When the bone residue is stuck in the teeth, there are the following methods: 1, use a toothbrush with long bristles, stick the bristles into the adjacent gap of the teeth and the gingival sulcus, turn the brush head up and down so that the bristles hook the bone residue and bring it out; 2, use a toothpick or a gap brush to reach into the gap of the teeth to take out the bone residue; 3, press the dental floss into the teeth below the adjacent point, lift up and down along the adjacent surface of the teeth and bring out the bone residue; 4, use a flosser to rinse with pressure against the embedded part of the teeth, using the water to flush out the tiny residue; 5, go to the hospital as soon as possible to remove the bone residue by the doctor, and disinfect the bleeding, red and swollen gums, and take oral anti-inflammatory drugs to prevent infection if necessary.
