Review on 😁 iSmile Teeth Whitening Gel Syringe Refill Pack - (3) 3ml Whitening Gel Syringes, (1) Remineralization Gel Syringe - No Sensitivity, Premium Quality, Compatible with LED Light and Trays by Debbie Markovich

I have tried different bleaches. Crest Whitestrips, HiSmile and iSmile. After 3 days I definitely noticed a difference with iSmile. This gives you more coverage than Whitestrips. I would recommend. I only have a problem with injections. It's hard to say how much to use. Sometimes throws a bunch at a time. You have to develop some kind of technique to find the right amount. I want him to tell you exactly what to use. It says you should get at least 7 treatments from one tube but the max I've gotten so far has been 4. Next time I'd love to get more detailed instructions for that part, but so far I'm happy with the product, and I hope so that my teeth will become whiter over the course of the treatment.
