Question:
How is Tooth whitening gel made ?
I was told the main ingredients are Peroxide and Glycerin, which are
very inexpensive.
Why then are gel kits so expensive?
Answer:
If you're talking about the over the counter gels or the "as seen on TV"
kits, the formulations vary from product to product and they are not
expensive. The problem I see with these products is that the tray is
a so-called universal size that doesn't fit most people's mouths. This
makes for wate of gel and a lot of material swallowed. If you're talking
about a bleaching procedure done by a dentist, the material used is
either Carbamide Peroxide or Superoxol (concentrated Hydrogen Peroxide).
Methods may vary and the price could be around $300 to $600. The
difference is you are paying for a service from an expert, not a kit.
