Review:
The ZONE Adult Custom Mouthguard was designed and developed by David S. Frey, a neuromuscular and cosmetic dentist from California. Dr. Frey was inspired to create the ZONE Mouthguard while witnessing his 8-year old son struggling with making a boil-n-bite mouthguard.
ZONE Mouthguards is re-launching after only selling at Dick's Sporting Goods for the last five years. Now you can buy this mouthguard on Amazon.
This mouthguard is a true "custom" fit mouthguard. You can make the mouthguard fit your mouth from anywhere. You could even do it right before a game. One of the features I like about this mouthguard is that you can buy replacement putty (PVS-Polyvinyl siloxane) for $9.99 (Adult) Buy Now and $9.99 (Youth) Buy Now. So, if you mess up the mixing procedure when fitting the mouthguard or you really love this mouthguard and just want to replace the material before each season, you can do it for only $9.99.
The fitting process was very easy to do, you simply mix the two materials (putty and catalyst) together, line the mouthguard with the mixed putty, bite down and a chemical reaction begins between the two mixed materials. After you insert the mouthguard into your mouth the material will solidify or harden around your teeth. Check out the "Mouthguard Assembly" or fitting procedure in the video below. After fitting the mouthguard it had a decent fit. I have achieved better, tighter fits with other boil-n-bite mouthguards in the past.
If the material goes up into your palate or extends too far back, you can trim it easily with a utility knife.
The material that is used (PVS) to create the custom fit is widely used in dentistry to take an impression of your teeth. Polyvinyl Siloxane (VPS) is also used in audiology to take an impression for custom hearing protection or hearing aids. Polyvinyl siloxane materials have remarkable dimensional stability and are odorless and tasteless. To my knowledge, this material has never been used in a mouthguard application.
My major question mark with this mouthguard is the durability. I may be wrong but it seems like the moldable material could detach from the clear skeleton frame over time and I don't think this material has ever been used in a mouthguard. Please leave a comment in the comment section below if you have had any issues with this mouthguard.
ZONE mouthguards claim that their mouthguards increase MORA which is means that you will have better balance, flexibility and more air intake. Scientific studies have proven there's a real relationship between increased athletic performance and MORA (Mandibular Orthopedic Repositioning Appliance, A.K.A. Zone Mouthguard).
The mouthguard also comes in Youth and Adult sizes. If your not sure of what size to get check out my blog post "How To Choose The Right Mouthguard"
In conclusion, there are a ton of positive features with this mouthguard. I especially like the technique for fitting the mouthguard and the option of basically getting a new mouthguard by purchasing a replacement putty kit (which is called the ZONE-FIT MATERIALS KIT). The final fit was pretty good but not as good as some of the other mouthguards I have reviewed in the past. The only things I didn't like about this mouthguard was the bulky feeling that I felt from the mouthguard, the low profile design, which means the mouthguard doesn't cover your roots (which I'm not a fan of) and it also doesn't come with a carrying case but you can purchase one on the accessories page.

HOW I (The Author) TEST MOUTHGUARDS & WHY I CAN BE TRUSTED
My name is Ken Mitchell. I Have been fabricating custom mouthguards for more than 15 years and have been a dental technician for over 20 years. I also, have owned my own dental laboratory for over 20 years.
Besides having work experience with mouthguards, I know first hand the importance of mouthguards in the sports world. I have played several sports throughout my life at the hight school level, including basketball, football, baseball and beach volleyball. I am also a father to two sons and a daughter who have played Soccer, Football, Basketball, Volleyball, Lacrosse and Baseball ever since they were in the first grade. From time to time I have used my children to test mouthguards to get a first-hand, real-world experience with custom mouthguards and store bought mouthguards.
I search for every mouthguard on the market. Then, I purchase (with my own funds) every mouthguard I review through places like Amazon, eBay or directly from the manufacturer, just like you would, then evaluate every mouthguard based on my expert opinion. I also comb the internet to find other reviews on durability to develop a better understanding of specific mouthguards pros and cons over an extended period of time.
Every mouthguard I review, is fitted and examined by me. The only time a mouthguard is fitted by another person besides me, would be my son, who plays college football. I use him mainly to fit and use mouthguards for weight training and football.
When I review a mouthguard it must pass certain criteria to rank in my top 10.
FIT- I believe this is the most important factor in evaluating a mouthguard, because without a tight fit, all of the other criteria can be thrown out the window. When wearing a mouthguard you shouldn't have to clench your teeth to stop the mouthguard from falling out. It should fit as tight as possible.
Comfort- Comfort goes hand in hand with the fit, if the the mouthguard is comfortable you wont get distracted by focusing on your mouthguard, instead you will be focused on the game and perform at your highest level.
Protection/Tooth Coverage- With advancement in materials, mouthguards that are thick, aren't necessarily more protective than thinner mouthguards. Brands like SISU and Game On, provide thinner mouthguards that are 40-100% stronger than EVA (ethylene vinyl acetate) that is used by most mouthguard manufacturers. A proper fitting mouthguard should cover at least your first molars to provide adequate protection. A mouthguard shouldn't extend past your second molar because it could trigger the gag reflex. Also, your mouthguard should cover your gums or the roots of your teeth.
Sport- Almost every mouthguard on the market is made for use in multiple sports but there are a few mouthguards that are designed for weight training or exercising. I will break down which sport each mouthguard is better for.
Design- I examine the color variations available and the overall design of the mouthguard, the bells and whistles if you will.
Fitting process- Most boil-n-bite mouthguards are fitted with the same process, although some fitting processes are more uncomfortable than others.
*Remember to always take into consideration that every mouthguard may not suit your specific requirements. Each person is different and everyone's mouth is unique to that person. The Mouthguard Review can only evaluate the initial fit of a mouthguard and only "real world" use can show long term durability and other design flaws.
*The Mouthguard Review has no connection to any mouthguard manufacturer and has no financial incentive to rate any brand over another. All of the reviews are written and performed by one person and are 100% unbiased.
