Gleem

Gleem is an American brand of oral hygiene products, including toothpastes and electric toothbrushes, owned by Procter & Gamble.

When Gleem II with fluoride and "green sparkles" was introduced within several years, the brand achieved a 9% share of the toothpaste market.

Crest has been known to carry increments of sugar as well as artificial flavoring and coloring, aimed at coaxing young children and preteen enticement to prompt oral hygiene.

In addition, Crest contains stannous fluoride which has been said to strengthen and protect tooth enamel, calcium and fight gingivitis and bacterial infection, but is often irritant, abrasive and stains, while sodium fluoride (contained in Gleem) is more gentle, does not stain, but requires more application (longer or more brushings) to further prevent bacterial infections and can have little effect with calcium.

In August 1976, Procter & Gamble transferred Gleem from Wells, Rich, Greene to the Leo Burnett Company of Chicago, Illinois.
