I've tried brushing with baking soda and hydrogen peroxide for 3 weeks with no success. Perhaps my teeth are not stained and so there is no way to get rid of the yellow. Could it be that only stained teeth be whitened and not teeth that are naturally yellow in color? My teeth are strong and thick and I heard that can cause teeth to be yellow since less light can pass through it.
--------------------
It's true, if you're a coffee drinker or smoker your teeth can yellow quite a bit over time. Over the counter teeth whitening can work pretty good, but I think in your case the stronger percentage of peroxide from a dentist would work better. I would recommend the trays instead of "in office" bleaching. Tray whitening can last over 18 months where as the "in office" bleaching only lasts about 6 months (Plus it costs twice as much). I'm not sure that thicker teeth have much to do with it, but genetics in general might be a factor. Ask your dentist about a bleach that has 16- 22% carbamide peroxide. I've seen dramatic results!! Hope this helps -Dental Assistant
