Gum tattoos are nothing new, though. Women from West African countries like Senegal have been tattooing their gums black for the sake of beauty for years.
All of the gum tattoos you'll see here are hand poked by tattoo artists Blame Max and Indy Voet. After all, tattooing with a machine in such vulnerable places would be quite difficult. While designs are kept as minimalistic as possible the gum being such a small space to work on, it doesn't fade as easily as lip and tongue tattoos — given that you have a decent tattoo artist to work on it, of course.
