Although many dentists offer professional teeth whitening services, it's often cheaper to whiten teeth at home, and as a result, do-it-yourself teeth whitening kits continue to gain popularity. In fact, the most widely used home remedy for fixing stained or discolored teeth are whitening strips. You can get these strips without a prescription from a dentist, or from your local pharmacy, and can easily apply them at home to restore your teeth to their original color and shine.
