Whitening Toothpaste

Whitening toothpaste won't give you the same dramatic results as strips or trays, but it can be used to dial up the results of your primary whitening product, and can help you maintain whiter, brighter teeth between whitening kits. Almost every toothpaste company makes a whitening toothpaste so you have a multitude of choices at your disposal.

Sometimes, whitening toothpastes can cause tooth sensitivity. If you have sensitive teeth, you need to get a whitening toothpaste formulated for your needs. Rembrandt Extra Whitening Toothpaste - Sensitive Teeth (average price; $6.99) doesn't contain the abrasive or acidic compounds found in most whitening toothpastes. Instead, it uses a patented enzyme ingredient called Citroxain that gently lifts stains and whitens teeth for a bright and pain-free smile.
