Crest expanded its line of gum health-focused toothpastes with its new Crest Gum and Sensitivity.

Gum sensitivity becomes more of a problem as people age because gums naturally recede over time, exposing areas of the tooth that are not protected by enamel.

The new toothpaste targets the gum line to prevent sensitivity from hot and cold. The technology starts working immediately to provide all day protection, while the sensitivity relief kicks in after three days of use.

It is available in All Day Protection, Gentle Whitening and Refreshing Mint and can now be found at drugstores, mass retailers and e-commerce sites.
