Scientists have developed a substance called CaviStat to help in the fight against cavities. CaviStat contains an amino acid that can duplicate the remineralization effects of saliva. Studies have shown it to be more effective than fluoride at preventing cavities in children.
And now some good news for your child's sweet tooth: CaviStat now comes in chewable mints called BasicMints. A study of BasicMints showed reduced cavities in children who ate them after brushing with a fluoride toothpaste. The study was funded by Ortek Therapeutics, the company that has licensed CaviStat. Ortek is working on getting FDA approval for BasicMints.
Ask your dentist about them.
