How often can you use it?

DFW Dental Supplies only sent me 2 syringes. Mike said he would not send my other 2 until I took down a negative review! Not fair!!!!

whats the difference between 20% and 35 %?

I think the lower strength has to stay on for a longer period of time. When I first started wiih this I kept the trays on for hours and the 35% only stays on for 1/2 hour

I have a diy mouthguard that i made from a mold. could i use that for the mouth trays or should i buy new trays?

You maybe able to use it as long as there is room for the gel in the tray.

how long do you leave it on?

I been leave it over night, and according to my dentist that was the cause of my gum damages.35% it’s too much, I should not use more than 15% or even better to be 10%
