Night Guard in Mississauga

A custom night guard in Mississauga protects your teeth from grinding and clenching while you sleep. Many people grind their teeth at night without knowing it, and the first signs are often a sore jaw, morning headaches or teeth that look flat or chipped. At River Run Dental Centre, our dentists check your teeth for wear and make a guard that fits your bite.
A night guard is a thin, hard or soft plastic cover that fits over your upper or lower teeth. We’re open 7 days a week, including evenings and Sundays, so it’s easy to fit a visit around work.
Benefits of a Custom Night Guard
Grinding wears down enamel, cracks fillings and puts strain on your jaw muscles. A guard takes that force instead of your teeth.
Protects teeth from grinding and wear
Helps ease jaw soreness in the morning
Protects crowns, veneers and fillings
Made to fit your bite, not boil-and-bite

How We Make Your Night Guard
A custom night guard usually takes two short visits, about one to two weeks apart.
Exam and Bite Check
We look for signs of grinding, check your jaw and bite, and talk about how you sleep.
Scan or Impressions
We take a digital scan or impressions of your teeth, and a lab makes the guard to fit them.
Fitting Your Guard
We check the fit and your bite, adjust any high spots, and show you how to clean it.
Most people get used to a night guard within a week or two. It may feel bulky at first, and you might notice extra saliva for a few nights. If it feels tight, rubs your gums or changes how your teeth meet in the morning, call us and we’ll adjust it.
Why Choose River Run for a Night Guard
We look for the cause of grinding, not only the damage. If your bite, a high filling or a missing tooth is part of the problem, we’ll explain your options before making a guard.

Made for Your Bite
Lab-made guards fit closely, so they stay in place and don't shift your teeth.

Clear Costs, Insurance Billed
We explain the cost first and send the claim to your plan for you.
- Direct billing to most plans
Night Guard Cost in Mississauga
Night guard cost in Mississauga depends on the type of guard and the material. A hard acrylic guard for heavy grinding usually costs more than a soft guard, and a guard for both upper and lower teeth costs more than one. The price covers the exam, the scan or impressions, the lab work and your fitting visit. When you compare the average cost of a night guard in Ontario or look at night guard fees, ask what’s included.
With insurance: many workplace dental plans cover part of a night guard, sometimes once every few years. We’ll check your plan and can send a predetermination first.
Without insurance: we’ll give you the full price before we start. If you’re looking for a cheap or affordable night guard, a store-bought guard costs less up front, but it fits loosely and wears out quickly. A custom guard usually lasts several years.
We’ll also check whether the Canadian Dental Care Plan (CDCP) covers a guard for you.
We Direct Bill Your Dental Insurance
Pay only your share at your visit. We accept most private dental plans, the Canadian Dental Care Plan and several government programs, and we offer payment plans if you don't have insurance.

Teeth Grinding: Causes, Signs and Relief
Teeth grinding (bruxism) is common in adults and children. Common causes of teeth grinding include stress, poor sleep, sleep apnea, caffeine or alcohol late in the day, some medications, and a bite that doesn’t meet evenly. Signs to watch for:
- Waking up with a sore jaw, tight face muscles or a headache
- Teeth that look flat, chipped or shorter than before
- Sensitive teeth or cracked fillings
- A partner hearing you grind at night
What can you do for teeth grinding? There’s no single way to fix teeth grinding. A night guard protects your teeth, but it doesn’t stop the habit on its own. Teeth grinding relief often comes from a few changes together: cutting back on caffeine and alcohol in the evening, a regular bedtime, relaxing your jaw during the day, and treating snoring or sleep apnea if you have them.
If grinding has chipped or cracked a tooth, or your jaw is locked or very painful, call us and we’ll see you as soon as we can. For severe or ongoing jaw joint problems, we’ll refer you for further care.
Night Guards for Adults, Teens and Kids
Grinding shows up at different ages for different reasons.
- Adults: stress and poor sleep are the most common causes. A guard protects natural teeth and dental work such as crowns and veneers.
- Teens: grinding can start during exams or busy seasons. We check whether it’s temporary or needs a guard.
- Children: many kids grind their baby teeth and grow out of it. We usually watch and check wear at each visit rather than make a guard right away.
We check for signs of grinding at every checkup, so wear is often caught before it causes pain or damage.
