Bruxism Treatment and Night Splints in Ukraine

Bruxism is repetitive jaw muscle activity: clenching the jaws or grinding the teeth together. There are two forms, depending on the time of day, and they are not the same thing. Sleep bruxism is rhythmic muscle contractions during brief night-time arousals, which the patient is usually unaware of; awake bruxism is mostly quiet clenching of the jaws during the day: at work, at the wheel, in a tense conversation. Their mechanisms differ, and so does the approach: the night-time form is managed with an appliance, while the daytime form is mostly a habit to unlearn.

An important point that often gets lost in the dental chair: in a person with no other health problems, the international consensus definition treats bruxism not as a disease but as a motor phenomenon. It becomes something to treat when consequences appear: enamel wear, chipped restorations, muscle pain and fatigue, headache in the temples in the morning. So the dentist's question is not "do you grind your teeth?" but "what has it already done to your teeth and muscles?"

The damage shows on the teeth before the patient suspects anything. Enamel wears into flat facets that match exactly on the upper and lower teeth when they close; chips and a translucent edge appear on the incisors, and shiny flat areas and islands of exposed dentine on the chewing surfaces. Fillings crack and fall out, the ceramic of veneers and crowns chips, and sometimes the tooth itself cracks. For patients with implants, overload is an extra risk: an implant is fused directly with the bone, has no ligament and does not cushion chewing pressure the way a natural tooth does, so the effects of grinding show up first on prosthetic restorations.

Not everyone needs a custom splint, and it is worth saying so plainly. It is prescribed when there is evidence of active damage: fresh wear facets, repeated chipping of restorations, exposed dentine, muscle pain in the morning, and also when costly prosthetic work or veneers are planned and need protecting from the same load. If there are no signs of wear, no pain and no reports of night-time grinding from those close to you, an appliance is not needed: a photographic record and a check-up are enough. A splint is not made for children with primary or mixed dentition either: grinding at this age is common and mostly passes by itself, while a rigid appliance on growing jaws can interfere with the eruption of teeth.

One more caveat: not all tooth wear is caused by grinding. Acid erosion from reflux or frequent acidic drinks, and abrasion from a hard toothbrush with abrasive toothpaste, can look very similar; in these cases a splint is pointless, because it protects against mechanical friction, not against acid. Only an in-person examination with a photographic record and jaw models can show what is actually damaging the enamel. MediUkraine is a treatment search and coordination service, not a clinic: we match you with a clinic and a suitably specialised doctor, arrange the dates and support you throughout, while diagnosis and treatment decisions are made by the doctor after an examination.

Bruxism is diagnosed in steps, and it helps to know this in advance so you do not expect more from an examination than it can deliver. The international approach distinguishes three levels of certainty: possible bruxism, when there is only the account of the patient or those close to them; probable, when findings from a clinical examination are added to that account; and definite, when jaw muscle activity has been recorded by an instrument. Most patients are treated at the second level, and this is normal practice: instrumental recording is not needed to justify a splint, only to answer specific questions.

The clinical examination gives the most information. The dentist looks for wear facets that match on the upper and lower teeth when they close, enamel cracks, chipped incisor edges and ceramics, exposed dentine on the cusps, a white line on the inside of the cheek at the level where the teeth meet, and tooth marks along the edge of the tongue; separately, the dentist assesses the bulk of the masseter muscle, its firmness and tenderness on palpation. All of this is recorded in a photographic record and on jaw models. Without such a reference point it is impossible to say a year later whether the wear is progressing or standing still, and that is exactly what determines whether active intervention is needed.

The next step is to establish whether grinding really is the cause of the wear. A similar picture is produced by erosion: acid from fizzy drinks, citrus fruit and wine, as well as stomach contents coming up with reflux, dissolve the enamel; the surface becomes smooth and shiny, with cup-shaped hollows, and fillings begin to stand proud of the tooth. Another cause is abrasion from a hard toothbrush and abrasive toothpastes, which stays near the necks of the teeth. The distinction matters: a splint protects against mechanical friction but does not stop acid, so with untreated reflux the damage will continue underneath it.

Polysomnography with audio and video recording is the only method that records episodes of rhythmic jaw muscle activity during sleep while also showing breathing, blood oxygen saturation and sleep structure. It is not prescribed for everyone, only for specific reasons: suspected breathing disorders during sleep, unusual movements or tongue biting at night, grinding that appears after starting a new medicine, or treatment that has had no effect. Portable electromyography (EMG) devices that you stick onto the muscle at home are cheaper and more convenient, but they do not see breathing, so they do not rule out apnoea.

Bruxism is rarely a purely dental matter, and that is the main reason not to stop at a mouthguard. The daytime form is consistently linked with anxiety, emotional strain and concentration: people clench their jaws at the screen, in traffic, during urgent work. The night-time form is linked with brief arousals during sleep, and it depends more on how sleep is structured than on how the teeth are aligned. Substances and medicines also play a part: smoking, caffeine in the second half of the day, alcohol, and among medicines, SSRI antidepressants and venlafaxine, atomoxetine and psychostimulants. If the grinding appeared a few weeks after starting a new medicine, adjusting the therapy sometimes solves the problem, and that is done by the doctor who prescribed the medicine, not by the dentist.

Sleep apnoea deserves separate attention. Pauses in breathing during sleep are accompanied by brief arousals, and some episodes of grinding coincide with them, so the two conditions often coexist in the same patient. In practice, if a person snores, if those close to them notice pauses in breathing, if daytime sleepiness persists, then sleep screening comes first and an appliance in the mouth only afterwards. The reason is not bureaucracy: in some patients with untreated apnoea an ordinary occlusal splint worsens breathing during sleep, because it changes the position of the lower jaw and the tongue. For such cases there is a separate appliance, a device that moves the lower jaw forward, and it is prescribed together with a sleep specialist, after an assessment, not instead of one.

Now to the splints themselves: there are several kinds, and mixing them up can cost you teeth. A muscle-relaxation splint, also called a stabilisation splint, is a rigid appliance of clear acrylic covering the whole arch with even contacts; this is the main option for an adult patient with signs of wear. A repositioning splint holds the lower jaw in a set position and is used for specific jaw joint indications and for a limited period. A soft silicone mouthguard is attractive for its comfort, but the jaw muscles often take the yielding material as an invitation to chew: in some patients it increases clenching. An anterior bite plane, which covers only the incisors, quickly takes load off the muscles, but with unsupervised wear the side teeth can shift and the bite can change, so it is prescribed under supervision and not for the whole night without monitoring.

Ready-made mouthguards from a pharmacy are a separate issue, and the problem is not the price but the specific ways they can cause harm. A blank that is softened in boiling water and bitten into cannot be fitted so that the contacts are even: in the mouth it rests on a few random points, and those teeth receive a double load. If the appliance does not cover the whole arch, the teeth left outside it have time to over-erupt over months of wear, and the bite changes, which then has to be corrected orthodontically. The material of such mouthguards is usually soft, which works against the patient; nobody calculates the thickness; the seam and edges injure the gums, and the porous surface is hard to clean. Most importantly, the mouthguard muffles the sound and reassures the household, so the check for apnoea, reflux and medicine side effects never happens.

Reversible methods work alongside the splint and cost much less. Daytime clenching responds well to awareness training: you set phone reminders or put stickers on your monitor and each time check a simple rule: lips together, teeth apart, tongue resting gently against the palate. Next comes work on sleep: a consistent bedtime, limiting caffeine after lunch, avoiding alcohol in the evening, winding down before bed. Cognitive behavioural therapy and biofeedback techniques have a limited evidence base specifically as regards the number of grinding episodes, but they are reversible, do not harm the teeth and help with the anxiety that often goes along with the condition.

Dentistry has no medicine that switches bruxism off, and an offer to "take a course of pills" should raise suspicion. Botulinum toxin injections into the jaw muscles reduce the strength of contraction and, in some studies, pain as well, but they do not affect the central mechanism, the effect is temporary, and data on long-term use are limited; this is a method for individual cases of marked muscle pain or hypertrophy, not a first-line treatment. Restoring worn teeth is a separate and often extensive prosthetic job: when bite height has been lost, it is restored in stages, with temporary restorations and a trial period in them. Starting this work before protection is in place makes no sense: new ceramics chip under the same load that destroyed the natural enamel.

The first few nights with a splint almost always feel strange. You may produce more saliva and your speech may change, and in the morning there may be a feeling that the teeth are not meeting the way they used to; this passes within 20–30 minutes of taking the appliance out. Getting used to it usually takes 3–7 days. But if the splint presses on a particular tooth, rubs the gums or falls out at night, do not wait it out: this is a fitting issue that takes a few minutes to fix at an extra visit.

The first check is scheduled after 1–2 weeks, and then roughly every 4–6 weeks during the active stage. This is because as the jaw muscles relax, the lower jaw takes up a slightly different position, and a splint that fitted perfectly a month ago begins to make uneven contact. That is why adjustments are not an extra service but part of the method, and skipping them means wearing an appliance that is no longer working as intended.

Muscle pain is the first to ease. Morning jaw fatigue and tension pain in the temples usually ease within 2–6 weeks if evening habits are changed alongside the splint. The grinding itself, however, may remain: the appliance redistributes the load and takes it on itself but does not switch off the muscle activity, so those close to you may still hear the sound. This is not a sign of failure: the goal is preserved teeth and no pain, not silence at night.

The clearest indicator of the effect is the splint itself. After a few months its surface shows exactly where and how hard the teeth are working: from the depth and position of the marks the dentist assesses the load, and at the same time can see whether the patient wears it at all. The second tool is repeat photos and jaw models after 6–12 months: they are compared with the initial ones to see whether the wear has increased. The comparison is based on measurements and images, not on how things feel.

To be frank about the long-term outlook: bruxism follows a wave-like course. Quiet periods alternate with flare-ups triggered by stress, lack of sleep or a change of medication, and this rhythm cannot be fully predicted. Only a doctor who has examined you can predict the outcome in your case. That is why the splint is usually kept on after the active stage is over, as permanent protection for the teeth rather than a course with an end date.

If after three or four months the pain has not eased or the wear is visibly progressing, the right course is to review the diagnosis rather than keep doing the same thing. At this stage the dentist checks whether a breathing disorder during sleep has been missed, whether this is acid erosion, whether the medication has changed, and whether the source of pain lies outside the jaw muscles. If you live abroad, interim checks can conveniently be done remotely: you keep the photos, examination report and models, and MediUkraine arranges a video consultation with the same doctor if needed.
