Caught cold!
Even if the current January temperatures are more reminiscent of spring, the last winter was the deepest winter. The weather forecast is now very accurate for several days, so that we can adjust in advance to wintry conditions.
This is unfortunately not the case with the teeth! Since we are sometimes caught cold when eating cold food and drinks! Out of nowhere, it stings and pulls into the tooth. A short but intense pain! Luckily, it fades after a few seconds. But what is going on there? Some of us do not have any sensitive teeth at all and others can not even consume cool mineral water! The answer is: How well are my own teeth protected from external stimuli? What hurts is ultimately the tooth nerve! But how can the tooth nerve cause pain, which lies deep inside the teeth? Yes, that’s correct, but the tooth nerve is surrounded by protective dental layers such as the dentin and enamel. And finally, it’s just the enamel of the stimuli that keeps the cold off the tooth nerve. Why is that? The dentin contains many microscopic channels (dentinal tubules) that run from one end to the other. The channels all lead into the depth of the tooth, to the tooth nerve. In every 10th channel there is even a nerve extension of the tooth nerve. This extends his feelers, so to speak. Are Denticular tubules now open and unprotected, the cold stimulus penetrates into the dentinal tubules and irritates the nerve processes in it! It hurts!
The dentinal tubules are only open and unprotected if the overlying enamel layer is missing or only very thin. People who are naturally endowed with only a relatively thin layer of enamel therefore often suffer from pain-sensitive teeth. But even people who like to take acidic drinks and food, thus reduce the thickness of their enamel layer and more often suffer from sensitive teeth! The most common reason, the classic, so to speak, is the exposed tooth neck. Here, dentin is exposed unprotected, because the protective gums at the transition from the tooth crown to the tooth root has declined for a variety of reasons. Against all these pain symptoms, there are more or less good-acting substances that are found today in special toothpastes or mouthwashes. Most of the time, there are small special particles that settle on the open dentinal tubules, blocking them, so to speak, so that the cold stimulus can no longer penetrate. In worse cases, the dentist can also apply special paints for pain relief.
In general, it can be said that pain-sensitive teeth are usually annoying but harmless symptoms. However, it is also important to clarify this during a visit to the dentist, because even a damaged tooth surface, caused for example by a carious hole, can cause similar symptoms. So it does not get you ice cold when the unloved drill is used.

Why do you need the tooth nerve at all??
What is the purpose of the tooth nerve??
A dream of many patients: never have toothache! But despite the most intensive dental care, all of us have a toothache during our lifetime. But why does it have to be that way? Why do these teeth have this nerve that can sometimes hurt so badly? Why can not teeth be like Hair or fingernails? Simply painless? Does a tooth without a nerve not work just as well? And if there should be a hole in the tooth, just drill into it without pain ?! Yes, unfortunately, many will think now, unfortunately it is not so!
Like so much on or in our body, the tooth nerve in biological evolution has been found useful! What should be useful on a painful tooth, some now think! Well, the most important function of the nerves in the human organism and there the tooth nerve is no exception, is the perception of pain. Pain has the task of warning the body! It threatens mischief in the form of illness or injury! So it’s a protective function. Even the tooth might want to warn about toothache: “There’s a hole in me, better take care of me”! Unfortunately, this warning comes at low holes at least, usually too late. Then the caries bacteria have already arrived on or in the tooth nerve, a root canal treatment is necessary in many cases! And the tooth nerve then “dead”.
It is also important that the tooth nerve warns against too hard food. If we bite, for example without warning on a pepper or grist, that hurts! Through a reflex we open your mouth immediately! This protects the tooth from mechanical damage.
However, the most important protective function of the dental nerve is that it produces dentin throughout its lifetime. Dentin, or dentin, is the second tooth hard substance and found under the enamel. So the nerve can try to defend itself from caries holes by creating new dentin. Even if you eat a lot of hard or raw foods food and thus the wear of the teeth is large, the tooth nerve can form new hard tooth tissue inside. Thus one can use his teeth longer than chewing tools.
Not so unwise this invention of nature.
