What Is Teeth Whitening?

If you wish you could banish stains and discoloration from your teeth with a minimally invasive, affordable, and quick treatment, then teeth whitening is the perfect cosmetic treatment for you. Some people use over-the-counter whitening products to try to achieve a brighter smile, but these are largely unregulated and not ADA-approved.

Whitening trays are not designed with your specific teeth in mind so they can cause irritation and damage to your soft tissues as well as your teeth. A dental whitening procedure will carefully analyze your teeth and protect your soft tissues before administering ADA-approved whitening products.

These products make your teeth temporarily more porous so the hydrogen peroxide can penetrate below the enamel to remove intrinsic stains. Oxygen molecules in the whitening product react violently with staining molecules and break them apart so your teeth look whiter and stain-free. If you want a whiter smile today, contact us at Foothill Modern Dental to schedule an appointment.

What to expect at your preventive dental care appointment

tooth cleaning icon


Dr. Sarno will perform an oral exam to determine how severe the discoloration is. This will help him develop a customized treatment plan to whiten your teeth. She will also check for signs of oral health problems that may need to be treated for whitening.

(Take Home Only)

Impressions of your teeth will be taken and sent to an outside dental lab. They use your teeth as a model to create customized whitening trays that fit over your teeth. Once these are ready, you’ll return to the office to pick them up.

It’s our priority to keep your gums and teeth healthy and safe. Custom whitening trays prevent whitening products from touching your gums. In the office, we use cheek protractors and protective gel to guard your soft tissues from the whitening gel.

Once preparation is done, Dr. Sarno will apply the whitening product directly to your teeth. By exposing it to a UV light, this activates the whitening properties. This will be rinsed out after an hour. Take-home whitening is applied to the inside of your trays and you will wear the trays each day for up to 2 weeks.

Take-Home Teeth Whitening

If you prefer a lower-concentration whitening treatment because you have sensitive teeth or don’t want a light-activated treatment, then take-home whitening is more suitable for you. It is also more convenient because patients can whiten their teeth from their homes and continue getting things done around the house.

We take impressions of your teeth at the office and these impressions are used by a dental lab to create customized whitening trays for you to wear. Once your trays are ready, you’ll pick them up along with the whitening product and instructions to begin your treatment.

In-Office Teeth Whitening

Have an upcoming event or need to take formal photos? In-office whitening will speed up the whitening process with light-activated whitening agents. The whitening product will be applied to your teeth after protecting your soft tissues with cheek protractors and a protective gel.

Then, a UV light will be exposed to your teeth to speed up the reaction process. After about an hour, this will be rinsed off and you will see the results instantly. Your enamel can be lightened by up to 10 shades in just one session.

How Long Does Teeth Whitening Last?


Teeth whitening can last anywhere from 6 months to 3 years. It ultimately depends on how well you maintain it. You can drink through a straw and rinse your mouth after eating to reduce staining from consumption. Avoid smoking and all tobacco products. Practice good oral hygiene by brushing and flossing regularly and attending dental cleanings every 6 months.

Can Teeth Whitening Cause Sensitivity?

Teeth whitening can cause tooth sensitivity as a side effect but this is only temporary because the whitening agent increases the porosity of your teeth to break down stains. Once your teeth remineralize in 48 hours, the sensitivity will go away. Try using a desensitizing gel or sensitive toothpaste. If your teeth feel sensitive, avoid hot and cold foods and drinks.
