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 Kristina Davis

Pictured above is my product after use. I should add that I use Crest 3D White and Crest Glamorous morning and night. After my first whitening with ismile and the products mentioned above, I felt a slight burning sensation and my teeth became very sensitive. The next day I used Cali Whitening (Organic) Toothpaste and Crest Mouthwash for a deep clean. The after photo was taken after 3 bleaching treatments of 30 minutes each. After the 3rd application I no longer felt any burning and my teeth were no longer sensitive. Basically, I've decided to bleach every other day this week. I will start bleaching everyday until I get the color I want. I have to say right away that I am a smoker and a coffee addict, I continued to smoke and drink coffee. I am very happy with the results. It would probably be better if I used it every day instead of smoking or drinking coffee for an hour an hour after whitening.
