What is a night guard?

A night guard balances the pressure created by the jaw muscles throughout the night. It reduces friction and slows down enamel loss. It lowers the risk of cracks and protects restorations. It is transparent, removable, and custom-made. It can be designed for the upper or lower jaw. Its thin design does not affect speech or breathing. Hard, soft, or double-layered options are available. The goal is to protect the teeth and joint from damage. It is not to stop the habit, but to reduce its effect. The adjustment period is short and manageable. Correct measurement and proper fitting are key to success. Regular dental check-ups ensure the treatment’s effectiveness.

Quick facts (real user-focused)

• Custom-made; ready-made products are generally ill-fitting.
• Usually applied to the upper jaw; the decision is made during the examination.
• Mild pressure during the first week is normal; adjustment occurs within 7–10 days.
• The control interval is usually 3–6 months; interim adjustments are made if necessary.
• Not used as a sports mouthguard; the purpose is different.

Who should use night guards?

Those who clench their teeth at night are the first candidates. Those with morning jaw, temple, or head pain may benefit. Tooth flattening, enamel lines, and sensitivity are warning signs. It helps if there is clicking or limited opening in the TME area. Those with composites, veneers, bridges, and implants want to prevent breakage. It provides additional security during the retention period after orthodontics.

Stress, caffeine, and sleep disorders increase the risk. Office workers and those who use screens for long periods may be affected. Increased clenching during pregnancy requires a doctor’s supervision. Children are evaluated separately and plans are made according to their growth. Those who clench during the day may also try daytime use. Regular check-ups are essential for lasting comfort.

Symptom list

• Morning pain and jaw fatigue
• Tooth wear, crack lines, sensitivity
• Teeth grinding sounds and muscle stiffness during sleep

How does a night guard work?

A night guard adds a protective surface between the teeth. It reduces friction and distributes forces over a wider area. It guides the jaw joint into a more neutral position. It limits excessive muscle contraction and reduces microtrauma. It prevents new wear on the enamel. It reduces breakage and cracking in restorations. While night guards do not stop the habit, they greatly reduce the damage. The thin and smooth design provides comfort. The transparent structure does not affect social appearance. Appropriate contact points are adjusted by the dentist. Incorrect height can cause pain; adjustment provides a solution. Regular use can improve sleep quality.

Type options

• Hard acrylic: Effective at high clamping forces.
• Soft: Suitable for users prioritizing comfort.
• Double layer: Offers a balance of hard exterior and soft interior.

How to use the night guard? (Step by step)

The night guard is inserted immediately before bedtime. The mouth and guard must be clean. Mild pressure and increased saliva are normal in the first few days. The first week can start with short trials. Then, use it throughout the night. Drinking anything other than water while wearing the guard is not recommended. Remove it in the morning, rinse it with warm water, and dry it.

Store in the box, away from heat. Always use the carrying case when traveling. If you experience pain, discomfort, or loosening, make an appointment. Long-term success requires consistent use. Night guards are effective when used in conjunction with comprehensive oral care.

Steps for use

• Put it in 10–15 minutes before going to bed.
• Remove it in the morning, rinse it, dry it, and store it.
• If necessary, use gradually during the first week.

Night guard care and cleaning

A care routine extends the life of the night guard and ensures hygiene. Rinse with warm water every morning. A soft brush and neutral cleanser are preferred. Abrasive toothpaste can cause scratches. Deep cleaning is performed once a week with effervescent tablets. Avoid boiling water, sunlight, and high heat.

Alcohol-based solutions can damage the material. The tray case should also be cleaned regularly. If discoloration, odor, or cracks are noticed, an examination is required. Smoking and colored beverages increase staining. A prolonged feeling of looseness indicates a need for adjustment. Regular check-ups ensure comfort.

Care tips

• Do not use abrasive paste; choose a neutral cleaner.
• Never put it in boiling water; use lukewarm water.
• Wash the box weekly, dry it completely, and close it.

Common mistakes and misconceptions

Night guards are not a magic solution; they reduce damage. “The thicker, the better” is wrong. The height should be adjusted to the individual. Ready-made splints are inexpensive but cause fit problems. A splint that is too tight can damage the teeth. A splint that is too loose is ineffective. Leaving it in the sun and hot water causes deformation. Brushing it hard with a toothbrush scratches the surface. Overuse of cleaning tablets weakens the material. Uncontrolled use for months is not appropriate. Stress and caffeine triggers should be managed. Physician follow-up is central to the process.

Error checklist

• “The complaint is gone, I’ll stop wearing it” → Wrong.
• “A thick plate is the safest” → Not always.
• “A ready-made size is sufficient” → Insufficient for most people.
