I was highly skeptical about nightguards as the first one I had from a dentist long ago was not helpful. This much more affordable version years later has literally changed my life. I used to wake up between 2:30-3:30 am almost every night with horrible migraines. Since getting my enCore nightguard, I have been sleeping through the night and can hardly wait to put it in before bed. enCore's customer service is excellent and they respond quickly. They provide detailed instructions about their product and what to do when ordering a nightguard. The process is easy. You have three options for your nightguard: a hard surface, a soft surface, and a combination surface, depending on how much teeth-grinding you do. After purchase, enCore sends the kit, and you make the mold at home, fill out the paperwork, and send it all back to them in their prepaid envelope. enCore lets you know when they have received it and they keep you updated as to their progress and when it has been shipped back to you. If it's not right, they remake it for you (which I didn't have to have done). I've recommended enCore to my family and friends because it's an amazing company and product. Don't spend $500-$600 at your dentist's office if they tell you that you need a nightguard. enCore is the way to go!
