Dental Emergency? What to Do in the First 30 Minutes

In a dental emergency, what you do before you reach the office can decide whether a tooth is saved or lost. Here's your step-by-step guide for the most common situations.

Knocked-Out Tooth: The Clock Is Running

A knocked-out (avulsed) adult tooth can often be saved — but the odds fall sharply with every minute it spends dry. The reason: the root is covered in living cells (the periodontal ligament) that can reattach to bone if kept alive.

• Pick the tooth up by the crown — the white chewing part. Never touch or scrub the root. Those living cells are the whole ballgame.
• If dirty, rinse gently for a few seconds with milk or saline (water only if that's all you have — and briefly). No soap, no scrubbing, no wrapping in tissue — dry tissue kills the cells.
• Best option: place the tooth back in its socket right away, facing the right way, and hold it with gentle bite pressure on a cloth. It's not as scary as it sounds, and it's the tooth's best chance.
• Can't reinsert? Keep it in milk or tucked inside your cheek (adults only). Milk's temperature and chemistry keep root cells alive far longer than water or air.
• Get to us within 30–60 minutes. Replantation success is highest in that window.

Cracked, Chipped, or Broken Tooth

Rinse your mouth with warm water and save any fragments in milk or water — sometimes they can be bonded back. A minor chip isn't urgent (though sharp edges can be smoothed soon); a crack that causes pain on biting or lingering sensitivity to temperature may involve the nerve — call promptly. Meanwhile: chew on the other side, and skip very hot, cold, or hard foods.

Severe Toothache

• Floss gently around the tooth first — a surprising number of "emergencies" are a popcorn hull or seed lodged under the gum.
• Rinse with warm salt water and take an over-the-counter pain reliever as directed.
• Do not place aspirin against the gum — that folk remedy causes a chemical burn on soft tissue. Pain relievers work from the bloodstream, swallowed.

A toothache that wakes you at night, throbs, or lingers after hot or cold usually means the nerve is involved — it will not fix itself. Call us; the earlier we see it, the more options you have. (Curious why an infected tooth hurts so much? See our root canal article.)

Swelling or Abscess

Facial swelling means infection is spreading — this is the one dental problem that can become genuinely dangerous. A pimple-like bump on the gum, a bad taste, or a swollen jaw warrants a same-day call. Cold compresses (outside the cheek, 15 minutes on/off) help in the meantime. Never apply heat to a swollen face — it can draw the infection outward and worsen swelling.

Dentist or Emergency Room?

Go to the ER (or call 911) if: swelling is spreading toward the eye or down the neck, you have trouble breathing or swallowing, a high fever with facial swelling, or facial trauma with a possible jaw fracture. Hospitals handle the life-threatening part.

For everything else — knocked-out or broken teeth, toothaches, lost crowns, abscesses — call us first. ERs can prescribe antibiotics and painkillers, but they generally cannot treat the tooth itself; you'll still need the dental visit, just later and in more pain.
