Night dental guards protect enamel against bruxism, stabilize teeth after orthodontic treatment, correct certain snoring issues, and can even, under specific conditions, straighten minor misalignments thanks to invisible aligners. Choosing the right guard involves understanding its purpose (protection, retention, alignment, sleep), the required level of customization (standard thermoformable or custom-made in-office), wear constraints (8 to 22 hours per day), and the highly variable budget: from around twenty euros at a pharmacy to several thousand for a complete aligner treatment. Regardless, rigorous hygiene, regular professional follow-up, and the combination of a guard and a retention wire remain essential. In this regard, a retention wire made of PEEK<\/strong>, such as that offered by eZtain Lab<\/em>, provides an advantage: its biocompatible and translucent material enhances long-term stability without visible metal. <\/p>\n\n\n\n

Introduction <\/strong><\/h3>\n\n\n\n

Today, the night dental guard has become a discreet and frequently recommended solution<\/strong> in contemporary oral care. The night guard serves both medical purposes \u2014 limiting bruxism or correcting minor misalignments \u2014 and protecting enamel and improving nocturnal comfort; it is available in flexible or rigid versions depending on your needs.

Its primary objective remains protection:<\/strong> safeguarding enamel, relieving jaw muscles, and preventing micro-fissures caused by grinding. In parallel, the device is also available to ensure post-treatment follow-up<\/strong> by limiting orthodontic relapse. <\/p>\n\n\n\n

Because it is considered a healthcare act, it benefits from a strict framework: written prescription<\/strong>, potential partial reimbursement<\/strong>, and regular check-ups at a dental clinic<\/strong>.
In this article, you will discover all the use cases for orthodontic guards, possible manufacturing methods, the medical issues they address, and for each situation, the most suitable type of guard.<\/p>\n\n\n\n

Why Wear Night Guards? <\/strong><\/h2>\n\n\n\n

A night dental guard limits wear due to bruxism, keeps teeth aligned after braces, relieves certain snoring issues by slightly advancing the jaw, and, when in the form of invisible aligners worn only at night, can correct minor overlaps.<\/p>\n\n\n\n

Specifically, it plays four main roles:<\/strong><\/p>\n\n\n\n

1. <\/strong>Protecting Enamel and the Jaw Joint (TMJ)<\/strong><\/h3>\n\n\n\n

Nocturnal bruxism \u2014 involuntary grinding or clenching of teeth during sleep \u2014 can exert up to 200 kg of pressure per square centimeter<\/strong>, equivalent to a heavy bag placed on a single tooth. Under these stresses, enamel erodes, fillings crack, and the hinge between the jaw and the skull, the temporomandibular joint (TMJ), becomes irritated. A custom-made rigid occlusal splint<\/strong> acts as a shield: it fits between the arches, distributes force, and relaxes muscles, thus offering welcome relief to the jaw. <\/p>\n\n\n\n

2. Stabilizing Orthodontic Results<\/strong><\/h3>\n\n\n\n

After the removal of braces or aligners, the tissues connecting the teeth to the gums and bone<\/strong> tend to gently “pull” the teeth back to their former position.
Wearing a transparent guard every night, in addition to a white and PEEK<\/strong> biocompatible<\/strong> retention wire, ensures the necessary wear duration<\/strong> without visible metal or interference with MRIs.<\/p>\n\n\n\n

3. Improving Nocturnal Breathing<\/strong><\/h3>\n\n\n\n

Mandibular advancement splints, consisting of two coupled guards, advance the mandible by 3\u20136 mm, freeing the pharynx; efficacy<\/strong> is measured by a reduction in snoring and an increase in oxygenation scores. Gradual adjustment under clinical supervision<\/strong> optimizes comfort. <\/p>\n\n\n\n

4. Correcting Minor Overlaps<\/strong><\/h3>\n\n\n\n

Invisible aligners, such as Invisalign or Dr Smile, are actually a series of small guards that are successively worn to move teeth step by step. Worn 22 hours a day, or only at night in some versions, they gradually straighten the smile without braces or metal wires. Regular follow-up with the practitioner every two to three months allows verification that the teeth are moving as planned and prevents them from returning to their former position. <\/p>\n\n\n\n

In Summary<\/strong><\/h3>\n\n\n\n

Adopting a night dental guard<\/strong> thus addresses four concrete issues: maintaining intact enamel, keeping teeth straight, preserving respiratory comfort, and, if necessary, finalizing minor realignment. In each case, the choice of material (rigid acrylic, thermoformed<\/strong> polycarbonate), custom-made<\/strong> adjustment, and adherence to daily hygiene<\/strong> instructions determine the success of the treatment. <\/p>\n\n\n\n

What is the Price of a Night Dental Guard?<\/strong><\/h2>\n\n\n\n

Depending on the model, a night dental guard<\/strong> costs between \u20ac20 and \u20ac5,000. A rather wide range (we realize this as much as you do \ud83d\ude42 ), but one that makes perfect sense when detailed. Expect to pay \u20ac20 to \u20ac50 for a standard thermoformable guard, \u20ac150 to \u20ac300 for a rigid custom-made guard by the dentist, partially reimbursed by Social Security, \u20ac200\u2013\u20ac500 for a retention guard, and \u20ac1,600\u2013\u20ac5,000 for a complete night dental aligner program.<\/p>\n\n\n\n

1. Standard Model: The Stopgap Solution<\/strong><\/p>\n\n\n\n

The pharmacy kit, molded at home, remains the least expensive option: \u20ac20\u2013\u20ac50. Made of polycarbonate<\/g> or resin, it offers emergency enamel protection but wears out quickly. No reimbursement<\/strong> is provided, and the lack of a digital impression limits occlusal precision. Although a medical device, it is not considered for anything other than enamel protection, and its impact on the rest of the oral environment is marginal. <\/p>\n\n\n\n

2. Custom-Made Rigid Occlusal Splint<\/strong><\/h3>\n\n\n\n

For individuals who clench their teeth strongly at night, the dentist can create a rigid resin guard, custom-made from an impression or a scan of the mouth in a dental laboratory.<\/p>\n\n\n\n

Usual Price: \u20ac150\u2013\u20ac300.

Health Insurance reimburses 70% of a base of \u20ac172.80 (code LBQK030); supplementary insurance often covers the rest. The advantages? A custom-made<\/strong> fit, muscle relief, and an average durability of 18 months. <\/p>\n\n\n\n

Similar to the standard model, the rigid occlusal splint is not intended to correct tooth position: it is a functional device designed to reduce muscular and joint pain<\/strong> related to bruxism and to preserve dental structures<\/strong>. It differs from invisible aligners<\/strong>, which fall under corrective orthodontic treatment<\/strong> with aesthetic and functional aims. <\/p>\n\n\n\n

3. Post-Orthodontic Retention Guard<\/strong><\/h3>\n\n\n\n

Formed from a translucent thermoformed<\/strong> sheet, it stabilizes the alignment achieved after braces. <\/p>\n\n\n\n

Cost: \u20ac200\u2013\u20ac500, to be renewed every 3 years, not covered by health insurance after age 16.
At the end of orthodontic treatment, practitioners often provide a quote that includes the retention guard or the PEEK retention wire<\/strong>: Both systems share many common features related to comfort and aesthetics.<\/p>\n\n\n\n

The retention guard, although often seen as less invasive, still suffers from its recurring cost (with an average change every 10 to 18 months) and its high rate of non-compliance, with nearly 90% of users stopping wear after 3 years, compromising the benefits of orthodontic treatment.<\/p>\n\n\n\n

4. Mandibular Advancement Splint<\/strong><\/h3>\n\n\n\n

For snorers and those with mild sleep apnea, two interconnected rigid splints slightly advance the lower jaw to prevent it from receding during sleep, which keeps the airways clear and facilitates nocturnal breathing.

Price: \u20ac600\u2013\u20ac900. <\/p>\n\n\n\n

ENT follow-up<\/strong> is a prerequisite for reimbursement: Prior approval is mandatory, but the benefits are substantial. Notably, a measurable improvement in sleep quality<\/strong> and a reduction in apnea scores are observed. <\/p>\n\n\n\n

5. Invisible Aligners (Day or Night)<\/strong><\/h3>\n\n\n\n

A complete treatment with invisible aligners, supervised by an orthodontist or offered via a remote platform, costs between \u20ac1,600 and \u20ac5,000<\/strong> depending on the complexity of the case.<\/p>\n\n\n\n

The price includes initial impressions, the series of guards to be changed every few weeks, follow-up appointments, and sometimes the final retention guard or wire.
<\/p>\n\n\n\n

No reimbursement is provided by Social Security for adults, but most practitioners offer installment payments<\/strong> over several months.<\/p>\n\n\n\n

Clinical tip:<\/strong> always request a detailed quote<\/strong> specifying the wear duration, check-ups, and any finishing aligners. The initial cost does not necessarily cover the re-fabrication of a night dental guard<\/strong> in case of loss. As part of an aligner program, check what retention options are provided. Although guards are very effective for correction, they are much less so as retention guards. <\/p>\n\n\n\n

How to Sleep with a Night Guard?<\/strong><\/h2>\n\n\n\n

Gradually introduce the night dental guard<\/strong> one hour before bedtime, check its fit, ensure daily hygiene, and stay hydrated; within two weeks, most patients no longer feel it.<\/p>\n\n\n\n
