Carrie Underwood's Beauty Secret For Whiter Teeth

Country music superstar Carrie Underwood has a gorgeous smile. And believe it or not, she's got all her own teeth, which is actually unusual to see these days. It seems like every Hollywood celebrity goes with super-huge, super-white porcelain veneers. Carrie Underwood is sharing her beauty secret for whiter teeth with the December issue of InStyle.

Her favorite toothpaste: Bright Smile Whitening Toothpaste ($16.99, at Smilox.com).

"Because my teeth are sensitive, I can't get them professionally whitened--or even use strips. This toothpaste does the trick," Carrie says.

So, let's take a look at Bright Smile Whitening Toothpaste. The tube is not the cheapest at $16.99 for 4.2 oz.. But it does contain an effective formula for eliminating stains and whitening teeth nicely.

Most people know about Bright Smile through their dentist as the 1 hour whitening process. The treatment features a hydrogen peroxide-based gel activated by a specialized light energy to get  teeth  up to "9.3 shades whiter".
Average Brite Smile Cost: $375

The company also offers at-home products such as Carrie Underwood's fave whitening toothpaste to bleach teeth.

We think Carrie's smile looks healthy, bright and white in a genuine way.

Do you use any type of whitening toothpaste or strips or trays?
