While most people start to see their first signs of tooth discoloration in their teenage years, most adults will experience some degree of staining by the time they reach middle age. Many factors can make teeth stained, including smoking, drinking coffee or tea, and eating certain foods. Fortunately, several ways exist to whiten teeth and restore them to their natural color. Professional teeth whitening is one option, but it can be pretty expensive. Several over-the-counter teeth whitening products, including toothpaste, gels, and strips, are also available. However, before using any of these products, it is essential to consult with a dental professional to ensure that they are safe for your particular situation. With a little effort, it is possible to achieve brighter teeth and a more radiant smile.
