“Smart Charlie’s has really helped with her tooth sensitivity”

My daughter has enamel hypoplasia due to steroid injections for croup when she was two which impacted proper enamel formation for her permanent teeth. Discoloration, caps, and tooth sensitivity caused her to be self conscious of her teeth until Smart Charlie Naturals toothpaste! Smart Charlie’s has really helped with her tooth sensitivity by absorbing necessary natural minerals back into her teeth to help strengthen and protect them. She has also noticed that her smile has become much brighter! Within 6 months of her using this toothpaste, her dentist, the one who said there was nothing they could do to help fix her teeth until she could get veneers at 18, also noticed the positive results and asked what she was using!

Thank you for creating this awesome, natural product that helps strengthen and protect our teeth! 😍
