Tooth sensitivity occurs when dentin, the sensitive inner layer of the tooth, is exposed due to enamel erosion or gum recession, allowing external stimuli like hot, cold, or acidic foods to trigger fluid movement in dentinal tubules, irritating nerves.

Hydroxyapatite (especially micro-hydroxyapatite in ENML tablets) works by sealing these open tubules: These particles deposit on the tooth surface, fill microscopic defects, and remineralize enamel, creating a protective layer that blocks fluid flow and reduces pain. This process not only provides fast relief but also strengthens enamel long-term, preventing further sensitivity.

Sensodyne, a leading sensitivity brand, primarily uses potassium nitrate and stannous fluoride. Potassium nitrate desensitizes nerves by depolarizing them, reducing signal transmission to the brain, while stannous fluoride forms a barrier over exposed dentin to block tubules. It's often less effective for sustained relief because it focuses on symptomatic nerve soothing and temporary barriers rather than true remineralization. Relief may take weeks, and it doesn't rebuild enamel structure, potentially allowing sensitivity to return.

Hydroxyapatite in ENML is more beneficial as it's non-toxic, biomimetic (matching your teeth's natural composition), and provides faster, longer-lasting relief—studies show it outperforms fluoride-based options like Sensodyne in tubule occlusion and sensitivity reduction within days, while also whitening and preventing cavities without side effects like microbiome disruption.

Brush twice daily with ENML for noticeable improvement in 30 days, scaling your smile's health naturally.
