The Ultimate Guide to Buying Custom Gold Grillz
June 15, 2026 5 min read By GIA Gemologist

Selecting the Right Gold Karat
Gold grillz are custom-molded caps made to fit over your teeth. The karat rating determines the gold content and durability:
- 10k Gold: Contains 41.7% pure gold. It is the strongest and most scratch-resistant, making it perfect for daily wear. It has a lighter yellow gold shade.
- 14k Gold: Contains 58.3% pure gold. It is the industry standard, offering a beautiful classic gold shine and excellent durability.
- 18k Gold: Contains 75% pure gold. It is softer and has a rich, deep yellow shade, ideal for premium luxury settings.
Diamonds vs. Moissanite Settings
To add shine to your grillz, we set gemstones on the caps. You can choose natural diamonds, lab-grown diamonds, or high-brilliance Moissanite. Moissanite is a popular choice because it has a higher refractive index than diamonds (reflecting more light) at a fraction of the cost.
How the Molding Process Works
To ensure a flush, comfortable fit that does not damage your enamel, we take a physical dental impression of your teeth. We use dental-grade alginate molds directly in our Springfield Town Center storefront, ensuring your grillz click on securely.
