Got this as a free sample from Dentish . My god after using it in my month had like slim coming out of my gums sore and stinging. Did not realise at first it was the toothpaste . Until I went to the hygienist she told me it was the effect of the toothpaste . I changed straight away and my month went back to normal . Terrible experience would never recommend this product ever .

Despite providing nice value, the toothpaste leaves several white strings of residue in my mouth after brushing. It happens after every brush, and from three different tubes bought while they were on sale. Seeing as many others are experiencing the same issue, its unlikely just me or just this batch.

Used Oral B a few times. Noticed my gums started. Stinging and mouth peeling. Woke up following day to a swollen top lip. My mouth is still recovering. I have ulcers under my tongue and it hurts to brush. My gums are red raw now and bleed. Horrible product.

I used to love the old Oral B range of toothpaste and used it for quite some time. Then this Pro Health one came out and Im gutted that I cant use it, as it does make my teeth white. However, it makes my inner lip peel like mad and gives me the worst ulcers under my tongue and on the inside of my lip and cheeks. My mouth hurt like crazy. And this was only after a few uses; like within a week! Will never buy again - extremely disappointed.

Ive been using this product for around 1 month now, and had peeling gums and inside of my cheeks. My dentist told me to switch to a new one but I carried on using it until it ran out. After a couple more weeks I started getting sores on the insides of my bottom lip and around my teeth. Never using this product again, absolutely awful and made my mouth sting when brushing. Please dont use this product.

My teeth were looking a bit dull after using Colgate so I decided I wanted to upgrade to something stronger and saw Oral B whitening for half price. When I was brushing my teeth it was burning the whole time and I even had tears coming out- but I thought that’s how it should be for the “whitening” to be effective. I woke up the next day and around the sides of my tongue were swollen and burning. I couldn’t eat or drink anything without excruciating pain following. Used it once and was too afraid to brush my teeth for another 2 days to follow. Have switched back to Colgate. Definitely would not recommend, and definitely keep out of reach from children. It can do serious damage.

My husband & I developed multiple ulcers & sores in our mouths for approx 3 mths when we switched from Colgate to Oral B toothpaste. At the time we couldn’t work out why, then the ‘penny dropped’ when we realised it was the change in toothpaste. Oral B toothpaste seems to be missing an ingredient that kills bacteria which seems to be creating ulcers & painful sores. We have since switched back to Colgate & have not had a sore since. Oral B need to fix this problem as they portray themselves as the ‘dentists preferred’ dental care, but their toothpaste lets them down.

I bought the whitening accelerator by mistake, have used oral B whitening toothpaste for a couple weeks. Bought the accelerator by mistake - used it once and have now got ulcers all over my tongue. Won’t be using it again, I’ve giben one star because it won’t let me give no stars

I brought this toothpaste last week. Within a day i noticed that my mouth and gums started peeling. Switched back to Colgate and no issues. To throw caution to the wind I used the Oral B again. Within 10mins the peeling started. This seems to be dangerous

I used this product for three weeks and it had no effect whatsoever on the colour or the condition of my teeth.

step 2, the gel, burnt my mouth and turned my gums white. when the white finally disappeared my gums were left red in places and sore. no warning appears on the package. this product needs to be investigated and it does not appear to be safe based on the reviews here!!!

I'm not sure if bleach is stronger than this damn thing.
Chew my mouth skins every time after brushing teeth.
Tried to google online to see if anyone complains this product, I realise that I'm one of a huge crowd. ;-(

I found this toothpaste hurt my gums and after a few minutes white stringy stuff accumulated in my mouth which i had to peel off and spit out. I had ulcers and worse inflammation than ever. Horrifying

After buying this new tooth paste for our Thailand trip my partner and I stated to notice some peeling of the tongue and cheek skin. Me the caring partner did the right thing and asked doctor google. Turns out according to doctor google it was oral thrush. My partner fretting decided we were going to make a quick stop to the pharmacy to fix this oral dilemma. Turns out not oral thrush but burnt skin from the tooth paste we were using. Thanks to oral b 3D whitening both our mouths ended u looking like bulldogs chew toys.

The oral b pro expert strong teeth makes your gums hurt and gives you ulcers! Avoid at all cost. I've only just started using it and noticed straight away that it was this product that was making my gums sore.

This toothpaste makes my mouth & lips swell and burn. I have tried it a couple of times just to be sure it was the toothpaste. I will not be buying this toothpaste again.

This product has given me ulcers and burns on the inside of my cheeks, gums and tongue. I can't believe how many other people have had similar issues and the fact that these products are still on the market. Oral-B need to sued!

This product shouldn’t be out in the market. The toothpaste has given my mouth sores! I didn’t realize that it was the cause, until it kept happening while I was using it.

I started to get extremely worried about skin peeling from inside my mouth in great strips, leaving it sore and tender. I booked a dentist appointment and my dentist asked if I use Oral B - as apparently he sees this all the time. I have switched brands and the skin peeling cleared up. I think this toothpaste should come with a warning as this apparently happens to a lot of people. Toothpaste not fit for purpose.
