Often, our teeth become temporarily or permanently sensitive to external influences.
This usually manifests itself as a sudden sharp pain in one or more of our teeth in response to the consumption of cold, hot, sweet, salty foods, drinks or cold air. It is also not uncommon that brushing causes pain.
There are several possible causes of this sensitivity, but they all have in common that the dental pulp (pulp, nerve) comes into contact with the oral cavity through tiny canals. These canaliculi, which run in the dentine, are usually sealed by enamel, radicular cementum and gingiva. The openings of the tiny canaliculi may become free when the tooth becomes decayed, the enamel wears down or the gums recede.
In any case, it is worth seeking the help of a dentist who can prepare a filling or treat gingivitis. Often, brushing gently but thoroughly will solve the problem. Use a soft toothbrush (e.g. Curaprox 5460) and a toothpaste with ingredients that can block, seal small dentinal canaliculi (toothpastes for sensitive teeth). Be sure to try to solve the problem, because the tooth can become inflamed because of all the external stimuli.
