Most people know about winter health, but do not know that our teeth also need to be protected in winter. Experts pointed out that the cold and dry winter, easy to induce oral diseases, and teeth is one of the “victims”. These two days there is another wave of cold air, the cold index is getting higher. Mr. Wang drank a lot of cold beer when he ate hot pot the other day, and that night his teeth felt, like summer with teeth biting a popsicle, feeling chilly, more than two days, no improvement. Generally speaking, the main cause of toothache is oral disease, such as tooth decay, acute pulpitis, periodontitis, hidden tooth fracture or root fracture, etc. The toothache caused by tooth decay is because there is a cavity in the tooth, and it feels toothache when it encounters cold, hot, sour, sweet and other stimuli or food embedded in the cavity, and the toothache can be stopped immediately after removing the stimulus, but the toothache symptom will be increased. The toothache caused by acute pulpitis is manifested as spontaneous and paroxysmal pain, and the pain is intensified when encountering hot or cold stimulation or resting at night. “The toothache caused by other etiologies has different mechanisms, but one thing is common, that is, the pain increases when encountering cold or hot stimuli.” Dr. Xu said. In winter, when people breathe air in cold weather, their teeth are also indirectly exposed to cold air. Especially when you have a cold and nasal congestion, your teeth are more in contact with cold air, which naturally tends to cause toothache. Of course, heat stimulation is also likely to cause toothache, such as eating while hot, especially when hot and cold alternately, the incidence of toothache will be greatly increased. Eating habits are also related to dental health In addition to weather causes, experts warn that other elements of winter, such as humidity, wind and sunshine, also have a direct or indirect impact on toothache. “Winter is the off-season for vegetables, and the air is dry, so people tend to get “on fire” and get toothaches.” Especially in winter, people love to eat hot food, hot and cold mixed food and other such bad habits can also induce dental discomfort. The spicy pot can irritate the teeth and is the “number one killer” of acute pulpitis. People with no dental problems can eat hot, cold, sweet and sour whenever they want. If you have a toothache from eating hot pot, you must be a patient with dental disease. Especially if you have a dental disease that causes deep holes in your teeth, once you are exposed to too hot, too spicy food, it is extremely easy to trigger a toothache. Not only eating hot pot, but all kinds of stimuli such as too cold and too acidic can easily cause toothache. For example, if you brush your teeth in the morning in winter when the water temperature is too low, you will also have a painful fall. In addition, the main cause of acute pulpitis, periodontitis, tooth pain and other patients in winter is due to a mixture of hot and cold food. Many people eat spicy pot is very addictive, eat hot and spicy, usually at the same time will order some cold beer, drinks, some people are not enough to enjoy, but also eat ice cream, so hot and cold food, it is easy for patients with tooth decay or periodontal disease, due to excessive wear and tear of the dental pulp and injury to the root, resulting in a hot and cold food or drink stimulation, will produce a pain or pain like pins and needles. The “hard bone” grinding bad teeth eating seafood pot dental problems, mainly due to bite shrimp and crab shells, resulting in punctures, bite broken decay parts or dentures to seek medical advice. Many people in the soup or hot pot, food is not cooked too bad, teeth bite too hard food, on the one hand, easy to cause dental defects, on the other hand, easy to cause bite trauma, these are one of the causes of pulpitis, periapical disease. Warm tip: In winter, you need to take good care of your dental health, avoid hot and cold stimulation, prevent dryness and bacterial infection that induces periodontitis, gum bleeding, etc. Teeth are sensitive to temperature, usually below 10 degrees Celsius or above 50 degrees Celsius, the teeth will react, which may lead to pulp lesions, so it is best to rinse your mouth with warm water. From the outdoor into the house, due to the temperature contrast, do not immediately drink too hot and too hot water, otherwise prone to allergy symptoms. In addition, the scientific choice of toothpaste, such as alternate use of fluoride and anti-allergy toothpaste, can reduce the chance of tooth sensitivity and also prevent tooth decay.
