Sent me the droplets instead of the nuggets. But after emailing about the mistake they sent me the right ones and let me keep the droplets. Great gum, great service.

Love the nuggets
I absolutely love this stuff! It’s great in every way. I enjoy the pine taste. The texture, although different from normal gum, is pleasant and lasts a long time. The best part is that it helps my stomach with everything - digestion, heartburn, etc. The nuggets are my fav (compared to the droplets). Wholeheartedly recommend.

Greco Won A Lifelong Customer 🔥
Seriously, best gum ever. Not only has it improved my dental health and breath, but it has also had profound effects on my gut and my mind. There’s something so soothing about the chew, that’s incredibly stress relieving, and the taste is out of this world. Because it’s so natural and piney, it is so incredibly grounding for me, too. Also… Greco has incredible customer service. After telling them my first tin melted, they sent me a brand new one! And since I raved about how stoked I’ve been about Mastic (especially upon researching its use and history throughout the ages), they also…

Weird initial taste, afterwards...
Weird initial taste, afterwards it’s very addictive. Jaw muscles get worked and tired and sore after a solid day of chewing. Love this stuff. Getting some for my mother and sister.

Calms my stomach. Curbs...
Calms my stomach. Curbs hunger a bit. Amazing that I can put a piece in water when not chewing and go back to chew it over and over again over days!

Frequently Asked Questions
What if I don’t like it?
Your first order is covered, no strings. Mastic isn’t for everyone, so if it’s not for you, email us within 30 days and we’ll swap it for the other variant or refund you in full, shipping included. Keep the tin. One per customer, only on our website.
Is it safe for my teeth, fillings, or TMJ?
Greco Gum is much harder than ordinary gum. If you have fragile teeth, recent dental work, or existing TMJ trouble, check with your dentist first.
Either way, ease in: start with a small amount, warm it up gently, and rest your jaw on days it feels sore. If you’d rather not chew at all, our capsules give you mastic without the workout.
Can I chew it every day?
Most customers chew Greco Gum daily, often after meals or during work, study, driving, or training sessions.
A good rule of thumb:
- Start with shorter sessions (15–30 minutes)
- Increase the time as your jaw gets used to it
- If your jaw feels sore or overworked, take a break and treat it like you would any other muscle
As with any food product, listen to your body and adjust your routine if something feels off.

What does Greco Gum actually do?
Greco Gum is a hard, natural gum that gives your jaw a serious workout while you chew. Many customers use it to build a stronger-feeling jaw, keep their teeth and gums cleaner between brushes, and as a post-meal ritual that helps them feel “finished” without dessert or extra snacking.
How do I use it and how much should I chew?
Pinch out a small amount to start:
- Droplets: begin with 5–8 pieces
- Nuggets: begin with 1–2 nuggets
Chew gently until the pieces soften and merge. Once it’s formed a single piece, you can add more if you want a bigger chew.
Because it’s a natural resin, some pieces will be softer or harder. If a piece feels too soft or sticky, let it cool for a moment and combine it with a firmer piece to reach the right consistency.
Most people chew for 30–90 minutes per session.
Why is it more expensive than regular gum?
Most gum is made from cheap gum base, sweeteners, and flavorings. Greco Gum has one ingredient: pure mastic resin from the island of Chios in Greece.
Mastic is a niche crop with limited supply, and the resin has to be harvested, cleaned, and sorted by hand. You’re paying for:
- A single-origin, plastic-free gum base
- Careful grading for chew quality
- A product that lasts far longer per piece than normal gum
Did we miss anything?
What should I expect the first time I chew?
It will feel very different from supermarket gum.
The first 1–2 minutes can be strange: the resin breaks into little pieces, there may be a light dusty coating, and the flavor is strong. As it warms up, the pieces bind together into a smooth, rubbery chew that you can work on for a long time.
Start small, chew slowly, and give it a few minutes to come together. Most people say it’s “weird at first, then addictive” once they’ve tried it a few times.
What does it taste like?
Greco Gum is not sweet. The taste is piney and resinous, with a slight bitterness at first and a fresh pine/cedar note as you keep chewing.
If you’re expecting sugary mint gum, this will be a shock at the beginning. If you enjoy strong, natural flavors (black coffee, dark chocolate, herbal spirits), you’re more likely to love it once you’ve given it a few tries.
What is it made of?
Just one ingredient: crystallized resin from the mastic tree (Pistacia lentiscus var. Chia), grown and harvested on the island of Chios in Greece.
There are no sweeteners, plastics, flavorings, or fillers.
