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.
Which one should I buy
Mastic droplets
6 mm
With these smaller, harder tears, you can chew mastic in increasingly larger amounts over longer periods of time to increase the size of your masseter muscle. Progressive overload for your jaw.

Mastic nuggets
17 mm
Premium mastic nuggets (1.59 oz). Hand harvested on the island of Chios in the Aegean Sea, chewing our nuggets is one of the best things you can do for your dental and digestive health. Larger and softer than our droplets. The original “white pill.”

Where it comes from
Greco Gum is hand-harvested on the beautiful island of Chios in the Aegean Sea.
The refreshing piney flavor comes from a single all-natural ingredient. When the resinous sap seeps from the bark of the Pistacia lentiscus tree, it crystallizes and becomes chewable.
Chios is the only place in the world the trees grow. The island’s unique microclimate and soil formation result from ancient underwater volcanic activity.
