Custom-fitted vs pre-made grillz

What pre-made actually means

A pre-made set is cast to a generic tooth shape in a few sizes. Some come with a silicone bar you heat and bite into, moulding the silicone — not the metal — to your teeth. The cap itself never changes shape.

That means the metal contacts your teeth at whatever few points happen to line up. Everywhere else there is a gap, and every gap collects food and moisture against your enamel.

What custom means here

We take a dental impression of your actual arch, pour a model from it, and build the caps on that model. The inside surface of each cap is a negative of your tooth, so it grips by shape rather than by pressure or adhesive.

The visible result is different too. Custom caps follow your natural tooth outline, so the set reads as part of your smile instead of a plate sitting in front of it — which is exactly what pre-made sets look like in close-up photos.

The safety difference

Dental bodies are consistent about the risks of ill-fitting oral appliances, and they are the same risks we see when someone brings in a cheap set: trapped plaque, gum irritation, uneven bite pressure on a couple of teeth, and enamel wear where a hard edge rubs.

None of these are dramatic overnight. They are slow, and they are avoidable with a set that distributes contact across the whole tooth surface.

When pre-made is a reasonable choice

We will say it plainly: if you want a set for one costume party, a music video, or to test whether you even like the look before spending real money, a pre-made set is fine. Wear it for the evening, take it out to eat, clean it, don't sleep in it.

What it is not is a daily-wear piece, and it is not something to compare on price against custom work — they are different products.

Mould kits by post

Home impression kits sit between the two. Done carefully they produce a usable model; done badly — the most common outcome — they produce a distorted arch, and the workshop builds a perfect set to the wrong shape.

If you can't get to Bangkok, ask us about a kit and we'll talk you through it properly before anything is cast. If you can get here, an in-person impression takes minutes and removes the guesswork entirely.
