Teeth whitening is a cosmetic procedure that brightens teeth and helps to remove stains from the enamel and dentin. The enamel is the outer layer of a tooth, and dentin is the inner layer. The enamel is porous, so when we eat foods that stain, like red wine, coffee, and berries, the particles from these substances can sink into the enamel. The dentin is deeper, so stains can’t reach it.

The bleaching agent lifts stains from the enamel and dentin, making teeth brighter. This is accomplished either by a bleaching agent.

Teeth Whitening Options

Your dentist can help you explore options for whitening your smile, including in-office bleaching and take-home whitening kits.

In-office bleaching, also known as chairside bleaching, uses hydrogen peroxide or carbamide peroxide to lighten teeth. An oral healthcare professional applies the whitening solution to your teeth and may also use ultraviolet light or heat to speed up the process.

Take-home whitening kits, on the other hand, use custom-made clear plastic trays and whitening gel. The trays are designed to fit your teeth precisely, which allows whitening gel to evenly coat all surfaces of your teeth. The at-home whitening kits are worn for a certain amount of time every day for one to two weeks.

Advantages of Teeth Whitening

There are several benefits to teeth whitening. Here are just a few:

1. Whiter teeth give a more youthful appearance.

2. Whiter teeth boost self-esteem.

3. Whiter teeth add confidence to your smile.

4. Whiter teeth give you a more comfortable feel.

Candidacy for Teeth Whitening

If you’re interested in whitening your teeth, it’s best to consult with your dentist beforehand. You’ll want to make sure you’re a candidate for the procedure, and that the process is safe for you. Generally, teeth whitening is safe, but there are some exceptions. For example, pregnant or breastfeeding women should let the process wait until after delivery.

Additionally, people who have sensitive teeth might want to avoid the procedure. It’s also not recommended for those with untreated cavities.


Your teeth often become discolored because of their porous nature. Certain dark foods and drinks, such as cola, coffee, and berries can stain the teeth. Smoking can also stain your teeth, as can certain medications. Teeth whitening is the best solution to get rid of these stains.
