What bruxism is and when it needs treatment
Bruxism means grinding or clenching the teeth. It can happen during the day, without the person noticing, or during sleep. According to the NHS, stress and anxiety are its most common cause, and treatment is not always necessary. The decision depends on whether there is damage: worn or broken teeth, sensitivity, pain in the jaw, face or ear, or disturbed sleep.
That is the practical test that separates a mild habit from a problem worth a visit. Occasional bruxism, with no wear or pain, can be monitored at routine checkups, such as a regular dental cleaning. Wear that keeps progressing, on the other hand, does not reverse by itself, because enamel does not regenerate.
Signs worth recognizing
People who grind at night rarely notice it, which is why indirect signs matter. The NHS lists the most common ones and recommends seeing a dentist in several situations. This checklist combines both:
- Worn, chipped or broken teeth, with sensitivity and, in some cases, loss of fillings.
- Jaw pain, which the NHS says can lead to a temporomandibular disorder.
- Headache or earache, often on waking.
- Disturbed sleep, or a partner who hears the grinding at night.
- Pain when chewing or difficulty chewing properly. The Dental Life website links this to bite problems that cause pain in the temporomandibular joint.
- Suspicion in a child. The NHS says a visit is also reasonable when a parent is worried about a child grinding their teeth.
With one or more of these signs, a dental evaluation can confirm whether bruxism is present, measure the wear and rule out other causes of pain. No sign alone establishes the diagnosis.
What causes it
The NHS attributes bruxism to several factors, which often overlap:
| Factor | What the NHS says |
|---|---|
| Stress and anxiety | The most common cause. |
| Sleep problems | Snoring and sleep apnea. |
| Medications | Some for sleep, depression or anxiety. |
| Habits | Smoking, high alcohol or caffeine intake. |
Source: NHS, Teeth grinding (bruxism). The list summarizes the factors the page mentions.
This list explains why the approach is not always limited to the mouth. A family doctor can advise on stress, sleep or medications, while the dentist protects and repairs the teeth.
Treatment options and what the evidence says
The published systematic reviews are cautious. The most cited one on splints is a 2007 Cochrane review: it included five studies, concluded that the evidence was insufficient to say occlusal splints are effective for sleep bruxism, and noted they might help reduce tooth wear. Its authors called for better-designed trials. That review is almost twenty years old and no Cochrane update was located.
Later work adds nuance. A 2022 systematic review on managing sleep bruxism in adults found that splint therapy tended to reduce episodes, with no significant differences between splint types. Another 2024 review, with 15 included studies out of 808 screened, concluded that occlusal splint therapy is a viable approach, with better results for adjustable splints, and warned that possible adverse effects should be assessed case by case.
| Option | What it involves | What the source says |
|---|---|---|
| Night guard or splint | A device worn at night to protect the teeth. | NHS: a dentist may recommend one. Cochrane 2007: insufficient evidence on effectiveness, possible help against wear. 2024 review: viable approach. |
| Stress management | Relaxation, breathing and better sleep habits. | NHS: self-care options and a medical consultation. |
| Cognitive behavioral therapy | A targeted psychological intervention. | 2022 review: its benefits are not well supported. |
| Biofeedback and drugs | Interventions used in clinical studies. | 2022 review: reductions in specific parameters, with side effects. |
| Review of habits | Smoking, alcohol, caffeine. | NHS: factors that may contribute. |
| Occlusal adjustment and rehabilitation | Correcting the bite and repairing wear. | According to the Dental Life website, part of its oral rehabilitation service. |
Sources: NHS, Cochrane (CD005514) and the 2022 and 2024 reviews linked above. The table does not rank the options: the choice depends on the diagnosis.
In practice the sources agree on one point: a splint protects the teeth but does not remove the cause by itself. That is why it is often combined with managing the factors in the previous section.
What a dentist does about bruxism
Dental Life Panamá, in Costa del Este, describes on its oral rehabilitation page an occlusion block that includes temporomandibular joint diagnosis, bruxism treatment, occlusal splints and occlusal adjustment. Among the cases where, according to that page, rehabilitation is needed are severe tooth wear caused by bruxism and bite problems with jaw pain.
The same page mentions study models, occlusal analysis and virtual articulators, which simulate jaw movements to achieve an optimal bite. Among the benefits it cites are relief of temporomandibular joint pain and prevention of future dental problems. When wear already compromises the structure of the teeth, repair falls under the comprehensive plan described in Radar’s guide to full mouth rehabilitation. When the motive is cosmetic, wear also shapes the decision on dental veneers.
Dental Life Panamá presents bruxism treatment, occlusal splints and occlusal adjustment on its website as part of its oral rehabilitation service. The service page details the diagnostic process and the cases where it is indicated.
What to ask at the evaluation
A visit for suspected bruxism is more useful with specific questions. This list is based on the points in the sources cited:
- Is there visible wear? It helps if the dentist shows it and records it to compare at later checkups.
- Is the temporomandibular joint involved? Joint diagnosis is among the clinic’s occlusion services.
- Is a splint justified? If so, which type, how many hours it is worn and how often it is reviewed. The 2022 review found no significant differences between splint types, while the 2024 one reports better results with adjustable splints; the 2024 review asks for adverse effects to be assessed individually.
- Are there factors to address outside the dental office? Stress, sleep, medications, tobacco, alcohol or caffeine.
- Do any teeth need repair? The exact quote for any treatment is given after the evaluation.

Frequently asked questions
What is bruxism?
Bruxism is grinding or clenching the teeth, awake or asleep. According to the NHS, it is often related to stress or anxiety and can cause worn teeth, jaw pain, headaches and disturbed sleep.
How can someone tell if they have bruxism?
The most common signs are worn or sensitive teeth, jaw pain, headache or earache on waking and a partner who hears the grinding. Only a dental evaluation confirms the diagnosis.
Does a night guard cure bruxism?
There is no solid evidence that a night guard eliminates bruxism. It protects the teeth from wear and, according to 2022 and 2024 reviews, tends to reduce episodes, but the 2007 Cochrane review found the evidence on its effectiveness insufficient.
When should someone see a dentist about bruxism?
When there is tooth damage or sensitivity, pain in the jaw, face or ear, or when someone hears the grinding during sleep. The NHS also includes concern about a child who grinds their teeth.
Who treats bruxism in Panama?
Diagnosis and the night guard fall to the dentist. According to its website, Dental Life Panamá, in Costa del Este, includes bruxism treatment and occlusal splints in its oral rehabilitation service.
