How Does Dental Bleaching Work?

Teeth whitening also known as dental bleaching is a popular cosmetic dental procedure that aims to lighten the color of your teeth. This procedure can enhance the appearance of your smile and boost your confidence. But how exactly does dental bleaching work?

The Role of Tooth Enamel

Before we dive into the specifics of dental bleaching it is important to understand the structure of your teeth. The outer layer of your teeth is called enamel which is a hard mineralized substance that protects the inner layers of your teeth. Over time your enamel can become stained or discolored due to various factors such as –

Consuming dark colored foods and drinks like coffee tea and red wine
Smoking or using tobacco products
Poor oral hygiene habits

The Process of Dental Bleaching

Dental bleaching works by using a bleaching agent usually hydrogen peroxide or carbamide peroxide to break down stains on your teeth. The bleaching agent penetrates the enamel and reaches the dentin the inner layer of your teeth where it oxidizes and breaks down the stain molecules. This process results in a whiter brighter smile.

There are two main methods of dental bleaching –

In office bleaching – This method involves a dentist applying a high concentration bleaching gel directly to your teeth. A special light or laser may be used to enhance the bleaching process. In office bleaching typically yields immediate results and can lighten your teeth by several shades in just one session.
At home bleaching – With this method your dentist will provide you with custom made trays and a lower concentration bleaching gel to use at home. You will need to wear the trays for a specified amount of time each day for a few weeks to achieve the desired results.
