my dentist told me to use ACT and i use it anywhere from 1 to 3 times a day. i also use more then 10 ml.. nothing ever happened.. and now you have me curious in weather i shouldnt be doing this.

ive been doing that for months now though, and i have no problems.

your fine doing it more then once a day but stick to the same amount cause it's won't change anything...and remember not to drink or eat after wards..and if possible rinse with it for about 2 minutes to reach the best results...thanks
