Rainbow diamond tooth gem.
Tooth gems or tooth jewelry are only a few millimeters wide, but they may really enhance a megawatt smile. The procedure is non-invasive and does not damage any tooth structure. It's an easy procedure like the way we put braces on and costs less than a filling.
Nothing extra is required to take care of a tooth gem, just routine oral hygiene. It's also easy to be removed if you don't like it. Again, no tooth structure will be damaged during the removal procedure.
