Flying with Tooth Pain: What to Know Before Your Trip

A vacation or business trip is rarely the best time for a toothache. But I often get calls from patients asking if it is safe to fly with tooth pain. The short answer is yes, it is generally safe, but it may not be comfortable. Traveling by air involves pressure changes that can turn a mild ache into a sharp, throbbing pain, which is definitely not something you want to deal with when you should be enjoying your journey.

At Evergreen Endodontics, we frequently assist patients from Issaquah, Bellevue, SeaTac, and the greater Seattle area who want to travel without worrying about their teeth. If you have time before your flight, it is worthwhile to have the tooth checked. It is understandable if you are already in pain or on a tight schedule before your trip. Fortunately, there are a few things you can do to manage a toothache until you get home.

Why flying makes tooth pain worse

Air pressure dramatically drops as the plane climbs to higher altitudes. These pressure changes affect the air inside your body, including tiny pockets of air in your teeth and sinuses. When a tooth has a crack, a deep cavity, an infection, or a failing root canal, any trapped air or fluid can expand and put pressure on the nerve. This can result in a sudden, sharp pain that may feel worse than it did on the ground. Dentists call this barodontalgia - tooth pain triggered by altitude pressure changes. It is not just uncomfortable - it can be distressing. Understanding how pressure changes can impact oral pain helps to prepare for the flight.

Upper back teeth are especially prone to discomfort because of their proximity to the sinus floor. Sinus pressure during takeoff and landing can mimic tooth pain, even when the teeth themselves are healthy. If you already have sinus congestion, whether from allergies or a cold, the effect may be intensified and more uncomfortable. This understanding can sometimes help in recognizing the source of the pain and how best to address it while flying.

What to do before you fly

• Schedule a dental exam if you have any sensitivity or lingering pain. It is better to confirm any issues before travel.
• Avoid chewing hard foods on the affected side both before and during travel. It minimizes the risk of worsening any underlying problem.
• Take any prescribed pain medication as directed by your dentist. Proper dosage can manage discomfort effectively.
• Use a decongestant if sinus pressure is a known trigger for you. It can reduce sinus-related discomfort.
• Pack a small dental kit with floss, an over-the-counter pain reliever, and our office number. Being prepared can make you feel more secure while traveling.

Taking these preventive steps can make a noticeable difference in your comfort levels during the flight. Thinking ahead allows you to focus on the more enjoyable aspects of your travel.

If tooth pain starts during the flight

If you feel a sharp pain during takeoff or landing, there are small steps you can take to relieve it. Try swallowing, yawning, or chewing gum to help equalize the pressure inside your ear and sinus cavities. Avoid very hot or very cold drinks since these can trigger sensitivity in your teeth. An over-the-counter pain reliever can also help if you have confirmed with your healthcare provider that it is safe for you to take. If these measures do not bring relief after landing, contact a dentist or endodontist to assess the situation more thoroughly.

In rare cases, if you experience severe symptoms like swelling, fever, or trouble swallowing, it may indicate a serious infection requiring immediate attention. Seek emergency care promptly rather than waiting until you get home. Prioritizing your health is essential.

Flying after a root canal

A root canal is not a reason to cancel a flight. Once the numbing wears off and the tooth is settled - usually within a few days - cabin pressure should not bother the treated tooth. What matters is what the tooth has covering it. In the first day or two after treatment, the tissue around the root can still be tender, so expect mild pressure sensitivity on the plane. After that, the main concern is the temporary filling: it seals the access hole but is not as strong as a final restoration, so avoid chewing hard foods on that side during your trip. If you had a root canal within the last 48 hours, ask us before you fly. And if the tooth was treated months or years ago and starts hurting at altitude, that can signal a failing root canal that needs evaluation - here is what happens after a root canal: core build-up and crown, including why the timing of the final crown matters.
