Getting the smell of incorrect processing off raccoon teeth

I was given some very smelly raccoon teeth from a friend who purchased them without knowing they were boiled carcasses with bleached bones (as soon as he opened the box and the smell hit i knew exactly what it was.) Im unsure how to get the smell out, I didnt even realize the smell could stick to enamel like it can to bone the way it is. Im glad he didnt buy any bones, since they could be beyond saving. Im sure there's a way to get this smell off, so far ive been doing peroxide soaks but it doesn't seem to be doing anything so far, though its only been about 32 hours.
