Analysis updated August 2026 · How Scout scores
At a glance
Summary
This toothpaste contains beneficial ingredients like xylitol, which helps reduce cavity-causing bacteria, and baking soda, a gentle abrasive that aids in plaque removal. However, the presence of sodium lauryl sulfate, a known mucosal irritant, and sodium monofluorophosphate, a fluoride source with potential toxicity concerns, lowers its overall safety profile. The product is processed, which further impacts its rating.
Key ingredients 9
XylitolVery Good
Xylitol is a natural sweetener that has been shown to reduce cavity-causing bacteria in the mouth. It helps maintain oral health by inhibiting the growth of harmful bacteria. Its cavity-preventing properties make it a highly beneficial ingredient in toothpaste.
Risks
In large amounts, xylitol can cause digestive upset.
Benefits
Xylitol reduces the risk of cavities by inhibiting harmful bacteria.
GlycerinGood
Beneficial ingredient — whole-food or functional value in this product class.
Risks
There are no significant risks associated with glycerin in toothpaste.
Benefits
Glycerin helps maintain the moisture and texture of the toothpaste.
Peppermint oilGood
Peppermint oil is a natural antimicrobial agent that helps freshen breath and reduce oral bacteria. It provides a pleasant flavor and contributes to overall oral hygiene. Its antimicrobial properties make it a beneficial addition to toothpaste.
Risks
In rare cases, peppermint oil can cause allergic reactions.
Benefits
Peppermint oil freshens breath and has antimicrobial properties.
Calcium CarbonateNeutral
Calcium carbonate is a common abrasive used in toothpaste to help remove plaque and surface stains. It is generally considered safe and effective for this purpose. However, it does not provide any additional oral health benefits beyond its abrasive action.
Risks
There are minimal risks associated with calcium carbonate when used in toothpaste.
Benefits
It helps in cleaning teeth by acting as a mild abrasive.
WaterNeutral
Water is used as a solvent in toothpaste formulations to dissolve other ingredients and provide the desired consistency. It is an inert ingredient with no direct impact on oral health. Its primary role is to facilitate the mixing and application of the toothpaste.
Risks
There are no known risks associated with water in toothpaste.
Benefits
Water helps in maintaining the consistency and usability of the toothpaste.
Sodium BicarbonateNeutral
Standard formulation ingredient — neither beneficial nor harmful at typical use.
Risks
Excessive use of baking soda can lead to enamel wear over time.
Benefits
It helps in cleaning teeth and neutralizing acids, promoting oral health.
CarrageenanBad
Processed additive flagged under Scout's ingredient doctrine.
Risks
There are concerns about carrageenan causing inflammation in some individuals, but these are primarily associated with its degraded form.
Benefits
Carrageenan helps maintain the texture and stability of the toothpaste.
Sodium MonofluorophosphateBad
Sodium monofluorophosphate is a source of fluoride, which helps in the prevention of dental cavities by strengthening tooth enamel. However, excessive fluoride can lead to dental fluorosis, a condition that affects the appearance of teeth. Its potential for toxicity in high amounts makes it a controversial ingredient.
Risks
Excessive fluoride can cause dental fluorosis and other health issues.
Benefits
Fluoride strengthens enamel and helps prevent cavities.
Sodium Lauryl SulfateVery Bad
Sodium lauryl sulfate (SLS) is a surfactant used to create foam in toothpaste, but it is a known mucosal irritant. It has been linked to mouth ulcers and can damage oral epithelial tissue. Its harsh nature makes it a concerning ingredient in oral care products.
Risks
SLS can cause mouth ulcers and irritation of oral tissues.
Benefits
It helps in foaming and spreading the toothpaste, though benefits are outweighed by risks.
