Question: How much bleeding is normal after a dental procedure?
Explanation: Oozing that tinges saliva pink for up to 24 hours after an extraction is normal. A small amount of blood mixes with a large volume of saliva, which makes it look far more dramatic than it is. Concerning bleeding is a steady flow that fills the mouth within minutes, persists beyond 24 hours, or forms large jelly-like clots. First aid involves biting firmly on a rolled damp gauze or clean handkerchief placed directly over the socket for 20 uninterrupted minutes. Avoid rinsing, spitting, hot drinks, and lying flat.

What is the correct way to bite on gauze after an extraction?
Roll the gauze into a firm cylinder, place it directly over the socket rather than between the teeth, and bite with steady pressure for a full 20 minutes without checking. Repeated checking dislodges the forming clot. A damp tea bag is a useful alternative, as tannic acid promotes clotting.
Why does bleeding restart on the evening after an extraction?
The local anaesthetic usually contains adrenaline, which constricts blood vessels. As it wears off after several hours, vessels dilate and oozing resumes. This is expected. Reapplying gauze pressure normally resolves it. Persistent flow beyond this warrants contacting the dentist.
When does post-operative bleeding become an emergency?
If bleeding fills the mouth repeatedly despite 30 minutes of firm continuous pressure, if you feel faint or dizzy, or if you take anticoagulants and cannot control it. Attend an emergency dental service or emergency department. Do not simply keep swallowing blood, as this causes nausea and masks the volume lost.
