Cosmetic dentistry is generally used to refer to any dental work that improves the appearance (though not necessarily the functionality) of teeth, gums and/or bite. It primarily focuses on improvement in dental aesthetics in color, position, shape, size, alignment and overall smile appearance.
Aesthetic dentistry uses techniques available to modern medicine to give you a more natural, healthy look. Aesthetic dentists use techniques like regular cleanings, root canal removal, and the restoration of teeth with fillings or bridges to make your teeth look normal and healthy.
