Many people unknowingly use toothpaste that’s too abrasive, thinking it leads to a brighter smile. However, excessive abrasiveness can gradually erode enamel, cause gum sensitivity, and damage dental work. This article explores what toothpaste abrasiveness really means, how to assess your current brand, and why pairing a smart toothbrush like BrushO with the right toothpaste offers a safer, more effective oral care solution.

Toothpaste contains abrasive agents—such as hydrated silica or calcium carbonate—to help remove plaque and surface stains. While mild abrasiveness is necessary, excessive levels can:
• Erode enamel over time
• Expose dentin, leading to sensitivity
• Damage restorative dental materials like veneers or crowns
The Relative Dentin Abrasivity (RDA) scale measures how harsh a toothpaste is. A score under 70 is considered low-abrasive and gentle enough for everyday use. Some whitening or smoker’s toothpaste brands exceed 150 on the RDA scale, which can be damaging if used frequently.
You might not immediately notice enamel erosion, but there are signs to watch for:
• Increased tooth sensitivity, especially to cold or sweet foods
• Gum recession not caused by brushing technique
• Dull or yellowing teeth, ironically caused by enamel thinning
• Visible notching near the gumline (called cervical abrasion)
These symptoms often develop slowly, so proactive awareness is key.
Even with a non-abrasive toothpaste, aggressive brushing can still cause damage. That’s where BrushO’s smart technology steps in:
BrushO alerts you when brushing pressure exceeds safe levels, protecting enamel and gums from friction damage.
Modes like Ultra-Gentle and Gum Care are ideal when using whitening toothpastes or treating sensitivity.
Heatmaps and brushing reports highlight overbrushed areas, helping users maintain balanced pressure and coverage. Combined with a low-abrasive toothpaste, BrushO helps you clean more effectively—without harming your teeth.
Here are safe guidelines when selecting a toothpaste:
| RDA Score | Abrasiveness | Recommendation |
| 0–70 | Low | Ideal for daily use |
| 70–100 | Medium | Use cautiously |
| 100–150 | High | Occasional use only |
| 150+ | Harmful | Avoid unless advised by a dentist |
Look for products labeled low abrasion, especially if you have veneers, crowns, or gum sensitivity.
