A tooth extraction is a procedure where a tooth is removed from its socket. The body immediately begins forming a blood clot within the empty socket. The primary purpose of using gauze is to apply continuous, direct pressure to the surgical site. This stabilizes the initial blood clot, controls bleeding, and is the first step in the healing process.
Proper Gauze Placement and Quantity
The effectiveness of gauze depends more on correct placement and pressure than on the number of pads used. The standard recommendation is to use one or two pieces of gauze, folded into a small, thick pad. This folding creates a dense material that delivers necessary force to the extraction site.
The gauze must be positioned directly over the tooth socket, not just in the general area of the mouth. The patient must bite down firmly and continuously on the pad for the recommended time. This constant pressure compresses the tissue, constricts small blood vessels, and allows the blood clot to solidify. Avoid loosely chewing on a large wad of gauze, as this fails to deliver focused pressure and hinders clotting.
Gauze Replacement Timing and Duration
The first application of gauze should remain undisturbed for 30 to 60 minutes to allow the initial clot to form. During this time, avoid talking, spitting, or sipping, as these actions can dislodge the newly forming clot. After this initial interval, the gauze is removed and inspected.
If the gauze is saturated with bright red blood, replace it with a fresh piece. Ensure the new gauze is slightly moistened before placement to prevent sticking. Continue replacement every 30 to 45 minutes until the bleeding visibly slows down. Once the gauze shows only light pink or faint red staining, indicating manageable oozing, its use can be discontinued.
Recognizing Normal vs. Excessive Bleeding
Some bleeding is expected for up to 24 hours following extraction, but distinguishing between normal oozing and active bleeding is important. Normal oozing mixes with saliva, creating a pink or reddish tint that can make the bleeding appear worse than it is. This light seepage indicates the body is forming a stable clot.
Active, excessive bleeding is characterized by bright red blood that quickly soaks the gauze pad, requiring a change every 15 to 20 minutes, or the feeling that your mouth is filling rapidly with blood. If persistent, heavy bleeding continues after two to three hours of constant, firm pressure with fresh gauze, try a secondary measure such as a moistened black tea bag. Black tea contains tannic acid, a natural astringent that helps constrict blood vessels and promote clotting.
If the bleeding remains heavy and uncontrollable, soaking a fresh gauze pad every 15 minutes after three to four hours of consistent pressure, seek professional help. Persistent, heavy bleeding that does not respond to sustained pressure or lasts longer than 24 hours warrants an immediate call to your oral surgeon or dentist.
