It should be a split spring on the top of the big tooth, which separates the big tooth from the next tooth. When wearing braces, you should wear a ring when you punch your teeth.

The front teeth highlight crowded dentition. In order to have room to put the front teeth in, doctors often take the method of tooth extraction or slicing. Slice cutting is to cut off a part of the tissues on both sides of the teeth, so that there is a gap between the teeth, through which the front teeth are adducted, but this will do some harm to the teeth, because the protective layer of the teeth is worn away, even if it is not completely removed, it will be sensitive to external stimuli or easy to rot in the future. Talk to the doctor again. There is no other way but this one. Here's to health!
