Dental caries are cavities.

Recurrent dental caries is defined as caries which occurs at or adjacent to a surface of the tooth where dental caries had previously occurred and had been repaired.

Recurrent dental caries is diagnosed like any other caries; through visual, tactile, or radiographic exam.

"Caries" is a synonym for dental cavities. Arrested caries are cavities that have been stopped from developing further by having the appropriate dental work done on them.

There is research on whether or not xylitol can prevent dental caries. From everything that I have read it can help prevent dental caries especially if you chew gum that contains xylitol. Check out www.xlear.com. They have products that contain xylitol.
