Emergency dentistry: what to do when dental disaster strikes

Dental emergencies arrive without warning — a sudden toothache, a knocked-out tooth, a crown that comes off the night before a wedding. They share one thing in common: they are never convenient.

Acting quickly and calmly genuinely changes the outcome, particularly with a knocked-out tooth where the window is measured in minutes rather than days.

First: is this a dental problem or a medical one?

Before anything else, rule out the situations where a dental appointment is the wrong destination. Call 000 or go to your nearest hospital emergency department if there is:

• Difficulty breathing or swallowing
• Facial swelling that is spreading, particularly towards the eye or down the neck
• Fever alongside dental pain or swelling
• Bleeding that will not stop after 20 minutes of firm pressure
• A facial injury involving possible fracture, or any loss of consciousness

Infection from a tooth can track into the spaces of the face and neck and compromise the airway. That is an emergency department presentation.

Then: stay calm and work the steps

1. Remain calm. Difficult in any emergency, but panic makes the next decisions worse. Take a few breaths.

2. Call us. (03) 9088 5808, Monday to Friday, 8:00am to 5:00pm. Tell reception exactly what has happened — it determines how quickly you are seen and what advice they give you on the phone.

3. Do the right first aid for the specific problem. This differs enormously between a knocked-out tooth and an abscess, and getting it wrong costs you. The detail is below and on our dental emergency page.

4. Get here safely. Drive carefully, or have someone drive you. Adding a car accident to a dental emergency helps nobody.

5. Follow the aftercare instructions. You will be given specific instructions for managing things at home. They are the difference between healing well and coming back.

How urgent is it, really?

The critical one: a knocked-out adult tooth

Time is the single biggest factor in whether the tooth survives.

• Pick it up by the crown — the chewing surface — never the root
• Do not scrub it, and do not remove tissue attached to the root
• If dirty, rinse briefly in milk or saliva. Never water — water damages the root surface cells that make reattachment possible
• If you can, put it straight back in the socket the right way round and bite gently on a clean cloth
• If you cannot, keep it moist in milk or saliva, or held inside the cheek — not for young children, because of the choking risk
• Get to a dentist immediately

A knocked-out baby tooth is not reimplanted — doing so can damage the adult tooth developing underneath. Still call us, but do not put it back.

Even a successfully reimplanted tooth needs splinting, follow-up, and usually root canal treatment later. Saving it on the day is the start, not the end.

First aid by problem

Severe toothache

Rinse with warm salt water. Clean gently between the teeth in case something is trapped. Take pain relief as directed on the packet. A cold compress on the outside of the cheek helps.

Do not put aspirin, oil of cloves or anything else directly on the gum — it burns the tissue and does not reach the nerve. Do not apply heat to a swollen face; it encourages infection to spread.

Pain that wakes you at night, or lingers after something hot, usually means the nerve is involved. That is a root canal or extraction conversation, not something that resolves on its own.

Swelling or an abscess

Call us the same day. Salt-water rinses, cold compress, pain relief, and keep an eye on whether the swelling is spreading. If it reaches the eye or the floor of the mouth, or you develop a fever or trouble swallowing, go to hospital.

Antibiotics alone do not cure a dental abscess. They may quieten it temporarily; the source — the tooth — still has to be treated.

Chipped or broken tooth

Keep any fragments in milk; sometimes a piece can be bonded back on. Rinse with warm water. Cover a sharp edge with sugar-free gum or dental wax so it does not cut your tongue. Avoid chewing on that side.

Cracked tooth

Often there is nothing to see, just a sharp pain on biting or on release. Avoid chewing on that side and book an appointment. Cracks do not heal, and they get worse.

Lost filling or crown

Keep the crown. Clean it gently. Temporary dental cement from a chemist can hold it for a few days — never use superglue, which is toxic to the pulp and makes proper recementing much harder or impossible.

If the tooth is sensitive, avoid extremes of temperature and chew elsewhere.

Something stuck between teeth

Floss gently. If it will not come out, leave it and call — do not go at it with a pin, a knife, or anything metal. More damage is done by the rescue attempt than by the popcorn husk.

Soft tissue injury — lip, tongue, cheek

Clean gently, apply firm pressure with clean gauze for 15 to 20 minutes, cold compress outside. Bleeding that has not stopped after 20 minutes of steady pressure needs an emergency department. Tongue and lip wounds bleed impressively and often look worse than they are.

Bleeding after an extraction

Roll clean gauze or a clean handkerchief into a firm pad, place it directly over the socket — not just between the teeth — and bite steadily for 30 minutes without checking. Sit upright. Avoid rinsing, spitting, hot drinks, alcohol and exercise. If it is still bleeding heavily after two rounds of this, call us.

Dry socket

A severe, throbbing ache starting three to four days after an extraction, often radiating to the ear, sometimes with a bad taste. It is not an infection; the clot has been lost. It responds well and quickly to a dressing — call us rather than enduring it.

Broken denture

Do not attempt to glue it. Household and repair-kit adhesives are toxic, distort the fit, and usually make a professional repair impossible. Bring the pieces — all of them.

Orthodontic wire or bracket

Cover a poking wire end with orthodontic wax or a small ball of sugar-free gum. A wire can be tucked down gently with the blunt end of a teaspoon. Do not cut a wire unless it is at the back of the mouth and a genuine choking risk. Contact the practitioner managing your treatment.

A blow to the jaw

If the teeth no longer meet properly, if the jaw will not open or close, or if there is numbness of the lip or chin, treat it as a possible fracture and go to an emergency department.

Managing pain until you are seen

• Pain relief taken as directed on the packet. Paracetamol and ibuprofen together, where both are suitable for you, are more effective than either alone for dental pain
• Ibuprofen is not suitable for everyone — asthma, stomach ulcers, kidney problems, some blood pressure and blood-thinning medications. Check with your pharmacist
• Cold, not heat, on the outside of the face
• Sleep propped up. Lying flat increases the throb, which is why toothache is worse at night
• Avoid extremes of temperature in food and drink, and chew on the other side
• Alcohol is not pain relief. It interacts with medication and makes bleeding worse

If you are taking pain relief around the clock to function, that is not a holding pattern — it is a reason to be seen.

What not to do

• Do not put aspirin against the gum
• Do not use superglue on a crown, a denture or a tooth
• Do not try to drain a swelling yourself
• Do not use someone else's leftover antibiotics
• Do not attempt to extract a tooth, however loose
• Do not apply heat to facial swelling
• Do not ignore a swelling that is going down — an abscess that stops hurting has often burst, and the infection is still there

Children

Children's emergencies are usually knocks to the front teeth. The principles: a baby tooth is never put back; a displaced or discoloured baby tooth still needs checking, because the adult tooth is developing right behind it; and a tooth that darkens weeks after a knock is common and should be reviewed rather than panicked over.

Keep a child calm, use cold on the outside of the lip, and call. See family and children's dentistry.

After hours

We do not operate an on-call service. Between 5:00pm and 8:00am, and at weekends and public holidays:

• Life-threatening — 000, or your nearest emergency department
• Urgent, not life-threatening — Nurse-on-Call, 1300 60 60 24, 24 hours, staffed by registered nurses
• Public emergency dental care — the Royal Dental Hospital of Melbourne, 720 Swanston Street, Carlton, for eligible patients
• Can wait until morning — manage the pain and call us when we open. Online booking is available overnight.

If it happens away from home

Interstate or overseas, find a registered local practitioner rather than improvising. Travel insurance usually covers emergency dental treatment for pain relief but rarely covers definitive or elective work, and it almost never covers treatment you travelled specifically to have. Keep receipts and any radiographs.

Before a long trip, a check-up is worth more than the kit you pack — most travel emergencies are problems that were already visible.

Why choose Victorian Dental Group

Experienced with urgent problems. Our practitioners handle a range of emergency presentations every week — abscesses, fractures, knocked-out teeth, severe toothache, lost restorations.

We keep capacity for urgent cases. Call and tell us what has happened rather than booking online, so we can prioritise appropriately.

Transparent about cost. We are not interested in taking advantage of anyone at their most vulnerable. You will be told what the treatment costs before it starts, and often the first appointment is about relieving pain and stabilising things, with definitive treatment planned afterwards.

On-site imaging, including OPG, so we can diagnose during the appointment rather than sending you elsewhere.

We are a general dental practice and hold no specialist registration. Where an emergency needs specialist care — a complex facial injury, surgery under general anaesthetic — we will say so and arrange it.

Questions we are asked

Will I be seen the same day? For genuine urgency we do our best, and calling rather than booking online is what makes that possible.

Do I need to be an existing patient? No.

Will you just take the tooth out? Not unless that is genuinely the best option. The first visit is usually about getting you out of pain and working out what is going on, and you decide what happens next with the costs in front of you.

Can I get antibiotics over the phone? No. A tooth cannot be diagnosed down a phone line, and antibiotics without treating the cause simply delay things.

Should I go to my GP or a hospital instead? For airway, swelling and fever, yes. For a tooth problem, a GP can usually only offer pain relief — the treatment is dental.
