I have to admit, I was anxious to give ProSnore II a try when it came out to see what the manufacturer did to improve upon the original design. If you have not read my review on the original product yet I definitely recommend doing so.

However, I will touch on the differences between the two products later in this review, too. The manufacturer did not just tweak a few things; the entire device was redesigned, and it is even better than its predecessor.

How it Works

ProSnore II is a mandibular advancement device (MAD). It stops snoring by holding your lower jaw in a forward position. This in return keeps your airway free of obstruction. If you are newly being introduced to mouthpieces then you may be struggling to make the connection between a blocked airway and snoring.

When you fall asleep, gravity pulls your jaw back toward your throat. This allows soft tissues to become close enough to vibrate as air passes through. It is the vibration that causes the snoring. So, by holding your jaw forward it addresses this problem.

A Closer Look

testingProSnore II is an adjustable oral appliance. It is custom made to fit your mouth in a laboratory. Then, you can adjust how far you want the lower tray advanced by peeling the two pieces away, positioning your jaws, and biting down to lock it in place. This snap setting holds until you peel the pieces apart again, so you do not have to worry about them sliding during the night.

The device is made of smooth, non-irritating plastic, and it is barely noticeable when you have it in your mouth. It also features air holes, so you can breathe through your mouth.

The Fitting Process

Unlike most MADs that are molded at home using a boil-and-bite technique, this one is done in a lab. The two-piece design mimics those you would get from a dentist, which is fitting considering Dr. Gregerson helped design it. He is a seasoned dentist with more than three decades of experience.

Since everyone has a unique mouth to get the best fit the device needs to be molded to the shape of your jawline and the ridges of your teeth. The manufacturer sends you everything you need in an impression kit.

In the kit you will find an upper tray and a lower tray, and they are both clearly labeled. You will place the molding clay in the trays according to the directions and then insert them into your mouth to take an impression.

Carefully remove and send to the lab in the prepaid package. You will receive your device back in about two to three weeks. The entire process generally takes around four weeks.

Comparing ProSnore II to the Original Device

Although both devices are custom molded in a lab, they are really two entirely different products. The original one has only one lower jaw advancement setting. Whatever position it is molded into is the position you use every night. It only has a lower jaw tray, but a protruding extension that rests against the top teeth to keep the device in place.

This newer version lets you make small adjustments to the lower jaw to find your perfect positioning. Even the smallest adjustment can make a huge difference in terms of comfort and effectiveness, so this feature is a definite highlight.

The original product is white and does not have a breathing hole. Therefore, it is not suitable for individuals who breathe out of their mouth. ProSnore II is clear and barely noticeable when you are wearing it. Plus, it has airflow holes, making it suitable for mouth breathers.

The last difference is regarding price. The original sells for $119.99, and the newer one is $139.99, which is $20 more. Both do offer the option to break the price into two payments.

What Are Users Saying?

Reviews on this product are not hard to find. It is a popular device, but like all mouthpieces the reviews are mixed. Many appreciate that it is molded professionally in a lab and plenty of people say it is the most comfortable device they have tried.

Most agree that having the power to make micro adjustments to lower jaw positioning is a significant improvement from the first one. For the most part, snoring was stopped immediately. Some people had to go through a bit of a trial-and-error phase over several nights to find the perfect jaw positioning.

On the other hand, some have said that it is too bulky or they could not get used to having it in their mouth. Some have complained about how long the device takes to receive back from the lab, which is confusing considering the time frame is posted right on the website. There are also those who complain about the price because it is significantly more than other mouthpieces.

Pros and Cons

ProSnore II has some thoughtful features that distinguish it from other mouthpieces. However, like all MADs it is not without its flaws. It is important to become familiar with both positives and negatives when making your decision.


  • Snap setting design allows micro adjustments to be made in lower jaw positioning.
  • Air holes let you breathe through your mouth.
  • Molded in a lab for a custom fit.
  • Smooth and clear plastic is barely noticeable and does not irritate gums.
  • Designed by a seasoned dentist.


  • More expensive than many devices on the market, but still less expensive than the price of a prescribed one.
  • It can take several weeks to receive back from the lab.
  • There is no mention of it being BPA-free or FDA-cleared.

My Final Thoughts

conclusionThe fact that this mouthpiece is custom molded in a lab using molding clay and trays like dentists use allows you to get a good fit, which equals comfort. The ability to make micro adjustments is definitely a standout feature that distinguishes it from others. I recommend trying ProSnore II, if you don’t mind paying a higher price and waiting several weeks for the finished product to arrive.

However, in my experience, I have found other mouthpieces that cost less to be just as effective. Good Morning Snore Solution (GMSS) is one that really stands out for me. It is actually a tongue stabilizing device (TSD). So, rather than hold your jaw forward it holds your tongue instead. It is ideal for people who do not like the feeling of something in their mouth because it rests between the outer teeth and inner lips.

GMSS is ready-to-use as soon as it arrives. It is also designed by a dentist and it is cleared by regulatory agencies in the United States, Canada, and Australia. Also, the design is suitable for denture wearers. I have had a very positive experience with GMSS and recommend it if you are looking for an affordable, comfortable, and effective snoring solution.

Which device should I choose?

No one can answer this question for you. Your mouth and needs are unique, so one that I love or that your neighbor swears by may not be the best solution for you.

There are numerous products available to choose from, so if you are feeling overwhelmed this is perfectly normal. I have written several reviews on products I have personally tried and you can always use the chart I compiled for comparison purposes.
