JAW PAIN AND CLENCHING. I've struggled with TMD (TMJ) for a few years now, and the disorder is absolutely miserable and unrelenting. Sometimes, I cry at night and feel miserable and hopeless about it because there was nothing that helped. I was stuck! The Dentek device now gives me something to try that works better than everything else, and I have literally spent $100s of US dollars on multiple other devices and remedies. The jaw muscle is incredibly strong. No one realizes this until you have a problem. When my jaw acts up, there's nothing I can do to relax it. My symptoms get really bad, my jaw starts clicking, my jaw won't stop clenching, and it's painful to eat and talk, the night brace helps keep my back teeth apart offering me some relief. DESCRIPTION. It's lower profile (thinner) with two small T-shaped shields that position between your back teeth. TIP: I don't put it on my back teeth because of my gag reflex. Then, there's about a 3 inch adjustable band that connects the two shield pieces. This piece has a flatter profile against your teeth. It fits into the top of the shield pieces. It clicks 4-5 spots into the shield pieces on each side so you can get the perfect fit for your sized mouth/teeth. While the shields go between your back teeth, the connecting band goes on the front of your upper teeth. EASY TO USE. The device is straight forward and simple to use. There is nothing to boil and shape. There is nothing to trim. It's ready to go when you open it. Obviously, clean it before putting in your mouth is important. All you have to do is put it in your mouth. The big parts that look like shields go between your back teeth. The thin connector goes in front of your upper teeth. If it doesn't fit perfectly, take it out and make it bigger or smaller. Then, try it again until it's customized to your unique mouth. STORAGE BOX. It comes with a storage box for daytime storage. However, when your jaw gets bad, you can pull it out for daytime wear to give your clenched jaw some relief. Rinse the device and box daily. Actually, the storage box is also pretty clever too. It has holes in the top and bottom to dry everything out. It has some internal slats on the bottom of the container to keep the device from laying flat in the box. This helps prevent bacterial growth, and as a nurse I really like that. GETTING USED TO IT. Because of my gag reflex, and I just don't like weird devices in my mouth. So, I didn't like it at first. I had to try it a few nights to get used to it. TIP: I would try it out for a few hours every evening after dinner to get used to it. Put it in after dinner when you're watching TV or reading so you're distracted and not obsessing about something new being in your mouth. If that trial goes well, try it overnight. Honestly, there's nothing else that works better to give your back teeth clenching relief from the incessant pain and pressure. If you are desperate and tried everything else like me, give this Dentek device a try. OTHER DEVICES. For $25, it's more expensive than others. The other appliances out there are good ideas, but are way too thick and trigger my gag reflex. They fill my mouth with thick plastic, when I just needed help on my back teeth. Also, some are so thick and awkward, they made my bite even worse. I don't need a device to make my bite worse, I have enough troubles. RECOMMENDATION. All mouth appliances feel weird in your mouth, but if you must use something, Dektek Mouth Guard is definitely the best! Believe me, I have tried a lot of them. All good ideas, but way too bulky. Some other devices even made my problems worse. But this device is the lowest profile out there while still being safe so you don't choke on it. It is a really smart device. I would highly recommend it for relief from devastating jaw pain and tension!
