First of all, we need to understand why teeth get sensitive. Over time, the protective outer layers of our teeth can wear away, causing the dentin (small tubes with sensitive nerve endings running through them) to be exposed. This causes sensitivity to hot and cold, and can cause the chilly temperatures of winter to make your teeth perpetually painful.
Solutions? The first line of defense can be a good toothpaste designed for sensitive teeth. There are several on the market, and with consistent use over time, the potassium nitrate in the toothpaste can actually block up those sensitive tubes, thus creating a barrier between your teeth and the cold.
You should also check the way your brushing. Soft-bristled toothbrushes are best, and you should not brush so vigorously that you’re “scrubbing” your teeth. This can cause the enamel to wear away more quickly and can also cause problems with receding gums.
If remedies at home don’t work, you can also ask your dentist for a more permanent solution. Dentists can offer painted-on barriers that reduce tooth sensitivity, such as fluoride varnish or even resin.
