The Science Behind Teeth Whitening Strips

Teeth whitening strips have become very popular over the counter dental products which are easy, handy and instantly brightens your teeth. These strips are applied directly to the teeth and left in place for a certain amount of time, allowing the whitening gel to remove surface stains and lighten the teeth.

What Are Teeth Whitening Strips

Teeth whitening strips typically use specific teeth whitening active ingredients to remove stains and discoloration. The main active ingredient in most teeth whitening strips is hydrogen peroxide or a form of carbamide peroxide. These substances work by releasing oxygen molecules that penetrate the enamel and break down the pigmented molecules responsible for staining. Common ingredients used in teeth whitening strips are:

Hydrogen Peroxide (H2O2):

 This is a bleaching agent that releases oxygen molecules when it comes into contact with teeth. It effectively breaks down external (surface) and some internal (internal) stains. Hydrogen peroxide is available in various concentrations, with higher concentrations generally providing more significant whitening effects but also potentially increasing the risk of tooth sensitivity.

Carbamide Peroxide:

 Carbamide peroxide is a compound that breaks down into hydrogen peroxide and urea when applied to teeth. The urea component further helps in breaking down scars. Carbamide peroxide is often used in teeth whitening products because of the controlled release of hydrogen peroxide, which can reduce sensitivity compared to using hydrogen peroxide directly.

Other oxygenating agents:

 Some teeth whitening strips may use alternative oxygenating agents that release oxygen and help remove stains. These agents may include sodium percarbonate or sodium perborate.

Adhesive strips:

 In addition to active whitening agents, the strips themselves are made of a thin, flexible material that sticks to the teeth. These strips are usually coated with a whitening gel that contains active ingredients.

Other Ingredients:

 Teeth whitening strips may contain additional ingredients to improve product effectiveness and user experience. They may contain stabilizers, flavoring agents, and adhesives to ensure that the strips are held in place during application.

The concentration and composition of these active ingredients may vary between different brands and products. It is recommended to follow the instructions for use provided by the manufacturer to ensure the safe and effective use of teeth whitening strips. Furthermore, it is advisable to consult a dentist before using any teeth whitening product, especially if you have dental problems or concerns.

IMPORTANT NOTE: JUST BECAUSE THE INGREDIENTS ARE BEING LISTED DOES NOT MEAN THAT YOU GO AND START BUYING THEM AND END UP APPLY THEM ON YOUR TEETH. NO MATTER WHAT, DONT APPLY THESE INGREDIENTS ON YOUR TEETH.

Understanding Why We Use Teeth Whitening Strips

Teeth whitening strips are used as cosmetic dental products to make teeth whiter and brighter by reducing stains and discoloration. They are a popular option for individuals who want to improve the aesthetics of their smile. The main reasons for using teeth whitening strips are:

Stain removal:

 Over time, teeth can be stained by factors such as colored foods, beverages (such as coffee, tea, and red wine), tobacco use, and poor oral hygiene. Whitening strips are designed to remove these extrinsic stains from enamel, helping to restore teeth to a more youthful and vibrant appearance.

Color correction:

 Teeth can also develop intrinsic discoloration, caused by factors such as aging, certain medications, genetics, or dental trauma. Although teeth whitening strips are more effective at removing extrinsic stains, they can also provide some improvement in cases of mild intrinsic discoloration.

Boosting confidence:

 A bright smile is often associated with improved self-confidence and self-esteem. Using whitening strips to achieve a whiter smile can lead to a more positive self-image and increased confidence in social and professional interactions.

Affordability and convenience:

 Teeth whitening strips are generally more affordable than professional in-office whitening treatments. They also offer the convenience of at-home use, allowing individuals to fit treatment into their schedule without the need to visit the dentist's office.

Non-invasive option:

 Teeth whitening strips provide a non-invasive way to improve the appearance of teeth. Unlike some other cosmetic dental procedures, they do not require drilling or changing tooth structure.

Gradual Results:

 Whitening strips usually provide gradual results over a period of time, such as a few weeks. This gradual process can lead to a more natural-looking whitening, as sudden dramatic changes can sometimes look unnatural.

Customization of Use:

 Many whitening strip products offer different levels of whitening, allowing individuals to choose a product that best suits their desired level of brightness. This custom helps prevent excessive whiteness and sensitivity.

Professional whitening care:

 For individuals who have previously undergone professional teeth whitening treatment, whitening strips can be used as a maintenance option to prolong the effects of the initial treatment.

It is important to note that although teeth whitening strips can be effective for many people, individual results may vary based on factors such as the severity of staining, tooth sensitivity and overall oral health. It is recommended to follow the instructions for use provided by the manufacturer and consult a dentist before starting any teeth whitening procedure, especially if you have any dental problems or concerns.
