Do you often find yourself hiding your mouth when speaking or taking pictures because your teeth have lost their luster? You are not alone. Tooth discoloration occurs naturally as you age. In addition, the foods and drinks you consume, poor oral hygiene, or smoking can accelerate the darkening of your enamel. To restore a bright smile, there are several whitening products and treatments that you can use, but which is best? To make the right choice, it is important to understand how each option works and the results you can expect to achieve. While there are many over-the-counter solutions, it is often better to get a professional treatment from your Lehigh Valley dentist.
