Figure Above: New Item

Kudo Snorefighter

Figure Below: Post Custom Fit

A single piece of U-Shped thermal plastic mouthpiece has a bilateral rearward dental area and a frontal dental area with integrated outer and inner vertical walls projecting upwardly and downwardly from the base to form channels for seating maxillary (upper) and mandibular (lower) teeth, respectively. For more details, please visit: www.kudosnore.com  
    A simple custom-fit at your home is required. After custom molded fit, the upper and lower channels reposition and retain the the user's jaw (mandible) slightly forward to open air passage to reduce or inhibit snoring or sleep apnea during sleep.  
    The single piece design offers great advantage of reliability and durability. It also saves weight and is smaller to make the mouthpiece last longer, lighter and maximize comfort. For reviews, please Yahoo the key word SNOREFIGHTER or visit a review site Snorefighter Reviews  


PureSleep is an adjustable oral device for placement within the mouth of a user to reduce or eliminate snoring.

30 Day Money Back

$59.90 (Pay this amount if item is not returned within 30 days)



    The Pure Sleep comprises an upper and a lower member having upwardly and downwardly oriented channels to receive the upper and lower teeth of a user, respectively.
    Similar to Kudo Snorefighter, Puresleep uses the upper and lower channels to bias the jaw relatively forward to reduce or eliminate snoring. A custom-fit at your home is required  
    Puresleep is a two piece device, the weak point is the joints of upper and lower members. Puresleep choose to use a harder material to save the life of the joints, but still the reliability and duribility are questionable. The harder material also sacrifices the comfort fit with teeth. Feedbacks and comments on Puresleep from users are welcome. You can post or review comments from the Puresleep forum.  


Zquiet is an intra oral snoring device, similar to Kudo Snorefighter, for repositioning the users' jaw forward to open oral and pharyngeal passgeway  and preventing snoring.

30 Day Money Back

$59.95 (Pay this amount if item is not returned within 30 days)



    Zquiet has two U-shaped plate members jointed to form a so called "living hinge". The upper and lower plate members engage with maxillary (upper) and mandibular (lower) teeth respectively and connect to "living hinge" to allow some degrees of mouth openning during sleep.  

Zquiet does not require custom fit molding which is different with Kudo snorefighter and PureSleep

ZQuiet has a fixed extention of the lower jaw forward, it is not adjustable, this is different with Snorefighter and Puresleep. So if you have a severe underbite or excessive overbite teeth, it may be not working for you.

    Zquiet may cause some level of teeth discomfort and fatigue. It also could damage the gum, lips and other delicated structures of maxillary and mandible. For more details, please bellow. You may also post your comments from the link (ZQuiet Review by Users) in lower left or click here.  

Sleep Disorder Centers

Many dentists now offer anti snoring devices to sleep apnea patients and snorers. The issue is the expenses are not reimbursable for most insurances.  




    The cost of $300- $1,800 and time associated with doctor's visit and being fitted for the custom made appliances may not be affordable for most users.

Based on my 16+ years study on snoring, yes, ZQuiet does stop snoring for a good percentage of people. Because it applies the same theory as Snorefighter and Puresleep, which lift your lower jaw forward to open up breathing areas in your throat by a mouthpiece to allow you freely breathe. This theory has been proven by clinic study in the past 30 years. Some sleep specialists, in my local area, Dr. Richard Shoup and dentist, Dr. Larry Lockerman ( I will provide details about them separately), teamed up and developed a mouth appliance to help the sleep apnea patients and snorers. I just called Dr. Lockerman's office other day, this device will cost his patients $1,800 from dentist office along, does not include sleep specialist’s multiple office visits and overnight studies ( a overnight study in a hospital will cost arount $2,500. Most insurances cover this cost). As you can see from the summary table above, the Zquiet, Snorefighter and Puresleep offer significant savings.

What are the differences between a dentist made oral appliance and ZQuiet?

Dentist charges you $1,800 because other than multiple office visits, they will provide you a custom-fit dental mouthpiece, which will perfectly fit with your teeth so no discomfort, no teeth pain, no foreign objective feeling in your mouth. Moreover, the forward extension of your jaw is adjustable by spacers (I will provide some photo illustrations later). What does this mean to you?Let's imaging first night you wear this device, and next morning your honey tells you it does not work. What do you do? The doctor tells you add a spacer (about 0.050" thick) to extend your jaw forward further and try another night. Your wife may tell you that you still snore but quieter. This is a good sign which means the device likely will work for you. So what is next? Add another spacer? Absolutely. Please be aware that there is a limitation on how much your jaw can extend forward, just like how wide your mouth can open. If you recently watched ABC's "Dancing With Stars", the third place Ricki Lake's dancing partner, Derek Hough, suddenly could not close his mouth after a happy moment of excellent performance. Because he opened his mouth too wide and the joint of his jaw was out of the position and locked.. This joint called TMJ. I will talk about the TMJ later.


ZQuiet claims the device is ready to use, no custom-fit, no adjustment. Just simply open the box, close your eyes, consider it is a Christmas gift from your lovely one, put it in your mouth and go to bed, then wish a wonderful dream (if you have sleep apnea, you may not wish to have any dreams) and good night sleep. This likely will be true for your one since ZQuiet will likely stop your snoring, for the first time of many years, she (or he) may not know your exist for that night. But in the morning, very likely you will experience a teeth sore, or possible untouchable teeth pain. Why? very simple, no one's teeth is exactly same as others, one size of shoe does not fit to all. How can you imagine one size of ZQuiet mouthpiece can fit to everyone's mouth without teeth pain?

The Figure 1 below shows what is happening when your teeth fits to ZQuiet mouthpiece or similar type, such as Snoremender.Left is typical upper and lower teeth colored for clarity. For illustration purpose, the middle is the flattened ZQuiet mouthpiece. The upper teeth will fit into the upper half of the mouthpiece, the lower half is for lower teeth. As you can see from the right, unless your teeth is perfectly shaped as the mouthpiece, otherwise there will be some gaps and "touches" between your teeth and the mouthpiece.

Everybody talks about moving your lower jaw forward to stop snoring, this is easy when you are awake, but when you fall in sleep at night, all of your muscles relax including the muscles holding your lower jaw and tongue (you probably already know why you snore. just because of the relaxation of muscles, the tongue could fall back and block your breathing which causes snore or sleep apnea. I will write a separate article to talk about snore and jaw movement). The ZQuiet will serve as your muscle to hold your jaw forward, simply like a "clothe hanger" in your closet to hang your lower jaw on your upper front teeth. The weight of your jaw and tongue partially anchored to your lower teeth and hang on to your upper front teeth. Both of your upper and lower teeth are loaded by the mouthpiece. But the dentist's appliance does the same thing, why no teeth pain? The difference is the custom-fit. The custom fit oral appliance evenly distributes the load or pressure to each of your front teeth, not just on a single point. The "ready to use" or non-custom fit mouthpiece will only have few contact points with your teeth as seen on the right of Figure 1 below, the concentrated pressure on the teeth obviously will cause teeth pain. The zoom in illustration clearly shows which tooth is loaded. Yes, your wife (or husband) will no longer to hear your snoring, but you will no longer to have your breakfast. you may trade off snore with teeth pain..


Why Teeth Pain with ZQuiet or similar, such as Snoremender
Snorefighter, Puresleep, Dental Mouthpiece Custom Fit

Here is the list of snoring devices ready to use and not require a custom fit to your teeth:

ZQuiet, Snoremender

Here is the list of snoring devices require custom fit:

Snorefighter, Puresleep, Ripsnore, dental devices. Please let me know if you find anything else. You can post your question to the blog, i will anwser your question accordingly.


Each individual has a unigue mouth size and teeth shape, further more one's position of jaw relative to upper teeth is also different with others. This difference could make you be a overbite, underbite teeth. Idea teeth is a slight overbite, the upper teeth slightly covers the lower teeth all around. If you have a idea teeth, the likelihood ZQuiet will work for you. ZQuiet has a fixed extension designed for idea teeth. For people with excessive overbite, the fixed extension may cause your TMJ pain. The pain occurs at lower front of your ears. This simply because a fixed extension may be too much for your TMJ. For people with underbite, the ZQuiet may not work at all because the fixed extension will not move your jaw forward due to underbite. I will draw some sketches later so you can easily understand.

Is the ZQuiet right for you?

Three things for you to consider before to place your order.

First,.I always ask people to do a simple test. if you can pass the test, then theoredically the device shall work for you. Here is the test, extend your lower jaw forward as far as you comfortably can, hold it and try to snore. if you can't snore or very hard to snore, you pass the test. someone asked me what do you mean "very hard to snore"? This is relative to your normal jaw position. At this normal position, if you can snore much louder than the extended forward position, you pass the test.

Second, you must have full front upper and lower teeth. You must not use dentures. As I mentioned above, there will be some level of pressures on your front teeth with this device. The device may damge your dentures or teeth if they are not full and healthy.

Third, You must have "Ideal" teeth, that your upper teeth slightly covers lower teeth all around. I do not believe ZQuiet pre-qualification questionary asks this question, but it is critcal for sucess. If you do not have an "ideal" teeth, the extention by the device may not enough (for underbite) or too much (ecessive overbite, Kobe Bryan?). Someone may be disappointed, but please understand nothing is perfect. If you do not have an "ideal" teeth, you may try Snorefighter or puresleep since they require acustom-fit with your teeth. During the custom-fit processes, the Snorefighter and Puresleep allow you to adjust the extentions.

Do I Recomand ZQuiet?

Generally Yes. Here is why.

First,.if you have a healthy ideal teeth and pass the test above, i recommend you give ZQuiet a try. If ZQuiet stops your snoring and won't cause your teeth pain, why not. But if it works and you can not tolerate the teeth pain, you must stop use it and can switch to a custom-fit device as mentioned above. Please understand this teeth pain is not same as dental device. you do not want to move your teeth to a new position to tolerate to the mouthpice.

Second, It is convenient, no custom-fit is required.

Third, if it does not work, you can return for refund. I do not know how easy to return so please post your experience with ZQuiet to ZQuiet Reviews..


Contact Information if You Want to Return ZQuiet for Refund

Please call ZQuiet ASAP if you do not like the device, specially if you experience teeth pain after first night try, do not expect after a week or two you will feel better. It will make teeth pain worse and worse since most snorers are with ages. Your teeth will no longer be adjusted to fit with the device. They offer 30 day free try. If you do not call them for a RMA number, you will be automatically charged additional $59.95 and you are no longer eligible for refund. I found this phone number from their website:

800-281-0543 between the hours of 7:00am and 4:00pm PST for a return authorization (RMA) number

Snoring Is a Common Sleep Disorder

The Causes of Snoring

The Sleep Apnea and Health Risk


  1. Oral Anti Snoring Devices (oral snoring mouthpiece)  
  For snorer with mild or moderate obstructive sleep apnea, American Academy of Family Physiciansrecommends to use oral anti snoring device to stop snoring or improve the symptoms. An oral anti snoring device (oral anti snoring mouthpiece or formally so called mandibular repositioning appliance (MRA)) modifies the upper airway by lifts the lower jaw (mandible) and tongue.
Doctor Peter A. Cistulli and his research team from University of New South Wales released their long-term study report Treatment of snoring and obstructive sleep apnea with mandibular repositioning appliances on Sleep Medicine Review on 2004. It concluded that the oral anti snoring devices have been rigorously proven that they improve and often eliminate snoring in a large population of snorers with various severity of snoring.
Dr. Hoffstein V. from Department of Medicine, University of Toronto, St. Michael's Hospital conducted a research by using AHI (Apnea and Hypopnea Index. AHI is defined as how many apnea and hypopnea occur per sleep hour, and is calculated by dividing the numbers of hypopnea and apnea by number of sleep hours) to evaluate the affectivity of oral anti snore devices. By reviewing the clinical snoring study involving a total of 3,027 snoring patient, he found that the clinical effects of oral anti snoring devices are remarkably consistent.
The rate of the ability of oral anti snoring devices to reduce the AHI to below 10 (10 apneas or hypopneas per hour is not considered clinically significant) is 54%. He also compared the oral anti snoring devices with other treatments such as continuous positive airway pressure (CPAP machines) and surgery for long-term effects. His study indicated that oral anti snore devices improve initial AHI by 43%, CPAP by 74% and uvulopalatopharyngoplasty (UPPP) surgery reduced it by 31%.
Follow up data shows the majority of patient prefer using oral anti snore devices than CPAP machines and 2/3 of patients continue to use oral anti snore devices after at least two years.
Dr. Schmidt-Nowara W and his team from Department of Medicine, University of New Mexico focused on the side effects of the oral stop snoring devices.
The research data indicates that most common side effect is oral discomfort, hypersalivation (increased salivation) or xerostomia (dry mouth) but tolerable. Occasional occlusal side effects normally do not bother patients much. Consideration of the risks and benefits of oral stop snoring devices treatment with the other therapies suggests that oral stop snoring devices present a useful alternative to CPAP, especially for patients with moderate snoring and cannot tolerate CPAP therapy.
Kudo Snoring Research concluded that the use of oral anti snoring devices should be a first choice treatment for mild to moderate snoring, Obstructive Sleep Apnea and Hypopnea Syndrome (OSAH)

  2. Weight Control  
  The studies have shown that lose weight is the most fundamental treatment for snoring, even just a few pounds could significantly improve the snoring symptoms and effectively control the snoring.  
  3. Sleep On Your Side  
  Sleep On Your Side is better than on your back. When sleep on your back it is pretty easy to understand that the soft tissues attached to your tongue and soft palate could fall into your throat by gravity to narrow or block your breath airway and results a snoring  
  4. Quit Smoke  
  The study appeares in the American Journal of Respiratory and Critical Care Medicineunveils that upper airway could be irritated and inflamed by smoking to narrow the airway, also withdrawal of nicotine overnight could relax the muscle for tongue and throat to allow the soft tissues obstruct breath airway to cause snoring.  
  5. Avoid Alcohol Before Bedtime  
  Similar to sleep pills, alcohol relaxes the muscles and allows the soft tissues to obstruct breath airway and lead to a snoring.  
  6. Daily Practice on Deep Breathes  
  To exercise the muscles near the upper airway and strengthen the breath signals from brain.  
  7. Smiling  
  To exercise the muscles around tongue and maintain their strength during sleep.  
  8. Singing  
  Recent study by Fellow Alise Ojayfrom University of Exeter, UK showed that singing exercises could improve snoring symptoms by restoring muscle's strength near the throat.  
  9. Nasal Continuous Positive Airway Pressure (CPAP)  
  If above approaches fail or not significantly improving the snoring symptoms, CPAP could be a very good choice for treatment of sleep apnea. A pneumatic machine pumps a continuous positive pressure to a nasal mask, which gently blow the air into your throat to keep the airway open. The use of CPAP machine may be covered by insurance or Medicare if meet certain criteria per Medicare coverage Issues Manual from Department of Health and Human Services.  
  10. Snoring Surgery  
  If snoring is very severe and not responding to all other possible treatments, doctors may recommend to have surgery to remove the soft tissues in the throat to open the airway.  
  The above 10 effective ways on "how to stop snoring" can be used individually or as combination.  

  Snoring Is a Common Sleep Disorder  

Believe or not, snoring is a very common sleep disorder affecting especially men over 40 years old. 86% of men, and 60% of women snore occasionally, while 44% of men, 28% of women snore every single night.



Usually, the person who snores does not know his snoring during his sleep, but the bed partner or family members could be disrupted and can't sleep well.



The most recent research from Mayo Clinic showed the snoring could reduce the bed partner's sleep time for more than one hour every night.



More evidences indicated that long term lack of sleep could results of acceleration of aging, increase of stress hormones, and even induce depression.



If you find your bed partner is a habitual snorer, please do not ignore it, medical assistance is needed to get a good sleep for both snorer and bed partner.



For how to stop snoring, please see 10 effective ways to stop snoring.


  The Sleep Apnea and Health Risk  
  For both men and women, snoring is an indication of chance for sleep apnea, the louder of snoring, the more chance of sleep apnea.  
  Sleep apnea normally follows a loud snoring, then a deadly silence. This is because the airway is completely blocked by the soft tissues, no air through, although the lung is trying to inhale.  
  As respiration ceases, the level of oxygen in the blood drops, after 10 seconds to up to 2 minute’s silence, eventually the low levels of oxygen partially wakes the brain to send a message to lift the soft tissues in the throat and reopen the airway to breath.  
  If respiration ceases 5 times or more per hour, it can be considered as sleep apnea. The effects of sleep apnea are poor sleep quality, morning headache, excessive daytime sleepiness, loss of concentrations.  
  Further more, A report from American Stroke Associationindicates poor oxygenation in blood could cause hypoxia (low levels of oxygen) which in turn results high blood pressure, stroke and heart attack.  
  The worst thing is that 80% of people suffering from sleep apnea does not know their problem. Estimated 12 million Americans are suffering from the disease.  
  American Journal of Respiratory and Critical Care Medicine reported that one of 30 drivers could fall sleep while driving, most of them are either overweighed, snoring, daytime sleepiness, insomnia, high blood pressure, or suffering from sleep apnea.  
  If your bed partner is snoring night in and night out, and daytime sleepiness, for the sick of health for both of you, see doctor sooner is better.
