Ahhhhhh….I am so thankful for whoever invited Canker Covers! They are the greatest invention ever! I was in so much pain from the brackets rubbing against the side of my face! It had gotten so swollen, to the point where it hurts just to breathe. Ugh, I thought I had to live with the pain for another week before it went away. So I started surfing the net to see if there’s anything I can do to relieve the pain and came across a forum for people with braces. I checked it out and lots of people were recommending this product called Canker Covers. It sounded pretty good so I decided to give it a try and stopped by Rite-Aid on the way home. So I immediately tried it on when I got home cuz I couldn’t bear the pain anymore. It came in a round, pill-like tablet. You hold it against the sore in your mouth for 20 seconds and it sticks there and 30 minutes later it forms a gel patch over the sore. I immediately felt some relief…i think the fact that something was covering the sore really helped. Even though the review said that the sore is healed the next day, I was skeptical. I didn’t think it would really work that fast. I was wrong. The next day, I felt like the sore had really healed. It wasn’t bothering me as much and the swelling has gone way down. The gel usually dissolves after 8 to 12 hours. I decided to keep using it until the sores are all healed. That product is amazing. I highly recommend it for anyone that experiences canker sores periodically. I will stock up on that for sure!
