Why Dentists Recommend Custom Night Guards in Canada
If you wake with sore jaws, dull headaches, or sensitive teeth, you may be grinding or clenching at night. A custom night guard can protect your teeth and reduce jaw pain. Here’s how dentist-made guards work, why they’re different from store-bought versions, and how a personalized plan keeps you comfortable—and consistent.
Do I really need a custom night guard?
Custom night guards cushion your teeth and spread biting forces so enamel doesn’t wear down and jaw joints aren’t overworked. They fit closely, feel more natural, and are easier to wear consistently—key reasons dentists recommend them over generic, one-size devices.
What a Night Guard Is (and what it’s not)
A night guard is a clear, removable dental appliance worn while you sleep. It creates a protective barrier between upper and lower teeth. This barrier absorbs pressure from grinding (bruxism) and clenching, and it helps calm overworked muscles around the temporomandibular joint (TMJ). A night guard doesn’t cure the habit by itself, but it prevents damage while you and your dentist tackle the root causes.
Common signs you might need one
Morning jaw soreness, headaches at the temples, flattened or chipped teeth, sensitive teeth, trouble opening wide, and sleep disruption. Many Canadians don’t realize they grind until a dentist spots wear patterns. Studies suggest roughly 8–10% of adults grind at night, but the true number may be higher because it often goes unnoticed.
Custom Guard vs Store-Bought: Why Fit Drives Results
Store-bought (boil-and-bite) guards seem easy, but they’re often bulky, loose, or uneven. That can make your jaw work harder, not less, and many people stop wearing them after a few nights.
Custom guards are made from precise dental scans. Your dentist can fine‑tune thickness, edges, and bite contact so the guard feels natural. That comfort is what leads to nightly use—exactly what protects your teeth over time.

Types of Night Guards (matched to your needs)
Different problems call for different materials and designs:
- Soft guards: Cushioned feel for mild grinding or short-term use.
- Dual-laminate (soft inside, hard outside): Good for moderate to heavy clenching and grinding—comfortable yet durable.
- Hard acrylic guards: Highly durable with precise bite control; often used when jaw joint (TMJ) issues or orthodontic goals are part of the plan.
Your dentist will consider your bite, muscle activity, enamel wear, and past dental work (fillings, crowns, veneers). They’ll also watch for sleep-related issues that can worsen grinding.

Personalization: The Reason Dentists Prefer Custom
1) Fit and comfort build nightly habits
The best guard is the one you’ll actually wear. A custom-fit device sits snugly, doesn’t rock or rub, and keeps your bite stable. That’s how you go from “I’ll try it” to “I wear it every night.”
2) Bite and jaw alignment matter
Grinding forces aren’t equal. Your dentist will balance contacts across the guard so no single tooth takes the hit. This reduces jaw strain and helps calm muscles. When TMJ symptoms are part of the picture—clicking, popping, facial pain—a properly adjusted guard can be part of a broader plan to reduce flares and protect the joint. If TMJ is on your mind, this comprehensive guide to TMJ disorders explains causes, symptoms, and care options.
3) Material and thickness match your forces
Light grinder? You may do well with a slimmer, softer design. Heavy clencher? You’ll likely need a thicker, dual‑laminate or hard acrylic guard. Your dentist decides based on visible wear, your symptoms, and how your jaw muscles test during the exam.
Regular Monitoring and Small Adjustments
Custom guards aren’t “set and forget.” Your dentist will check the fit, polish rough edges, and adjust your bite contacts so the guard continues to feel natural as your muscles relax. This routine tuning is quick but makes a big difference in comfort.
Part of a Bigger Plan: Stress, Sleep, and Bite
Grinding is often linked with stress, sleep quality, and bite alignment. A strong plan may include:
- Stress management: Simple breathing routines, stretching, and good sleep habits can calm jaw muscles.
- Bite or orthodontic corrections: If your bite is way off, orthodontics or selective bite adjustments may help long term.
- Protection for dental work: Guards shield crowns, veneers, and fillings from cracks and fractures.
Many people notice fewer morning headaches, less neck and facial tension, and better sleep once they stick with their guard. If you want a plain-language walkthrough of how this protection works, skim this overview on custom night guard benefits for bruxism.

Cleaning and Care (takes less than two minutes)
Rinse the guard after each use, brush gently with a soft toothbrush (no gritty toothpaste), and let it air-dry in a ventilated case. Avoid hot water, which can warp the material. Bring it to checkups so your dentist can clean and inspect it.
What Results Should You Expect?
In the first week, expect your jaw muscles to start relaxing. Within a few weeks, tooth sensitivity and morning headaches usually improve. Over months, you should notice less wear on your teeth. If discomfort or new symptoms pop up, call your dental office for a quick adjustment.
Cost and Coverage in Canada
Prices vary by design and location. Many employer or private plans cover part of the cost. Ask your clinic to check your benefits and submit paperwork. A well-made guard often lasts several years, especially with regular polishing and adjustments.
When to See Your Dentist Sooner
- Persistent jaw or ear pain, or painful clicking/locking
- Cracks, chips, or sharp edges on the guard
- New headaches or tooth sensitivity after you started wearing it
- Any fit change after dental work or a new crown
How Night Guards Fit Into Headache or TMJ Care
Night guards can reduce clenching forces that trigger muscle-based headaches and TMJ flares. But they work best when paired with simple stretches, posture breaks during screen time, and steady sleep routines. If you’re still waking sore, your dentist may add physical therapy exercises, jaw relaxation coaching, or adjust your bite on the guard.

Conclusion
Custom night guards protect teeth, calm muscles, and ease TMJ stress—especially when they’re part of a personalized plan. The right fit and regular tune-ups make them comfortable to wear every night. Pair your guard with better sleep habits and stress tools, and you’ll protect your smile for the long run.
FAQ
Do night guards stop grinding?
No. A guard doesn’t stop the habit, but it protects teeth and reduces muscle strain. Many people grind less as muscles relax and stress improves.
How long does a custom night guard last?
With good care, many last 3–5 years or longer. Heavy grinders may need earlier replacement. Your dentist will watch for wear at checkups.
Which is better: custom or over-the-counter?
Custom. Better fit means better comfort and more consistent use. A dentist adjusts bite contacts so forces spread evenly and your jaw can relax.
Will a night guard help with TMJ symptoms?
Often, yes—by reducing overload on the joint and muscles. It’s most effective as part of a larger plan. For background, see this clear TMJ overview.
How do I clean it?
Rinse after use, brush gently with a soft brush, air-dry in a ventilated case. Avoid hot water and harsh cleaners. Bring it to your cleanings for a professional refresh.
