I had my teeth whitened the
expensive way in 1999. My dentist took impressions, drilled a lot to
reshape all my front teeth, and then veneered the sixteen most visible
teeth. We spent a lot of time choosing colors, so that my teeth would
not look like they glowed in the dark, but looked natural.
Since then we have had an explosion of reseach about blueberries,
red wine, and dark chocolate being good for you, in addition to, of
course, coffee and tea.
