Soft guards
The thinnest and most flexible option, made of a pliable plastic similar to a sports mouthguard. Clear or slightly cloudy, and the most comfortable for mild grinding or occasional clenching.
Preventive care
A custom bite guard is a clear, thin tray of dental-grade plastic, molded to the exact shape of your teeth. It looks a lot like a retainer — smooth, see-through, and worn over the upper or lower arch to protect your teeth while you sleep.
The basics
A custom bite guard is clear or lightly translucent, made from smooth, tray-shaped plastic. It's molded to the precise contours of your teeth, so it fits like a second skin over your upper or lower arch — not bulky, not padded, just a thin shell that follows the shape of your bite.
Most patients describe it as looking like an orthodontic retainer. It has no wires, no brackets, and no color — just a polished, see-through surface. Depending on the type, it may cover just the biting edges of your teeth or extend to cover the whole tooth surface.
Because it's custom-molded from an impression or digital scan of your own teeth, it sits precisely in place without shifting — unlike the bulkier, one-size-fits-all guards sold in stores.
Not all guards are the same
The thinnest and most flexible option, made of a pliable plastic similar to a sports mouthguard. Clear or slightly cloudy, and the most comfortable for mild grinding or occasional clenching.
A rigid, clear acrylic shell, thicker and smoother than a soft guard. Built to withstand heavier, more forceful grinding without wearing through.
What we typically use
A soft inner layer against a firmer clear outer shell — comfortable to wear, durable enough for moderate to heavy grinders. Still clear, still tray-shaped, just slightly thicker than a soft guard alone.
Over-the-counter "boil and bite" guards are bulkier, less transparent, and rarely fit as precisely, since they're shaped by biting into warm plastic rather than molded from your own teeth. A custom guard from our office is thinner, clearer, and fits so well that most patients forget it's in until morning.
Why it matters
From scan to fit
01
Digital scan or impression.
We capture the exact shape of your teeth with our intraoral scanner — no goopy tray, no gag reflex.
02
Guard type selected.
Based on how much you grind or clench, we choose soft, hard acrylic, or dual-laminate material for your guard.
03
Molded and fitted.
Your guard is molded to your scan, then tried in and adjusted so it sits securely without shifting or rubbing.
Common questions
A bite guard is a clear or translucent piece of custom-molded plastic shaped like a thin tray. It fits snugly over the upper or lower teeth, resembling a retainer or a mouthguard, and has a smooth, polished surface.
Thickness depends on the type and the amount of grinding or clenching it needs to withstand. Soft guards are typically the thinnest, hard acrylic guards are thicker and more rigid, and dual-laminate guards fall in between with a soft inner layer and a firmer outer shell.
Most custom bite guards are clear or translucent, which is why they're easy to mistake for an orthodontic retainer. Some over-the-counter versions are opaque or colored, but the custom guards fitted by a dentist are almost always clear plastic.
A bite guard (or night guard) is designed to be worn while sleeping to protect teeth from grinding and clenching. A sports mouthguard is designed to be worn during athletic activity to cushion the teeth and jaw from impact. Both are custom-molded plastic trays, but they're built for different situations and often differ in thickness and shape.
If your jaw aches in the morning or you've noticed worn or chipped teeth, a custom bite guard may be the answer. Start with a first visit and we'll check your bite and fit you for one.
