Being of British extraction, and over 50, and on my third set of teeth, I say stay away from Brit teeth pullers!!
Israel inherited some British dental practices and there is a generation of Israelis with terrible teeth. Plus we use a lot of well water, which is heavy in fluoride, which will discolor teeth.
Younger folks all have braces and nice straight capped teeth.
One of the gifts to my children was to make sure they had nice American teeth.
