Review on 😃 Enhance Your Smile with Opalescence 35% PF MINT REFILL KIT: The Perfect Tooth Whitening Solution by Michelle Smith

I went from 15% daily use for 30 minutes to 35%. I could not wear a mouthguard for more than 5 minutes without severe burning and whitening of the gums, yes my gums turned paper white after 5 minutes. Needless to say I took it off, after about 5 minutes, both times I tried it the gum whitening went away and there was no more visible damage just a slight irritation which lasted about 2-3 days after that. I went back to 15% and might try 20% in the future as I've had good results at 15% and bit off more than I can chew. If that 35% accidentally stays for a long time, I might see a good hospital visit with bleeding, white, sore gums in the future. If you're worried, choose a much lower percentage and try this, I have no problem with 15% even after 30 minutes. Opalescence is still suitable for home bleaching. Be smart, lots of information from the company and others on the correct use of this product. The best thing is, if you feel something is wrong, take it off and clean your teeth and gums.
