This brand of tooth paste is terrible. You run out of paste before finished brushing your teeth. The flavor only last the short time the paste does. Once done brushing there isn’t even enough to spit out. Please go back to old recipe.

I started using Crest gum detoxify toothpaste. It caused mouth sores, swelling gums, pain in mouth, lost 2 crowns and my teeth seem to be loose. Do not recommend. There should be a lawsuit against this product. I couldn't even eat because of the pain and canker sores.

I tried Crest Gum Detoxify (with gentle whitening), about four months ago. I would squeeze out a small amount, take some water, and use it as a swish and spit. It stopped my gums from ever bleeding, but very bad things were to come, and I never suspected this toothpaste until yesterday. I started having a burning mouth, prickly tongue and sore throat. I saw an ENT, Gastro guy, Allergist. I was sure that I had developed some sensitivity to the air around me. None of the MDs were of much help. They were baffled. I had started using this toothpaste as a gargle, in the past two weeks. Things got worse. My teeth became very hot/cold sensitive, and they NEVER were, before. The pain was excruciating.
This product jumped into my head, last night. Now that I have done the research, I know it's the culprit! Do NOT use this toothpaste. Don't let anyone you love use it. If it's in your house, throw it out, now! As someone else has posted, there should be a Class Action Lawsuit filed. I wasted lots of time and money on this. Crest needs to compensate everyone in here for their time, pain and suffering. It has been terrible, for me. I want to thank everyone who posted their experiences, here. You have headed me in the right direction. I only hope we all experience a complete recovery.

I've suffered from seizures for the last 13 years. My doctor assumed it was epilepsy and had me take a lot of seizure medicine twice a day. My argument was that it's impossible to "just start having epilepsy this late in life" and have seizures all day, every week! Especially when I was super healthy all my life. I did everything the doctor told me to do like stop drinking beer, stop eating processed meats, stay hydrated, take the right amount of meds, and I didn't take any other drugs "not even **". But I was still having seizures!
3 pills a day is what the doctor had me on, now I have problems going to the restroom, but the doctor never wanted to figure out the problem, just wanted to prescribe me more and more drugs. I told him I was not comfortable with drugs because they always have side effects, and they are not organic. So, I kept a closer look at the things I was eating, drinking, doing, and what could be causing my seizures. The last time I had seizures was Oct 15th 2022, I can’t prove it but I’m pretty sure I died! It took weeks to start thinking halfway normal again, and memory is like gold when you have seizures.
So, after a few weeks, I remembered the night before I had the seizures that I used (Crest) mouthwash for whitening teeth. It has hydrogen peroxide in it to help make teeth super white. I remembered swallowing just a tiny bit of it by accident the night before. I googled what happens when you ingest hydrogen peroxide and the answer I found should scare everyone! I emailed Crest and they said “Quit using the product” ...after 13 years of seizures, they tell me that now. Why is a deadly chemical allowed to be put in a product that is used every day? Why is it still being produced? Is this the cause of a percentage of all new epilepsy cases? Of course, I have quit using all tooth products that contain hydrogen peroxide, and I feel so much better. In fact, I’ve even slowly weaned myself off the seizure meds they had me on. And “NO” seizures!

I used this toothpaste for 3 days and stopped because I started to feel tingling/burning feelings around my gums. Now my gums are red, swollen, and painful. It feels like my mouth is slightly burning. I also got a canker sore on my tongue and have a sore throat. I've also noticed small areas of white globs on my teeth and gums like others. It seems the this toothpaste has way too harsh chemical amounts in its ingredients or something and is too abrasive. I am really hoping this all goes away with time as I've switched off the toothpaste. But I do not recommend putting this stuff in your mouth.

I like to try different toothpastes, especially any that freshen breath and are good for gum health. Saw this one and bought it two days ago. It has a pleasant minty taste and a somewhat gritty texture, but not rough at all. At 6.99 for a 4.1 oz tube, this is already pretty expensive. I've only had it two days, used it three times a day, and I'm already squeezing to get more paste out of the tube. I don't mind paying more for a good quality toothpaste. My mistake for buying a small tube, but this is just not enough product for the price.

I have been suffering with mouth sores and I have noticed the sores come up every time I use Crest Toothpaste.

Crest Gum Detoxify Caused sores, canker sores, burning, gums on fire & sloughing of gums. I don’t like writing negative reviews but feel it’s important since Crest Gum Detoxify has had same effects on others per some Amazon reviews and Google searches. I never had any issues with mouth sores but after using this toothpaste for couple months my mouth developed painful sores and lesions (canker) on sides of my tongue and all my gums as well as on-fire burning gums, & sloughing of gums, even was in back of my tongue felt like.
It took me a while to connect the mouth burning, etc to the Crest Gum Detoxify and then I stopped using it and under advice of dentist I’m using sensitive toothpaste or just baking soda and a compounded Rx mouthwash named “Magic Mouthwash.” It has helped but I still have couple lesions that won’t go away and rough gums and cheeks and burning. They seem to get better then worse again. My dentist is following up with me to make sure doesn’t develop in something else.
I contacted Crest and they said they hadn’t heard of this before me (but they did say each person is different) and then they sent me a $10 Visa card. But There are reviews on Amazon and internet that contradict that. Yes, it could be an allergic reaction that is just me and some others but it all seems a little coincidental. For decades I used Colgate regular and never any issue but with me getting a little older I thought the Gum Detoxify might be advantageous since my dentist suggested, as well. This pain has caused me to stop enjoying foods and drink that I enjoy and I feel that P&G should own up to the fact that this toothpaste has caused same adverse effects in others. Just as I get the worst sore I think is healed it breaks open again. This has been going on for months now. I am regularly seeing my dentist for follow-ups. I’m a senior and this added expense I feel was avoidable if these side effects had been told on the package.

I normally use Colgate but set the tube somewhere so I have been using Crest pro health... Wrong thing to EVER do. My teeth are in so much pain and super sensitive to the point that I can't even drink warm water. I used it yesterday and the inside of my lip peeled right after brushing my teeth. This is absolutely in pain and I keep using it. After the pain I'm in, I'm staying FAR away from Crest. I've never had pain like this before, to the point that breathing through my mouth made the pain worse.. I was fine until I started using the Crest toothpaste.

I used this toothpaste for about 4 days. Had extreme burning and dry mouth. Stopped using it and still after about 6 weeks still struggling to restore the moisture in my mouth. Could peroxide have permanently damaged my tissue? Wondering if anyone else has had this problem and how long to get better. I'm getting worried that I am going to have major dental and mouth issues. Really trying to keep mouth clean and using Biotene mouthwash and probiotics to avoid thrush. Ugh. I need some relief soon.

Hello, I purchased Crest gum Protection over a month ago and now I am noticing my gums are peeling. I’ve always been a fan of Crest toothpaste and never had this problem. I have decided I am going to go with another brand of toothpaste other than Crest. This company needs to do more research in regards to what damage this toothpaste can do, before it is put out on the market. They claim that it will protect your gums…well if my gums are peeling, then their claims are null and void. In their description it does not state it will protect your gums, so why does it have “Gum Protection” on the front of the package, and my gums are peeling? False advertising.

Introduced to product sample my recent dental visit and have been an avid Crest product user for very many years. The Gum Detoxify product sample says "Deep Clean" on the small box (24g) and my home size (116g) product says "Gentle Whitening" on the box. The first active ingredient on both products is "Stannous fluoride 0.454%". After using both products during approximate 30 day period I began to notice mouth irritation like a rash/chemical burns in the roof, gums and tongue areas. I ceased use, visited a local Urgent Care facility to obtain symptom documentation & Rx steroid prescription for 4-days and returned back to previous Crest product. Maybe if Gum Detoxify is used on a limited basis? I think more study is required.

Well I normally have no problems with CREST but their charcoal Crest toothpaste has caused my tongue to feel swollen and painful. This is the first time I have tried this particular kind of toothpaste with Crest. I have used their other kinds of toothpaste in the past. I think it is linked to the toothpaste as there is a lot of tongue burning that I feel when using this toothpaste. I have now switched over to a sensitive toothpaste. I have never had a problem with tongue swelling on both sides of the tongue this way. It's so awful that my teeth on the sides of my tongue constantly rub up against my swollen tongue which is how I figured my tongue was swollen in the first place. Then I took my fingers and pinched my tongue where my teeth are touching and felt crazy pain. I think this should be checked into, maybe there is some type of chemical burn happening with their toothpaste? This is dangerous. Please contact CREST. TY! If nobody calls them I may contact them directly.

After about 1 week of using Crest Gum Detoxify I noted that the interior of my mouth was starting to peel from the sides in thin "white" strips leaving my mouth raw and uncomfortable. I also experienced pain in my front teeth, along gum lines. I noted a metallic taste in my mouth shortly after brushing my teeth and my taste buds appeared raised and irritated. In the 2nd week I changed to a brand that is for sensitive teeth and used Dentist recommended mouthwash to alleviate the discomfort. Just to be sure that the Crest Gum Detox was actually affecting me as I first stated, I tried the Gum Detoxify on the 3rd week. After 2nd brushing, my mouth once again peeled, metallic taste returned, tongue was irritated and my teeth in front hurt. I have returned to another toothpaste and started using the treatment mouthwashes again.

I thought I had coronavirus- nope after 4 days of using Crest 3D whitening I had an awful metallic taste in my mouth. Stopped a week ago and it improved somewhat - I can’t drink any carbonated without creating a nasty taste. Still feel like I have a tongue burn a week later. It’s driving me crazy - I don’t enjoy eating anything. Thankfully I found this site and realized salsa tasted extra hot and the metallic taste with numb tongue. I really hope this eventually goes away. I’m going to call my dentist for suggestions. Really hope my taste buds aren’t permanently damaged. I am so angry there were no warnings - I always considered Crest a safe brand. After seeing these reviews they have to know it can cause issues and have ignored these complaints. Unacceptable.

I used this toothpaste just a few times and I started noticing pain in my teeth and gums. Now a week or two later the pain is so bad. I could hardly stand it, the pain is spreading. I can't eat on one side of my mouth. Today I rinsed with salt water and I hope that's going to help with the pain. I may end up having to go to the dentist and spend money to try and get this fixed. I have never experienced throbbing pain in my mouth like this.

Okay. For one: this has been going on for about 2 weeks and I have been losing my mind. I can’t sleep, I can’t eat, I can barely breath without this awful disgusting taste and smell in the back of my throat. I can hardly describe it, but I’ll do my best. It is like a smoky, metallic-y, chemically, sickly sweet acetone taste mixed with breathing in welding fumes. And kind of like breathing in fumes from a perm solution.
I have tried looking into everything. Literally everything. What I’ve been eating, I’m taking no medications, what I’ve been breathing in/smelling/coming in contact with, allergies (I have none), and I have not been able to figure it out. This smell/taste has been so disgustingly terrible that I don’t even want to eat. It makes me sick to my stomach. I have sat and cried multiple times because it has been so overwhelming to have this constant nasty chemical taste and smell in my face 24/7. After looking into everything possible, I went to brush my teeth tonight (after rushing this morning I forgot to brush my teeth and the smell/taste wasn’t so bad today and seemed to be going away) I open this tube of tooth paste and immediately smell it. The same smell that has been living in my face for almost two weeks. So I googled it and I found this page. Other people are talking about this smoky chemical metallic taste and I’m so glad I found out what this is. Oh my god I could scream.
Not only have I experienced this, I have had the sloughing off of my cheek skin and random sore spots including under my tongue and ulcers in between my top gums and cheeks (I have never had ulcers before using this tooth paste). I have been losing my mind over this and I’m so glad I now know what has been causing it. If you see this, please god never use this tooth paste. This has been, by far, the most infuriating, upsetting, disgusting inconvenience to my life that I have yet to experience and I hope it goes away fully. And if you are seeing this, you are probably here trying to find out what’s wrong with you. So here it is. You found it. I’m sorry. It’s your trash tooth paste. This needs to be pulled from shelves.

I bought Crest Pro Health two weeks ago when my Colgate ran out and I was just switching things up. Immediately after I started using it my tongue would burn and my tastebuds would feel numb. I thought maybe it would go away if I kept using it. After about a week and a half I started noticing canker sores and the insides of my cheeks and lips were red and irritated. I thought maybe I was brushing too hard so I switched to a soft-bristled brush. Two days later and my tongue and cheek/lip tissue is so swollen and sore it hurts for them to even touch my teeth or food. Even doing nothing, my mouth hurts. I finally figured it out when I went to gently try and brush my teeth and the toothpaste touched my skin and burned like hell itself. After some research and finding this thread I am confident it is the toothpaste that has been destroying my mouth. It is headed into the trash and I will be buying my Colgate again ASAP.
