Once the procedure is complete, it is crucial to stick with soft foods and cool or moderately warm liquids. You do not want to disturb the special substance that is covering the gums while they are healing. You will also want to keep your mouth clean during the healing process. You will not be able to brush in the area of the gingivectomy, but you will need to brush and floss as much as possible in the rest of the mouth. It will take several weeks for the gums to heal completely. At this time you should be able to resume brushing and flossing throughout the whole mouth. It will be important, however, to be gentle in the affected area for a while.
