Why Greco Gum?

Jaw Workout

Chewing our mastic gum gives your 4 core jaw muscles — masseter, temporalis, lateral pterygoid, and media pterygoid — a full workout.

Avoid Plastic

Pure chiseling with a single, 100% natural ingredient. No silly silicone jaw devices or petrochemical chewing gum required.

Gut Check

Mastic gum relieves digestive and gastrointestinal issues due to its powerful antimicrobial, antibacterial, and anti-inflammatory qualities.

Refined Taste

The refreshing piney flavor develops from resinous sap that seeps and crystallizes on the bark of the pistacia lentiscus tree.

Rare & Beautiful

Chios’ microclimate makes it the only place in the world this gum can be produced. Like snowflakes, no two tears are the same.

What Nature Wants

Chewing mastic tightens skin and freshens breath while stimulating optimal growth of the maxilla, a wider palate, and larger airways.
