Tooth Gem Kit Question

Hello everyone.

I recently came across tooth gem kits and I'm intrigued by the idea of adding some sparkle to my smile! However, I'm unsure about a few things before diving in. Firstly, how safe are these kits for my teeth? I’ve heard mixed reviews about potential damage or staining.

Also, what type of adhesive is typically used in a tooth gem kit, and how long do the gems usually last? Lastly, has anyone had a particularly good or bad experience with a specific brand? Any tips or recommendations would be greatly appreciated as I consider enhancing my smile with some tooth gems!

Thanks in advance!
