Definition and Overview of Teeth Whitening

Teeth whitening, also known as dental bleaching, is a cosmetic process aimed at lightening the natural color of teeth without removing any of the tooth surfaces. It’s a popular method to combat discoloration caused by various factors, including diet, age, certain medications, and lifestyle habits like smoking.

Types of Teeth Whitening: Professional vs. DIY

There are primarily two types of teeth whitening: professional (in-office) and do-it-yourself (DIY) home treatments. Professional teeth whitening is performed in a dental office under the supervision of a dentist, offering immediate and noticeable results. On the other hand, DIY whitening involves over-the-counter products like whitening strips, gels, and toothpaste, which are less potent and require a more extended period to show results.

Whitening Agents: Hydrogen Peroxide and Carbamide Peroxide

The main active ingredients in most whitening products are hydrogen peroxide and carbamide peroxide. These chemicals help in breaking down stain deposits on the teeth, making them appear whiter. However, the concentration of these agents varies between professional and over-the-counter products, influencing both their effectiveness and potential risks.

Brief Overview of Whitening Methods: Strips, Gels, Toothpaste

Over-the-counter whitening methods include:

  • Whitening Strips: Thin, flexible plastic strips coated with a whitening gel. They are applied to the teeth’s surface and are a convenient, affordable option.
  • Whitening Gels: Clear gels containing peroxide, applied with a small brush directly to the teeth’s surface.
  • Whitening Toothpaste: Contains mild abrasives and chemicals that can remove surface stains. While less effective at bleaching, they are useful for removing superficial stains and maintaining professionally whitened teeth.

The Risks of Teeth Whitening: Tooth Sensitivity

Causes of Sensitivity After Whitening

Tooth sensitivity is one of the most common side effects of teeth whitening. This discomfort is often due to the peroxide in whitening agents, which can penetrate the tooth enamel and irritate the nerve endings. The higher the concentration of peroxide, the greater the risk of sensitivity.
