Position your tongue forward into the airway opening. This positioning allows for gentle retention of the tongue to help open the airway and reduce snoring and help sleep apnea. If you wake up place the tongue back into the airway space unless you have some nasal obstruction.
Use a very soft toothbrush with a liquid antibacterial soap to remove any debris. Then rinse and store the STM dry in the provided ventilated case. Do not use tooth pastes as they contain abrasives which can damage the STM surface over time causing it to be more susceptible to staining. Keep the device away from pets as they often will chew the device and make it unusable.
Stain, Odor, Freshness and Hygiene
A once a week complete cleaning of the STM is recommended. Soaking the appliance in one of the approved cleaning solutions can help with staining, freshness and kill harmful bacteria. Approved effervescent cleaning product include Smile Again (available online) and SnoreTek. Clinical studies have shown that these products improve appliance hygiene by killing bacteria commonly found on oral appliances.
The body initially interprets the mouthpiece as a food type material which
requires saliva. This is common and dissipates over time
Wear the device during the day will often speed the process of adjustment.
Sucking on sugarless candy will also speed the adjustment as you unconsciously
remove the temporary saliva increase.
Refit the device to improve the border seal. Pay particular attention to
compression along the sides.
Temporary use of antihistamines taken at night will help reduce saliva flow till the
body adjusts to the device. Many patients find using 25–50 mg of Benadryl
(diphenhydramine) helpful during the initial wearing of an appliance due to the
sedative effects of the antihistamine and the side effect of a dry mouth. There is
an added benefit of easier nasal breathing for patients with allergies. Medical
supervision is recommended for oral medication use.
If the patient has partial dentures and some front teeth in both upper and lower jaws, the STM may work.
If the patient has a full denture in either jaw the STM will not work. You should consider a tongue retaining device such as the AveoTSD. Contact our technical department email:

The FDA has cleared the SleepTight Mouthpiece for the treatment of snoring and mild to moderate obstructive sleep apnea in adults. Other uses are
considered “Off Label” and supervision by a medical or dental provider is recommended. The fitting process may be different for other applications.
CPAP: Its use in combination with CPAP or as a CPAP spare should supervised by your medical provider.
Teeth Clenching: The SleepTight may also be helpful with clenching, grinding and TMJ problems. This off label use should also be supervised by
Athletic mouth guard: A professional dental fitting is recommended
Can the STM be adjusted to be more effective and improve my snoring?
Solution: Refit “Tweak” the mouthpiece
If not initially successful, most people can see an improvement in their snoring by
simply tweaking the STM.
Refit the mouthpiece according to the initial instructions and move the jaw farther
toward the front. You only want to do this as far as necessary to prevent jaw
soreness. Note: the upward movement of the fitting handle. Never use a
microwave to heat the water.
Usually you can refit the device 4-5 times. The material begins to stiffen after that
and be less pliable.
Position your tongue forward into the front of the mouthpiece. You will note a
gentle suction effect on the tongue as it is being held forward to keep the airway
open and improve snoring and sleep apnea. This may be all that is necessary to
improve your snoring.
To test effectiveness bite down and try to make a snoring sound. Then after
fitting, try to make a snoring sound with the mouthpiece in place. Your sleep
partner or sleep specialist will let you know for sure.
Sometimes the mouthpiece can be adjusted a little at a time for more
improvement after as the jaw and bite adjust to the more forward position.
What can I do now, it used to work, but now I’m snoring again?
Refit the mouthpiece and compress the sides firmly.
Clenching and grinding can stretch and loosen the mouthpiece. The STM was
designed to be sturdy enough to resist some clenching. New factors restricting your
breathing, such as weight gain, nasal blockage or other bad sleep habits could be
making your snoring worse.
First try to refit the mouthpiece or buy another STM.
Why do my jaw muscles ache or why does my bite seem different?
This, in most cases resolves on it’s on within a week or so.
It is common during the adjustment period to experience some jaw discomfort. This
is caused because the ligaments holding the jaw in placed become stretched during
the night as the jaw is held forward to improve snoring.
Refit. If the problem persists, the jaw may be pushed too far forward. Refit and
move the jaw partially back toward the normal bite location. The mouthpiece can
be refitted up to 5 times. Always use the fitting handle and follow the original
Place the tongue into the breathing hole and refit less forward Positioning the
tongue into the breathing hole, results in a gentle suction pressure. This tongue
retention helps reduce the amount of jaw advancement required for snoring and
breathing improvement, which in turn reduces the amount of jaw advancement
(and soreness) required for snoring and apnea improvement.
If the snoring improves but the bite does not feel right, chew sugarless gum in the
morning after removing the mouthpiece. This will help reset your bite.
After overnight use, you can also rest your chin into your palm with their arm on a
desk top. Then allow the weight of your head to guide your jaw back into its usual
The Two device option: If you can get snoring improvement, you can fit a second
STM device to your regular bite, just fit the second device to your normal bite and consciously
do not advance the jaw. Remove and confirm. Then when you wake up, just put
that second device in for a few minutes and you will get back to normal more
Jaw pain on one side: When fitting, move the jaw straight forward uniformly. For
example if the jaw hurts on the right you can try advancing in a way that the right
side is not stretched as much as the left. This will help reduce the soreness.
Practice before fitting to get an idea of how much to do. Allow the jaw to become
comfortable again before the next fitting.
Some professionals say that the improved snoring or improved sleep apnea is
well worth the minor jaw soreness.
If the jaw ache persists and or your snoring does not improve, discontinue use of
the device and consult the prescribing medical or dental provider.
Water was too hot during the fitting.
If the water is overheated or not allowed to cool in a separate container, the
overheated water can cause a stippled rough texture. In most cases you can adjust
to this texture. However, the STM does lose some of its smoothness when put in hot
water – even at the right temperature. Extreme overheating may result in an
Do not use a microwave to heat the water since super heating can occur. If a
microwave is the only heat source, place a wooden stirring stick inside the
container during heating to prevent superheating the water. After the cooling period the water temperature is usually around 180 F.
Follow times exactly as stated in the directions and video:
Check the temperature of the device before fitting to assure that the device is not
Since the STM is moldable, it will fit in almost every situation including the
very large and small mouths.
Check the size of the STM before fitting. If it extends past your back teeth,
you can very carefully cut off the ends, which should allow it to accommodate
your mouth. You can smooth the edges while the device is pliable.
This usually passes in two weeks or less.
This is caused from the pressure applied to the teeth while the jaw is being held
forward. This situation is rare with the STM since it offers an improved customized fit
and the jaw position is held forward by the side teeth too.
Solutions, if the condition does not improve gradually you can perform the following:
Refit the device to a position with the jaw less forward.
If the front teeth and gums are still sore, cover just those parts with multiple
layers of aluminum foil and refit the device exactly the same way while using the
fitting handle fully inserted. Remove the foil before use.
Make sure that the edges do not flop over during the softening of the mouthpiece
in the hot water as this can place too much material on the front teeth.
This occurs when the fitting handle is not fully inserted or inserted backwards during
the fitting process and/ or the tongue is not used to push the material up against the
palate and tissue behind the lower teeth. Refit and perform compression as
A new device may be necessary if the opening is closed or very small.
This is an occasional problem. You can lubricate the handle with Vaseline and refit.
If you are still not able to comfortably use the STM after following these
tips, discontinue use and contact you dental or medical provider.
