Bruxism (Teeth Grinding) — Causes, Consequences, and Treatment
Insights from an English-Speaking Dentist in Çankaya, Ankara
Do you wake up with a sore jaw, a dull headache, or notice that your teeth feel increasingly sensitive? These can be quiet signals of bruxism — the habitual grinding or clenching of teeth — a condition that affects a significant proportion of adults and is frequently unrecognised for years. Because bruxism most commonly occurs during sleep, many people are entirely unaware of it until the dental consequences become visible. This article explains what bruxism is, why it matters, and what can be done about it.

What Is Bruxism?
Bruxism is the involuntary grinding, clenching, or gnashing of the teeth. It is classified into two types based on when it occurs: awake bruxism, which happens during waking hours and is typically associated with stress, concentration, or emotional tension; and sleep bruxism, which occurs during sleep and is classified by the NHS as a sleep-related movement disorder.
Sleep bruxism is the more clinically significant of the two, because the forces generated during sleep can far exceed those produced by normal chewing — sometimes by a factor of ten. The person is entirely unconscious of the activity and has no opportunity to moderate it. Sleep bruxism can also occur alongside other sleep disorders, including snoring and obstructive sleep apnoea.
Research published in peer-reviewed literature estimates that bruxism affects between 8 and 31 percent of the adult population, with considerable variation depending on how the condition is defined and measured. It is not a rare problem — but it is commonly unrecognised.
What Causes It?
Bruxism is rarely caused by a single factor. In most cases, multiple contributing elements are present simultaneously, which is one reason it can be difficult to eliminate entirely rather than simply manage.
Stress and anxiety are the most consistently identified triggers. The relationship between psychological tension and jaw clenching is well established — many people clench during periods of intense concentration or emotional stress even when awake, without being fully aware of it. During sleep, this same tendency can manifest as grinding or clenching without any conscious trigger.
Sleep disorders — particularly obstructive sleep apnoea — are associated with a significantly higher prevalence of sleep bruxism. The precise mechanism is not fully understood, but the relationship is clinically relevant: patients presenting with bruxism should be assessed for sleep-disordered breathing if other indicators are present.
Certain medications are known to increase the risk of bruxism, most notably some antidepressants — particularly SSRIs. Caffeine and alcohol consumption, especially close to sleep, have also been associated with increased bruxism activity during the night. Malocclusion — an irregular bite caused by misalignment of the teeth or jaw — may contribute in some cases, though the evidence for this as a primary cause is less consistent than for the factors above. A genetic predisposition has also been identified.
Warning Signs and Symptoms
Because sleep bruxism occurs unconsciously, many patients first become aware of it through secondary symptoms rather than the grinding itself. The most common presentation is waking with jaw, face, or neck pain — reflecting the muscular effort expended during the night. Headaches on waking, particularly across the temples, are another frequent complaint.
Dental changes are often the first clinically visible sign. Enamel wear produces characteristic flat, polished surfaces on the biting edges of the teeth, making them appear shorter than they once were. Increased sensitivity — particularly to temperature — follows as the enamel thins and the underlying dentine becomes less well-insulated. Chipping of the enamel edges and fractures of existing restorations are also common findings.
Gum recession can occur in bruxism patients, as the lateral forces generated during grinding place stress on the supporting structures of the teeth as well as the crowns. Some patients report a sensation of ear pain or fullness — a referred symptom from the temporomandibular joint and the muscles of mastication, which are in close proximity to the ear canal. A sleeping partner hearing grinding sounds during the night is often the most immediate prompt for a patient to seek assessment.
What Happens If It Goes Untreated?
Untreated bruxism produces progressive and cumulative damage. The trajectory follows a broadly predictable pattern, though the rate of progression varies considerably between individuals depending on the intensity and frequency of grinding episodes.
In the early stages, enamel wear is the primary consequence. As the enamel layer thins, the teeth become increasingly sensitive and more vulnerable to decay — the enamel’s protective function is diminished as it becomes thinner. The visual change — teeth appearing flatter and shorter — is often the first change patients notice themselves.
As wear progresses, fractures become more likely. Teeth that have been significantly thinned by bruxism are structurally weaker and more prone to chipping or cracking under normal biting forces. Existing restorations — fillings, crowns, and veneers — are also subject to accelerated wear and fracture in patients with untreated bruxism, which compromises their longevity significantly.
The temporomandibular joint (TMJ) — the hinge joint connecting the jaw to the skull — is placed under chronic stress in bruxism patients. Over time, this can result in temporomandibular disorder (TMD): a condition characterised by jaw pain, clicking or popping sounds on opening, limited mouth opening, and in severe cases, jaw locking. TMD can be difficult and time-consuming to treat once established, and some of the structural changes involved are irreversible.
How Is It Diagnosed?
In most cases, bruxism is identified through a clinical dental examination. The dentist assesses the wear patterns on the tooth surfaces, looks for characteristic flattening of the biting edges, evaluates the condition of the enamel, and checks for tenderness in the jaw muscles and temporomandibular joint. The patient’s reported symptoms — morning jaw pain, headaches, sensitivity — contribute to the clinical picture.
In cases where sleep apnoea is suspected, or where the diagnosis of sleep bruxism needs to be formally confirmed, polysomnography — a comprehensive sleep study — may be used. This records jaw muscle activity during sleep and can distinguish sleep bruxism from other jaw movement disorders. However, for the majority of patients, a dental examination and clinical history are sufficient to establish the diagnosis and proceed with protective treatment.
Treatment Options
There is currently no single treatment that eliminates bruxism entirely in all patients. The aims of management are to protect the teeth and jaw from further damage, reduce associated pain and muscle tension, and address contributing factors where possible.
Occlusal Splint (Night Guard)
A custom-made occlusal splint — commonly called a night guard — is the most widely used and well-supported treatment for sleep bruxism. The device is worn over the teeth during sleep and creates a barrier between the upper and lower dental arches, preventing direct tooth-to-tooth contact. It does not stop the grinding behaviour, but it protects the enamel surfaces and reduces the load transmitted to the temporomandibular joint. A properly fitted splint is fabricated from impressions of the patient’s teeth and is quite different from over-the-counter boil-and-bite devices, which provide substantially less precise fit and protection.
Stress Management
For patients in whom stress and anxiety are identified as primary contributors, psychological approaches — including cognitive behavioural therapy, relaxation techniques, and biofeedback — can meaningfully reduce bruxism activity. These are most effective when used alongside dental protective measures rather than instead of them.
Physiotherapy
Jaw physiotherapy — including massage, stretching exercises, and manual therapy — can be helpful for patients with significant muscle tension and TMJ symptoms. It addresses the muscular consequences of bruxism and can reduce pain, improve range of motion, and complement other treatments.
Botulinum Toxin (Botox) Injections
Injections of botulinum toxin into the masseter muscles — the large muscles on either side of the jaw responsible for chewing — can reduce the force of jaw clenching by partially relaxing these muscles. The effect is temporary (typically three to six months) and the procedure needs to be repeated for sustained benefit. It is most commonly used for patients with significant muscle hypertrophy or severe TMJ symptoms that have not responded adequately to splint therapy alone.
Orthodontic Treatment
Where malocclusion is a contributing factor, correcting the bite through orthodontic treatment may reduce bruxism activity. This is not a universal solution — the relationship between occlusion and bruxism is complex and not fully established — but in selected cases it forms part of a broader management plan.
Restorative Treatment
When significant tooth structure has already been lost to bruxism, restorative treatment — rebuilding worn surfaces with composite, ceramic onlays, or crowns — may be necessary to restore both function and aesthetics. This is typically planned after the bruxism is under active management, so that the new restorations are not immediately subject to the same forces that caused the original damage.
When to See a Dentist
Bruxism does not resolve on its own. If the pattern is established, the damage accumulates — and the consequences become progressively more difficult and more costly to address. Early assessment and protective management are always preferable to waiting until symptoms become severe.
Seek a dental assessment if you regularly wake with jaw pain or headaches, if you have noticed that your teeth appear to be wearing down or becoming more sensitive, if you have chipped or fractured teeth without an obvious traumatic cause, if a partner has reported hearing grinding sounds during the night, or if you experience clicking, pain, or limited movement in the jaw joint.

Frequently Asked Questions
Can bruxism go away on its own?
In children, bruxism often resolves without intervention as the dentition develops. In adults, established bruxism does not typically resolve on its own and tends to cause progressive damage if unmanaged. Early protective measures prevent the accumulation of irreversible wear.
Will a night guard stop me from grinding?
A night guard does not eliminate the grinding behaviour — it protects the teeth and jaw from its consequences. Most patients find it also reduces morning jaw pain and headaches significantly, as the muscles work against a softer surface than enamel.
Is a custom night guard better than an over-the-counter one?
Considerably. A custom-fabricated splint is made from precise impressions of the patient’s teeth, provides accurate occlusal contact, and is made from appropriate materials for long-term use. Over-the-counter boil-and-bite devices offer an approximate fit and are generally not suitable for sustained nightly wear.
Can bruxism damage dental implants or crowns?
Yes. Implants, crowns, veneers, and other restorations are all subject to the same excessive forces as natural teeth in bruxism patients. A night guard is particularly important for patients who have had significant restorative or cosmetic dental work, as it protects the investment as well as the remaining natural teeth.
My antidepressant medication seems to have made my grinding worse — what should I do?
This is a recognised side effect of certain antidepressants, particularly SSRIs. Raise it with your prescribing clinician — in some cases, a medication adjustment or switch can reduce bruxism activity. In the meantime, a night guard provides protection for the teeth while the medication situation is reviewed.
I am visiting Ankara — can I get a night guard made during my trip?
In most cases, yes. A custom night guard requires impressions at the first appointment and fitting at a follow-up appointment. Depending on laboratory turnaround, both can often be accommodated within a planned visit. Contact us before travelling so we can schedule appropriately.
