It is normal to have bloody saliva all the time after tooth extraction, but at the same time there is persistent bleeding that needs prompt medical attention.
1. Bloody saliva after tooth extraction is normal for a period of time after tooth extraction. After tooth extraction, patients should gently bite the cotton ball or gauze placed in the wound for 5~10 minutes, which can effectively stop bleeding and prevent saliva from soaking into the wound, which will help the blood clots in the wound to coagulate and promote wound healing. Be careful not to take it out too late to prevent the cotton ball or gauze roll from stinking and increasing the chance of infection.
2. If the patient has a large wound after tooth extraction, it is normal to have blood in the saliva for 1~2 hours after tooth extraction, and there is no need for the patient to do too much treatment, and the wound healing needs to be closely observed. Do not brush your teeth, rinse your mouth, lick the extraction wound with your tongue or suck the extraction wound to avoid destroying the blood clot or contributing to the infection and affecting the wound healing.
If the patient has a lot of bloody saliva or bleeding after tooth extraction, he/she should go to the regular hospital in time to avoid self-treatment.
