How a Night‑Guard Protects Your Jaw and Your Teeth

If you wake with a tight jaw, a dull headache, or teeth that feel worn, nighttime grinding may be to blame. A custom night‑guard is one of the most effective and least invasive ways to protect yourself while you sleep.

What a Night‑Guard Does

A night‑guard is a custom‑fitted appliance you wear over your teeth while sleeping. It creates a smooth, cushioning layer between your upper and lower teeth so that clenching and grinding no longer wear down enamel or chip fillings and crowns.

Beyond protecting the teeth, a well‑made guard helps relax the jaw muscles and takes pressure off the joint. Many people find their morning jaw soreness and headaches ease within a few weeks of consistent use, simply because the constant nighttime strain is reduced.

Why Custom Beats Off‑the‑Shelf

Drugstore guards can help in a pinch, but they are bulky, fit loosely, and often get spat out or worn through quickly. A poor fit can even shift your bite and add discomfort rather than relieving it. Comfort matters, because a guard only works if you actually wear it.

A custom guard made from an impression of your teeth fits snugly and comfortably, so it stays put and feels natural. It is built from durable material matched to how heavily you grind, which means it lasts longer and does its job better night after night.

Getting Fitted at Cambie Dental

The process is simple and comfortable. We take a precise mould or scan of your teeth, and your guard is crafted to fit only you. When it is ready, we check the fit and make small adjustments so it feels right from the very first night.

We also show you how to clean and store it so it lasts, and we check its condition at your regular visits. If you suspect you grind your teeth, mention it at your next appointment in Vancouver, since a small step now can spare you bigger dental repairs later.
