Teeth whitening sessions typically last about an hour, although the exact time can vary depending on individual needs and the technology used. Advances in whitening technology may allow some sessions to be completed in as little as 45 minutes.

The dentist will review the available shades with you to help decide on your desired outcome. They may provide guidance on what is safe and appropriate based on your current tooth shade.

A professional-grade gel containing hydrogen peroxide is applied to your teeth. This gel penetrates below the surface of the tooth to lighten its color. Professional-grade products are designed to be safe when used under the supervision of a dentist.

Some professional gels also include potassium nitrate, which may help reduce tooth sensitivity and support enamel during the whitening process.

The dentist applies the gel to your teeth and uses a specialized light to activate the whitening agents. Results are typically noticeable immediately after the session.

You may experience temporary tooth sensitivity following the procedure. The dentist may advise avoiding pigmented foods and beverages, such as coffee, red wine, and tomato-based products, for 48 hours to help maintain the results.
