The following treatments can be performed when something is stuck in the middle of the tooth: 1. Use a probe or a smooth toothpick to remove the food residue embedded in the tooth space. 2. Nylon floss can be applied to enter the adjacent space vertically downward from the jaw surface and lift it repeatedly along the distal or proximal middle tooth surface to finally bring out the foreign body. 3. 4. The interdental brush can be inserted into the interdental space and its head can be rotated to remove the retained foreign matter.
