Launched in 1984, Extra was Wrigley's first sugar free gum offering in the U.S. Extra gum is known for its incredible, long-lasting flavors. Extra is also available in a variety of distinctive gum flavors, specifically tailored to local tastes, in geographies including Australia, Canada, China, Germany, Hong Kong, New Zealand and Taiwan.

Wrigley’s Orbit and Extra sugar-free chewing gums were the first chewing gums to be awarded the American Dental Association’s Seal of Acceptance. The ADA Council on Scientific Affairs acceptance of Orbit and Extra is based on its findings that the physical action of chewing Orbit or Extra sugar-free gum for 20 minutes after eating stimulates saliva flow, which helps to prevent cavities by reducing plaque acids and strengthening teeth.
