After a tooth extraction, the empty socket must form a stable blood clot to begin healing. While following your dentist's instructions on medications and rest is crucial, there are also specific activities, foods, and habits you should avoid for the first few days to prevent complications such as dry socket, bleeding, or infection.
For at least two to three days following the procedure, refrain from brushing or flossing around the extraction area. Brushing too close can dislodge the forming blood clot, leading to bleeding, delayed healing, and increased pain. Instead, gently rinse with a salt-water solution to keep the site clean without disturbing the clot.
While ice packs can reduce swelling, applying heat directly over the extraction site is not recommended. Hot compresses may increase blood flow and cause the socket to bleed. Likewise, avoid vigorous rinsing or swishing for at least 48 hours, as this suction can dislodge the clot. When rinsing, use mild, lukewarm salt water and do so gently.
Alcohol can interfere with blood clot formation and interact with prescribed medications, so avoid it for at least 72 hours. Tobacco use—both smoking and vaping—creates suction that can pull the clot out (causing dry socket) and introduces chemicals that impair healing. Do not take aspirin for pain relief, as it thins the blood and can prolong bleeding; use ibuprofen or acetaminophen as directed by your dentist.
Stick to soft, cool foods—such as yogurt, smoothies, soups (warmed but not hot), mashed potatoes, and applesauce—until the anesthesia wears off and the extraction site begins to close. Hard, crunchy, or spicy foods can irritate the socket, dislodge the clot, and introduce debris into the wound. Also avoid hot liquids and foods that can burn the healing tissue.
Drinking through a straw creates a vacuum effect that can dislodge the blood clot (a condition known as dry socket). For at least one week, sip beverages directly from a cup. This prevents negative pressure in the socket and allows the clot to stabilize.
Tempting though it may be to touch the empty socket with your tongue or a toothpick, avoid doing so for at least the first week. Poking can disturb the clot, introduce bacteria, and increase the risk of infection. Let the area heal naturally, and refrain from inserting anything inside the socket.
