Whether the sutures used for wisdom tooth extraction are black or not, you need to ask the doctor who removed the wisdom tooth for the patient. The common non-absorbable mousse thread is basically black, but there are many types of absorbable threads that are not black, for example, the commonly used clinical thread, which is a relatively good absorbable thread, is transparent, so it looks colorless. There are also different colors of sutures produced by different companies. It is common to see different colors of sutures, such as purple or blue, that are absorbable, so we need to consult with the doctor who will remove the wisdom teeth of the patient for the specific color of suture.
