10K vs 14K vs 18K gold grillz

If you are shopping for gold grillz in Toronto, the first real decision is not colour or style — it is karat. Karat determines how much pure gold is actually in your grillz, and it quietly shapes everything else: colour depth, how the metal wears over months of use, and what it costs per tooth. At Grillz Toronto we cast custom pieces in 10K, 14K and 18K gold, all moulded from your own teeth with no drilling and no filing, so the choice really comes down to how the metal itself behaves and what you plan to spend.

This guide walks through what karat means, how 10K, 14K and 18K compare side by side, how colour options like white and rose gold fit in, and how to land on the right choice for a single cap or a full set. You can see live pricing and build your own combination any time in our customise tool.

Karat measures how much of a gold alloy is pure gold, expressed out of 24 parts. Pure gold is 24K, but it is far too soft on its own to hold the fine edges of a grill, so jewellers and grillz makers alloy it with other metals — typically silver, copper and zinc — to add strength and shift the colour.

• 10K gold is 10 parts gold out of 24, or about 41.7% pure gold.
• 14K gold is 14 parts out of 24, about 58.3% pure gold.
• 18K gold is 18 parts out of 24, a full 75% pure gold.

The remaining percentage in each karat is made up of other metals, and that mix is what controls hardness and colour. More alloy metal generally means a harder, more scratch-resistant piece; more pure gold means a deeper, warmer colour but a softer metal. That trade-off is the whole story behind choosing a karat for grillz, which get far more daily wear and contact than a ring or a pendant.

At $320 per tooth, 10K gold is our most affordable gold option and, metal for metal, the most durable. Because it contains the highest share of hardening alloy metals, 10K resists scratches, dents and daily wear better than higher karats. If you want a gold grill you can wear often without babying it, 10K is a sensible starting point, especially for a first piece or for pieces worn frequently like a bottom six.

The trade-off is colour: 10K reads as a paler, slightly more muted yellow than 14K or 18K. For most people this is a minor difference once the piece is in the mouth and catching light, but it is worth knowing before you order, especially if you have seen photos of deeper gold tones online and expect an exact match. Compare 10K alongside every other option, including iced and silver pieces, on our full pricing page.

14K gold, at $450 per tooth, is the karat we cast most often, and for good reason — it sits at the midpoint between 10K's toughness and 18K's richer colour. It has a classic, warm gold tone that most people picture when they think of a gold grill, while still holding up to regular wear, talking, and the occasional accidental tap against a glass.

14K is a strong default for a full top and bottom set, mixed metal designs, and pieces meant to be worn for years rather than occasionally. It is also the karat we recommend when someone is unsure which to pick, because it rarely disappoints on either durability or looks. Browse full sets, open-face designs and single caps built in 14K gold in our grillz styles gallery.

18K gold, priced at $540 per tooth, contains 75% pure gold, and it shows. The colour is deep, warm and unmistakably rich — the kind of gold tone that photographs beautifully under flash and catches light differently from 10K or 14K. It is the karat most often chosen for a standout single cap, a fang, or a special-occasion piece rather than an everyday full set.

Because it has the least added alloy, 18K is also the softest of the three and will show light surface marks sooner with heavy daily wear. That does not mean it is fragile — it simply rewards being treated the way fine gold jewellery is: removed before contact sports, stored in its case, and polished occasionally. For an occasional-wear piece or a bold single tooth, the extra richness of 18K is often worth that small trade-off.

Karat and colour are two separate decisions. At every karat — 10K, 14K or 18K — white, yellow and rose gold cost exactly the same per tooth at Grillz Toronto. Yellow gold is the traditional, warm look most people associate with grillz. White gold is alloyed with pale metals and plated with rhodium for a bright, almost platinum-like shine that pairs well with iced pieces. Rose gold gets its pink-toned warmth from a higher copper content in the alloy.

Because the colour choice doesn't change your budget, you're free to mix metals within one set — for example, white-gold front caps with yellow-gold fangs, or a rose-gold single alongside a yellow-gold six. If you're also considering stones, our guide on how much grillz cost in Toronto breaks down how iced pricing stacks on top of metal and karat choices.

A few simple questions help most clients decide. Will this be worn daily or occasionally? Daily wear favours 10K or 14K for their resistance to scratching. Is this a full set or a single statement tooth? Full sets often do well in 14K for the balance of colour and durability, while a single standout cap is a great candidate for 18K. Is budget the deciding factor? 10K delivers genuine solid gold at the lowest per-tooth price on our list.

There's no wrong answer — all three karats are solid, hallmark-quality gold, moulded from your own teeth with no drilling or filing, and all are removable. If you want to see exact totals for the number of teeth you have in mind, our customise tool lets you build a set in any karat and watch the price update live, and our pricing page lists every option side by side, including iced silver from $180 and iced gold from $450 per tooth.

It also helps to think about longevity in a practical way: gold does not rust or corrode, and reputable solid-gold grillz retain their metal value long after a trend has passed, unlike thin gold-plated pieces that wear through to a base metal underneath. Whatever karat you land on, you are investing in something that can be re-polished and still look new for years, rather than replaced every season.

Whichever karat you choose, the process starts the same way: a precise mould of your own teeth, taken at our studio in downtown Toronto, during a home visit anywhere in the GTA, or by mail with an impression kit sent anywhere in Canada. From that mould we wax and cast each cap individually to match the contours of your teeth, so the finished grill fits snugly without glue.

Plain gold sets are typically ready in 5 to 10 days, and gold sets with stones added take 10 to 15 days. A deposit is collected once you've approved the design and before casting begins. Reach out by email at contact@grillz-toronto.com or by WhatsApp to book a mould, or read more about the full process in how it works before you commit to a karat.
