Rest comfortably with your head slightly raised

An extra pillow may help with swelling after an extraction. After sedation, resting with your head elevated on pillows or in a recliner is also recommended.[1][2]

Raise your head without stacking pillows so high that your neck becomes uncomfortable. Support your head and upper body comfortably. The adjustable bed shown above is just one example, not something you need to buy. An ordinary bed and pillows can also help you adjust your position.

Is there a set angle or number of nights?

The hospital instructions cited here recommend raising the head, but do not set one angle or duration for everyone. You do not need to copy the angle in the image. Follow your dental team's advice for the first night and the days that follow.[1][2]

Swelling and discomfort may last longer after more extensive surgery. If pain is severe or bleeding continues despite changing position, contact your dentist rather than simply adjusting your pillows and waiting.[6]

Do not fall asleep with gauze in your mouth

Biting on gauze applies pressure to help stop bleeding. It is not meant to stay in all night. Boston University Henry M. Goldman School of Dental Medicine advises patients not to sleep with gauze in their mouth.[3]

The University of Illinois Chicago College of Dentistry also advises removing gauze for sleep and stopping its use once bleeding has stopped. If you are still bleeding, however, do not simply remove it and go to sleep. Follow your dental team's instructions to control the bleeding first.[4]

Blood-tinged saliva is different from ongoing bleeding

A small amount of blood mixed with saliva can look like more bleeding than it is. It may also lightly stain your pillow; placing a clean towel over it can help.[4]

But if fresh red blood keeps flowing, do not lie down and wait. Sit up, place clean gauze over the extraction site, and bite firmly for the time your dental team advised. Contact the dental practice if pressure does not stop the bleeding.[1][6]

Have someone stay with you after IV sedation

Aftercare differs depending on whether you had local anaesthetic alone or a sedative through a vein. IV sedation can continue to affect your judgement or balance after treatment.

A responsible adult should care for you for 24 hours after IV sedation. Rest that day, avoid driving and alcohol, and take medicines as directed. Do not assume you can travel home or spend the night alone just because the extraction site seems fine.[5]

When to get help instead of going to sleep

Contact Gangbuk Baeksang Dental Clinic if pressure does not stop the bleeding or prescribed pain medicine does not control the pain. In particular, difficulty breathing or swallowing, or rapidly increasing swelling, needs immediate emergency care. Do not wait for a change of position or sleep to make these symptoms improve.[3]

During the first 24 hours, do not touch the socket with your tongue or fingers or rinse vigorously. Even if your mouth feels unpleasant before bed, avoid disturbing the wound.[6]
