What to Look For in Teeth Whitening Pens

When choosing a teeth whitening pen, it’s best to consider the following:

Active Ingredients

Most of these products contain hydrogen or carbamide peroxide. Both effectively lighten teeth, although they work differently:

  • Hydrogen peroxide — Has stronger whitening power but can trigger tooth sensitivity. It’s best for people who want intense results in a short time.
  • Carbamide peroxide — Slowly whitens over time and is less likely to cause sensitivity. It’s best for sensitive teeth with light stains and yellowing.

Watch out for other ingredients that can reduce sensitivity, remineralize teeth, or enhance the product’s whitening effects. Some examples include carbomer, potassium citrate, glycerin, and minerals.

Value for Money

You want a teeth whitening pen that can give you enough treatments for the money you’re spending. Some are cheap but only contain a small amount, so you might end up spending more to achieve the results you want. Other pens are more expensive but contain more serum, saving you money.

Brand Reputation

Lastly, you’ll want to check the brand’s reputation. If a teeth whitening pen performs well, customers will likely have good things to say about it. You can check reviews on their website or other popular e-commerce sites, so you’ll have a general idea of the brand’s effectiveness and safety.

Final Recommendations

At NewMouth, we think teeth whitening pens are an excellent choice for:

  • Slightly yellow teeth and mild stains
  • Quick on-the-go treatments
  • Keeping your teeth white

But if you want to see bigger changes in your smile, better treatments are available like teeth whitening kits and whitening strips.

Before deciding, remember to consult a dental professional who can assess your teeth and determine which brands may work best for you.
