I gave up on Amazon once I wasn't able to buy the replaceable toothbrush heads for my electric toothbrush. Try ordering the name brand oral-b ones and see what shows up (in my case, cheap Chinese knockoffs that lasted about a week instead of however many weeks they're supposed to). I honestly miss being able to go to a unique store to buy things - that way you could look at what you were actually buying and (maybe!) find something better for what you're trying to do.
