How to Whiten Your Teeth at Home

Many of the best things in life will stain your teeth. Coffee, tea, red wine, fruit juice, tomato sauce, and even curry. This is why teeth whitening treatment has grown in popularity over the years.

Many dentists offer professional whitening treatments in their office, but these can be very pricey. Luckily, home whitening treatments have grown more versatile, effective, and affordable. But with thousands of over-the-counter products on the market, it can be difficult to know what’s going to actually give you a brighter smile.

Hydrogen peroxide and carbamide peroxide are the active ingredients that whiten teeth. The good news is both of these teeth bleaching whiteners have been proven effective and safe.

Does Teeth Whitening Treatment Work?

With centuries of research-based evidence, both over-the-counter and professional whitening methods are safe and effective. 

Some products (like LED teeth whitening) are more effective than whitening strips and toothpaste. However, both provide some level of teeth whitening. In-office teeth whitening is the most effective option and provides the longest-lasting results.

The key factor in safety is whitening your teeth properly. Always follow the directions provided by your dentist (or the product label for at-home products).

If you do not follow the directions, you may experience negative side effects. These can include:

  • Sensitive teeth
  • Reversed whitening effects (teeth appearing more discolored than before)
  • Gum irritation
  • Loss of tooth enamel (protective layer of teeth), which can lead to cavities
  • Increased risk of tooth fracture and damage

What is LED Teeth Whitening & is it Safe?

LED teeth whitening is safe for at-home use. Current research shows that LED whitening is effective when users follow the manufacturer's protocols.

LED as a light source is a safer alternative to ultraviolet (UV) light, which can cause cell mutations. An LED light does not lead to the mutation of cells or raise the risk of cancer. LED speeds up the whitening reaction without the risks of UV light. 

During the LED teeth whitening process, you’ll apply a bleaching agent to your teeth. The LED light activates the whitening agent and starts the chemical reaction. When this reaction occurs, the blue LED light penetrates the enamel and removes stains.

What is the Best Teeth Whitening Product Available?

It depends on your preference and lifestyle. According to the American Dental Association, home teeth whitening products are safe if used as directed — but overuse could lead to enamel damage. With that in mind, we’ve collected the best teeth whitening kits available:
