Teeth Whitening

Cosmetic Dentistry

Teeth whitening is a popular, conservative way to brighten a smile. Options range from professional treatments to over-the-counter products, but they work differently and may not produce the same results for every type of discoloration.

Before whitening

A dental evaluation can help identify the cause of discoloration and determine whether whitening is appropriate. Cavities, gum irritation, existing sensitivity, and other oral-health concerns may need to be addressed first.

Whitening changes the shade of natural teeth only. Crowns, veneers, bonding, fillings, and other tooth-colored restorations will not whiten, which could create a visible difference between them and the surrounding teeth.

Options to consider

• In-office professional whitening, when appropriate
• Dentist-supervised take-home whitening with customized trays
• Over-the-counter whitening strips or gels
• Whitening toothpastes designed primarily to remove surface stains

Understanding your results

Whitening toothpastes mainly remove external surface stains, while peroxide-based whitening products can lighten the shade of natural teeth. Results and treatment times vary depending on the type of staining, the product used, and your individual smile.

Temporary tooth sensitivity or gum irritation can occur during whitening. Your dentist can help you select an appropriate method, explain how to use it correctly, and discuss ways to manage sensitivity.

Whitening results are not permanent. Foods, beverages, tobacco, and normal aging can gradually cause staining to return, so occasional maintenance may be recommended.
