How Do Teeth Whiteners Work? | Teeth Whitening Products

Teeth whiteners, like teeth whitening strips, gel, toothpaste, are considered to be effective to whiten paled and stained teeth. You might have heard about them many times before from your dentist, pharmacist, or online forums. Probably, many might also have recommended these teeth whitening products to you. There is no doubt about the effectiveness of teeth whiteners as a teeth discoloration treatment. You might get the desired result in just a few weeks by using them. But, how do teeth whiteners work? How do whitening strips work? Have you ever wondered about this? 

This post will help you discover how teeth whiteners work. You will also learn about some of the best teeth whitening products that are safe to use. But before we come to these points, let’s find out what exactly teeth whiteners are. 

What are Teeth Whiteners? 

Teeth whiteners are a range of over-the-counter teeth-whitening products that effectively remove stains and yellowness from your teeth and make them several shades whiter and brighter. These include whitening strips, whitening gel, activated charcoal powder, specifically formulated toothpaste, a teeth whitening kit with LED light, etc. 

Patients with cosmetic dental problems can use these teeth whiteners without the prescription of a dentist. They can easily use them at home without any guidance from a dental expert. 

No doubt teeth whiteners can whiten your teeth but they are less effective as compared to in-office teeth whitening treatments and procedures because teeth whiteners contain lower strength of stain-removal solutions. They are a great solution for patients with minor teeth discoloration problems. 

How do Teeth Whiteners Work? 

We often receive many different health-related queries at The Health Tonic. “How do teeth whiteners work” is one of those queries we frequently receive from dental patients. If you are one of those who is looking for the answer to this query, the following section is helpful for you.

A broad range of teeth whitening options is out there to choose from. Some teeth whitening options can be used as an at-home treatment while for other options, you need to visit the dental office. You can find certain differences between at-home teeth whitening options and clinic-based whitening treatments. However, all the teeth whitening options available in dentistry are based on a single concept and so they work similarly. 

Teeth whiteners contain peroxides, mainly hydrogen peroxides and carbamide peroxide. These are oxygen molecules that act as an effective bleaching agent for teeth whitening. When you apply a teeth whitener to your teeth, the oxygen molecules in the hydrogen peroxides break down as soon as they come into contact with your teeth. They get activated and start acting as a bleaching solution. They get into the outer layer (enamel) of your teeth and remove all types of stains and yellowness. This process takes time and you may need several rounds of usage of teeth whiteners to get the desired result. 

Except for hydrogen peroxides and carbamide peroxide, teeth whiteners also include fluoride as a supporting ingredient. Fluoride provides complete protection to your teeth during the entire whitening treatment process and minimizes the potential risks of tooth sensitivity and tooth damage.

Now, you might get the answer to “how do teeth whiteners work and how do whitening strips work.” Let’s find out whether they are effective with all types of stains or not. 

Types of Stains Teeth Whiteners Can Treat

Two different types of identified stains can occur on your teeth: extrinsic stains and intrinsic stains.

Extrinsic stains are those that affect only the outer layer of your teeth. These types of stains are caused by smoking, unhealthy eating, and consumption of certain antibiotics. 

Intrinsic stains are characterized by stains that affect the inner layer of your teeth. They are mainly caused by aging, genetics, tooth development disorder, consumption of certain antibiotics, and exposure to highly concentrated fluoride. 

Teeth whiteners, like whitening strips, are effective to treat both these types of stains. However, you may need professional teeth whitening treatments in case of complex paleness and chronic stains.
