Tooth Sensitivity to Cold

Have you recently had a cold drink ruined by a sensation of shooting pain in your teeth? It could be eroded enamel. We hope that all our patients at Bernstein Dental Care in Bay Ridge are enjoying summer treats, but if they’re suffering from tooth sensitivity, we can help.


The pulp chambers inside our teeth are highly sensitive. They are surrounded by dentin, a hard substance made up of tubules that easily conduct heat. Dentin is a greyish-yellow color, and although it is normally shielded by a crown’s hard enamel, it can be visible when enamel is thin. Enamel may be worn down by mechanical processes if there is a problem with the patient’s bite or if the patient is grinding their teeth, but in most cases of sensitivity, enamel has been eroded by acid. The most common source of acid is bacteria that consume food debris, although it may also be regurgitated from the stomach.


Tooth roots are surrounded by a thin substance called cementum. If the gums have receded enough for the cementum to be exposed, the underlying part of the tooth will also be sensitive. Good oral hygiene is essential for preventing tooth decay and gum recession, but if patients have already lost minerals in their enamel, they may be able to restore it by using extra-fluoridated toothpaste. They may also benefit from sealants.
