Toothpaste Testing Lab Services
Toothpaste Efficacy & Microbial Testing
- Whitening Efficacy and Stain Removal : This test is carried out to evaluate how effectively the toothpaste removes surface stains and improves tooth brightness. Outcome of this test helps to determine shade improvement, stain removal efficiency, and polishing effect. Instrument such as spectrophotometer lab, laser surface profilometer are used to derive at ΔE (color difference), % stain removal efficiency, and polishing score.
- Antimicrobial & Biofilm Inhibition : We test for effectiveness of toothpaste against oral bacteria and plaque biofilm formation is analyzed. The outcomes highlight bacterial reduction, inhibition of biofilm growth, and plaque control efficiency. Microbial culture methods, confocal microscopy, and staining assays are used to quantify antibacterial performance.
- Foaming, Flavor & Mouthfeel Studies : The tests are conducted to examine foam formation, texture, and sensory acceptability during brushing. Outcomes capture foam stability, viscosity, and user perception of taste and mouthfeel. Foam analyzers, rheometers, and trained sensory panels are utilized to ensure a balanced and pleasant brushing experience.
Abrasion & Cleaning Performance Testing
- Relative Dentin Abrasivity (RDA) : Nanowatts conducts routine RDA In Vitro study to examine how much dentin is worn away during brushing with the toothpaste formulation. Results provide a standardized RDA value that indicates whether the product is within safe limits for daily use. Instruments such as V8 cross brushing machines, optical profilometer techniques are used for measurement. Visit our RDA and Toothpaste Abrasivity testing lab.
- Relative Enamel Abrasivity (REA) : The aim of this test is to evaluate enamel wear or surface damage that may occur from brushing. Findings help balance cleaning power with enamel protection. Optical profilometers and surface roughness analyzers are typically employed to assess abrasion level.
- Pellicle Cleaning Ratio (PCR) : We carry out PCR test to find toothpaste’s ability to remove stains from the tooth surface under controlled conditions. Outcomes highlight stain removal efficiency and whitening contribution. We often use spectrophotometer and digital imaging systems to calculate PCR values and visualize improvements.
- Dentin Surface Topography : We employ in house surface topography tools to do 3D mapping of enamel or dentin before and after brushing cycles. Results identify changes in roughness, polish effect, or surface wear. Optical profilometers and 3D surface scanners are used here for high-resolution surface analysis.

Toothpaste Material Analysis
Toothpaste Sensitivity and Enamel Studies
- Dentinal Tubule Occlusion (Sensitivity Relief Testing) : This In Vitro study evaluation focuses on how effectively the toothpaste formulation blocks exposed dentine tubules to reduce tooth sensitivity. The outcome results in the percentage of tubule occlusion, depth of mineral or particle penetration, and durability of the desensitizing effect after brushing or rinsing. Scanning electron microscopy (SEM), confocal imaging, and hydraulic conductance systems are used to visualize and quantify occlusion. .
- Smear Layer Interaction Studies : We perform this to study to understand how toothpaste formulations interact with the dentinal smear layer formed during brushing or abrasion. Results show whether the formulation preserves, modifies, or removes the smear layer, which directly impacts dentine permeability and sensitivity. Analytical tools such as SEM, EDS, and optical microscopy are applied to observe surface morphology and compositional changes.
- Ion Loss and Mineral Leaching Evaluation: We perform this In Vitro assessment to find released or loss of essential ions such as calcium, phosphate, or fluoride from enamel or dentin after brushing with a specific toothpaste. The results help determine whether the product promotes remineralization or contributes to mineral depletion over time. We employ SEM-EDAX, IES, ICP MS to understand ion loss.
