In our daily life, many people have encountered the problem of eating stuffed teeth, which is medically called “food impaction” and mainly occurs in middle-aged and elderly people, especially in the elderly population is more common. Food embedment can be divided into two types: one is horizontal embedment, and the other is vertical embedment. Horizontal embolism is the gingival papilla between two teeth, with age, or due to disease damage and atrophy, resulting in the exposure of the space between the roots of the teeth, when chewing, some soft food debris is squeezed into the space, resulting in the so-called food embolism, these food debris without squeezing force, usually simply rinse the mouth that can remove food debris. Vertical embedding is food from the occlusal surface by strong chewing pressure wedged into the gap, usually some fiber-rich, tough food, can produce a great squeezing force, so that people feel very uncomfortable; because the plug is very tight, not easy to take out, you must use toothpicks, dental floss and other tools to carefully pick, pick, to take out. Because of its great pressure, long time embedded often cause the destruction and absorption of alveolar bone, so that the root gradually exposed, and chronic inflammation, coupled with the stimulation and injury of toothpicks, gums in a long-term inflammatory state, not easy to recover, resulting in the loosening and displacement of teeth. In the past, due to the limitations of the conditions, there were not many clinical solutions for food blockage; nowadays, with the development of dental medical technology, there are many clinical solutions for food blockage, such as movable food inlay, inlay, full crown, etc., which can help you solve most of the problems of food blockage.
