Occlusal Guards
The term “occlusal” refers to the surfaces of your teeth that are used for chewing. When you are damaging those surfaces by clenching or grinding your teeth, an occlusal guard may be recommended by your dentist.
Also referred to as a nightguard, bite guard, or bite splint, an occlusal guard is a removable appliance that fits over your upper or lower teeth. It helps prevent damage to your teeth that can be caused by grinding and clenching which is a destructive oral habit also known as bruxism.1
While occlusal guards don’t necessarily stop you from grinding or clenching, they do help protect the tooth surfaces from damage caused by those actions. Occlusal guards can also help alleviate the symptoms associated with bruxism including jaw pain, head and neck muscle pain, tooth wear and fracture, tooth sensitivity, and headaches.
Occlusal guards are similar in appearance to sports mouthguards but are typically less bulky and are made of smoother, thinner plastic.
FAQ
While occasional teeth grinding or clenching should not be a major cause of concern, consistent, long-term bruxism can lead to pain, broken teeth, loss of tooth enamel, and in severe cases – loss of teeth themselves.
Bruxism is a fairly common problem. It is estimated that about 10 percent of adults and as many as 15 percent of children are affected. This grinding and clenching typically occurs at night, but may also be a daytime habit, and most people are unaware they have the problem. Unless your sleep partner complains about the noise, your dentist is usually the first to recognize the damage to your teeth and raise concern.
Some symptoms that may indicate the need for an occlusal guard include:
Teeth clenching and grinding, Jaw pain or stiffness, Fractured or worn-down teeth and dental restorations, Loose teeth, Temperature-sensitive teeth, Headaches, earaches, toothaches in the morning, Facial pain, Disrupted sleep or Sleep partner complains about the noise
There are three common types of occlusal guards used to limit the effects of bruxism. If you have any questions about which type is the best for you, then we recommend speaking with your dentist who will be able to advise.
- Soft nightguard – Used to alleviate symptoms for mild cases of bruxism. They fit comfortably and are usually easy to get used to wearing.
- Dual laminate nightguards – Designed for moderate to severe teeth grinders. They have a soft, comfortable, inner surface and a hard, durable outer surface.
- Hard nightguards – Used for very severe cases of bruxism. They are made from acrylic, are extremely durable and long-lasting, and will need to be custom-fit by a dentist.
Other things to know about occlusal guards
Your occlusal guard is intended to make your mouth feel more comfortable. If it doesn’t, then you may not have the right fit. Your occlusal guard may need to be adjusted after placement, and, if it feels uncomfortable in any way or if you experience any pain, then it’s best to let your dentist know. They’ll be able to help.
Most occlusal guards are worn at night only, but those who grind or clench their teeth during the day may also benefit from daytime wear. If esthetics are a concern, your dentist can make a custom guard for daytime use that is significantly less visible from the front – but may also be less durable than those worn at night.
