This is a sensitivity-relief and cavity-protection toothpaste formulated with potassium nitrate to soothe nerve endings and sodium fluoride to strengthen enamel, using a gentle SLS-free formula.
The high performance rating of 9.1/10 is justified by the inclusion of clinically proven active ingredients. Potassium nitrate (5%) is highly effective at reducing tooth sensitivity by calming nerve activity, while Sodium fluoride (0.24%) provides essential cavity protection and enamel remineralization. Additionally, Hydrated Silica acts as a mild abrasive for plaque removal, and Sodium Tripolyphosphate aids in preventing tartar and surface stains for a comprehensive clean.
The safety rating of 8.6/10 is strong, primarily because this formulation excludes Sodium Lauryl Sulfate (SLS), replacing it with gentler surfactants like Cocamidopropyl Betaine and Sodium Methyl Cocoyl Taurate to minimize oral irritation and canker sores. However, the presence of Titanium Dioxide (used for whitening the paste itself) and PEG-8 may raise mild preference concerns for some health-conscious consumers, slightly limiting a perfect score.
An overall rating of 8.9/10 reflects a well-balanced, high-quality formulation that excels in both therapeutic efficacy and consumer safety. By pairing proven anti-sensitivity and anti-cavity agents with gentler, non-SLS foaming alternatives, this toothpaste offers an excellent daily-use option for those with sensitive teeth who do not want to compromise on cavity prevention or ingredient safety.
This formulation is an excellent, well-balanced toothpaste designed specifically for individuals suffering from tooth sensitivity and seeking daily cavity protection. The star active ingredient is potassium nitrate (5%), which is clinically proven to relieve dentin hypersensitivity. It works by penetrating the micro-channels of the teeth to reach the nerves inside, effectively desensitizing them and blocking pain signals caused by hot, cold, sweet, or acidic triggers. Combined with sodium fluoride (0.24%), which strengthens tooth enamel and aids in remineralization, this paste provides a solid defense against tooth decay while ensuring your teeth remain comfortable during daily meals. One of the standout features of this ingredient profile is its SLS-free formulation. Sodium Lauryl Sulfate (SLS) is a common foaming agent that can cause mucosal irritation, dry mouth, and painful canker sores (aphthous ulcers). By replacing SLS with gentler surfactants like cocamidopropyl betaine and sodium methyl cocoyl taurate, this toothpaste delivers a pleasant foaming experience without irritating the sensitive soft tissues of your mouth. This makes it an ideal option for anyone with a delicate oral microbiome, chronic mouth sores, or geographic tongue. For cleaning and aesthetic maintenance, the paste utilizes hydrated silica, a mild abrasive that gently polishes the teeth and removes daily plaque without damaging vulnerable dentin or thin enamel. It is paired with sodium tripolyphosphate, a powerful anti-tartar agent that helps prevent new stains from adhering to the teeth, offering a subtle whitening effect without the need for harsh bleaching agents or high RDA (Relative Dentin Abrasivity) values. Humectants like glycerin and sorbitol keep the toothpaste from drying out, while xanthan gum provides a smooth, cohesive texture. Overall, this toothpaste is a highly effective, therapeutic option for everyday use. It addresses the root cause of tooth sensitivity while offering standard anticavity benefits and mild stain prevention in a formula that respects the mouth’s natural barriers. For best results, it should be used consistently twice a day, as potassium nitrate requires a few weeks of continuous application to build up protective desensitizing barriers on the nerves and provide lasting relief from future painful episodes.
🧪 Potassium nitrate / 硝酸钾
Purpose: Desensitizing agent.
Concerns: Generally safe when used as directed in toothpaste, but should not be swallowed.
Notes: Helps reduce tooth sensitivity by calming the nerves in the teeth.
🧪 Sodium fluoride / 氟化钠
Purpose: Anticavity agent.
Concerns: Can cause dental fluorosis in children if swallowed in excessive amounts.
Notes: Strengthens tooth enamel and promotes remineralization to prevent decay.
🧪 Hydrated Silica / 水合硅石
Purpose: Abrasive / Polishing agent.
Concerns: High abrasiveness can wear down enamel over time if brushed too hard, but hydrated silica is typically safe.
Notes: Helps physically remove plaque and surface stains for cleaner teeth.
🧪 Glycerin / 甘油
Purpose: Humectant.
Concerns: None.
Notes: Retains moisture to prevent the toothpaste from drying out and improves mouthfeel.
🧪 Sorbitol / 山梨糖醇

Notes: Helps maintain product moisture and adds a pleasant sweet taste.
🧪 PEG-8 / 聚乙二醇-8
Purpose: Humectant and binder.

Notes: Acts as a solvent and helps stabilize the formulation.
🧪 Cocamidopropyl Betaine / 椰油酰胺丙基甜菜碱
Purpose: Surfactant / Foaming agent.
Concerns: Can occasionally cause mild contact allergies or irritation in sensitive individuals.
Notes: A gentler alternative to Sodium Lauryl Sulfate (SLS) that helps create foam to distribute ingredients.

Purpose: Thickener and binder.
Concerns: None.
Notes: Provides the desired viscosity, keeping the solid and liquid ingredients well-mixed.
🧪 Sodium Hydroxide / 氢氧化钠
Purpose: pH adjuster.
Concerns: Corrosive in pure form, but neutralized and completely safe in the final formulation.
Notes: Balances the acidity of the toothpaste to ensure it is gentle on mouth tissues.
🧪 Sodium Tripolyphosphate / 三聚磷酸钠
Purpose: Anti-tartar and chelating agent.
