular cosmetic dental procedure aimed at lightening the natural color of teeth without removing any of the tooth surface. It does not completely change the color, but rather lightens the existing shade.

History

• The desire for whiter teeth dates back to ancient times. Early civilizations used a variety of methods and substances like vinegar and ground pumice stone to whiten their teeth.
• Modern teeth whitening procedures began to evolve in the late 20th century, with the introduction of hydrogen peroxide solutions.

Types of Teeth Whitening

• In-Office whitening: Performed by dental professionals using high-concentration bleaching gels.
• At-Home whitening: Products available for home use, which typically require longer treatment times.
• Whitening toothpastes: Contain abrasives and chemicals that remove surface stains.
• Natural whitening methods: Such as using baking soda or activated charcoal.

Causes of Tooth Discoloration

• Food and Drink: Coffee, tea, red wine, and certain fruits can stain teeth.
• Tobacco use: Smoking or chewing tobacco can cause teeth to yellow.
• Aging: Dentin naturally yellows over time.
• Medications: Certain medications, like tetracycline, can cause tooth darkening.
• Trauma: Injuries can result in a change in tooth color due to enamel damage.

Risks and Side Effects

• Tooth sensitivity: One of the most common side effects, often temporary.
• Gum irritation: Can result from whitening products getting on the gums.
• Overuse of whiteners can damage tooth enamel or gums.

Cost and Accessibility

Teeth whitening costs vary depending on the type of treatment chosen and geographical location. In-office treatments are generally more expensive than at-home methods. Many dental insurance plans do not cover cosmetic procedures, including teeth whitening.
