Night Guards and Occlusal Splints

A night guard or occlusal splint is a removable dental appliance worn over selected upper or lower teeth to protect teeth and restorations from grinding or clenching forces. Certain designs may also support assessment and management of selected jaw-muscle or temporomandibular-joint symptoms.

At Bourgeois Dental Clinic in Dubai, an appliance is recommended only after evaluating the teeth, gums, bite, restorations, jaw movement, symptoms, medical history, sleep concerns, and possible causes of tooth wear or facial pain. A night guard does not stop all grinding and is not a guaranteed cure for headaches, jaw pain, or temporomandibular disorders.

Who May Benefit From a Night Guard?

Assessment may be appropriate for patients with:

• Visible tooth-wear patterns
• Repeatedly chipped or fractured teeth
• Broken fillings, crowns, or veneers
• Reported night-time grinding
• Daytime clenching
• Jaw-muscle fatigue
• Morning jaw discomfort
• Dental sensitivity related to wear
• New crowns, bridges, implants, or extensive restorations requiring protection
• A history of bite rehabilitation or full-mouth treatment

What Is the Difference Between a Night Guard and an Occlusal Splint?

The terms are sometimes used interchangeably, but appliances may have different designs and objectives.

• Protective night guard: Primarily designed to reduce direct wear and damage to teeth or restorations.
• Occlusal splint: Designed with controlled tooth contacts and may support diagnosis or management of selected muscle or joint symptoms.
• Temporary diagnostic appliance: May be used for a limited period to observe symptom or bite responses.

The design should match the diagnosis rather than being selected by thickness or material alone.

What Happens During the Assessment?

1. History: Reviewing grinding, clenching, pain, headaches, sleep, trauma, medication, stress, previous appliances, and medical conditions.
2. Teeth and restoration assessment: Checking wear, cracks, fractures, mobility, sensitivity, fillings, crowns, bridges, veneers, and implants.
3. Gum examination: Evaluating gum health and tooth support.
4. Bite assessment: Reviewing tooth contacts, jaw movements, missing teeth, and available appliance space.
5. Muscle and joint review: Assessing tenderness, movement, sounds, locking, or limitation.
6. Sleep and medical considerations: Identifying symptoms that may require medical or sleep-related assessment.
7. Appliance planning: Selecting the arch, coverage, material, thickness, retention, and contact design when treatment is appropriate.

How Is a Custom Night Guard Made?

1. The teeth and gums are examined.
2. A digital scan or dental impression is taken.
3. The bite may be recorded.
4. The appliance is designed for the selected teeth and treatment objective.
5. The guard is manufactured.
6. Fit, retention, borders, comfort, and bite contacts are checked.
7. Wear, cleaning, and storage instructions are provided.
8. Follow-up is arranged to review symptoms and appliance wear.

Why Choose a Custom Appliance?

A custom appliance is made from the patient’s dental records and can be adjusted for fit and bite contacts.

Over-the-counter appliances may be suitable for temporary use in selected situations, but poor fit, excessive bulk, movement, or uncontrolled contacts may reduce comfort or create new problems.

Does a Night Guard Stop Teeth Grinding?

Not necessarily. It primarily creates a protective barrier and redistributes selected contact forces.

Grinding may continue because it can be influenced by sleep physiology, stress, medication, stimulants, alcohol, breathing or sleep disorders, pain, neurological conditions, or other factors.

Can a Night Guard Help Jaw Pain?

Some patients with selected muscle or joint symptoms may improve with an appropriately designed appliance, but others may experience limited benefit or worsening symptoms.

Jaw pain should be assessed carefully. Dental appliances should not replace appropriate medical, sleep, pain, or specialist evaluation when indicated.

Can It Protect Crowns, Veneers, Bridges, and Implants?

A custom appliance may reduce direct loading and wear on selected restorations, especially when grinding or clenching is suspected.

Protection is not complete. Restorations can still chip, loosen, fracture, or require maintenance despite appliance use.

Should the Guard Be Worn Every Night?

The wearing schedule depends on the diagnosis and treatment objective. Some patients are advised to wear the appliance during sleep, while others may use it for selected periods or during daytime clenching.

Follow the individual instructions provided by the dental team.

How Should the Appliance Feel?

A properly fitted appliance should be stable and should not create severe pressure, sharp edges, or significant changes in the bite after removal.

Initial awareness, increased saliva, or mild pressure may occur. Persistent pain, tooth movement, gum injury, jaw locking, or bite changes require review.

How Is a Night Guard Cleaned?

• Rinse it after use
• Brush gently with an appropriate soft brush
• Use cleaning products compatible with the material
• Avoid hot water
• Allow it to dry as instructed
• Store it in a ventilated protective case
• Keep it away from pets and heat
• Clean the teeth before wearing it
• Bring it to dental appointments for inspection

How Long Does a Night Guard Last?

Longevity depends on:

• Grinding and clenching intensity
• Material and thickness
• Fit and bite contacts
• Cleaning and storage
• Changes in the teeth
• Dental treatment completed after fabrication
• Damage from pets, heat, or dropping

Patients with heavy grinding may wear through an appliance more quickly and need periodic replacement.

Can the Guard Be Adjusted?

Yes. Professional adjustment may be needed when:

• It feels too tight or loose
• The bite feels uneven
• It causes gum or tooth discomfort
• Dental treatment has changed tooth shape
• The appliance has worn
• Symptoms have changed

Do not trim, heat, bend, or grind the appliance at home.

What if the Guard No Longer Fits?

A change in fit may result from:

• New crowns, fillings, or bridges
• Tooth movement
• Orthodontic treatment
• Damage or distortion
• Gum or bone changes
• Wear of the appliance

Stop forcing the appliance into place and arrange an assessment. A new scan, adjustment, or replacement may be required.

Is a Night Guard the Same as a Sports Mouthguard?

No. A night guard is designed for grinding, clenching, or selected bite-related purposes. A sports mouthguard is designed to reduce dental injury during athletic activity.

The appliances are not automatically interchangeable.

Can a Night Guard Treat Sleep Apnoea?

A conventional night guard is not a treatment for obstructive sleep apnoea. Snoring, witnessed breathing pauses, choking during sleep, excessive daytime sleepiness, or morning headaches may require medical or sleep assessment.

Using the wrong appliance without appropriate evaluation may delay diagnosis of a significant sleep condition.

What Are the Alternatives?

• Monitoring mild wear
• Repairing damaged teeth or restorations
• Managing daytime clenching habits
• Reducing relevant stimulants or behavioural triggers with appropriate guidance
• Medical review of contributing medication or health conditions
• Sleep assessment when indicated
• Physiotherapy or pain-management referral in selected cases
• Bite or restorative treatment when clinically necessary

What Are the Risks and Limitations?

• Temporary pressure or increased saliva
• Difficulty sleeping with the appliance
• Gum or tooth irritation
• Changes in tooth contacts if fit is poor or wear is not monitored
• Tooth movement with an unsuitable appliance
• Continued grinding or clenching
• Limited improvement in muscle or joint symptoms
• Appliance fracture or wear
• Need for adjustment or replacement
• Delayed diagnosis of another medical, sleep, or pain condition
• Risk of swallowing a small detached component if the appliance breaks

When Is Prompt Assessment Needed?

Arrange prompt dental review if the appliance causes severe pain, gum injury, tooth mobility, jaw locking, a persistent bite change, breathing discomfort, fracture, or becomes loose enough to create a swallowing risk.

Difficulty breathing, severe facial swelling, neurological symptoms, significant jaw trauma, or major deterioration requires urgent medical care.
