If it is shaking periodically stomatitis If you have stains on the inside of your lips, it may be related to the type of toothpaste you’re using.

Yes, it seems unfair to you, a responsible oral caregiver, to be penalized for oral lesions simply for practicing good oral hygiene.

However, the TikTok account Twice Oral Wellness (Follow) accused toothpaste manufacturers such as Crest of knowingly lacquering their products with cleaning agents that lead to canker sores.

“Now, if you’ve ever had or currently have a canker sore, listen up: What’s a canker sore? It looks like this,” the TikTok user says, pointing to a part of the green-screen video that shows a close-up photo of a canker sore.

“There are many different causes of canker sores, but one of the biggest and most unnoticed causes is the ingredients in your toothpaste,” he asserts. “Turn your toothpaste over, look at the ingredients list, and see if it contains sodium lauryl sulfate (SLS).”

At this point in the video, another green screen image pops up for the viewer to see: a package of Crest toothpaste and a list of the various ingredients it contains.

“SLS is an irritant that causes mouth ulcers, so think twice before switching to the SLS-free toothpaste linked in our profile,” he says at the end of the video.

is that true?

According to Seagrass Dental Care, SLS can contribute to the development of canker sores in the mouth, and the detergent is “one of the most common causes of toothpaste-related canker sores. ” So why do toothpaste manufacturers put this substance in their products?

That’s because this detergent creates a foaming effect: “SLS is a detergent that is added to toothpaste to enhance lather and create a satisfying lather,” writes Seaglass Dental.

But this benefit comes at a steep price, according to dental groups: “However, SLS can damage delicate tissues in the mouth, causing irritation and inflammation that can lead to canker sores.”

It doesn’t just damage your mouth: “SLS is also a known skin irritant and has been linked to other health issues, including skin allergies and eczema,” according to the outlet. The same article slamming SLS for its oral health effects also mentioned another substance commonly found in toothpaste that can damage your gums. Propylene glycol.

According to a list of SLS-free toothpastes on Amazon, some popular brands include: SLS-free toothpasteSensodyne, Tom’s, Arm & Hammer Essentials, Hello, Verve, Burt’s Bees Purely White, Bio-Ten, David’s… the options consumers can choose from span a range of price points.

Crest wrote on its website: Every type of toothpaste they make is packed with SLS, but the company claims their products are safe to use: “All types of Crest toothpaste contain Sodium Lauryl Sulfate (SLS). We are aware of the rumors circulating on the internet, but SLS/SLES is safe in consumer products when used as directed. These safety concerns arise from misquoted studies and have no scientific basis. In fact, a search of the scientific literature has found nothing to support these claims. We have thoroughly tested our products to ensure they are safe.”

One person shared an anecdote about their decision to switch from SLS toothpaste to a detergent-free product: “This is so true. My life has changed since I switched to SLS-free toothpaste. I no longer get scratches.”
