✅ Why Does Bleeding Occur After a Tooth Extraction?
When a tooth is removed, a small wound remains in the bone and gum. The body responds by forming a blood clot, which acts as a natural “bandage.”
This blood clot is essential for healing.
If it does not form properly or is disturbed, bleeding may continue longer than expected.
Common reasons for prolonged bleeding include:
▪️ Rinsing or spitting too soon
▪️ Touching the area with the tongue or fingers
▪️ Physical effort too early
▪️ Smoking or vaping
▪️ Certain medical conditions or medications

When bleeding is more than expected, the dental professional may:
▪️ Apply firm pressure with sterile gauze
▪️ Place local hemostatic agents (such as collagen or oxidized cellulose)
▪️ Use sutures (stitches) to stabilize the wound
▪️ Check for sharp bone edges or remaining tooth fragments
▪️ Review the patient’s medical history and medications
These measures are usually very effective in controlling bleeding.

▪️ Eat soft, cool foods
➤ What NOT to Do
▪️ Do not rinse, spit, or use straws in the first 24 hours

Seek professional help if:

📊 Comparative Table: Post-Extraction Care Recommendations
| Recommendation | Why It Helps | What to Avoid |
|---|---|---|
| Biting on gauze | Promotes clot formation | Removing gauze too early |
| Cold compress | Reduces bleeding and swelling | Applying heat in the first 24 hours |
| Rest and head elevation | Lowers blood pressure at the wound | Physical exertion |
| Soft diet | Prevents clot disruption | Hard, hot, or crunchy foods |
Post-extraction bleeding is usually manageable with simple and timely measures. Most complications occur when patients unintentionally disrupt the blood clot. Clear instructions and patient cooperation significantly reduce the risk of prolonged bleeding and delayed healing.
