You have stopped buying mass market cookware. You read the labels at the grocery store, and reduce the pile under the sink of cleaners that don't belong. Something you still use twice a day, often without giving it a second thought, is your toothpaste.
ARU brushing makes the case that a category that most people don't think about deserves the same attention you already give to everything else in the bathroom.
After all, regular tubes list 15 to 20+ ingredients with names that don't reveal what they do. Others do real work. Many do marketing work – foam, color, fun. The contrast against products with a concise, visual design is very difficult to ignore.
Is ARU Toothpaste an SLS free toothpaste?
SLS, also known as sodium lauryl sulfate, is a foaming agent in many common toothpastes. The reason your brush feels like it's doing something. It is also a detergent designed for industrial cleaning, and in the concentration used for toothpaste, it is regulated as safe.
SLS has a well-documented tendency to irritate soft tissues in the mouth and contribute to canker sores. A 2019 systematic review published in Journal of Oral Pathology & Medicine found that SLS-free toothpaste reduced the number of ulcers, the length of ulcers, the number of episodes and the pain of ulcers.
“Small changes in toothpaste can really make a difference in a patient's life,” Diana Messadiprofessor and chair of oral medicine, oral diseases and orofacial pain at the UCLA School of Dentistry, told The Washington Post.
All four ARU formulas have no SLS. Instead, they use cocamidopropyl betaine, a coconut-derived surfactant that creates a gentle foam and removes plaque and debris without irritating gum tissue.
What is actually in ARU Tooth Brushing
The line comes in four formulas. Does not contain SLS. All are free of microbeads, dyes, parabens, phthalates, triclosan, artificial flavors and animal testing.
Each formula shares eight basic ingredients, including cocamidopropyl betaine. Sorbitol sweetens and prevents dryness. Cellulose gum keeps the paste smooth and stable. Silica adds texture and scrubs surface stains. A combination of neem, spearmint and peppermint oils treat the taste and fresh breath. Potassium sorbate prevents the growth of fungi and bacteria in the tube. Stevia rebaudiana leaf extract rounds out the flavor without contributing to fermentation. Water holds everything together.
From there, each formula adds one or more target functions.
4 ARU Dental Formulas, Handpicked
I white toothpaste without fluoride add sodium bicarbonate to polish surface stains, calcium carbonate as a mild abrasive and calcium peroxide to break down deeper stains through slow oxidation. For anyone exploring the best whitening options without bleach trays or strips, it's a quiet, everyday option.
I fluoride-free toothpaste for sensitive teeth it uses hydroxyapatite, the same mineral that makes up natural tooth enamel. Hydroxyapatite toothpaste works by rejuvenating the teeth and filling the micro-fissures that cause hot, cold and sweet sensitivity. It's the way to go if you've been quietly avoiding ice water for years.
I gum health formula adds stannous fluoride, which strengthens enamel while reducing bacterial growth and nerve stimulation that leads to bleeding and swollen gums. I cavity protection formula it uses sodium fluoride, an effective anti-cavity standard, which reminds enamel and increases its resistance to acid erosion.
Fluoride vs. Fluoride-Free Toothpaste
To fluoride or not to fluoride is one of the biggest debates in oral care right now.
The scientific consensus is clear. Fluoride is safe in the concentrations used in commercial toothpaste, and the American Dental Association still recommends fluoride toothpaste for daily use.
“Fluoride will help slow down the process of demineralization, which is the first stage of tooth decay,” it said. Dr. David Okanoperiodontist and assistant professor at the University of Utah School of Dentistry. Also, if you have demineralization but don't have a full cavity in the tooth, fluoride can be taken to that demineralized area to help remineralize it.”
A growing number of consumers are still choosing to skip. A major concern is dental fluorosis, a cosmetic condition that occurs when young children consume too much fluoride while their permanent teeth are forming, which is a common factor in children's toothpaste choices.
Some adults report sensitivity or irritation from fluoride toothpaste. Others simply choose a short, clean ingredient list. ARU's fluoride-free whitening and sensitivity formulas are designed for the public, while the gum health and cavity protection formulas keep fluoride for those who want it.
Which ARU toothbrush is right for you?
Four formulas, four direct decisions.
If you want whiter teeth, go with a whitening toothpaste. Do your gums bleed when you brush or floss? A unique gum health formula. If you're looking for general day-to-day protection, the cavity protection formula has it covered. Does heat and cold make you pale? A toothpaste reminiscent of hydroxyapatite is designed for that.
Both fluoride-free options double as SLS-free toothpaste for anyone prone to canker sores or sensitive oral tissues.
The line is built around a simple idea that you should pay for. You have to know what's in your toothpaste, and what's in it has to have a purpose. All four formulas are available at Walmart and Walmart.com.
