What Causes Tooth Discoloration?

Teeth inevitably become discolored over time, which is a natural part of aging. 

However, consuming staining foods and drinks can accelerate the process. Coffee, tea, red wine, artificially colored foods, and even dark berries can stain your teeth. Certain medications, tooth trauma, and genetics can also play a role in discoloration. 

Fortunately, there are many ways to whiten your teeth without having to give up your favorite foods.

Depending on your needs, budget, and level of discoloration, common at-home teeth whitening options include:

  • LED whitening kits
  • Whitening pens and gels
  • Whitening strips 
  • All-natural whitening products
  • Whitening toothpaste
  • Whitening mouthwash 

How to Choose the Best At-Home Teeth Whitening Kit

Whether you prefer all-natural or professional-grade whitening products, there is an at-home whitening solution available for every need.

Professional-grade at-home whitening products contain either hydrogen or carbamide peroxide.

Peroxide is the main active ingredient in professional-grade whitening products that dentists use in their offices. The main difference is that at-home whitening products contain less peroxide than dentist-level whitening products. This ensures customer safety. 

Carbamide peroxide penetrates your enamel and reaches the discolored molecules inside your teeth. ​The whitening agent's oxygen molecules interact with the discolored teeth molecules, gently lifting stains. Carbamide peroxide breaks down slower than hydrogen peroxide, so it is safer to use and produces less post-whitening sensitivity. 

The downside of peroxide is that it can cause sensitive teeth and gum irritation. These side effects are typically mild and do not increase your risk of oral health issues.

If you prefer a more natural whitening experience, there are also peroxide-free whitening treatments available.

Most natural whitening strips, toothpastes, and mouthwashes on the market use essential oils and botanicals to whiten teeth. These products typically take longer to see results but do not cause sensitivity or pain.

Are Teeth Whiteners Safe?

Although sensitivity is a common side effect of hydrogen peroxide, this whitening method is safe and effective when used as directed. Hydrogen peroxide gels whiten your teeth through oxidation, and most whitening treatments do not cause significant changes in tooth enamel.

hismile PAP+ Teeth Whitening Kit™

hismile PAP+ Teeth Whitening Kit™

Best for Sensitive Teeth

hismile's teeth whitening kit uses three powerful, enamel-safe ingredients to provide instant results without any sensitivity:

  1. Hydroxyapatite (nHAp) rebuilds the protective layer of teeth and replaces lost minerals.
  2. Phthalimidoperoxycaproicacid (PAP) is clinically proven to whiten teeth without sensitivity or gum irritation.
  3. Potassium citrate helps relieve pre-existing sensitivity and provides long-term protection.

Cost: $$

Best Whitestrips for Sensitive Teeth

These Whitestrips were developed to provide a comfortable at-home whitening experience for people who have tooth sensitivity but still want to brighten their pearly whites. These enamel-safe strips get applied for 30 minutes daily.

Cost: $

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

This LED whitening kit was designed to reduce sensitivity and uses enamel-safe ingredients. If you're a fan of using the same brand for every step of your oral health routine, you can use Colgate whitening toothpaste, mouthwash, and LED kit.

This kit can be used hands-free and doesn’t require a smartphone to use it, making it easy to apply.

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.

Cost: $$$
