Oral sprays are generally referred to as stomatitis sprays, and it is recommended to use stomatitis sprays about 24 hours after tooth extraction. The main ingredients of stomatitis spray are honeycomb, dandelion, saponaria, and lonicera, which can be used for the treatment of stomatitis, oral ulcers, pharyngitis and other diseases, and its adverse reactions and contraindications are not clear. It usually takes 15-30 minutes for bleeding to stop in the wound after tooth extraction, a few hours for the gum tissue to contract to protect the blood clot, and 24 hours for the wound to begin early healing. If stomatitis or oral ulcers exist in the mouth and require stomatitis spray treatment, it is recommended that it be used 24 hours after extraction to avoid irritating the extraction wound and affecting its healing. The medication needs to be used under the guidance of a doctor, and it is recommended to visit a hospital to receive regular treatment.
