Teeth Whitening

Teeth whitening, also known as bleaching, is a non-invasive procedure designed to whiten and brighten teeth that are stained, discolored, darkened, or yellowed. Since its introduction in the 1980s, the popularity of teeth whitening products and procedures has skyrocketed. According to the American Academy of Cosmetic Dentistry, the most common response to “What would you like to improve most about your smile?” was: whiter and brighter teeth.

Why Do Teeth Become Discolored?

The whiteness of a tooth depends on how light reflects and scatters off the enamel, the tooth’s outermost layer. Teeth can look dark or discolored due to:

• External Stains: Caused by certain foods, beverages, and tobacco.
• Internal Discoloration: Due to hereditary factors, certain medications, tooth decay, restorations, or trauma.
• Aging: As enamel thins over time, the underlying yellow dentin becomes more visible.

Advantages of Professional Teeth Whitening:

Although over-the-counter teeth whitening systems are popular, they come with health concerns and limitations. Professional teeth whitening performed by a dentist offers several advantages:

• Prescription-strength bleaching agents ensure effective and dramatic results.
• Teeth and gums are carefully protected during the procedure to avoid damage.
• A dentist can address contraindications such as sensitive teeth, cavities, or gum disease before treatment.
• Custom treatment plans consider existing dental restorations, which do not whiten.

Teeth Whitening Options:

• In-Office Whitening: A prescription-strength procedure performed in a dental office. In as little as one hour, teeth can be whitened by several shades. This is the safest and most effective method, with sensitive areas and surrounding tissues carefully protected.
• Take-Home Whitening Systems: Custom-fitted trays provided by the dentist allow bleaching agents to stay in maximum contact with teeth while protecting other areas of the mouth. Results are achieved over a longer period compared to in-office treatments. Take-home systems can also be used as a follow-up to maintain or perfect in-office results.

In general, individuals with yellow tones in their teeth respond best to whitening procedures, while brown or grayish hues may require more extensive treatment or alternative cosmetic solutions. Teeth whitening may not be recommended for those with sensitive teeth, worn enamel, or significant gum disease.
