What Causes Tooth Sensitivity?Aug 22
Aug 22
Tooth sensitivity causes are more common than you think—millions of people experience sharp discomfort when eating ice cream, drinking coffee, or even brushing their teeth. This sensitivity often results from enamel erosion, gum recession, or over-brushing. In this article, we’ll explain the key reasons behind tooth sensitivity, what daily habits make it worse, and how smart electric toothbrushes such as BrushO can protect your teeth and gums for long-term relief.
The Science Behind Tooth Sensitivity
Tooth sensitivity occurs when the dentin—the inner layer beneath the enamel—becomes exposed. Normally, enamel acts as a shield, but when it wears down or gums recede, the dentin’s microscopic tubules allow hot, cold, or acidic sensations to reach the nerves inside your tooth. This is why even a sip of iced water can feel painful if your teeth are sensitive.
Common Causes of Tooth Sensitivity
1. Enamel Erosion
Enamel can weaken due to:
- Frequent consumption of acidic foods or drinks (soda, citrus, wine)
- Grinding teeth at night (bruxism)
- Overzealous brushing with hard bristles
2. Gum Recession
As gums recede—either from age, gum disease, or aggressive brushing—roots become exposed. These root surfaces have no enamel, making them more sensitive.
3. Over-Brushing
Ironically, brushing too hard or using a stiff-bristled manual toothbrush can strip enamel and irritate gums. This is one of the most overlooked reasons for sensitivity.
4. Dental Treatments
Recent whitening procedures, fillings, or orthodontic adjustments can temporarily increase sensitivity.
