Protect yourself against the harmful effects of teeth grind


What is a nightguard?

You must wear your nightguard every night for it to be effective

A nightguard is a dental prosthesis that sits on top of your teeth to protect them against the harmful effects of teeth grinding. You must wear your nightguard every night for it to be effective. Your nightguard separates your upper and lower teeth when you are clenching. As a result, your bite forces are transferred to the nightguard which prevents your teeth from getting damaged as a result of teeth grinding.

Night time grinding is much more common than you think. A vast majority of us grind our teeth at nights without even knowing. This is mostly the result of daytime stress which causes us to subconsciously grind our teeth while asleep. Wearing a nightguard helps protect your teeth and jaws when you are sleeping. Contact your local dentist to learn more about nightguards and to see if you are a good candidate for wearing one.

Why do I need to wear a nightguard?

Nightguards protect your teeth against wear-and-tear caused by teeth grinding

Nightguards protect your teeth against wear-and-tear damage caused by night time teeth grinding. Ignoring your teeth grinding habit can cause lots of dental and skeletal problems. Your teeth could break, which would require fillings or crowns. You could even break your tooth so bad that it may need a root canal or you might even lose the tooth! Heavy teeth grinders also damage their TMJ which causes headaches, migraines, and tension pain in the head and neck region. Wearing a nightguard protects your teeth, bite, as well as you TMJ. This is an investment in your healthy that is definitely worth it and pays for itself.

If you believe that you're grind your teeth then you may have to wear a nightguard. Heavy grinders and those with existing damage to their teeth should consider wearing a custom nightguard. Schedule your consult with your dentist to look for symptoms of teeth grinding. If it is determined that you are indeed a grinder, then your dentist will fabricate a nightguard for you.

When do I need to wear a custom nightguard?

There are two types of nightguards: (a) over-the-counter nightguards and (b) custom-made nightguards. Over the counter, or OTC, nightguards can be bought at the drug store or online. Just follow the instructions and fit them to your own teeth. On the other hand, custom nightguards are made by your dentist using impressions or scans of your teeth.

So which night guard is best for you? This all depends on how heavily you grind, how long you've been grinding, your symptoms, etc. Your dentist will help you determine which type of nightguard is best to protect your teeth. Generally speaking, custom nightguards are much more effective and better at protecting your teeth as compared to OTC night guards. However, they are much more expensive as well. Here are some examples of cases where you should definitely consider wearing a custom nightguard instead of an over-the-counter version:

Heavy tooth grinders

Heavy tooth grinders should only wear a custom nightguard

Heavy tooth grinders should have their dentist fabricate a custom nightguard for them. Only a custom nightguard is strong enough to protect your teeth against symptoms of severe tooth grinding. Over-the-counter nightguards are not as effective for heavy tooth grinders. Your jaw forces will destroy the over-the-counter nightguard in no time and render it ineffective. Custom nightguards come in different thickness. They are customized to protect your teeth and TMJ and best accommodate your needs.

Those with extensive existing dental work

Wearing a custom nightguard reduces the wear onto the opposing natural teeth

If you have lots of existing dental restorations in your mouth, then we recommend that you wear a custom nightguard. For instance, if you have several crowns, dental implants, and bridge work in your mouth, then you need a well-made, high-quality nightguard. Many dentists include a custom nightguard as part of your treatment when performing extensive dental rehabilitation or offer it at a discount. Wearing your custom nightguard protects expensive dental work over time. Additionally, wearing a nightguard reduces the wear that your existing crowns exert onto the opposing natural teeth. As a result, wearing a custom nightguard protects BOTH your natural teeth and your existing dental restorations.

Those suffering from migraines, frequent headaches and TMJ pain

Wearing a custom night guard can significantly reduce, or even eliminate, head and neck pain

Wearing a custom nightguard does more than protect your teeth, it also protects your TMJ. This significantly reduces, or even eliminates, head and neck pain caused by teeth grinding. You can also reduce tension headaches, migraines, and neck stiffness by regularly wearing your custom nightguard. Those who experience frequent headaches of at least two to four episodes per month, should seriously look into wearing a custom nightguard.

Amalgam (silver filling)

Material used to fill dental cavities. Amalgam is silver colored and contains Mercury. As a filling material, Amalgam is durable and effective. However, there are some concerns about the safety of using Mercury to restore teeth.

Bicuspid tooth

Refer to premolar tooth please.

Canine tooth (cuspid or eye tooth)

A strong, pointed tooth with a single cusp used to direct other teeth as we chew side-to-side. Canine teeth are very strong and typically outlast all other teeth as we age. We have 4 total canines, teeth numbers: 6, 11, 22 and 27.

Cavity (decay)

A hole inside a tooth created by harmful cavity bugs. Dental cavities can cause slight tooth sensitivity, particularly to cold and sweets. They can also be asymptomatic. If left untreated, dental cavities infiltrate the tooth pulp and cause abscess and infection.

Composite resin (white filling)

Material used to fill dental cavities and broken teeth. Composite resin is safe, effective and matches your tooth color. Cosmetic dentists prefer using composite resins to other filling restoration material due to their natural appearance.

Crown (cap)

A large restoration that replaces the majority of your tooth structure above the gum line. Crowns are used to fix teeth which can no longer be salvaged with a simple filling. Crowns are typically made from gold, porcelain-fused-to-metal or ceramic material.

Deep cleaning (scaling & root planning)

A type of dental cleaning which focuses on removing plaque and tartar underneath your gum line. Deep cleanings are used to treat gum disease. Most deep cleanings are performed in multiple sessions and often times require anesthesia.

The middle portion of your tooth which is located above the pulp and underneath the enamel. Unlike enamel, dentin has nerve endings which makes it sensitive to tooth decay.


Removable, false teeth used to replace your missing natural teeth. Dentures are made from pink and white acrylic. The pink portion secures your dentures in place and the white segment replaces your missing teeth. There are many different types of dentures including full dentures and partial dentures.


The very hard outer portion of your tooth. In fact, enamel is the hardest tissue found in our bodies. Enamel protects your tooth from cavities and provides it with the strength to cut and chew food.


Material used by dentists to replace missing tooth structure. Fillings are used to fix dental cavities and broken teeth. Fillings are made from gold (mostly obsolete), Amalgam (silver filling) or composite resin (white filling).

Full Denture (Complete denture)

A set of false teeth which replaces all of your teeth in one arch. Full dentures are held in place by the suction they provide against your gum tissue. Full dentures are typically made from pink and white acrylic.


The earlier stage of gum disease. Gingivitis is characterized by bleeding gums, bad breath and minor tooth sensitivity. If left untreated, gingivitis progresses to the more advanced stage of gum disease known as periodontitis.

Gum Disease (Periodontal disease)

Disease of the gums and jaw bone. Gum disease is caused by spread of harmful bacteria to your gum and jaw bone. Gum disease causes bleeding gums, bone loss and tooth loss. Gum disease is categorized as gingivitis and periodontitis.
