Flying after tooth extraction, root canal treatment and implants: how long to wait, and what about diving?

Can you fly after having a tooth removed?

After a simple extraction, flying is usually possible after 24 to 48 hours, and after surgical removal, such as a wisdom tooth, after 72 hours. Felkai et al. propose these minimum intervals in the British Dental Journal (2023), provided the site is not painful, swollen or bleeding; however, they recommend waiting a week after most procedures.

The authors stress that these are starting points rather than firm guidelines: research is limited, mainly concerns military aircrew, and no recommendations had previously been published for patients flying after dental treatment. The dentist determines the final timing after assessing the procedure, healing and nature of the flight.

Passenger aircraft cabins are pressurised, but cabin pressure corresponds to an altitude of up to 8 000 feet, around 2 400 m, and changes during take-off and landing. Felkai et al. also highlight a rare complication, subcutaneous emphysema, where air enters beneath the skin when a fresh socket is exposed to pressure changes in flight or underwater; the article on care after extraction explains the first day’s precautions.

What is barodontalgia, and why do teeth hurt on a plane?

Barodontalgia is tooth pain caused by a change in ambient pressure, on a plane or while diving. It usually signals an existing problem rather than a new disease: in Zadik’s review (2010), the most frequent causes of in-flight tooth pain were leaking fillings and decay without pulp involvement (29.2%), dead pulp or inflammation around the root tip (27.8%), disease of vital pulp (13.9%), recent treatment (11.1%) and pressure-related sinus inflammation (9.7%).

A systematic review by Nakdimon and Zadik (2019), covering 4 894 aircrew members and divers, found barodontalgia in 8.2% overall: 9.8% of divers and 5.8% of aircrew. Crews in pressurised aircraft reported it more often than those in unpressurised aircraft (7.3% versus 3.2%), so cabin pressurisation does not prevent this pain.

Pressure changes can also damage a tooth or filling itself, known as dental barotrauma. A 2026 review in Dental Traumatology describes how air trapped beneath a leaking filling, in an inadequately filled canal or beneath a poorly fitting prosthesis changes volume with pressure, potentially causing a tooth to crack or a filling to come out.

Flying after a filling or root canal treatment, and with a temporary filling

After a filling, Felkai et al. recommend postponing flights for at least 24 hours, ideally a week. The data they cite suggest that nearly one third of in-flight tooth pain cases involve teeth treated within the previous week, although such pain does not worsen the long-term treatment outcome.

According to the same authors, the earliest flight after root canal treatment is after 72 hours. When treatment spans several visits, sealing the tooth properly matters: a damaged dressing and open canals can rarely contribute to subcutaneous emphysema, so the authors recommend a dressing made of two layers of material.

If you are flying between appointments, tell your dentist before the dressing is placed. The article on temporary fillings explains what to do if the dressing comes out while travelling or the tooth starts to hurt.

Flying after dental implants and a sinus lift

After uncomplicated implant placement, Felkai et al. give 72 hours as the earliest time to fly. After more complex procedures, such as a maxillary sinus floor elevation (sinus lift) or bone graft, the minimum is 2 weeks; the recommended interval after a sinus lift is 6 weeks.

After a sinus lift, pressure changes during flight can cause traumatic sinusitis, which the authors say may lead to failure of the procedure. Treatment therefore involves planning a return journey by land or a sufficiently delayed flight; the article on sinus lifts and bone grafts describes the procedure itself.

Similar care applies after closure of an oroantral communication, which sometimes develops during upper back tooth extraction. The British Association of Oral Surgeons (BAOS) advises no nose-blowing, sneezing with the nose pinched shut, drinking through straws, playing wind instruments or diving; the surgeon decides when flying is possible.

How long should you wait before flying and diving? Overview

The table compares the shortest intervals proposed by Felkai et al. (2023) with Divers Alert Network (DAN) advice for divers. All timings apply only if the site is not painful, swollen or bleeding and the dentist has not advised otherwise.

Diving after tooth extraction: how long should you wait?

Diving after extraction requires a longer break than flying. Divers Alert Network (DAN), an organisation concerned with diver safety, states that most specialists recommend at least 4 weeks after uncomplicated wisdom tooth removal. Deeply impacted teeth may take months to heal; do not dive immediately after extraction, even if it was uncomplicated.

DAN also highlights the regulator mouthpiece: a numb or sore jaw may not hold it securely, and a loosely held regulator creates a risk of drowning. Before diving, make sure you can hold the mouthpiece without pain for the entire planned duration, and do not dive while still taking painkillers after treatment.

Divers experience barodontalgia more often than aircrew. In a study of 1 317 French military divers, 7.3% had tooth pain while diving, more often in upper teeth (62.2%) and during descent (77.3%). Among those having dental check-ups less than once a year, the rate was 14.5%, compared with 6.3% in those checked at least annually (Gunepin et al., 2016).

The 2026 review in Dental Traumatology stresses that no international dental society has yet issued guidelines for divers, so it is always worth agreeing a return date with the dentist who performed the procedure.

How can you plan travel after dental treatment?

Allowing time between completing treatment and departure is the easiest way to reduce the risk of tooth pain while travelling. The list brings together practical advice from the cited sources; the article on travelling for dental treatment explains planning treatment during a visit to Poland.

• Have a dental check-up a few weeks before a longer journey or diving trip, allowing time to treat any tooth already causing symptoms.
• Give your dentist your flight dates before scheduling an extraction, implant or root canal treatment.
• Do not schedule dental surgery for the day before a flight; expect several weeks without flying after a sinus lift.
• If you fly with a cold or blocked nose, remember that upper back tooth pain on landing may come from a sinus.
• Tooth pain that persists after landing usually has a dental or sinus cause and needs a dental appointment.
• Increasing swelling of the face or neck, difficulty breathing or swallowing require urgent help: go to a hospital emergency department (SOR) or call the emergency number 112.

How it works at DentalBlue

At DentalBlue, the clinic’s own radiology unit takes sinus X-rays, panoramic X-rays, CBCT scans and intraoral images, and implants are planned using tomography. Surgery, including tooth removal, is performed under local or general anaesthesia. If you plan to fly or dive, give your travel dates when arranging the appointment so the dentist can take them into account in your treatment plan. The clinic in Białystok sees patients Monday to Friday from 8:00 to 20:00 and Saturdays from 8:00 to 16:00.
