Night Guard
A custom-made nighttime appliance designed to protect your teeth, crowns, and jaw joints from the forces of clenching and grinding (bruxism).
Protect Your Teeth and Jaw Structure Throughout the Night
Many people unconsciously clench or grind their teeth while sleeping at night. Over time, this can lead to problems such as tooth wear, crack risk, morning jaw fatigue, headaches, muscle sensitivity, and discomfort in the jaw joint. A night guard is a custom protective appliance that helps control the effects of these forces. The goal is not just to separate the teeth, but to manage the pressure generated throughout the night in a more balanced way.
The night guard helps reduce the excessive loads on the teeth and jaw system.
Every night guard is planned according to the oral structure, bite relationship, and the level of protection needed.
The goal is to protect tooth surfaces and restorations against the excessive forces generated at night.
In some patients, it can help reduce morning fatigue, muscle tension, and joint pressure.
What Is a Night Guard?
A night guard is a clear or semi-rigid intraoral appliance generally used during sleep that helps control the pressure caused by teeth clenching and grinding. It is custom-made and aims to reduce the teeth from directly damaging each other. It can also help distribute the load on the chewing muscles and jaw joint more evenly.
It helps reduce the effect of forces generated during teeth clenching and grinding on the teeth, restorations, and jaw system.
No. The type, hardness, and design of the guard are determined according to the individual's oral structure, bite, and complaints.
Not always. A night guard most often does not completely eliminate the clenching habit; however, it helps reduce the harmful effects.
Plan the Right Night Guard for You with a Detailed Evaluation
The most important aspect of night guard planning is not just determining whether the patient clenches their teeth, but properly evaluating its effect on the teeth, muscles, and jaw joint. Because while prominent tooth wear is the primary concern in some patients, morning jaw fatigue or joint complaints may be more dominant in others. For this reason, the right guard design should be determined through a personalized evaluation.
- Teeth clenching and grinding signs are evaluated.
- Wear, cracks, and pressure marks on teeth are examined.
- Bite relationship and jaw joint condition are analyzed.
- A custom night guard is planned according to protection needs.
What Happens If Bruxism Is Not Treated?
Unconsciously clenching or grinding teeth throughout the night transmits very powerful forces produced by the chewing muscles to the teeth. These forces can cause serious damage in the long term:
Tooth wear: The chewing surfaces of teeth flatten, the enamel layer thins, and the sensitive dentin underneath is exposed. In advanced wear, teeth shorten and aesthetics deteriorate. Restoration of worn teeth may require zirconia crowns or porcelain crowns.
Tooth fractures and cracks: Crack lines form in teeth subjected to continuous pressure. These cracks can deepen over time and cause the tooth to fracture. Depending on the size of the fracture, a filling, crown, or in advanced cases root canal treatment may be needed.
Temporomandibular joint problems (TMJ): Bruxism causes pain, locking, clicking sounds, and morning jaw fatigue in the jaw joint. In chronic cases, headaches, ear pain, and neck muscle tension may also accompany the condition.
Damage to existing restorations: Bruxism also poses a risk for fillings, crowns, and even implant-supported prostheses in the mouth. Under excessive forces, crowns can fracture, fillings can dislodge, and implant screws can loosen.
How Does a Night Guard Provide Protection?
A night guard (occlusal splint) is a rigid or semi-rigid appliance placed over the upper or lower teeth. It creates a barrier between the teeth during sleep, prevents tooth-to-tooth contact, and distributes clenching forces over a wider area. This way, the teeth, crowns, and jaw joint are protected.
The night guard is custom-made. An oral impression is taken, the guard is prepared in the laboratory to match the patient’s bite, and a fit check is performed. Ready-made “boil-and-bite” guards sold in stores are not suitable because they cannot achieve proper bite alignment and may worsen the problem rather than solving it.
Is a Night Guard the Same as a Retention Retainer?
No. A night guard is designed to absorb bruxism forces; its material is harder and thicker. A Vivera retention retainer is for maintaining tooth position after orthodontic treatment; it has a thinner and more flexible structure. Their purpose and material are different.
For patients who need both bruxism protection and retention, two separate appliances are planned. A fixed retainer wire protects the teeth throughout the day, while the night guard absorbs bruxism forces during sleep.
The Relationship Between Bruxism and Orthodontics
Bite irregularities can trigger or worsen bruxism. In problems such as deep bite or crossbite, certain teeth carry significantly more load than others. When the bite is corrected with Invisalign or braces, the force distribution is balanced and the impact of bruxism on the teeth is reduced. However, since bruxism is often a stress-related habit, orthodontic treatment alone may not eliminate bruxism entirely; continued use of a night guard may be necessary.
Frequently Asked Questions
We have compiled the questions we receive about this treatment and answered them as openly and transparently as possible.
It is used to help reduce the damage of nighttime teeth clenching and grinding forces on the teeth and jaw system.
Not always. However, it can provide important support in reducing the pressure and wear risk caused by teeth clenching.
There may be an adjustment period in the first few days. Usage comfort is generally higher with custom and properly planned guards.
A custom-made night guard is generally a more controlled and safer option in terms of fit to the oral structure and bite.
This depends on the intensity of use, the level of wear, and the guard's fit in the mouth. It should be evaluated through regular check-ups.
In some patients, it can help balance the pressure on the jaw muscles and joint. However, it may not be the sole solution for every joint problem.
