I used this Monday and Tuesday (morning only) putting a tiny dab on my toothbrush. I used my regular toothpaste at night. Tuesday night I could feel something strange happening with my lips. I woke up Wednesday to huge red lips. They were so swollen I was embarrassed to go to work. My gums were very sore, the outside of my lips very chapped, and two small painful ulcers under my tongue. Today is Friday. The swelling is finally gone but my lips are still a little chapped. Gums are still sore and the ulcers are still just as painful. Trying Chloraseptic to help with the pain. Horrible experience!

I was influenced to buy this by someone who said it really worked to whiten teeth. I had no issues for the first few weeks, other than the unappealing salty taste. Then I woke up one morning with swollen lips. I didn't realize it was caused by the toothpaste so I continued using for a few days while trying to figure out what was happening. By this point I had lacerations on the inside of my lips and mouth and my tongue was inflamed. I was doing research on products I was using and found the reviews of this toothpaste. I switched and my condition improved greatly within 3 days. I would caution anyone against using this. It's far too abrasive on soft tissue. I am so relieved I figured out before it did lasting damage.

This stuff causes chemical burns on your bottom lip. I used it once. Toothpaste was on my bottom lip for maybe 2 minutes. The burn started immediately. I rinsed it off. All day my lip started hurting more and more and the skin got tighter and tighter. Now at the end of the day there are tiny bubbles along my lip line and a crust line forming. I'm having to use Vaseline and antibiotic ointment just to keep the pain at bay. This stuff SHOULD NOT be available on the market. It's CAUSTIC.

It has been a week since I started using this toothpaste and it has been the worst experience ever! My entire mouth, gums, cheeks, roof, tongue and lips having been on fire! My lips are swollen and constantly peeling. I have no taste and all I have been able to eat is yogurt and drink water. I am using my granddaughter's toothpaste now and pray this heals soon. Please use with caution! I wouldn't wish this experienceon anybody!

This toothpase caused an allergic reaction in my mouth and lips. I had swelling of the gums. Redne, swelling and peeling of my lips. I discontinued using it and the symptoms slowly disappeared. Then after using the toothpaste for two days, my symptoms returned. After searching online I found several reviews where others experienced the same redness, swelling, peeling and even sores. These reviews helped me confirmed my discovery. I would like to know what ingredient in the toothpaste is the cause of the allergic reaction.

I have been using this product for 14 years and I have never had an issue! It always kept my teeth white and clean! This last tube absolutely wrecked my lips and corners of my mouth. This last tube caused severe rash, bubbling at the top of my lips, inflammation and very painful burning. I am disappointed because I've used it for so long!

I used this toothpaste for the first time and took a few days before I realized what was causing my pain in my mouth. The inside of my cheeks were raw feeling, lips extremely dry and irritated. I had welps inside my cheeks and my gum were red. I don't recommend this toothpaste at all it has caused me a lot of pain and discomfort

Absolutely terrible I would give it a zero star! The arm and hammer advanced whitening 3X messed my mouth completely up. I had to go to the emergency room. My lips swelled up and my tongue has cracks now, my mouth has been dried for two weeks so far and it doesn't feel like it's getting any better! My lips swelled up and inside my cheeks and lips completely dried out.

I’ve been having a similar experience to some of the other comments. I’ve had a terrible reaction to this toothpaste. It has made my lips horribly swollen and the inside of my mouth very sore. Unfortunately there seems to be something in this that is causing an issue. I’ve used this toothpaste in the past without issue so maybe the formula has changed?

Last weekend on May 9th I used my husband's arm and hammer toothpaste and used it again May 10 along with chap stick. I noticed the morning of May 10th, when I woke up my lips were a little red and they were swollen. I thought it was one of my chapsticks low and behold I used my husband's arm and hammer toothpaste again this morning and my lips were getting the same allergic reaction they got last weekend. I'm glad I figured it out and now I know not to use this toothpaste again.
