After a Tooth Extraction: The First 24 Hours Decide the Rest

When a tooth comes out, a blood clot forms in the socket. That clot is the scaffold everything else builds on — it protects the exposed bone and nerve endings, and new tissue grows through it. Protecting it for the first 24 hours is essentially the whole of aftercare.

The first hour

Bite firmly on the gauze pad for a full 20 to 30 minutes without lifting it to check. Checking is the most common mistake; it disturbs the forming clot and restarts the bleeding. If it is still bleeding, replace with fresh gauze and bite for another 30 minutes. A damp black tea bag works well as a substitute — the tannins help the clot form.

Some oozing for several hours is normal, and a small amount of blood mixed with saliva looks far more dramatic than it is.

The first 24 hours: what not to do

• Do not rinse, spit or swill. Not even water. This is the single most important instruction.
• Do not use a straw. The suction can pull the clot straight out.
• Do not smoke. Smoking multiplies the risk of dry socket several times over, through both the suction and the chemistry.
• No alcohol, no hot drinks, no vigorous exercise.
• Do not poke the socket with your tongue or finger.

What to do instead

Rest with your head elevated. Use a cold pack on the outside of the cheek, 20 minutes on and 20 off, for the first day — that limits swelling, which usually peaks around day two or three. Take painkillers before the anaesthetic wears off rather than waiting for the pain to arrive; an anti-inflammatory such as ibuprofen generally works better than paracetamol here, if it is safe for you. Avoid aspirin, which thins the blood.

Eating

Soft, cool and non-spicy for the first day: dahi, khichdi, dal, mashed potato, banana, cold milk, ice cream. Chew on the other side. Avoid anything with small seeds or grains that can lodge in the socket, and avoid crisps, nuts and anything sharp for several days. Do not skip meals — healing needs fuel.

From day two

Start gentle warm salt-water rinses — half a teaspoon in a glass — after meals. Let the water fall out of your mouth rather than spitting. Resume brushing the other teeth normally, avoiding the socket itself for a few days. Most people are back to normal food within a week; a surgical or wisdom tooth extraction takes longer.

When to call us

• Bleeding that has not settled after two hours of firm pressure
• Pain that worsens from day three rather than improving — the signature of dry socket
• Swelling that increases after day three, or fever
• Numbness that persists beyond the day of surgery
• Difficulty swallowing or opening the mouth

Frequently asked questions

How long until I can eat normally after an extraction?

Soft food for the first 24 to 48 hours, then gradually back to normal over about a week. Surgical extractions and wisdom teeth take longer. Chew on the opposite side throughout.

Why can't I rinse my mouth after an extraction?

Rinsing, spitting and using a straw can dislodge the blood clot in the socket. Without that clot, bone and nerve endings are exposed and dry socket follows. Wait a full 24 hours, then rinse gently.

Can I smoke after a tooth extraction?

It is strongly advised against for at least 72 hours. Smoking substantially raises the risk of dry socket, through both the suction and the effect on healing. It is the single biggest risk factor.

Is swelling normal after an extraction?

Yes. Swelling typically peaks on day two or three and then settles. Swelling that starts increasing after day three, especially with fever, suggests infection and needs review.
