$189 an arch, kit and shipping included

For the jaw that clenches all night and pays for it in the morning. Molded to your own bite, it gives your teeth a flat surface to close against instead of their own grooves.

  • Flat closing surface, so your jaw stops hunting for a position
  • Slim enough to sleep in every night, not just bad ones
  • Built on a model of your own teeth, never picked from stock sizes

Two tray sizes, S to M and M to L, so the putty covers your arch properly. Payable by HSA or FSA card, if your plan administrator allows it.

What a relaxer does that a plain guard does not

A plain guard is a shield. It stands between your teeth and takes the wear. A relaxer goes a step further and changes what your jaw closes onto. The surface is flat and even, so the muscles have nothing to lock into and no reason to keep pulling. Most people notice the difference first thing in the morning, in the side of the face rather than in the teeth.

Who it is for

  • You wake with a tight jaw, a dull ache near the ear or a headache that fades by noon
  • Someone has told you that you clench or grind in your sleep
  • A soft guard helped a little but your jaw still works all night

How you get one

  1. Order online, and the kit is in the mail within a business day.
  2. Take the bite, follow the card and the video, seal the envelope, drop it in any mailbox.
  3. Start wearing it, the bench needs three business days, then it is on its way to you.

Reach us by phone, video or text at any stage of that, in English or in Spanish. The whole route is set out in how it works.

Everything that comes with it

  • A mold kit worth $49.99, trays and putty included
  • The relaxer itself, a case with a mirror, and foam to clean it
  • Postage covered on the way out, the way back and the way out again

A month to settle the fit

  • The first month of adjustments is free
  • A rebuild costs nothing if adjusting falls short

Questions we hear about the relaxer

Relaxer against night guard

The guard protects enamel. The relaxer aims at the muscle. If your complaint is worn teeth, take the guard. If your complaint is a sore, tired jaw, take the relaxer.

Which tray size to order

S to M covers most adults with an average or narrow arch. M to L suits a wide arch or anyone who has been told they have a large bite. When in doubt, message us with a photo before you order.

Whether it fits

Every relaxer is cut on a model of your own teeth by lab technicians. Anything that presses or rocks is ours to fix for a month, with a rebuild included if adjusting falls short.

Wearing it every night

That is what it is for. It is slim, it clears your lips and it is meant for nightly wear rather than occasional rescue.

Upper or lower

The upper stays put more easily and is the usual choice. Go lower if you gag easily or if someone has already fitted you on the lower arch.

Cleaning it

Rinse it as soon as it comes out, brush it with the foam we send, and let it dry in the case. Hot water warps it and toothpaste scratches it, so avoid both.

Paying and tracking

There is nothing to pay while ordering is closed. Once it opens, cards and health spending accounts both work, and every parcel in the chain is tracked to your phone.

One flat price: $189 an arch. The appliance, the impression kit, shipping both ways and 30 days of adjustments — all in.

HSA and FSA accepted

Two tray sizes, S to M and M to L, at the same price.

Sound familiar?

  • Waking up with a tight jaw
  • Grinding loud enough that someone else hears it
  • Front edges that look shorter every year
  • Drugstore guards that never fit and end up in a drawer

How it happens

After checkout, a licensed dentist in your state reviews your photos. Your impression kit ships only after that review.

  1. Order online and your impression kit arrives by USPS in 3 days or FedEx overnight
  2. Take the mold at your own table and mail it back with the prepaid label
  3. We build your relaxer in 3 business days and ship it to your door
  • Free shipping both ways
  • Custom made in a Florida dental lab
  • 30 days of free adjustments

Am I the right candidate?

  • You are 18 or older
  • You wake with a tight jaw or an ache that fades by noon
  • Someone has told you that you clench or grind in your sleep
  • A soft guard helped a little but the jaw still works all night
  • Your own teeth are sound and standing
  • 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
  • Worn teeth rather than a tired jaw is the complaint
