Dentist Recommended

Our dentist recommended we use it with our water pik prior to brushing, 2 capfuls with warm water. I had a case of gingivitis. It cleared right up within a week. Teeth and mouth feel cleaner with its use.

Sams sending nasty Clean Mint flavor instead now

I have had back to back orders across multiple days now where the delivery of this item was incorrect. Sams is sending nasty Clean Mint flavor instead now of Smooth Mint for all orders. Do not buy this if you want Smooth Mint.

Horrible Aftertaste

Just like other consumers, this mouthwash will leave a weird taste in your mouth for the WHOLE day effecting the taste of everything you eat! I used this mouthwash at around 7:00 am and it is 8:30 pm and the taste of the mouthwash is still in my mouth. It has negatively impacted the taste of everything I ate today. So unfortunate.

can’t taste when using this mouth wash

I used this mouth wash for the first time before going to bed. The next day I couldn’t taste anything. It’s the same each time I use this mouthwash so I finally looked it up and apparently it effects certain people. There should be a warning on the label.

reply from Supplier Response

We're sorry that this has been your experience, Ethan. Since safety is our top priority here at Crest, we can assure you that our rinses have been thoroughly evaluated to be safe when used as directed. As well, we put a lot of thought into the design of our packaging, and we'll be sure to share your feedback with our team. We'd like to mention that CPC, an ingredient in our Pro-Health rinses, may cause a temporary aftertaste or temporary change in the taste of food in a small percentage of people. Aftertaste/change in the taste of food typically goes away shortly after product use is stopped. We hope this is helpful. We'd also like to gather some additional details for our Safety Team, so please give us a call at (800) 285-9139 when you can.

Yuck

I used it for the first time before bed after brushing my teeth. It left a weird metallic taste in my mouth. The next morning, I could still taste it!I didn't use it the next morning after brushing my teeth, but I couldn't get the taste out of my mouth. It distorted the taste of everything and made it taste bitter. Even water tasted horrible. Now I'm stuck with 3 bottles that I can't use.

Rejected batch

Returned this product due to watered down taste and left a metallic taste & feeling. I bought the same product in a single bottle at Walmart, darker in color and much better taste. I suspect the 3 I purchased were from a lot that was rejected at the manufacturer’s location.

Thanks for taking the time to leave this review, Don. All Crest oral care products undergo many quality control as well as safety tests, so we'll be sure to share your report with our teams. Because you experienced an unpleasant aftertaste, we'd recommend discontinuing further use of the bottle and ask that you set it aside for at least two weeks in case our Safety Team wants to examine it. Kindly give us a call at (800) 285-9139, so we can gather a little more information and be able to help you.
