After a tooth extraction, the cotton or gauze should be kept in the operated area by biting gently for 30-60 minutes to favor the formation of the clot that protects the socket and allows healing. Removing it prematurely can cause additional bleeding or dissolve the clot, leading to a complication called dry socket.
Tooth extraction is one of the most frequent interventions in dentistry, but post-operative care is as important as the intervention itself. Many of the complications that occur after an extraction —prolonged bleeding, dry socket, infection— are due to not correctly following instructions during the first few days.
At Asensio Dental Clinic, Dr. Lucía Asensio Romero (Registration No. 46002287) provides each patient with a detailed post-operative protocol adapted to their case. The first visit is completely free.
When to remove the cotton after extraction
The general rule is to keep the gauze or cotton for 30-60 minutes after the extraction. During that time, the patient should bite it gently and constantly —do not chew or move the gauze— to exert continuous pressure on the socket. Pressure is the mechanism that stops bleeding and allows the fibrin clot to form that will seal the wound.
After 30-60 minutes, the gauze can be carefully removed. If there is active bleeding upon removal, a new clean gauze is placed and kept for another 30 minutes. If bleeding continues after 2-3 hours or is very heavy, the clinic must be contacted. A slight pinkish ooze mixed with saliva during the first few hours is completely normal and should not be interpreted as active bleeding.
The clot that forms in the socket is fragile during the first 24 hours. Everything that generates negative pressure in the mouth —sucking, drinking with a straw, smoking— can pull it out, causing dry socket, a painful complication that significantly delays healing. Therefore, smoking, drinking with a straw, or rinsing the mouth forcefully is strictly forbidden during the first 24 hours.
Post-tooth extraction care: complete guide
Care during the first 24-48 hours is the most important for a complication-free recovery. During the first 24 hours, you should not rinse your mouth, spit forcefully, smoke, drink alcohol, or consume hot drinks. Local cold —ice wrapped in a cloth applied in 20-minute cycles— reduces swelling and pain in the first few hours. The head should be kept elevated when resting to reduce pressure in the operated area.
Diet in the first 24-48 hours should be cold or lukewarm and of soft consistency: yogurt, smoothies, purée, ice cream. You must chew exclusively on the side opposite the extraction. From the second day, more solid foods can be introduced according to tolerance. Hard, crunchy, or very hot foods should be avoided until the gum has healed.
From the second day, you can start rinsing gently with lukewarm salt water —half a teaspoon in a glass— several times a day, especially after meals, to keep the area clean. Brushing can be resumed gently, avoiding the extraction area. Swelling reaches its peak between 48 and 72 hours and then progressively decreases.
| Period | Allowed | Forbidden |
|---|---|---|
| First 24h | Local cold, cold and soft foods, rest | Smoking, alcohol, straws, rinsing, heat |
| 24-72h | Gentle salt rinses, soft lukewarm foods | Smoking, alcohol, intense physical effort |
| First week | Progressively normal diet | Hard or crunchy foods in the area |

Frequently asked questions about dental post-operative care
What is dry socket and how is it prevented?
Dry socket (alveolitis) is the most frequent complication of tooth extraction: the clot that should form in the socket dissolves or detaches before the tissue has started to heal, leaving the bone exposed and producing intense pain that appears between the second and fourth day. It is prevented by not smoking, not using a straw, not rinsing forcefully in the first 24 hours, and following the post-operative protocol. If it appears, treatment consists of irrigating the socket and placing a medicated dressing that calms the pain within hours.
Is it normal to have swelling after an extraction?
Yes, especially in surgical extractions of impacted wisdom teeth. Swelling is the body’s normal inflammatory response to surgery. It reaches its peak between 48 and 72 hours and then progressively decreases. Local cold in the first 24 hours significantly reduces it. If swelling increases after the third day or is accompanied by fever, it may indicate infection and you should consult.
When can I go back to work or exercise?
For sedentary jobs, most patients return the next day. For physical work or intense exercise, it is recommended to wait at least 48-72 hours, as the increase in blood pressure can cause bleeding. In complex surgical extractions, the recommended rest can be 3-5 days.
