Choose A Night Guard For Protection, Fit, And Oversight
Learn how dentist-made, mail-order, and store-bought guards differ, what quotes should include, and when pain or sleep symptoms need evaluation.
A custom night guard for teeth grinding is primarily a protective appliance: it separates the teeth and absorbs wear that might otherwise affect enamel, fillings or crowns. A dentist-made guard offers the most clinical oversight, while a mail-order guard reproduces tooth shape without an in-person examination. Neither should be presented as a guaranteed cure for grinding, headaches or jaw pain.
Severe bruxism can contribute to tooth pain, enamel cracks, damaged teeth or restorations, jaw pain and headaches. A dentist can look for tooth wear and muscle tenderness, then decide whether a custom guard or another evaluation is appropriate (NIDCR, March 2025).

Night Guard Route Finder
Select your symptoms and priority. Symptoms that need examination take precedence over price or convenience.
A dentist can inspect teeth and restorations, select the design, and check fit and biting contacts. Ask what follow-up adjustments and remakes are included.
Dentist-made
Best match when examination, design selection and in-person adjustment matter. Usually the highest upfront price.
Mail-order custom
Made from your home impression, but it does not itself assess damaged teeth, gums, jaw symptoms or biting contacts.
Store-bought
A low-cost tolerance test, but it may be bulky or less secure and offers little scope for precise adjustment.

“Custom” Does Not Always Mean Dentist-Supervised
| Option | How It Is Fitted | Main Advantage | Main Limitation |
|---|---|---|---|
| Dentist-made guard | Impression or digital scan after a dental assessment | Design, fit and biting contacts can be checked and adjusted | Usually the highest upfront price |
| Mail-order custom guard | Home impression sent to a laboratory | Made to the submitted model, often for less than an in-office guard | No in-person examination; review, adjustments and remake terms vary |
| Store-bought guard | Stock form or softened and molded at home | Low-cost way to test whether you tolerate an appliance | May be bulky or insecure, with little scope for precise adjustment |
For a dentist-made guard, the dentist takes an impression with putty or a digital scanner and, in many cases, sends it to a laboratory. Custom guards are generally more comfortable than store-bought versions, and a dentist can check and adjust the appliance (Cleveland Clinic).
The oversight—not just the word “custom”—distinguishes the first two options. An at-home impression may reproduce tooth shape, but it does not by itself assess sensitive or fractured teeth, failing restorations, gum health, jaw symptoms or how evenly the opposing teeth contact the guard.
A Guard Protects Teeth but May Not Stop Grinding
A precisely fitted upper or lower guard can protect teeth from damage, according to NHS guidance on teeth grinding. It may not stop the underlying sleep-related jaw-muscle activity.
A Cochrane review found insufficient evidence that occlusal splints reduce sleep bruxism itself, while noting a possible benefit against tooth wear. The review searched studies only through May 2007, so it should not be treated as the final word. It supports the narrower promise that a guard protects teeth rather than a claim that it stops grinding (Cochrane).
Pain requires a separate assessment. Bruxism and temporomandibular disorders can overlap, but jaw pain does not establish that grinding is the cause. NIDCR says evidence that intraoral appliances improve TMD pain is limited. It advises against appliances designed to permanently change the bite and says to stop using an appliance and contact the prescriber if it causes pain (NIDCR).
Guard Design Should Match Its Specific Purpose
“Night guard” is not one standard design. An appliance may be hard, soft or made with both components. It may fit the upper or lower teeth and cover a full or partial arch.
Ask the dentist:
- Is it hard, soft or a combination, and why does that material suit my teeth and restorations?
- Will it cover the full arch? If not, why is partial coverage appropriate?
- Is its purpose tooth protection, or are you also treating a diagnosed muscle or joint problem?
- How will you check the contacts when I close and move my jaw?
- Which fitting and follow-up visits are included?
- What symptoms should make me stop wearing it and call the office?
Do not assume that soft is automatically more comfortable or hard is automatically better. The choice depends on the appliance’s purpose, retention, existing dental work and how the opposing teeth meet it.
Damage, Pain, or Sleep Symptoms Need Assessment First
Arrange a dental examination rather than going directly to a mail-order guard if you have tooth damage or sensitivity, pain in the jaw, face or ear, or a new concern about nighttime grinding. Those are among the reasons the NHS advises seeing a dentist.
Tell a medical or dental professional about loud snoring, witnessed breathing pauses, gasping during sleep or substantial daytime sleepiness. Bruxism is associated with sleep problems including snoring and sleep apnea, and NIDCR notes that referral to sleep medicine or a sleep study may be appropriate when another sleep condition is suspected.
A protective night guard is not the same as an appliance used to treat obstructive sleep apnea. An oral appliance for sleep apnea supports the jaw in a forward position to help keep the airway open. It is prescribed after a physician and patient choose that treatment, with a qualified dentist providing the appliance and follow-up (American Academy of Dental Sleep Medicine).
Stress, anxiety, some mental-health medicines, coffee, alcohol and smoking are also associated with bruxism. Do not stop a prescription medicine on your own; ask the prescriber whether the medicine or its timing warrants review.
Compare The Whole Quote, Not Just The Guard Price
A useful written quote should identify:
- Design: hard or soft, upper or lower, and full or partial arch.
- Process: examination, scan or impression, fabrication and delivery appointment.
- Adjustments: whether fitting, bite adjustment and later comfort visits are included.
- Remakes: what happens if the guard does not fit or stay seated.
- Repair and replacement: what is covered if it cracks, wears through or no longer fits after dental work.
- Insurance: the procedure code, estimated plan payment, deductible and your expected balance.
Current ADA reporting distinguishes a hard full-arch guard (D9944), soft full-arch guard (D9945) and hard partial-arch guard (D9946). A guard with both hard and soft components is reported according to its hard biting surface (ADA coding guide). A code describes the appliance; it does not guarantee that an insurer will pay.
There is no single useful national price for every custom guard. As one plan-specific example—not a cash-price average—a 2026 Kaiser Permanente Mid-Atlantic fee schedule lists member payments of $365 when codes D9944, D9945 or D9946 are provided by a participating general dentist and $561 by a participating specialist. The fees apply only under that plan and network (2026 plan fee schedule). Local cash prices and benefits can differ substantially.
Ask your insurer: “Is an occlusal guard for documented bruxism covered under my plan? Which code will the office submit? Is prior authorization required? Is there a replacement-frequency limit, and does my deductible apply?” A 2026 UnitedHealthcare policy, for example, lists the three guard codes but explicitly says that listing a code does not guarantee payment; the member’s plan document controls coverage (UnitedHealthcare policy).
Fit And Follow-Up Are Part Of The Purchase
A new guard should seat securely without being forced. If it causes persistent tooth soreness, gum injury or worsening jaw pain, or your bite remains changed after removal, stop wearing it and ask for a review. Do not keep using a painful appliance in the hope that it will reshape itself.
Follow its cleaning instructions and keep it away from heat that could distort it. Bring it to dental checkups so its fit, cracks and wear can be assessed. A custom guard may last several years with proper care, but heavy wear, poor retention and major dental work can lead to earlier replacement (Cleveland Clinic).
