Tooth bleaching, also known as teeth whitening, is a cosmetic dental procedure that uses bleach or other chemicals to lighten the color of the teeth. The bleach works by breaking down the staining molecules on the teeth, which results in a brighter, whiter smile.

The length of time it takes to bleach teeth depends on the method used and the severity of the staining. In-office teeth whitening treatments typically take about an hour, while at-home treatments may take several weeks to achieve the desired results.

Tooth bleaching is generally considered safe when performed by a dental professional. However, some patients may experience temporary side effects such as tooth sensitivity, gum irritation, or discomfort. It is important to follow the instructions provided by the dental professional and to use only products that have been approved by the American Dental Association (ADA).

The results of tooth bleaching are not permanent, and they can vary depending on the individual patient’s oral hygiene habits and lifestyle. With proper care and maintenance, the results of tooth bleaching can last up to two years. However, patients who smoke or consume staining foods and beverages may notice the effects fading more quickly.
