Since some time ago, my teeth have become excessively sensitive when drinking cold water. Even after the water passes down my throat, I still make a face for a while. It's not just because of age; it could be due to damaged teeth caused by improper brushing habits.

 

Tooth sensitivity is a sign that your dental health has deteriorated. When the nerves inside the tooth are stimulated, the tooth becomes sensitive. Teeth are composed of the hard outer enamel and the dentin beneath it, which has a yellowish hue. The dentin contains tiny, invisible holes called dentinal tubules. Since these holes are connected to the nerves, when the enamel wears down and the dentin is exposed, the nerves are also stimulated.

The main cause of enamel erosion that makes teeth sensitive is 'poor brushing habits.' A typical example is brushing too hard against the teeth with a toothbrush. Frequently drinking carbonated beverages or grinding teeth while sleeping also causes enamel to wear down. Chewing ice or candies without melting them also has an impact. The habit of clenching teeth when concentrating applies physical force to the teeth, accelerating wear, so caution is advised.

 

To prevent cavities, start by changing your brushing method.

Do not move the toothbrush side to side; instead, brush in a sweeping motion towards the teeth with the toothbrush bristles and gums forming a 45-degree angle. It is good to sweep each tooth about 20 times.

Hold the toothbrush lightly with your fingers instead of your palm to avoid putting too much effort.

 

If your toothache is severe, you can receive treatment at the dentist. This involves filling the worn part of the tooth with a filling material to prevent the dentin from being exposed externally. It also involves blocking the holes in the dentinal tubules by combining fluoride or other substances with calcium inside the tooth.

 

Using toothpaste specifically designed for sensitive teeth can be somewhat helpful. Sensitive toothpaste contains particles that can block exposed dentinal tubules. However, sensitive toothpaste may have weaker plaque removal performance. If you brush three times a day, it is recommended to use sensitive toothpaste twice and regular or tartar control toothpaste once for better dental hygiene management.

 

==========

I never thought about whether there is a toothbrush to prevent cavities.

Brush your teeth as if sliding down.

Don't hold it with your palm, hold it with your fingers.

It's good to catch the spray.
