Bruxism is a condition when a person grinds their teeth and clenches their jaw and can be especially troublesome during sleep. Grinding teeth can cause a bad night sleep, headaches, tooth damage, jaw pain or TMJ and facial pain. Needless to say, people wh


SleepGuard was invented by Lee Weinstein who has been an inventor since his early teens. He has invented products such as Laser Tag and the electronic dog collar known as Radio Fence. After graduate school at the Massachusetts Institute of Technology (MIT), he passed the U.S. Patent Bar Exam. Mr. Weinstein has done more than 2000 hours as a health care advocate including two years on the consumer council of Healthcare for All.

In 2007, he formed Holistic Technologies and designed the biofeedback headband known as SleepGuard in an effort to help people eliminate pain from TMJ and migraines.

How the SleepGuard Works

SleepGuard is designed to stop a person from grinding their teeth and clenching their jaw. The SleepGuard is a biofeedback headband that detects when a person starts to grind their teeth while sleeping by detecting muscle signals.

When the SleepGuard detects that a person is clenching their jaw or grinding their teeth while asleep, it will make a sound. The sound will wake the person reminding them to relax their jaw and stop grinding their teeth. After time, a person is supposed to hear the sound and relax their jaw without waking up.

The SleepGuard headband and sensor will also record how many times a person clenches their jaw and the total number of seconds they were clenching their jaw per night.

In order for the SleepGuard to fully work when you are asleep, there are a few things you should practice during the day while wearing the SleepGuard headband.

  • When doing a normal activity while wearing the SleepGuard headband, relax your jaw as soon as you hear the biofeedback sound on the quietest level. This practice will teach you to unclench your jaw while asleep, even when dreaming.
  • Imagine yourself doing this normally and naturally each time you hear this sound.
  • Imagine yourself waking refreshed and rested each morning.

The SleepGuard Headband Hardware

The SleepGuard headband has two sensors in it to monitor a persons clenching. The headband is fully adjustable and hypoallergenic. The headband does not put an electrical current or electromagnetic field into your body. The sensor in the SleepGuard headband allows you to select the following settings.

  • Score shows you the number of times you clenched your jaw since you last reset the headband.
  • Time is the total duration you were clenching your jaw since the last reset.
  • Volume sets the volume of the biofeedback tone.
  • Bite Level: This setting is how hard you will have to bite to trigger the biofeedback sound.

The SleepGuard headband sound touches your forehead allowing you to hear it in both ears and making it less likely it will wake your partner. This technology is the patented SleepGuard RelaxTone sound.

The SleepGuard tone will sound in three different levels.

  • Faint, which sounds for 2 seconds giving you time to unclench your jaw before waking.
  • If you do not stop clenching your jaw, the tone will get louder to a level that you set.
  • Alarm sound will go off after 5 seconds and will continue until you stop grinding your teeth or after 30 seconds when the unit shuts off.

SleepGuard Customer Comments

As with many health products, they affect people differently. The SleepGuard has fair to good customer comments. For some, the SleepGuard did not help them and for other people, they were greatly helped. Possibly, the people that were not helped, did not do the daytime exercises. Some of the comments suggest that the daytime training can help the most with the nighttime clenching. A few positive comments include.

  • "… I can say without a doubt it works tremendously. Also, in regards to the expensive price tag, they let you use it for free for 30 days if you send them your results. So you can use it for free to see if it works before you decide to buy it. After that, they offer a $50/month rent-to-own plan. I used this, and it cured the headaches, jaw aches, and dizziness that I was experiencing from grinding my teeth at night.  I am not affiliated with the company." - Amy (
  • "I appreciate that we’re all different, and different things work for different people… because you can try it for a month without paying for it, I encourage anyone suffering from bruxism to try it and see if it works for them. It saved my life! The biofeedback headband finally allows me to sleep without the fear I’ll wake up with a cracked tooth. From the first night I tried it, I stopped waking up in pain from clenching. Completely improved the quality of my life. So, it *might* not work for you, but it’s definitely worth trying. It cost less than half than my last dentist nightguard, so I really don’t think it’s that expensive. Much less than a crown!" - Mylene (

GrindGuardN was invented by Joe Pelerin DDS, who graduated from the University of Michigan in 1973. After two years of general dentistry in Massachusetts, Dr. Pelerin returned to Michigan where he has had a practice since 1975. He is one of the most recommend dentists in Auburn Hills, MI. After years of suffering problems from teeth grinding, he invented the GrindGuardN. 

GrindGuardN Teeth Grinding Solution

The GrindGuardN is patented and FDA approved to stop teeth grinding and is one of the smallest bite guards available. The GrindGuardN is unique compared with other teeth grinding guards with its central power bar. This central power bar refocuses bite forces at the front midline of their dental guard.

The advantages of the GrindGuardN are:

  • Is one-third the size of the typical teeth grinding guards.
  • Is cheaper than most night dental guards and is guaranteed to outperform other dental guards that can cost $800 and more.
  • You can reform the GrindGuardN as many times as you need to.
  • Lasts longer than typical night dental guards.
  • GrindGuardN is FDA approved to treat teeth clenching.

How GrindGuardN Works

According to Dr. Pelerin, cheaper over-the-counter types of night dental guards can actually increase teeth grinding and jaw clenching. The central bar of the GrindGuardN releases the stimulus for clenching in the first place, which reduces grinding and clenching by as much as 70%. GrindGuardN can reprogram the muscles and reduce grinding and jaw clenching.

GrindGuardN should not be used by:

  • Children under 12 years old.
  • Those wearing braces.
  • Someone who has a longer upper front tooth than the other teeth.
  • People with severely angled front teeth.
  • For more information about those who should not use this product, please see their video on YouTube.

GrindGuardN Customer Comments

Dr. Pelerin has very good customer ratings and comments for his dentistry practice as does his GrindGuardN teeth grinding dental guard.

  • "I have to use a night guard because I grind my teeth really badly. It is most important to use the night guard regularly in order to get the best benefit of the guard. Whenever I fail to use the night guard, I suffer consequences of sensitive teeth and gums, headaches, sore neck and tight shoulders. Believe me when I say that using the night guard for grinding is a wonderful resolution for the unnecessary painful results." - Karen B.
  • "Running my company and household is very stressful. Not only was I getting little sleep but the backaches and jaw pains from clenching were unbearable. Shortly after wearing GrindGuardN my aches and pains lightened up and eventually disappeared. I felt like a new person and was able to enjoy going to work and my family again. I was able to function again, no headaches, toothaches or backaches. What a life saver!" - Bob F.
