Although professional teeth whitening treatment by dentists (in-office bleaching) is one great way to go, over-the-counter (OTC) products are the closest way to whiten teeth effectively. OTC teeth whitening products take many forms and present as satisfying whitening results depending on stains. They are cost-effective teeth whitening alternatives, which have gained popularity.

What are teeth whitening strips and how do they work?

Teeth whitening strips are simplest and widely used at-home option to whiten teeth and brighten up your smile.

Strips are thin plastic sheets covered by whitening gel which stick to the surface of your teeth. The whitening gel is made with hydrogen peroxide or carbamide peroxide, the same agents used by dentists but in lower concentration to whiten teeth. The hydrogen or carbamide peroxide work by oxidizing mechanism to remove stain on your teeth. It means that first they break down your teeth discoloration and then produce oxygen molecule, which is the bleaching molecule, to dissolve the stain.

There are natural whitening strips for those people avoiding chemicals. Rather than peroxide, these strips use natural and plant-derived ingredients such as essential oils and botanical whitening agents.

How do you use teeth whitening strips?

Each set of teeth whitening strips comes with a number of strips for both top and bottom row of teeth. You need to peel each strip and gently press until it grips firmly on teeth. Depending on the brand, you may need to leave the strips on your teeth for a recommended period of time. Usually, the strips should be left on for 30 minutes.

This allows for longer contact between the whitening gel and the enamel (outer layer of teeth), which removes discolorations and whiten up teeth. Some people may see significant results even after just one week, but the period usually extends to two or three weeks by repeated application of whitening strips during this time scale.

Follow the instructions for each product to achieve desired whitening results for your teeth.

Are whitening strips safe?

As long as you keep to recommended use, you will have no problems. Teeth sensitivity is a common temporary side effect. It occurs because of exposed underlying layer of teeth, called dentin. Teeth sensitivity is mild and goes away once you stop using the product.

Peroxide-based whitening products work by dissolving the satins through oxidization and do not damage enamel when properly used. Therefore, if used correctly, hydrogen peroxide or carbamide peroxide are safe to use and have not shown to be a risk for enamel.

Keep in mind that hydrogen peroxide and carbamide peroxide make up the main bleaching agents in professional teeth whitening by dentists. Dentists, but, use higher dosage of peroxide to whiten teeth, which increases the chance of sensitivity in teeth.

One issue with hydrogen peroxide is gum irritation and it happens when the whitening gel is exposed to soft tissues like your gums during treatment. You can prevent the gel from coming into contact with gums if you apply the strips based on the product’s instruction. The gum irritation happens because peroxide is also an antiseptic to treat gum diseases and prevent bacterial activity.

Other teeth whitening options vs teeth whitening strips

In-office professional teeth whitening

It is done by dentists in one or more sessions. The session can take 30 minutes to 1 hour. Depending on whether you have superficial stains or deep stains (e,g tetracycline stains), you may require more or less in-office treatments. Also, your dentist may prescribe home sessions, too.

They use high levels of hydrogen peroxide (30% to 35%) with silica to make a powerful whitening gel. They may try a number of techniques including, adding fluoride or calcium for the purpose of remineralization of enamel, which strengthen enamel while whitening your teeth.

For maximum whitening and speed, dentists can use heat and light techniques. You may have seen the blue light which is held against teeth to break up the gel in whitening process. Some at-home whitening kits also come with these LED devices.
