…When to see an emergency dentist
Common dental emergencies: what to do first, and how soon to be seen
A quick first-aid guide. If you’re not sure how urgent it is, call the clinic and ask.
Same day, as soon as possible
Knocked-out tooth
Hold it by the crown (the white part), never the root. If it’s dirty, rinse it for a few seconds in milk or saline. Try to push it gently back into the socket and bite on gauze to hold it; if you can’t, keep it in milk and bring it with you. The sooner you’re seen, the better the chance of saving it, ideally within an hour. Don’t put a baby tooth back in, but still come in promptly.

Call the same day
Severe or persistent toothache
Rinse with warm salt water and take over-the-counter pain relief as directed. Don’t hold a tablet against the gum. Pain that lasts, wakes you at night or lingers after hot or cold may mean the nerve is inflamed, and some cases need root canal treatment.
Learn about Root canal treatment
Same day
Gum or facial swelling
Swelling can mean infection or an abscess, and it’s common around an inflamed wisdom tooth. Use a cold compress on the outside of the cheek; don’t apply heat or try to burst it. If it spreads quickly, reaches the eye or neck, or comes with fever or trouble breathing or swallowing, go to A&E.
Learn about Tooth removal
Book promptly (same day if painful or bleeding)
Broken or chipped tooth
Keep any pieces, rinse with warm water, use a cold compress for swelling and avoid chewing on that side. Small chips can usually be repaired with a filling; deeper breaks or large losses may need a crown.
Learn about Fillings, Crowns & bridges
Seek help if it won’t stop
Bleeding after an injury
Press clean gauze firmly on the area for 10 to 15 minutes. A little oozing after an extraction is normal; heavy bleeding that continues under pressure needs help straight away.
Book promptly
Lost filling or crown
Keep the crown safe, chew on the other side and don’t glue it back yourself. An unprotected tooth breaks and becomes sensitive more easily, so get it seen soon.

Dental trauma first aid
Knocked-out or chipped tooth: what to do first
Adult teeth and children’s baby teeth are handled differently. The key difference: put an adult tooth back in as soon as possible, but never put a baby tooth back.
Adult tooth: act within the first hour
1. Stop the bleeding and swellingIf the mouth is bleeding, rinse with water, then hold a cold compress against the area.
2. Call the dentistComfort the injured person and check for any other injuries that need attention right away.
3. Find the toothIf a tooth is chipped or knocked out, find the pieces or the whole tooth. If you can’t find it, a chest X-ray may be needed to make sure it wasn’t inhaled.
4. Hold the crown, not the rootTouch only the chewing part (green circle), never the root (red circle); the cells on the root surface decide whether the tooth can be saved. If it’s dirty, rinse it gently in water or saline for a few seconds. Don’t scrub or wipe it.
5. Put it back in the socketPlace the tooth back facing the right way and bite gently on clean gauze or cloth to hold it.
6. Can’t put it back?Keep the tooth in milk, or inside the injured person’s cheek to keep it moist. Don’t soak it in tap water or wrap it in tissue.
7. See a dentist straight awayThe sooner the better: aim to be seen within an hour, ideally within 30 minutes.
Baby tooth
- 1. Stop the bleeding and swelling
Rinse with water, then use a cold compress.
- 2. Call the dentist
Comfort your child and check for other injuries.
- 3. Find the tooth
Find the pieces or the whole tooth. If you can’t find it, a chest X-ray may be needed.
Don’t put a baby tooth back in the socket.
- 4. See a dentist soon
Bring your child in as soon as possible so the dentist can check the adult tooth developing underneath.

What an emergency visit costs
An emergency visit usually starts with an examination, with X-rays if needed, before any treatment is agreed. As a guide, the Prince Philip Dental Hospital private patient fee schedule puts an examination or consultation at around HK$600–2,500 in Hong Kong. Fillings, root canal treatment or extractions are charged separately and depend on what you need.
These figures are for reference only and are not our clinics’ actual fees. Your dentist will explain the cost after examining you.

Frequently asked questions
Is there a 24-hour emergency dentist in Hong Kong?
None of our five clinics is open 24 hours. On weekdays we open from 9:00 or 9:30am until 6:00 or 6:30pm; all five are open on Saturday mornings; Smith & Jain Dentists (Central) and Bayside Dental Tung Chung are also open on Sunday mornings; all close on public holidays. Outside these hours, call 999 or go to A&E for anything life-threatening, and contact your nearest clinic as soon as it opens for everything else.
Are any dentists open on Sunday?
Yes. Smith & Jain Dentists in Central is open 09:00–13:00 on Sundays, and Bayside Dental Tung Chung 09:00–13:00. Our other three clinics are closed on Sundays, and all five close on public holidays. Sunday dentist in Central: Smith & Jain Dentists →
What should I do about a toothache on a public holiday?
Our clinics are closed on public holidays. Rinse with warm salt water, use a cold compress on the outside of the cheek, take over-the-counter pain relief as directed, and call your nearest clinic when it next opens. If swelling spreads fast, bleeding won’t stop, or you have trouble breathing or swallowing, call 999 or go to A&E.
Can I get a same-day appointment?
Each clinic keeps time for emergencies every day and aims to see you the same day where availability allows. The earlier in the day you call, the better your chances of a same-day slot.
Can a dentist pull a tooth the same day?
Sometimes. If the dentist examines you, takes an X-ray and finds the tooth can’t be saved, it can be removed at the same visit. If there’s significant swelling or infection, the dentist may treat that first and remove the tooth at a later appointment. Wisdom teeth that need surgical removal are usually booked separately. Tooth removal →
What should I do if a tooth is knocked out?
Pick it up by the crown (the white part), not the root. If it’s dirty, rinse it briefly in milk or saline. Try to place it back in the socket; otherwise keep it in milk and bring it with you. The sooner you’re seen, the better. Don’t put a baby tooth back in.
How can I ease the pain before I arrive?
Rinse with warm salt water, use a cold compress on the outside of the cheek, and take over-the-counter pain relief following the packet instructions. Don’t place a tablet directly on the gum.
Is facial swelling urgent?
Swelling can signal infection and should be checked the same day. If it spreads quickly, affects your eye, or you have trouble breathing or swallowing, treat it as a medical emergency: call 999 or go to the nearest A&E.
Should I go to A&E or see a dentist?
For most dental problems, such as pain, broken teeth or a lost crown, a dentist is the right place. For anything life-threatening, bleeding that won’t stop, or trouble breathing or swallowing, call 999 or go to A&E.
Do you treat children’s dental emergencies?
Yes. Tell us your child’s age and what happened when you call, so we can give the right first-aid advice and find a suitable slot. Kids dentistry →
How much does an emergency dental visit cost?

As a guide, the Prince Philip Dental Hospital private patient fee schedule puts an examination or consultation at around HK$600–2,500 in Hong Kong, with any treatment charged separately.
