What to Look for in At-Home Teeth Whitening Products

Teeth whitening products that list hydrogen or carbamide peroxide as the main active ingredient are the most effective.

Hydrogen peroxide solutions whiten your teeth by oxidizing them. Most treatments do not cause significant changes in tooth enamel.

However, some treatments can cause tooth sensitivity and enamel changes. This risk increases if you leave the serum on your teeth for a long time. High peroxide concentrations can also cause these issues.

At-home teeth bleaching products that contain 5 to 10 percent hydrogen peroxide or 35 percent carbamide peroxide are considered safe. Make sure you follow the instructions as directed and don't overuse the gels.

Colgate Optic White

Colgate Optic White Advanced Whitening Toothpaste

Best Whitening Toothpaste

The product contains 2 percent hydrogen peroxide, which dentists recommend for whitening. It also contains fluoride to protect against cavities. 

Whitening toothpaste is not as effective at whitening your teeth as LED kits or Whitestrips. But it can help remove and prevent surface stains. Therefore it should be used in addition to one of these other methods.

Cost: $

Colgate Optic White Mouthwash

Colgate Optic White Whitening Mouthwash

Best Whitening Mouthwash

Colgate Optic White Whitening Mouthwash contains 2 percent Hydrogen Peroxide. This can slightly help remove surface stains. However, whitening results from mouth rinse alone will not be as effective as an LED whitening kit or Whitestrips.

Because it does help prevent new stains, whitening mouthwash is best used in addition to another whitening product.

Cost: $

colgate led teeth whitening kit

Colgate Optic White Advanced LED Whitening

Best All-in-One Whitening Brand

Colgate Optic White Advanced LED Whitening only takes 10 minutes a day for 10 days to see results. It is clinically proven to deliver brighter teeth up to 6 shades whiter.

Is Teeth Whitening Effective?

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.
