I have only had my teeth whitened once previously and it was at a Dentist's office, using the trays. I had seen a difference back then, but nothing significant.
My issue is that I have nice, healthy teeth but not much enamel. I went online and came across Tamar's business and decided to try it out.
I went in yesterday and did 3 15 min sessions. I did not experience any pain or sensitivity. I have a small mouth and the my mouth/jaw did not feel strained.
I can tell that my teeth look less stained than they did before I went in. I did not expect to end up with white teeth because that is just not logical.
I plan to go back again for another treatment assuming that the color doesn't change much over the next couple weeks. I will probably go back in 3-6 months and see if I can get closer to the color I'd like to have.
