Crest Professional Whitestrips Whitening Treatments Reviews Summary

Whitening Effectiveness

Pros:

• "They did seem to whiten my teeth I have two more days to go."
• "Review of the CREST 20 levels whiter strips: So I followed the directions - used up 18 of the 22 strips over about 30 days without issues."
• "It works but the sensitivity is a bit extreme."
• "I was looking for something to help whiten my teeth and this was a widely known brand so I gave it a try."
• "The first 10 or so strips did whiten part of my teeth."

Cons:

• "Used it as instructed for the 22 days and really saw no difference."
• "Disappointing. I have used this product for years and notice with my last order there is barely any whitening on the strips."
• "Doing the tissue test my teeth looked yellow. After using the strips for 21 days I don't really see a difference."
• "After using all the strips, my teeths are not as white as it was advertised."
• "These work, but they made my teeth hurt."

Sensitivity and Pain

Pros:

• "Its one of the best options cost/benefit. But in my opinion the whitening can reduce over time, it lasted me 1 month good."
• "I use this strips at least 3 times a year and it works perfectly, even better after the second time."

Cons:

• "These hurt my teeth SOOO much. I followed the directions and wore them for like 40 minutes or so.. and later that day, I had never experienced such horrible sensitivity!"
• "With only 3 strips to go, started experiencing major pain on the top of my front left lower tooth."
• "I left my white strips on for about three hours and when I took them off my teeth hurt so bad, they were very sensitive for a full 24 hours."
• "If you have difficulty with having this in your mouth for long periods of time like mouth guards, you'll have difficulty with this."
• "I have never had a teeth whitening product hurt my gums the way these do."

Product Quality and Consistency

Pros:

• "I usually like this product but I’m wondering why the Bonus strips are missing."

Cons:

• "Not sure if it’s a bad batch but the latest whitening strips I’ve tried using the strip stays attached to the plastic without separating."
• "I am finding differences among the strips that I have received. Some have notches to accommodate the arc of the teeth, and some do not."
• "At first, I thought I was buying just a whitening solution like I've done before. It's only on my third application that I noticed something was different."
• "I had ordered Crest whitening strips in the past and they were grip strips so easy to put on and keep on your teeth."
• "This time, the only thing in there, were the strip packages. In earlier boxes, that I have received, there were two compartments."

Adhesion and Application

Pros:

• "I had great success with the first one but this one is terrible. The plastic that the strips are scored too deeply and separate from the page and make it nearly impossible to separate the strip."

Cons:

• "The problem is with the product itself. It says it grips teeth but the bottom didn’t grip at all."
• "For me, the strips only cover about 8 teeth or so. Does not cover the side teeth very well, or any of the back ones."
• "Had to cut these to fit them in. They only cover the front half of your teeth so your molars will still be yellow and they taste awful."
• "Kind of cumbersome to apply correctly and since it’s no longer a gel on the strip, which was good for getting into the crevices between teeth, it only whitens the front of the teeth."
• "I gave it a 3 star because although it whitens fairly well, they do not stick too well."
