Teeth Whitening Q&A

What is teeth whitening?

Teeth whitening treatments use special solutions of hydrogen peroxide or carbamide peroxide to penetrate your teeth and remove deep stains. 

While over-the-counter (OTC) treatments, such as whitening toothpastes and strips, can lift extrinsic stains — discoloration on the surface of your teeth — professional whitening lifts intrinsic stains from deep within your teeth for visible results that last.

What causes tooth discoloration?

Tooth discoloration typically takes years to build up, which is why you may not notice yellow stains on your teeth until you’re older. These stains typically accumulate from a combination of factors, such as:


Certain foods and drinks leave yellow or brownish stains on your teeth. Coffee, tea, and red wine are the most well-known culprits, but dark berries, soy sauce, and sugary sodas can also cause tooth discoloration.


The thickness of the hard enamel on the outside of your teeth helps determine how white they’ll be. If you have naturally thin enamel, the darker dentin underneath may show through.


As you age, your enamel naturally begins to thin and erode, exposing the darker dentin underneath.


Many medications, including antihistamines and antibiotics, can leave your teeth looking yellow or brown.


Both cigarettes and chewing tobacco contain tar and nicotine, which can significantly darken the appearance of your teeth.

What happens during teeth whitening?

Zoom in-office teeth whitening takes just 45 minutes. After covering your lips and gums for protection, your dentist applies a whitening solution to your teeth. As the solution penetrates your teeth, your dentist uses a special light to activate the treatment.

Depending on the severity of your discoloration, your provider may repeat this process several times until achieving your desired results.

In-office teeth whitening is the most effective treatment for a dramatically brighter smile. However, Zoom also offers at-home whitening trays to help you attain professional results on your schedule.

Your dentist creates these custom trays by making impressions of your teeth. Each day, you add a small amount of whitening gel to the trays and wear them either for 30 minutes a day for two weeks or overnight until you see the results you want.
