Cavities and gum problems aren't the only issues in your mouth: the prevalence of acidic foods and drinks is, according to dental studies, eating away at tooth enamel. To counteract the loss of enamel, oral health giant Crest is bowing Pro-Health Enamel Shield toothpaste. The product binds to enamel to create a micro-thin protective layer against the dangers of acid. The toothpaste also protects against cavities, gingivitis, plaque, sensitivity, tartar, fresh breath and whitening. Crest, a division of Cincinnati-based Procter & Gamble, is also producing a companion rinse under the same name, and both products will be available as a fresh mint flavor. The suggested retail price ranges from $1to $4.25 for varying sizes. More information is available at www.crestprohealth.com.
