How does the SleepTight Mouthpiece work?

  • The SleepTight Mouthpiece holds your jaw forward during sleep to open the airway and improve snoring. The most common cause of snoring is air being passed through a partially constricted airway causing vibration of the palate during breathing.
  • The SleepTight Mouthpiece front opening also allows for gentle tongue retention while the jaw is help forward. This also improves removes airway obstruction to improve snoring.

Can the SleepTight Mouthpiece be used with dentures, caps, crowns, veneers or fixed bridges?

  • No. SleepTight Mouthpiece product is recommended for people with a complete full denture in one or both dental arches. The STZ requires at least 4 teeth in both the upper and lower dental arches to hold the mouthpiece in and the lower jaw forward. The device is most effective if there are front teeth present. A tongue retaining device in some cases will help denture wearers.
  • The SleepTight Mouthpiece is safe to use on well cemented permanent restorations such as caps, crowns, veneers and fixed (not removable) bridges.
  • Loose teeth and recently placed dental implants should not be used as supporting teeth for the SleepTight Mouthpiece.
  • Please consult with your dentist, if you have questions about the suitability of the SleepTight Mouthpiece for your particular situation.

What is the texture like with the SleepTight Mouthpiece?

The SleepTight Mouthpiece texture remains smooth after multiple fitting increasing user comfort as compared the original SleepTight Mouthpiece. With the original version, not following the directions and overheating the water during fitting resulted in a rough texture.

Will I be able to breathe through my mouth or swallow with the SleepTight Mouthpiece?

  • Yes. The SleepTight Mouthpiece has been engineered with large breathing holes to allow you to breathe easily. This is particularly helpful for mouth breathers. This is also helpful for those with nasal obstruction caused from allergies, structural abnormalities, sinus infections, excess alcohol consumption or other blockage causes.
  • You can swallow normally with the SleepTight Mouthpiece. Unlike other mouthpieces, the SleepTight Mouthpiece does not squeeze your tongue in a bulb or hold it down with rubber bands.

What should I do if my snoring does not improve?

If you have performed the self-help steps above and you have not seen improvement, you may want to contact your medical provider for additional help.

Is there a simple test to try before purchasing the SleepTight Mouthpiece?

  • Yes. You can try this. Close your mouth with your teeth together. Then try to make a snoring sound.
  • Then open your mouth a little and move your jaw forward a little at a time and try to make the snoring sound. You will see that the snoring improves. This opening and jaw forward movement is how the mouthpiece alleviates your snoring.
  • The SleepTight Mouthpiece mouthpiece holds the jaw in that location while you sleep.

Back to top


How do I use the SleepTight Mouthpiece?

  • Simply place the SleepTight Mouthpiece in your mouth
  • Close into the pre-fitted teeth imprints
  • 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.

When will the snoring improve?

  • For most people you will know the first night, if your snoring improves. If your snoring is better even for a short while, then you know that the mouthpiece is helping.
  • Refitting the jaw more forward after a few days may also help improve your snoring. If you do not see improvement, you may want to contact your medical-dental provider for other treatment options.

How long does it take to get used to it?

  • Within a few nights. The adjustment phase obviously varies from person to person. Usually within a week or two most of the side effects have diminished or disappeared.
  • We recommend using the SleepTight Mouthpiece for at least 5 nights before making any adjustments.

Back to top


How long will the SleepTight Mouthpiece last?

  • There are many factors that can affect the life expectancy of your SleepTight Mouthpiece, and this will vary from person to person. Grinding or clenching your teeth while you sleep, how clean you keep it, and how you store it will all play a part.
  • More than half of our customers who reorder do so after 6-12 months of use, while others have used their SleepTight Mouthpiece up to 3 years before replacement.

How is the SleepTight Mouthpiece cleaned or stored?

  • Everyday rinse with cool running water and a small amount of liquid anti-bacterial soap. Never use hot water. If debris remains, you can use a very soft toothbrush or cotton swab.
  • Avoid toothpastes containing abrasives which can damage the soft SleepTight Mouthpiece surface over time causing it to be more susceptible to staining. Never use bleach, alcohol or other strong chemicals.
  • Weekly soaking the appliance with the approved oral appliance cleaner can help with staining, freshness and kill harmful bacteria. Contact info@sleeptightmouthpiece.com for our current recommendation.
  • Store the device in a cool dry location in its container.
  • Always brush your teeth in the evening before inserting the SleepTight Mouthpiece.

Will the mouthpiece cause gagging?

Rarely. Customers rarely mention gagging. If you experience this problem, wear the SleepTight Mouthpiece for a few minutes at a time during the day until the body adjusts to having something in your mouth.

Back to top


Why do I have extra saliva?

  • Saliva accumulation will decrease. The body initially interprets the mouthpiece as a food type material which requires saliva. This is common and dissipates over time.
  • Solutions: 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.

Can the SleepTight Mouthpiece be used any other way?

Currently, the SleepTight Mouthpiece is indicated for the treatment of snoring only.

Can the SleepTight Mouthpiece be adjusted to be more effective and improve my snoring?

  • Yes. Refit “Tweak” the mouthpiece If not initially successful, most people can see an improvement in their snoring by simply tweaking the SleepTight Mouthpiece.
  • The SleepTight Mouthpiece initial fit, positions the lower jaw slightly forward which in many cases will be enough to improve your snoring. This initial location also helps reduce side effects of tooth and jaw discomfort.
  • If after at least 5 nights of use, you want more improvement, you can refit the SleepTight Mouthpiece according to the initial fitting instructions. Work in front of a mirror again. Secure the fitting handle by clicking the parts back together inside the mouthpiece opening. Bite into the pre-fit tooth imprints that you made before and then while the material is soft move the jaw forward slightly. You will see the fitting handle move upward slightly. Compress as before. This can be repeated a few times if necessary and you are likely to be able to get another 2-3mm of advancement depending on your anatomy.
  • Often just keeping the tongue forward will improve your snoring and breathing. 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. Unlike other snoring devices, the SleepTight Mouthpiece does not suction the tongue with a bulb nor strap it down with rubber bands. With the SleepTight Mouthpiece you have free tongue movement and can swallow normally, which is important while sleeping.

What can I do about my dry mouth?

  • Use a mouth lubricant such as Biotene Spray
  • The good news is that the SleepTight Mouthpiece is working to open the airway. But, because you are not breathing thru your nose, the mouth dries out. You could have a nasal obstruction which forces you to breathe thru your mouth which may require and additional dental or medical evaluation.

Back to top


How can I keep my mouthpiece in because it falls out?

  • This is usually caused from a poor initial fitting process.
  • Nighttime clenching and grinding can stretch and loosen the mouthpiece too. The SleepTight Mouthpiece was engineered to with a dual laminate design to help resist this stretching.
  • You can improve the retention by using one or more of the following steps.
  • Refit the mouthpiece and concentrate on compression of the softened material toward the gums and teeth with firm finger and tongue pressure.
  • Sleep on your side. The jaw naturally drops back when you sleep on your back which causes lower jaw to drop back and lose its retention in the device. Back sleepers always have this issue no matter what device is used.
  • This tip works like magic. With the device in place, place your tongue forward into the opening, gently bite down and suck and swallow all your saliva. There will be a noticeable suction effect which will hold the jaws in their proper position. It might need to be repeated during the night.
  • You could be interfering with the device during sleep with your tongue; wear the device during the day to get used to the feeling and speed up the adjustment period.
  • If the snoring does improve but does not stay in well enough, then consider investing in a laboratory fabricated customized mouthpiece.

What can I do now, it used to work, but now I’m snoring again?

  • Refit the mouthpiece and slightly advance the mouthpiece
  • New factors restricting your breathing, such as weight gain, nasal blockage or other bad sleep habits could be making your snoring worse.
  • If refitting the device does not work discontinue use and consult a medical or dental professional.

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 become stretched during the night as the jaw is held forward to improve snoring.
  • Solutions:
    • 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 several times. Always use the fitting handle and follow the original fitting directions.
    • After moving to a less forward location try to sleep with the tongue positioned into the airway opening, which 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 desktop. Then allow the weight of your head to guide your jaw back into its usual position.
    • The Two device option: If you can get snoring improvement, you can consult with your dentist regarding a jaw re-positioner which is a mouthpiece used to reset the jaw to its original location after sleeping with the STZ.
    • 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. 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.

Why are my teeth sore or loose?

  • 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 theSleepTight Mouthpiece since it offers an improved customized fit and the jaw position is held forward by the side teeth too, not just the front teeth. You are more likely to have teeth soreness, if you have only front teeth.
  • If the condition does not improve gradually you can perform the following: Refit the device to a position with the jaw less forward; move your lower jaw backward.

Back to top


Why is there a hole where my front teeth fit?

No problem. This is not generally a concern and will not affect the performance of the device. This is caused when the user bites extremely hard during the fitting process which causes the front teeth to contact the fitting handle.

Back to top


Why is the airway small or mostly obstructed?

This occurs when the fitting handle is not fully inserted or clicked into place or the tongue is not used to push the material up against the palate and tissue behind the lower teeth. Refit and perform compression with the tongue in the front inside portion of the device. A new device may be necessary if the opening is closed or very small.

How can I remove the fitting handle?

To remove the fitting handle, squeeze the front sides and slide off the front retainer clip; then slide out the main part from the inside. Keep the fitting handle and use the same steps if additional fitting is desired.
