You can drink milk after gingivectomy. Gingivectomy is a procedure that removes enlarged gum tissue and restores the normal anatomical shape of the gums. For 24 hours after gingivectomy, you will need to eat some semi-liquid or soft food, so it is possible to drink milk, and if you consume soft food you should only chew on the non-surgical side. After gingivectomy, it is important to keep plaque under control as plaque can interfere with tissue healing. For the intraoperative area, mouthwash is optional, while for the non-operative area, plaque can be removed by normal brushing. Meanwhile, you should not eat overly hot food for about 1 to 2 days after the surgery to avoid stimulating the gums to bleed. After waiting for a week, you can resume your normal diet. It is recommended to see your doctor regularly for review after gingivectomy and to seek medical attention if there is any discomfort in the mouth.
