You may experience some pain and soreness after a gingivectomy that makes it difficult to eat foods with a medium to hard texture or acidity. Your dentist will recommend eating soft foods to lessen irritation and avoid damaging your gums as they heal during the week following your gingivectomy. You should also avoid tomatoes, and acidic fruit such as pineapple, lemons and limes. Tooth paste can also be irritation for that first week following the gingivectomy.
