An occlusal splint — often called a bite guard or night guard — is a custom-made appliance worn over the upper or lower teeth to manage the effects of clenching and grinding. It separates the teeth, spreads biting forces more evenly and encourages the chewing muscles to relax, which for many people reduces jaw pain, morning tightness and the headaches that go with them. It also protects teeth and existing dental work from further wear and fracture. Splint therapy is non-invasive and reversible, which is why it is usually one of the first steps in treating a temporomandibular disorder.
Is this treatment right for you?
Suitable for: adults who clench or grind their teeth, wake with a tight or aching jaw, have muscle-related jaw pain or headaches, or show tooth wear that is progressing.
Less ideal if: your jaw is currently locked, you have untreated tooth decay, gum disease or an active dental infection, or your pain has a cause outside the jaw joint and chewing muscles — each of which needs to be addressed first.
Suitability can only be confirmed by a qualified clinician after assessing you, which is why every plan begins with a free, personalised review rather than a fixed promise.
Benefits & risks
A balanced view matters more than a sales pitch. Weigh both sides and discuss them with a clinician before deciding.
Potential benefits
- Reduces jaw and muscle pain for many people who clench or grind
- Protects teeth, crowns, veneers and implants from further wear and fracture
- Non-invasive and fully reversible — nothing is done to the teeth or joint
- Often eases the morning headaches and temple tightness linked to night-time clenching
- Can be combined with physiotherapy, habit change and, where needed, other TMJ treatments
- Custom-made and adjusted to your bite rather than bought off the shelf
Risks & considerations
- Tooth or gum tenderness in the first days of wear, which usually settles
- Increased saliva, dry mouth or altered speech while you get used to the appliance
- Bite changes if a splint is worn continuously or not reviewed and adjusted
- Poor results if the splint is not worn as prescribed, or is worn over untreated dental problems
- Symptoms may improve only partly, or return when the splint is stopped
- The appliance can crack or wear out and will eventually need replacing
Am I a candidate?
- You clench or grind your teeth, or have muscle-related jaw pain and headaches
- Your teeth and gums are healthy, or any dental problems have been treated first
- You are able to wear and clean an appliance consistently, usually overnight
- You understand that a splint manages the effects of clenching rather than curing the habit
- You are willing to attend a review so the splint can be checked and adjusted
Only a qualified clinician can confirm suitability after a personal assessment.
Process & recovery
A splint is made from impressions or a digital scan of your teeth, together with a record of how your teeth meet, and is then produced in a dental laboratory in hard acrylic or a softer material depending on the design chosen. At the fitting appointment the splint is adjusted so that it seats comfortably and the biting contacts are even, and you are shown how to insert, remove and clean it. Most splints are worn overnight, although some plans include daytime wear during a flare. Comfort usually settles within one to two weeks, and the splint needs periodic review because the fit and the bite contacts change over time. Risks are limited but real: temporary tooth tenderness, increased saliva, altered speech at first and — with an ill-fitting or unreviewed splint — changes to the bite.
What an occlusal splint does
An occlusal splint is a precision-made appliance that sits over the biting surfaces of the upper or lower teeth. Its job is not to stop you clenching, but to change what happens when you do. By separating the teeth it removes the interlocking contacts that encourage heavy grinding; by presenting an even biting surface it spreads force across many teeth rather than a few; and by holding the jaw in a comfortable position it gives the chewing muscles a chance to settle. The result, for many people, is less muscle pain, less morning tightness and fewer of the headaches that come from a night of clenching.
The second job is mechanical protection. Grinding wears enamel, chips edges and can fracture crowns, veneers and implant restorations. A splint takes that wear instead of the teeth, and is far easier and cheaper to replace than the dental work underneath it.
Types of splint
| Type | Typical use | Notes |
|---|---|---|
| Hard acrylic full-coverage splint | Clenching and grinding, muscle-related jaw pain | The most commonly used design; durable and adjustable |
| Soft or dual-laminate splint | Short-term protection, some grinders who cannot tolerate hard acrylic | More comfortable at first but wears faster; not suitable for everyone |
| Anterior repositioning splint | Selected joint problems where the disc catches | Used for specific diagnoses and requires close review |
Which design is appropriate depends on your diagnosis, your bite and how heavily you grind. Full-coverage splints are generally preferred because partial-coverage appliances can allow unopposed teeth to move.
What happens at each stage
Assessment
The treating dentist examines your teeth, bite, jaw joints and chewing muscles, and reviews any imaging. Active decay, gum disease or a broken tooth is treated before a splint is made, because an appliance fitted over an untreated problem will not solve it.
Impressions or digital scan
Records are taken of the upper and lower teeth and of how they meet. Accuracy at this stage determines how well the finished splint fits, and a digital scan is often more comfortable than conventional impression material.
Fitting and adjustment
The finished splint is tried in, and the biting contacts are refined with fine adjustments until the load is spread evenly. You are shown how to insert, remove and clean it, and given a wear schedule. A short review a day or two later allows any pressure points to be relieved once you have slept in it.
Recovery and settling in
There is no recovery in the surgical sense — you can eat and speak normally as soon as the splint is out. The first nights are the adjustment period: the appliance feels bulky, saliva increases, and some people find their teeth feel slightly tender in the morning. These effects usually settle within one to two weeks. Persistent tenderness, a splint that rocks, or the sense that your teeth no longer meet properly after removal are all reasons to have it checked rather than to persevere.
Splints need review. Teeth move, restorations change, and the appliance itself wears, so the biting contacts that were even at fitting will not stay even indefinitely. A yearly check with your own dentist alongside your routine examination is a sensible minimum.
Having splint therapy in Türkiye
As a medical travel facilitator, we coordinate splint therapy at accredited, Ministry of Health–authorised partner clinics in Türkiye. Before you travel, your symptoms and any dental records are reviewed so the treating dentist can advise whether a splint is the right first step — and, just as importantly, whether something else should be dealt with first.
Packages are all-inclusive and transparent, typically covering assessment, the appliance, hotel accommodation, airport and clinic transfers and an English-speaking coordinator at every appointment. Because a splint is made in a laboratory, the timing is planned around production and fitting, with an adjustment appointment before you fly home — see your patient journey for how a typical visit is organised, and our TMJ treatment overview for how splint therapy fits alongside the other options.

Frequently asked questions
Is an occlusal splint the same as a shop-bought mouthguard? +
No. A shop-bought guard is a generic shape moulded roughly to the teeth, whereas an occlusal splint is made from an impression or digital scan of your own teeth and adjusted so the biting contacts are even. That adjustment is a large part of how the splint works, and it is also what protects the bite. Poorly fitting appliances can make symptoms worse rather than better.
How long do I need to wear it? +
Most splints are worn overnight, and many people continue long term because the underlying clenching habit tends to persist. Some plans include short periods of daytime wear during a flare. Continuous day-and-night wear is generally avoided because it can change the bite. The treating dentist will set out a wear schedule and review interval for your case.
Will a splint stop me grinding my teeth? +
Not usually. A splint manages the consequences of grinding — protecting the teeth and reducing the load on the joints and muscles — rather than stopping the habit itself. Stress, sleep quality and daytime clenching habits all contribute, which is why splint therapy is often combined with physiotherapy and habit advice.
How long does a splint last? +
It varies with the material, the design and how heavily you grind. Hard acrylic splints often last several years, while softer appliances can wear through more quickly, sometimes within a year in heavy grinders. Cracking, thinning or a change in fit are signs that a splint needs replacing.
How long do I need to stay in Türkiye? +
A stay of around three to five days is typically enough for the assessment, the impressions or scan, laboratory production and the fitting appointment, with time for an adjustment before you fly home. Your personalised plan confirms the exact schedule.
How do I look after the splint? +
Rinse and brush it with a soft brush and cool water after each use, store it dry in its case, and keep it away from hot water, which can distort it. Cleaning tablets designed for dental appliances can be used as advised. Take it to your dental check-ups so it can be inspected along with your teeth.
When will I notice a difference? +
Some people notice less morning tightness within one to two weeks, while muscle pain and headaches often ease more gradually over several weeks. Improvement is rarely linear, and symptoms can fluctuate. If there is no change after a reasonable trial period, the treating dentist will reassess rather than simply continuing.
