Am I the right candidate?
- You are 18 or older
- You grind or clench at night and your own teeth are sound
- You wake up to worn edges, chipped corners or a tight jaw
- A drugstore guard has already failed you on fit or on bulk
- You want one arch, because one shell is how a guard is worn
- You will rinse it every morning and keep it in its case
Not the right buy if
- A tooth is loose, or a filling or a crown is moving
- Braces or aligners are on those teeth right now
- You want it to stop the grinding itself rather than take the wear
What $119, $159 and $189 buy
A night guard is a thin shell pressed over a model of your own teeth. It goes in before bed, takes the grinding your enamel would otherwise take, and comes out in the morning.
Three builds, one price each per arch. The impression kit worth $49.99, the postage in both directions and 60 days of adjustments are already inside that number.

Dentist reviewA licensed dentist in your state reviews your photos before your night guard goes into production.
MaterialsWe name every material, most online sellers name none. The soft guard is Erkodent Erkoflex EVA, 2 mm (FDA 510(k) K200125), the hybrid is Erkodent Erkoloc-pro dual laminate, 3 mm, and the hard guard is printed Keystone KeySplint Hard (FDA 510(k) K203000).
Why it costs more than budget night guardsBudget night guards are made from rubber-like plastic with no brand named. Ours is built from the same branded materials a dental office orders: Erkodent Erkoflex and Erkoloc-pro sheets. A dental office charges $200 to $400 plus visits for the same materials.
First year coveredBroke it, or the dog chewed it in the first year? We make you a new one free from your mold on file. Full terms in the Warranty Policy.
Fits, or your money backIf we can't make it fit after our free adjustments and remakes, we refund what you paid for the night guard, including the impression kit. You never pay for a night guard we can't make fit; the full terms are in the Refund Policy.
Four questions to ask any sellerIs a licensed dentist reviewing your case? Which brand is the material, by name? How many impression tries are included? Is a break in the first year replaced free? For this night guard our answer to all four is yes, and it is written on this page.
Pre-tax moneyPay with your HSA or FSA card. With pre-tax dollars, a $119 night guard costs most buyers 25 to 35 percent less out of pocket.
When a cheaper one is enoughIf you need a night guard for a few weeks only, a budget one is fine. If you will wear it for months, the branded material, the dentist review and the free year-one replacement are what you are paying for.

Soft, hybrid or muscle relaxer, side by side
These are not three sizes of one guard. What changes is the body of the shell and the job it is shaped to do at night.
| Build | One arch | Body | Made for | Under heavy grinding |
|---|---|---|---|---|
| Soft guard | $119 | One soft cushioned layer | Light grinding and a first guard | Thins out the fastest |
| Hybrid guard | $159 | Hard shell over a soft lining | A bite that chews through soft guards | Holds its shape the longest |
| Muscle relaxer | $189 | Flat, even biting surface | A jaw that wakes up tired and sore | Unloads the muscle, not the enamel |
All night guardsCustom night guardSoft, hybrid or muscle relaxer
Every build costs the same for the upper arch and for the lower.
What the muscle relaxer changes
It is the one build that is not about enamel. The surface is finished flat, so the jaw closes on an even plane instead of locking into its own worn grooves.
The flat surface
Nothing on it steers your jaw into one position, so the muscle stops hunting for that spot all night.
The morning after
People who buy it wake with a tight jaw rather than with chipped corners on the front teeth.
What it is not
An appliance, not a treatment. A sore jaw with a cause behind it belongs with a dentist first.
The muscle relaxer is $189 for the upper arch and $189 for the lower.
What a boil and bite costs you in fit
There are three ways to get a guard between your teeth, and they part company on fit rather than on the receipt.
Boiled at the sink
Softened in hot water and bitten into. It records the bite you had that evening, thick and uneven.
A stock size
Small, medium or large off a shelf. It rests on the tallest teeth and rocks on everything else.
Pressed on your model
We cut a model from your mold and press the shell onto it, so it touches every tooth at once.
A shell that is not built to your bite moves the load instead of taking it. The complaint that follows is bulk, and a guard too bulky to sleep in ends up in a drawer.

Questions we hear about night guards
How much a custom fit night guard costs
$119 for the soft build, $159 for the hybrid and $189 for the muscle relaxer, per arch, upper or lower for the same money. The impression kit, the postage both ways and the first 60 days of adjustments are already inside that price.
The downside of wearing a night guard
It has to be cleaned every morning, and grinding wears the shell down instead of your teeth, so it is a part that gets replaced. A soft guard gives way before a hybrid does, and it comes out to eat or to drink anything but water.
Why dentists push night guards
Because they see the wear before you feel it, worn edges, chipped corners and cracked fillings. That part is real. What the chair adds is the visits, and the guard itself is usually built by a lab like the one that builds ours.
How long a custom fit night guard lasts
It depends on how hard you grind rather than on a date. A soft shell thins out before a hybrid does, and one hot wash can end either. Replace it when it thins through, cracks or stops seating, and build faults are ours for 60 days.
How many hours you wear a night guard
It is a sleeping appliance. It goes in last thing at night, comes out in the morning and is not worn through the day. If a dentist has given you different instructions, follow those instead.
Whether a night guard for teeth grinding is worth it
It is worth $119 if the wear is already showing, flat front edges or chipped corners, because the shell takes that load in place of the enamel. It is the wrong buy if you expect it to stop the grinding itself.
The best custom fit night guard for teeth grinding
Light grinders start on the $119 soft build, anyone who has chewed through a soft guard goes to the $159 hybrid, and a jaw that wakes up tired is what the $189 muscle relaxer is shaped for.
Can you get a night guard without going to the dentist?
Yes. No chair and no office visit. A licensed dentist in your state reviews your photos after checkout. The impression kit lands by USPS in 2 to 3 business days, overnight with Rush, you take the mold at your own table and mail it back with the prepaid label. Keep your checkups all the same, because a dentist sees what is happening under the gum and we do not.
Can I get a custom mouthguard made at home?
That is how every guard we sell is made. The box holds trays, putty and the printed guide, the mold takes about twenty minutes, and a technician checks your photos before anything goes on the bench in Hollywood, Florida.
Which is better, a night guard from the dentist or online?
The shell is the same trade either way, and an office usually sends the work out to a lab like the one that builds ours. What differs is the bill and the trip. A chair charges the mold visit, the fitting and every adjustment as separate lines, while here it is $119, $159 or $189 an arch with postage both ways inside the number.
Is a custom night guard worth it?
Against a drugstore tray at $20 to $30, yes, if you grind most nights. A softened tray records the bite you had that evening and rests on the tallest teeth, so it moves the load instead of taking it. A shell pressed on a model of your own teeth touches every tooth at once, and that is what takes the grinding force so your enamel does not.
Whether insurance or an HSA card covers a night guard
We do not bill insurers directly. You get an itemized receipt to file with your plan yourself, and what comes back depends on the plan. HSA and FSA cards do work on it, and Affirm or Klarna split the price into four payments when the order qualifies.
It does not fit when it arrives
Tell us inside 60 days of delivery and leave the guard alone. Do not trim it, heat it or bend it. Photograph what is bothering you, keep the order number to hand and send it back as it left the bench. Adjustments and the remake cost nothing.
It cracked
A crack with nothing dropped behind it is a fault in the build, and that stands for 60 days from delivery once a technician has verified it. Your mold stays on file for 2 years, so a replacement usually needs no new impression from you.
What payment methods do you accept
Major credit and debit cards, HSA and FSA cards, and Affirm, Klarna, Sunbit or Zip to pay over time.
How long delivery takes and how to track it
The impression kit reaches you by USPS in 2 to 3 business days, overnight with Rush, your mold takes the same coming back, and the build follows. Every parcel in the chain carries its own tracking number and the updates come to your phone.
Will this actually fit my mouth
It is cut from your own mold by lab technicians in Hollywood, Florida, never picked off a tray of stock sizes. Anything that presses or shifts is adjusted free for 60 days from delivery.
