It is normal to have swelling in the face after oral surgery. It reaches its apex between 24 and 72 hours and reduces on the 4th day following the procedure.
Swelling may be diminished with the immediate application of cold. Make a compress by putting ice cubes or a bag of frozen peas in a wet towel. Apply on the area for 15 minutes, then remove for 15 minutes. Repeat a few times.
Swelling can also occur after a dental trauma or when there is a serious infection (a tooth abscess). In these situations, you can apply the same procedure described above but you must see a dentist urgently.
