Why does a tooth react to cold?

Why a tooth reacts to cold is one of the fairly frequent search queries. Everyone knows that normally teeth should not hurt and give some kind of reaction to temperature changes. So why is there a sensitivity to cold in the tooth?

Answers dentist, chief physician of the dental clinic Ilya Antonov:

– The normal situation for a person, as well as the norm for a healthy and properly functioning tooth, is the absence of any manifestations that cause concern. Normally, we do not even notice how our organ functions – the heart, skin or the same tooth, if nothing irritates them. In adolescence and youth, we do not notice their existence at all.

And here it is worth understanding that as soon as the tooth began to show itself, this automatically means that it is damaged. And the reaction to the same cold is nothing more than a signal for help. What could have happened to him that he got sick? There are mainly two options – either caries has appeared, or a wedge-shaped defect. Only these two defects give a reaction to cold stimuli.

In both cases, this is a situation in which the enamel surface is damaged through and through and the dentin of the tooth is exposed. It is this border (enamel-dentin) that is the most sensitive area, which is the first to signal primary damage to the tooth. If left untreated, these lesions will develop into medium to deep caries.

Therefore, at the first such sensations, you need to contact the dentist and understand how urgent the situation requires treatment. In 2/3 of cases, the whole issue can be resolved by placing a filling or (if not starting the process) simply by covering the gums with a sitizer.

In any case, the painful sensation is not a normal situation, and one should not reassure oneself with the words “it will pass now”. After any acute period when pain is felt, the stage of remission begins. In this case, they say that there is an imaginary relief, a false feeling of recovery. In fact, just the body, faced with an invasion, began to signal pain. Without help, the nerve endings through which we received pain signals in the first stage die. Soreness passes, but bacteria continue their destructive activity, but now we do not feel this until they destroy the tooth even more and reach deeper tissues and nerve endings. Then the second stage of inflammation will come, characterized by large damage to the tooth and serious inflammation. And so it will continue in a circle until the tooth dies.
