Attach the black tip on the syringe and remove the plunger. Then fill the syringe with a maximum of 1,5 ml blue®m oral gel and put the plunger back into the syringe. First dry with a swab the gingiva or pocket for the gel to stay in place. Leave the gel as long as possible but no longer than one hour. The gel can be applied three times a day max, after brushing and/or rinsing with blue®m toothpaste/mouthwash or as indicated by your implantologist, dentist or oral hygienist.
