NEED A DENTIST? ZOCDOC  WILL HELP YOU FIND ONE IN YOUR AREA

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

However, you can accelerate the process by consuming staining foods and drinks. 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.
