Review (5/5): Working on my daughter's calculus
I just realized my daughter hasn't been brushing her teeth well and her bottom 4 front teeth are full of calculus. On first session, it took off a lot. Her issue is severe so it may take several uses but I have faith it'll fix up her problem. She goes to the dentist next month anyway but it's nice to resolve this now so she won't be super embarrassed when she sees her dentist.
