Do you often wake up with a sore jaw and aching facial muscles? Do your teeth feel loose in the morning? If so, you may be grinding your teeth or clenching your jaw — during sleep or even during the day. Teeth grinding can seriously affect your oral health, but it is very treatable. Here’s what you need to know.
What Are Teeth Grinding and Clenching?
Teeth grinding — clinically known as bruxism — is a condition in which a person grinds their teeth excessively, either while awake or asleep. The American Academy of Oral Medicine defines two types:
- Daytime bruxism — typically occurs during periods of stress, intense concentration, or anger, usually without the person being aware of it.
- Sleep bruxism — an involuntary form that occurs during sleep. Research links it to increased brain activity during sleep, with stress, alcohol, and certain antidepressant medications as contributing factors.
Clenching, by contrast, is holding the teeth together and tightening the jaw for prolonged periods. It’s generally less damaging than grinding, but left untreated it can still cause significant harm.
What Are the Consequences?
- Tooth wear — grinding wears away the protective enamel layer, leading to sensitivity and cavities.
- Difficult chewing and impaired digestion — prolonged grinding flattens the biting surfaces, so food isn’t broken down efficiently.
- Temporomandibular joint (TMJ) disorders — sustained pressure on the jaw joints can cause painful or limited mouth opening, clicking or popping sounds, and even joint dislocation.
- Tooth misalignment — bruxism can gradually shift teeth out of alignment.
How Can I Stop Grinding My Teeth?
Managing bruxism starts with identifying the underlying cause.
Daytime Bruxism
Daytime grinding usually responds well to behavioral changes — limiting alcohol and tobacco, eating a healthy diet, and reducing sources of stress. In some cases, working with a mental health professional on the underlying stressors helps.
Sleep Bruxism
Sleep bruxism is diagnosed through a detailed history and clinical exam — the classic sign is waking up with enlarged, sore facial muscles and painful jaws. Treatment options include:
- Nightguards — an appliance worn over the teeth during sleep that protects them from grinding damage and relieves jaw and muscle pain.
- Medication — a muscle relaxant taken before sleep can prevent morning muscle soreness.
- Stress relief — when stress is the primary driver, addressing it directly is part of the treatment plan.
Are Nightguards Necessary?
A nightguard (also called a bite guard) is a plastic appliance that covers the teeth and protects them from wear. It’s typically needed for sleep bruxism, where behavioral changes alone aren’t enough. Your dentist will recommend one after a thorough exam.
Do I Need a Custom Nightguard From a Dentist?
Nightguards come in two types. Stock “boil-and-bite” guards from the store are cheaper, but because they aren’t made precisely to your teeth, they can do more harm than good. A custom nightguard made by your dentist fits exactly, protects against wear, and relieves pressure on the jaw joints — the better choice if you’re dealing with bruxism.
Teeth grinding is a serious condition that deserves prompt treatment — and many people only learn they have it from a partner or at a dental checkup.
