Review on 🦷 Crest 3D Whitestrips Sensitive Teeth Whitening Kit: Gentle and Effective 14-Treatment Solution by Justin Jefferson

first use. Not bad. I usually have problems with teeth that become too sensitive when using strips. I never use them all the time. They say 30 minutes but I'm paranoid and only used it for 15 minutes. I've just finished my first treatment and haven't had any sensitivity issues or those horrible "toothpick pains" you get from bleach. So far, so good. I think it raised my tone a bit, but nothing drastic. I noticed a slight improvement. I'm an avid coffee drinker (at least 4 cups a day) and only went through half of the treatment so I'd say the average person who doesn't drink too much coffee or smoke/doesn't use the full 30 minutes will see results . I'm going to buy another box and do a full 30 minutes. Upgraded to 4 stars if there are no sensitivity issues and teeth are visibly whiter after 30 minutes of use. Edit: Tried 30 minutes the first time and had moderate sensitivity. I'll come back to the 15 minute treatments. Sensitivity lasted 3 days. It's not worth it at all. My teeth are whiter in just 15 minutes per treatment so that shouldn't be a problem.
