If you are in Boston area and do not have fillings in front teeth, you may qualify for a Teeth Whitening Study. Shoot me an email.

Its at Tufts University School of Dental Medicine at Boston.

If you don't have an SSN, you won't be compensated.

Also,

my own study with application of Ozone to remineralize to the beginning of tooth decay is coming to end. I need just six people to recruit. If you think you have cavities and willing to be in a research study, let me know. We will do the fillings, cleanings and take some X-rays for free and compensate for your time.
