In recent years, more and more middle-aged and elderly patients come to the hospital because of “blocked teeth”, most of them will say that there is always food residue embedded in the teeth after eating, very uncomfortable, must be removed by toothpicks and other sharp tools at the end of the head to do, at first do not care too much, think that the clean out on the line, but over time the gap is bigger, the gums also become The gums become red and swollen, and sometimes there are symptoms such as swelling and pain. Is it normal to have “blocked teeth” often? Why? What should we do to effectively prevent it? “In medical terms, it is known as food impaction, i.e. during chewing, food is wedged into the space between two adjacent teeth by biting pressure. Depending on the way of embedding, it is clinically classified into vertical and horizontal embedding. There are many causes of food impaction, including congenital and acquired factors, the most common of which are as follows. The “worm teeth” between neighboring teeth, have you found it? In our daily life, we routinely brush our teeth and rinse our mouth after eating every day, but have you cleaned between the teeth that are closely adjacent to each other? If not, the food residue left between the teeth can provide a perfect breeding ground for the ubiquitous bacteria, and “worm teeth” will slowly begin. If not taken seriously and allowed to develop, the normal dental tissue between adjacent teeth is destroyed, making the gaps larger and causing congestion. At this point, grandparents should be careful and must go to the hospital for examination, and the dentist will choose the appropriate filling or restoration method according to the situation. Some people due to congenital factors teeth wrong front and back, alignment is not neat; there are people due to acquired causes of tooth twisting, which makes it more difficult to clean our teeth, some people will use a variety of auxiliary tools such as electric toothbrushes, tooth gap brush, etc., despite this, still can not avoid the occurrence of gingivitis and periodontitis. In the long run, it will cause the gap between the teeth to become larger, which will easily lead to dental congestion. In this case, we have to consult a professional doctor, according to the specific situation to choose extraction, orthodontics and other treatment; individual tooth loss In the past, the elderly individual teeth lost, will not cause enough attention, so they habitually chew with the opposite side, over time, the missing teeth on both sides of the adjacent teeth to the middle tilt shift, resulting in the gap between the two sides and multiple teeth, resulting in dental congestion. Nowadays, life is getting better and better, people’s knowledge level is also improving, and they are more concerned about oral health. All missing teeth will go to the dental hospital for restoration treatment as early as possible. If both sides of the teeth are tilted toward the gap, orthodontic treatment is needed to put the tilted teeth upright to eliminate the gap before restoration treatment. Excessive loose teeth In recent years, there are more and more loose teeth due to various reasons such as severe periodontitis, trauma, etc. These loose teeth have poor contact with neighboring teeth, and if not treated in time, the gap between the teeth will increase, causing tooth blockage. For such cases, the cause of the loosening should be clarified first and then treated conservatively as far as possible, and teeth that are determined to have no retention value should be extracted, and those that can be retained should be treated accordingly by eliminating local inflammation and fixing the loosened teeth. The annoying wisdom teeth Normal teeth grow like trees, but most wisdom teeth are unique and have to grow horizontally or diagonally. This position causes a wedge-shaped gap with the immediately adjacent teeth, resulting in a blockage. There are also some wisdom teeth that are wildly elongated due to the absence of a synergistic relationship, which can aggravate food impaction and cause local inflammation during every chewing session. In this case, wisdom teeth should be extracted when there is no acute local inflammation. Finally and most importantly, “stuffed teeth” is important for effective prevention, we usually can not be lazy. You should brush your teeth in the morning and evening, rinse your mouth after meals, choose fluoride toothpaste, use a suitable toothbrush, and use dental cleaning aids correctly to keep your mouth clean. It is also necessary to clean teeth regularly (generally once every six months to once a year) and have regular checkups to achieve early detection, early diagnosis and early treatment, so as to maintain oral health and improve the quality of life.
