Teeth Stains
External strains are those that appear on teeth surface and are easier to remove. Internal strains are those that form under the teeth surface (under Enamel) and are much harder to bleach. While external strains are results of smoking, drinking and eating Internal ones are results of aging process, teeth trauma and damages, exposure to antibiotics, minerals, etc... Not so long ago dentists thought that internal teeth strains were impossible to remove but today it's known that even they can be bleached with long whitening treatments that last several months, even a year or more... But the most important is that they can be whitened just like the surface ones.
