Developing a toothache while traveling can be stressful—especially when you are in another country, do not speak the local language fluently, and may be leaving Japan within only a few days.

The most important point is simple:

Do not try to determine the exact dental treatment you need based only on the symptom.

Tooth pain can have many different causes, and the appropriate treatment depends on an examination, diagnosis and your available time in Japan.

If you are visiting Tokyo and suddenly develop dental pain, you may still be able to receive an examination, diagnosis, pain management, temporary treatment or other appropriate dental care during your trip.

At PreBeau Oral Care in Akasaka, international patients can discuss their symptoms, diagnosis, treatment options, expected costs and travel schedule directly with the dentist in English.

For complete information about dental care for international residents and visitors, see our English-speaking dentist in Tokyo guide.

Quick Answer: What Should I Do If I Get a Toothache in Tokyo?

If you develop a toothache while visiting Tokyo:

1. Contact a dental clinic as soon as reasonably possible.
2. Explain where the pain is and when it started.
3. Tell the dentist whether you have swelling, fever, trauma or difficulty opening your mouth.
4. Tell the clinic when you are leaving Japan.
5. Do not assume that you need a particular procedure before you have been examined.
6. Bring information about previous dental treatment if available.
7. If you have travel insurance, check what documentation your insurer requires.
8. Seek emergency medical assistance rather than waiting for a routine dental appointment if you have potentially serious symptoms such as difficulty breathing or swallowing or rapidly spreading facial or neck swelling.

A dentist can then determine whether treatment can reasonably be completed during your stay or whether the immediate priority should be stabilizing the problem before you return home.

Why Can a Toothache Suddenly Appear While Traveling?

A toothache does not always mean the same thing.

Possible causes of dental pain can include:

• Dental decay
• Inflammation inside a tooth
• Infection around a tooth
• A cracked tooth
• A damaged or loose restoration
• Gum or periodontal inflammation
• Problems around a wisdom tooth
• Trauma
• Biting-related problems
• Other dental or non-dental conditions

Pain alone cannot reliably identify the cause.

For example, sensitivity to cold, pain when biting and spontaneous throbbing pain may suggest different possibilities, but these symptoms still need to be interpreted together with an examination and, when necessary, diagnostic imaging.

This is why telling a dentist:

“I think I need a root canal”

is generally less useful than describing what is actually happening.

A clearer description would be:

“I have pain in my upper right tooth when I bite. It started two days ago and became worse last night.”

Your symptoms help guide the examination, but the treatment decision should follow diagnosis.

Should I Wait Until I Return Home?

Sometimes travelers hope that a toothache will disappear on its own because they are returning home soon.

That may not always be a good idea.

Whether waiting is reasonable depends on factors such as:

• The suspected cause of the pain
• How severe the pain is
• Whether the symptoms are worsening
• Whether swelling is present
• Whether infection is suspected
• Whether the tooth has been injured
• How long you will remain in Japan
• How long your journey home will be
• Whether follow-up treatment is likely to be required

Even if definitive treatment cannot be completed during your trip, an examination may still be useful.

A dentist may be able to identify the likely problem, determine whether urgent treatment is necessary, discuss temporary stabilization when appropriate and explain what follow-up may be needed after you return home.

If you have only a short period remaining in Japan, see our guide to what dental treatments can realistically be completed during a short stay in Tokyo.

What Information Should I Tell the Dentist?

When requesting an appointment for tooth pain, describe the problem as specifically as possible.

Useful information includes:

• Where the pain is located
• When the pain started
• Whether the pain is constant or intermittent
• Whether the pain is getting worse
• Whether cold, heat or biting triggers the pain
• Whether there is swelling
• Whether you have noticed bleeding or discharge
• Whether the tooth has broken
• Whether a filling or crown has become loose
• Whether there was an accident or injury
• Whether the tooth has been treated previously
• Whether you have had root canal treatment on the tooth
• Whether you have fever or other symptoms
• Your medical conditions
• Your medications
• Your allergies
• The date you are leaving Japan

For tourists, your departure date is especially important.

A treatment plan that is realistic for someone living in Tokyo may not be appropriate for someone flying home in two days.

Can a Tourist See a Dentist in Tokyo?

Yes.

You do not need to be a Japanese resident simply to attend a private dental clinic.

International visitors can seek dental care in Tokyo even when they do not have Japanese National Health Insurance.

However, how payment works depends on the clinic and your circumstances.

PreBeau Oral Care is a fully private, self-pay dental clinic and does not accept Japanese National Health Insurance.

For a detailed explanation, see going to the dentist in Japan without Japanese health insurance.

If you do not have travel insurance either, you can still seek private dental care. Read Can I See a Dentist in Tokyo Without Travel Insurance? for a separate explanation of this issue.

Can My Toothache Be Treated in One Visit?

Sometimes—but not always.

The answer depends on the diagnosis.

Some urgent dental problems may be evaluated and managed during a single visit.

Other conditions may require:

• Dental X-rays
• Additional testing
• Multiple treatment sessions
• Medication when clinically indicated
• Definitive restorative treatment
• Root canal treatment
• Extraction
• Laboratory work
• Specialist treatment
• Follow-up after the initial appointment

For an international visitor, the goal is not necessarily to complete every possible procedure before leaving Japan.

The more realistic goal may be to:

diagnose the problem, control an urgent situation when possible, protect the tooth or surrounding tissues, and establish an appropriate next step.

If definitive treatment cannot safely or realistically be completed before departure, the dentist can explain what information should be communicated to your dentist at home.

What If I Am Flying Home Soon?

Tell the dentist your departure date before treatment planning begins.

This information can affect decisions about what is realistic.

For example, a dentist may need to consider:

• Whether the proposed treatment requires follow-up
• Whether symptoms may change after treatment
• Whether additional appointments are normally required
• Whether temporary treatment is more appropriate
• Whether treatment should instead be continued after you return home
• Whether you need records or imaging to take to your next dentist

Do not assume that the fastest procedure is automatically the safest or most appropriate procedure.

Travel schedule is one part of treatment planning—not a substitute for diagnosis.

What If the Toothache Is Caused by a Broken Tooth or Lost Filling?

A broken tooth, lost filling or loose restoration can also cause pain or sensitivity.

However, these problems have their own diagnostic and treatment considerations.

The remaining tooth structure, location and size of the fracture, previous dental treatment and condition of the dental pulp can all affect the treatment plan.

For that reason, a broken tooth should not automatically be treated as simply “a filling that needs to be replaced.”

This topic is covered separately in our guide:

Broken Tooth or Lost Filling While Traveling in Tokyo: What Should You Do?

When Is a Toothache More Urgent?

Dental pain should be assessed based on the overall situation rather than pain intensity alone.

Contact a dentist promptly if you have symptoms such as:

• Increasing dental pain
• Facial or gum swelling
• Pain that significantly interferes with sleeping or eating
• Difficulty opening your mouth
• A traumatic dental injury
• A broken tooth associated with significant pain
• Signs suggesting that an infection may be developing
• Symptoms that are becoming progressively worse

Some situations require more than a routine dental appointment.

If you develop difficulty breathing or swallowing, rapidly spreading swelling of the face or neck, major facial trauma, uncontrolled significant bleeding or another potentially life-threatening condition, seek appropriate emergency medical care.

In Japan, the emergency number for an ambulance is 119.

Can I Take Painkillers Until My Appointment?

Medication may temporarily reduce dental pain, but improvement in pain does not necessarily mean that the underlying dental problem has resolved.

Medication should also be used only when appropriate for your medical history, allergies, other medications and individual circumstances.

Do not use pain relief as a substitute for dental assessment when symptoms are significant, persistent or worsening.

Antibiotics are also not automatically appropriate for every toothache.

Whether medication is indicated should be determined based on the clinical situation.

What About Travel Insurance?

Travel insurance and dental treatment are separate from the clinical diagnosis.

Some insurance policies may provide limited benefits for unexpected or emergency dental treatment during an overseas trip.

Other policies may exclude dental care or apply specific conditions, limits or documentation requirements.

The dental clinic cannot guarantee that your insurer will reimburse treatment.

If you have travel insurance, contact your insurer and ask:

• Is emergency dental treatment covered?
• Is preauthorization required?
• Is there a maximum dental benefit?
• Do I need an itemized receipt?
• Do I need a dentist’s report or medical certificate?
• Does documentation need to be written in English?
• Do I pay first and submit a reimbursement claim later?

Dental Care for Tourists at PreBeau Oral Care

PreBeau Oral Care is a fully private dental clinic in Akasaka, Minato City, central Tokyo.

International patients can communicate directly with Dr. Kuniyasu Mori in English about:

• Dental pain and other urgent symptoms
• Examination findings
• Diagnosis
• Treatment options
• Clinical limitations
• Available time in Japan

• Referral when treatment outside our scope is required

Depending on the diagnosis, care for an urgent dental problem may involve examination, diagnostic assessment, management of symptoms, appropriate stabilization or referral.

We do not recommend a dental procedure simply because it can be completed quickly.

The treatment plan should reflect the diagnosis, the condition of the tooth and the patient’s available treatment window.

PreBeau Oral Care offers same-day emergency appointments when availability allows.

Emergency dental care starts from ¥33,000 including tax.

Additional charges may apply depending on the examination and care required, such as diagnostic imaging, medication, additional procedures, restorations, appliance-related treatment or insurance documentation.

Frequently Asked Questions

Can a tourist see a dentist for a toothache in Tokyo?

Yes. International visitors can seek dental care in Tokyo. At a private self-pay clinic, Japanese National Health Insurance is not necessarily required. The dentist will first need to examine the tooth and determine the cause of the pain before recommending treatment.

Can a toothache be treated during one dental appointment?

Sometimes. Certain urgent problems may be assessed or managed during one appointment, but other conditions require multiple visits or follow-up treatment. The answer depends on the diagnosis rather than the symptom alone.

Should I wait until I return home if I only have a few days left in Japan?

Not necessarily. If the pain is significant, worsening or associated with swelling or other concerning symptoms, obtaining a dental assessment before traveling may be appropriate. Even when definitive treatment cannot be completed, examination and stabilization may sometimes be useful.

What should I tell a dentist when requesting an urgent appointment?

Explain where the pain is, when it started, what triggers it, whether it is getting worse and whether you have swelling, fever, trauma or a broken restoration. International visitors should also tell the clinic when they are leaving Japan.

Can I send a photo of the painful tooth before my appointment?

Yes, a photograph may be useful for preliminary communication when a visible problem is present. However, a photograph alone usually cannot determine the cause of tooth pain and does not replace an examination or necessary diagnostic testing.

Can travel insurance cover a toothache in Japan?

Some travel insurance policies may cover unexpected or emergency dental treatment, but coverage varies considerably. Contact your insurer to confirm benefits, exclusions, authorization requirements and documentation requirements. A dental clinic cannot guarantee reimbursement.

Can I see a dentist in Tokyo without travel insurance?

Yes. Travel insurance is not required in order to attend a private self-pay dental clinic. You will generally need to pay the applicable dental fees yourself, regardless of whether you later submit an insurance claim.

Can a dentist prescribe antibiotics for a toothache?

Antibiotics are not automatically necessary for every toothache. Whether medication is indicated depends on the diagnosis and clinical findings. Dental treatment addressing the underlying cause may still be necessary.

When should I seek emergency medical care rather than wait for a dental appointment?

Potentially serious symptoms such as difficulty breathing or swallowing, rapidly spreading facial or neck swelling, major facial trauma or uncontrolled significant bleeding require urgent medical attention. In Japan, call 119 for an ambulance in a medical emergency.
