Summer is coming, and some teenagers are unable to enjoy the taste of cold drinks because of tooth decay, periodontal disease and other problems. What are the most common oral diseases for teenagers in summer? Caries In summer, people like to eat cold drinks, and the strong cold stimulation can make the more serious caries painful, then if not treated, it may cause a series of complications such as dental pulp disease, periapical disease, jaw bone inflammation and interstitial infection. At the same time, eating too many cold drinks can aggravate the dentin sensitivity caused by various reasons. Therefore, dental caries should be treated in time. Periodontitis When there is bleeding, redness and swelling of gums, loose and shifted teeth and weakness of chewing, it indicates that periodontitis already exists. In summer, the day is long and the night is short, people lack of sleep and appetite, and the body resistance decreases, which provides favorable conditions for further development of periodontitis or even acute attack. Once the above symptoms appear, you should seek medical attention promptly. More importantly, prevention is the main focus, with good oral hygiene habits, regular oral examination. Dental disease seems to be a “minor problem”, but the attack is really “deadly”, it will affect the eating, mood, and serious threat to the function of the heart, brain, kidneys and other important organs. What should teenagers do to maintain their teeth and oral health? First of all, control the plaque. The common factor that causes caries and periodontal disease is plaque. Plaque is actually a kind of biofilm, they are biological colonies composed of a large number of different types of bacteria, very dense. They are hidden beneath a thin mucous coating, especially in areas that are difficult to reach with toothbrush bristles, making removal more difficult. From a preventive point of view, plaque removal is the key to maintaining oral hygiene. Regular brushing habits should be improved to remove plaque in a timely and effective manner. The easiest way to remove plaque is to rely on proper brushing methods and suitable brushing tools. The use of electric toothbrushes and flossing have become effective ways to remove biofilm plaque. When brushing manually, brush for at least 2-3 minutes each time, once a day in the morning and once a day in the evening, not only to brush your teeth but also to clean your gums and oral mucosa. In addition, the use of dental floss to clean the adjacent gap between the teeth, you can clean the toothbrush can not clean the “dead space”, if possible, you can also use the gap brush to clean the gap between the teeth …… Second, keep your breath fresh. No one likes to smell bad breath. To prevent bad breath, you must first pay attention to oral hygiene, insist on brushing and flossing every morning and evening, and don’t be afraid of trouble. Many bacteria will not only choose the gaps between teeth as a place to live, but will also make their home on the tongue, which is easily overlooked. A daily cleaning with a tongue scraper can clean this area. In addition, gargling with warm water after meals can rinse out any food residue left in the mouth. In ancient times, our country advocates gargling with tea, which is a good way because tea contains fluoride and tea polyphenols, which can prevent tooth decay and is also good for preventing gingivitis. It is recommended to check whether there are caries and periodontal disease in dentistry every six months, and do ultrasonic cleaning if necessary. Thirdly, pay attention to reasonable diet. If the bacteria in the dental bacteria act with sugar, it will induce tooth decay. It is recommended to eat less sugar. Smoking, drinking alcohol, drinking coffee, black tea and spicy and stimulating foods such as onion and garlic are also avoided as much as possible. On one hand, they tend to cause bad breath, and in addition, frequent smoking, drinking coffee, black tea, etc. are also the reasons why teeth are easily stained.
