About two hours after tooth extraction, you can use liquid or semi-liquid food, such as noodles, rice porridge, thin rice, juice, etc., mainly because this kind of food does not require excessive chewing and generally does not cause irritation to the affected area. It is important to avoid spicy, stimulating, greasy, too hot and too hard foods to avoid inducing bleeding and infection. In addition to diet, attention should be paid to the maintenance of oral hygiene after tooth extraction. 24 hours after tooth extraction, teeth can be brushed and mouth rinsed to avoid retention and fermentation of food residues. If there is local infection or obvious pain, it is recommended to actively seek medical examination and take anti-inflammatory and pain-relieving drugs under the guidance of the doctor, and generally resume normal diet about a week after tooth extraction.
