The short answer

For the first twenty-four hours, the job is simple: protect the clot. Bite on gauze for an hour, ice the cheek, keep painkillers ahead of the soreness, and do not rinse, spit, smoke, or use a straw.

Most people feel noticeably better by day three. What follows is what each day usually looks like, and the specific signs that mean picking up the phone instead of waiting.

The first hour

Bite down on the gauze and leave it alone. Checking it every few minutes disturbs the clot that the pressure is there to form. If bleeding is still bright after an hour, put fresh gauze in and give it another hour.

Do not drive yourself into a busy afternoon. Go home, sit up, and stay quiet.

Day one

Numbness fades over two to four hours. Take a painkiller before it does. Ibuprofen suits dental pain well if you are able to take it, and following the dose on the packet is more effective than waiting for pain to demand it.

Ice against the cheek in twenty-minute stretches, with twenty minutes off between them. It only helps while swelling is still forming, which is roughly the first day.

Eat soft and cool once the numbness has gone, so you do not bite your cheek without feeling it. No straws, no smoking, no vigorous rinsing, no spitting. Sleep with an extra pillow.

Day two and three

Swelling usually peaks now rather than on day one, which surprises people who assume the worst is behind them. Bruising on the cheek or jaw can appear and is not a problem.

Start gentle salt-water rinses after meals. Half a teaspoon of salt in a cup of warm water, held in the mouth and allowed to fall out rather than spat.

Soreness should be steadily easing by the end of day three. That direction of travel matters more than the level of pain on any given day.

Day four to seven

Most people are back to ordinary food, carefully, and off painkillers or nearly so. Dissolvable stitches loosen and disappear during this stretch, and swallowing one is harmless.

The socket looks alarming around now. A whitish, jelly-like layer over the site is granulation tissue, which is healing rather than infection. Food will lodge in the socket, and the rinses will move it. Do not poke at it with anything.

Week two onwards

The gum closes over the socket during the second and third weeks. Bone fills in underneath over the following months, and you will not feel that happening.

If you are planning to replace the tooth, this is the stretch where that conversation gets scheduled.

When to call

Call your dentist now if pain gets worse after day three instead of better, especially alongside a foul taste and a deep ache running toward your ear. That combination is usually dry socket, and it is treated in a short visit. Call if bleeding stays bright after two hours of firm pressure, if swelling is still growing after day three, if you cannot open your mouth normally, or if numbness in your lip or chin is still there the next day.

If a tooth on the other side has started causing trouble in the meantime, that is a separate problem and an urgent one.

Go to an emergency room tonight if swelling reaches your eye or your neck, if a fever comes with it, or if swallowing or breathing becomes difficult. Those are signs of an infection spreading beyond the tooth, and that is a medical emergency before it is a dental one.
