Almost everyone who has dental work in Phuket flies home afterwards, often within a few days. The good news is that most treatments do not care about aeroplanes at all. The exceptions are worth knowing about, because they are the ones where waiting one more day is much cheaper than the alternative.
Why altitude matters at all
Cabins are pressurised, but not to sea level — a typical cruising cabin sits somewhere around the pressure you would feel at 1,800 to 2,400 metres of altitude. Gas trapped in a sealed space expands as the pressure outside it drops.
In a healthy, properly restored tooth there is no trapped gas, so nothing happens. In a tooth with an air pocket under a temporary filling, an untreated infection, or a socket that has only just started to clot, there is something for that pressure change to act on. Dentists call the resulting pain barodontalgia. It is uncommon, it is not dangerous in itself, and it is almost entirely avoidable by timing.
The second issue has nothing to do with pressure: you will be a long way from your dentist. If a clot fails or a swelling develops on day two, you want to be somewhere a dentist can see you the same afternoon.
Rough waiting times
These are general guides, not instructions for your case. The dentist who did the work is the one who knows how the tooth behaved and should always have the final word.
| Treatment | Usual wait before flying |
|---|---|
| Cleaning, whitening | None |
| Composite filling | None, once the anaesthetic wears off |
| Root canal, fully sealed | 24 hours |
| Root canal left open or on a temporary dressing | Ask before you book the flight |
| Simple extraction | 24–48 hours |
| Surgical extraction, wisdom tooth | 48–72 hours, sometimes longer |
| Implant placement | 48–72 hours in a straightforward case |
| Sinus lift or upper bone graft | Often 1–2 weeks — this one genuinely matters |
| Crown or veneer fitted | None |
The one to take seriously: sinus work
A bone graft or sinus lift in the upper jaw sits directly against an air-filled cavity. That is exactly the situation where pressure change can do harm, and it is the case where a surgeon may ask you to wait considerably longer than you expect. If you are having upper implant work and flying soon after, raise it at the planning appointment, not on the day.
Practical things that help on the flight
- Take the painkillers you were prescribed before boarding, not after the pain starts.
- Drink water and skip the alcohol. Alcohol thins the blood, dries you out and disagrees with most post-operative medication.
- Avoid a straw for the first few days after an extraction. Suction is what dislodges a clot; a dry socket on day three of a long-haul flight is a miserable way to travel.
- Chew on the other side. Obvious, and still the most commonly forgotten instruction.
- Carry the clinic's number and your treatment note. If you do need a dentist at home, the first thing they will ask is what was done.
If something starts hurting mid-flight
It is nearly always pressure on an air pocket or an inflamed nerve, and it nearly always eases during descent. Painkillers, warmth on the cheek, and staying hydrated is the extent of what can be done at 11,000 metres. Get it looked at when you land — and message us, because we would rather know.
How long after a tooth extraction can I fly?
For a straightforward extraction, most dentists suggest 24 to 48 hours. Surgical extractions and wisdom teeth usually need longer. Ask the dentist who did it.
Can I fly the same day as a filling?
Yes. A finished composite filling seals the tooth completely and cabin pressure has nothing to act on. Just wait for the anaesthetic to wear off before eating.
Is flying after implant surgery safe?
In a straightforward lower-jaw case, most people fly after two to three days without any trouble. Upper-jaw work involving the sinus is the exception and can need one to two weeks.
What about a temporary crown — will it come off on the plane?
Not from the pressure. Temporary crowns come off because of sticky food. Avoid chewing gum and toffee until the permanent one is fitted.
I have a flight tomorrow and my tooth hurts. Should I still come in?
Yes. Making a painful tooth safe to fly with is usually quick, and it is far better done here than discovered at 35,000 feet.
