When plugged teeth, treatment measures such as probing, application of smooth turning needle, grinding away decaying tooth tissue and making inlays can be taken as follows: i. Application of probing: food residue and soft scale inside the teeth can be removed by applying probing needle or toothpick, and food fibers can also be removed with the help of dental floss or flosser. Second, the application of smooth car needle: you can adjust and grind the cusps or marginal ridge of the jaw filling type to reduce food embedding, after the application of smooth car needle to extend the outreach gap, food is easier to discharge. Wear out the decayed tooth tissue: When the tooth adjacent surface forms caries, you can wear out the decayed tooth tissue and repair it with composite resin to restore the good adjacent relationship. 4.Make inlay: When the gap between teeth is large, inlay can be made to close the gap, and if necessary, metal or all-ceramic joint crown can be made after tooth preparation.
