I asked my dentist for a set of whitening trays and the office made them for free, which I appreciated. The only issue I have is that they are kind of crudely fashioned and cover my gums – they look like this. So when some of the bleaching gel spreads, it gets on my gums under the tray and I have no way of wiping it off. Whereas when I Google “whitening trays,” most of them look like this — they are scalloped and only cover the teeth, so you would be able to wipe off any excess from the surrounding gums.

Does this make sense as a request to ask my dentist office for these kind of trays?
