Retraction cord has different sizes and sometimes the dentist uses a double layer of cord.
This diameter is the part that goes around the tooth.
However, it can sometimes cause side effects and minor injury, particularly in those with gingivitis.

A gingival retraction cord can sometimes cause bleeding as the cord rubs against the gum.
Gum bleeding can be difficult to control and, in turn, make impressions hard to capture.
Many dentists prefer to soak the gingival retraction cord in Hemodent themselves, rather than having pre-soaked cords.
Others find Hemodent unnecessary in anyone with otherwise healthy gums or teeth.
