What Customers Are Saying
“I was told to buy this toothpaste by my dentist because my 6-year-old kept getting cavities. We used it for about 4 months and no cavities at his next visit! The tube seemed to last especially when I put the toothpaste on his brush and I was able to squeeze out the last drop. My son seemed to like the taste and never had a problem using it. I will be buying more.”
