Teeth stains are inevitable due to our consumption of a variety of foods and drinks (soda, spicy food, coffee, etc.). However, advanced teeth whitening technology has enabled dentists to whiten teeth without adversely affecting the tooth structure.
Almost all whitening methods are similar in concept, but some are much more effective because of the way the whitening material is delivered to the teeth. Another contributing factor is the concentration of the material, which is why less potent over-the-counter whitening systems usually don’t give patients the results they are hoping for.
