Impressive!
Impressive!  I've only had this product a few days and believe me, I received it in the nick of time.  I THOUGHT I wanted to switch from 10%/overnight to 35%/30 minutes.  I had no issues at all with 10% so I thought it would be quicker to bump on up to 35% and only need 30 minutes.  WRONG answer for me!  The second day of my new routine left my bottom teeth so sensitive, I had pain in my jaw.  It was like 10,000 bees stinging.  I immediately figured I had nothing to lose by at least trying this gel.  I put it in the tray and even though it was NOT instant relief, it seemed to calm the stinging down enough for me to get comfortable.  I fell asleep and after six hours, it was like nothing happened.  I got up the next morning and was able to eat and drink as usual with absolutely no stinging.  I will update this review after a little more time but the way it stands now, I won't be without this gel again.  I have a sensitive tooth in the very back of my mouth I am hoping to improve with overnight trays.  No noticeable improvement yet but it's only been three days.  Crossing my fingers!  **UPDATE**  After using this product for about 14 days (twice a day for 45 mins) I can tell a major difference.  I ended up bleaching at 15%/overnight which wasn't bad but I could tell it could have easily gone bad quickly.  An easy 30-45 mins with this after bleaching I was set!  I can also tell a big difference on my problem tooth.  It's not completely gone but much better. One small note (and it's kinda picky but......) The syringes can be difficult to &#34;gently&#34; push down and it's very easy to squirt out half of the tube without trying.  Of course, sometimes you can draw it back into the syringe but depending upon where it goes, you could lose it.  Like I said, it's a small thing and certainly not enough for me to never be without this for an emergency again!
