Oral health in winter at the people living in the Arctic circle and at the sports athletes who engage in winter sports often suffer from the harmful effects of cold air, which is inhaled in lungs through an open mouth in frosty weather. In particular, biathletes, skaters, mountain climbers, mountain rescuers, military personnel and residents often spend a long time in the cold and breathe with their mouths open, especially during intense physical activity. The fact is that they almost always experience a lack of oxygen. In these conditions, intensive inhalation of cold air with an open mouth "full chest" quickly cools the teeth and gums, causing a feeling of aching and pain in the teeth. And prolonged and / or repeated cooling and supercooling of teeth damages their enamel, contributes to the development of caries, gingivitis and complete destruction of teeth. It is shown that polar explorers who studied the Arctic and Antarctic in frosty weather sometimes had their teeth not just crack from the cold, but explode right in their mouths. It is also known such a phenomenon as toothache, which occurs due to excessive local cooling of the teeth when inhaling frosty air with an open mouth. It is shown that the feeling of pain and aching in the teeth and / or gums occurs in the cold in those whose teeth and gums are very sensitive to cooling. However, there are no shelters for teeth that allow them to keep warm in the cold.

The purpose of this study is to study the dynamics of local temperature of teeth in humans when inhaling cold air with an open mouth in frosty weather and develop a special "winter" sticker for teeth.
