Teeth Bleaching Products – The Facts

Teeth bleaching products are essentially teeth whitening products available over the counter or those used at the dentist’s office.

Hydrogen Peroxide in Your Mouth!

Hydrogen peroxide, a commonly used teeth bleaching agent, is contained in almost all teeth whitening products. These products target stain particles from food and beverages that have been trapped in layers of tooth enamel.

As you are probably aware, even with regular brushing and flossing stains on your teeth develop over time. When all else fails hydrogen peroxide may be the only way to regain whiter shades of your teeth.

Safe in Small Amounts?

A dental whitening procedures can take 30 minutes to an hour, while over the counter products may need to be used for short periods over several days. This is due to the dentist using a much more powerful bleaching solution.

According to some researchers, the hydrogen peroxide contained in these teeth bleaching products is carcinogenic (cancer causing) and tooth decaying. Furthermore, many toothpastes and kits have been criticized for containing particles that can wear off the tooth enamel and if overused causes adverse effects.

Even though a dental whitening procedure is very expensive it is considered the safest way to whiten your teeth due to the control over the bleaching solution’s quality and quantity. But, the criticism faced by other teeth whitening products makes them a matter of debate. So, is there any truth in their accusations?

Are Teeth Whitening Products Safe to Use?

Whitening products from trusted manufacturers are not harmful when used as directed. But this is where much of the debate arises.

Each product contains different ingredients and has a unique method of application. It is vital that the user understands how to use the product by reading the usage instructions completely. Then by following these directions they will be able to use the product safely.

Overuse of any teeth whitening product can be harmful to your dental health.

They end up overusing these products or brushing too roughly which causes their tooth enamel to wear off. This, in turn, results in teeth sensitivity and decay.

Although teeth whitening products are safe to use, caution must be exercised in case your teeth are allergic to whitening agents.

The toxicity of hydrogen peroxide is baseless as per credible scientific evidence. As per them, there is no association found between teeth whitening and cancer.

When whitening procedures are performed correctly, the exposure to hydrogen peroxide is also minimal. Hence, there is no harm. While gum irritation and sensitivity do occur with whitening, they are generally mild to moderate and disappear within a few days.
