Toothache in Japan – Guide for Tourists

A sudden toothache during travel is painful, distracting, and surprisingly common. This guide explains the most likely causes, first-aid steps you can take from your hotel room, how to find an English-speaking dentist in Japan, and what to expect at a Japanese dental clinic visit.

Common Causes of Toothache While Traveling

Travel often brings out dental problems that have been quietly building for months. Cabin pressure changes on long flights, irregular eating, hard or sticky foods, and disrupted oral hygiene can all trigger a flare-up.

Cavities (mushiba). The most common cause. Pain is usually worse with cold, hot, or sweet foods. A small cavity may be manageable for a few days with over-the-counter pain relief; a deep cavity reaching the nerve typically needs prompt dental care.
Lost or loose filling or crown. Older fillings can dislodge while eating mochi, sticky candy, or crusty bread. The exposed tooth is sensitive to air and temperature. A pharmacy temporary filling kit can buy you a few days, but a dentist visit is usually needed.
Wisdom tooth pain (oyashirazu). Especially in travelers in their late teens through thirties. Pain is felt at the very back of the jaw, sometimes with swelling, and often worse when chewing. May indicate impaction, infection, or simply inflammation of the surrounding gum.
Gum inflammation (shinikuen). Red, swollen, or bleeding gums — sometimes with a bad taste in the mouth. Often triggered by skipped flossing, stress, or a change in diet during travel.
Tooth abscess. A pocket of infection at the root of a tooth, usually following an untreated cavity. Symptoms include throbbing pain, swelling, fever, and a bad taste. This is a more urgent condition and should be seen by a dentist the same day if possible.
Sinus-related tooth pain. Sinus infections during cold and flu season can cause aching in the upper back teeth. The teeth themselves may be healthy — treating the sinus issue resolves the pain.
Cracked tooth or grinding. Sharp pain when biting may indicate a cracked tooth. Long flights and travel stress also worsen night-time grinding (bruxism), which can cause sore jaw muscles and tooth sensitivity.

First Aid for Toothache

For a mild toothache without obvious swelling or fever, the following steps can usually keep you comfortable until you see a dentist.

Take an over-the-counter pain reliever. Acetaminophen (paracetamol) or ibuprofen, both available at any Japanese pharmacy. Ibuprofen is often more effective for dental pain because it reduces inflammation as well as pain. Follow the dose printed on the package.
Rinse with warm salt water. Dissolve about half a teaspoon of salt in a cup of warm water and rinse gently for 30 seconds, then spit. Repeat several times a day. This reduces minor inflammation and helps clean the area.
Apply a cold compress to the cheek. A cloth-wrapped cold pack against the outside of the cheek for 15–20 minutes at a time can numb the area and reduce swelling. Do not apply ice directly to the skin.
Avoid extreme temperatures and hard foods. Skip very hot, very cold, very sweet, or hard foods until you see a dentist. Eat softer items on the opposite side of the mouth.
Keep the area clean. Brush gently around the painful tooth and floss carefully. If a piece of food appears lodged, gentle flossing usually removes it — do not pick with sharp objects.

What to Avoid

Do not place aspirin directly on the gum. A common myth — this can cause a chemical burn of the gum tissue. Take pain relievers as pills instead.
Do not apply heat to the cheek. Heat can worsen swelling and infection. Always use cold for dental pain.
Do not ignore swelling, fever, or a bad taste. These suggest infection, which can spread quickly and needs prompt dental care.
Do not delay flying with severe untreated dental pain. Cabin pressure changes can intensify pain in an infected or abscessed tooth.

Finding a Dentist in Japan

A dental clinic is called a shika (歪科) in Japanese. Look for the kanji or for “Dental Clinic” on signage, particularly in larger cities.

Most Japanese Dental Clinics Are Appointment-Only

Unlike general medical clinics, the great majority of Japanese dental clinics operate strictly by appointment. Walk-ins for an immediate visit are usually not possible — even in cities — except at clinics that explicitly advertise emergency or international patient service. Same-day appointments are often available if you call early in the morning.

In Major Cities

English-speaking dental care is mostly concentrated in international clinics in Tokyo, Osaka, Kyoto, and a handful of other large cities. Our city guides list options:

In Regional and Rural Areas

Outside major cities, English-speaking dentists are rare. Ask your hotel or ryokan front desk to call a nearby clinic on your behalf and explain your symptoms in Japanese. Most rural dental clinics can manage standard problems (temporary filling, pain medication, simple extraction); for complex cases they may refer you to a hospital dental department.

Online Search Tips

Searching Google Maps for “dental clinic English” or “international dentist” in your area is reliable in major cities. The Japan National Tourism Organization (JNTO) also maintains a multilingual medical institution search tool that includes dentistry.

Night and Weekend Dental Emergencies

Most Japanese dental clinics close by 18:00 on weekdays and on Sundays and holidays. After-hours care is available but limited — planning ahead avoids wasted hours of pain.

Night and holiday dental emergency centers (yakan kyujitsu shika kyukyu sentaa) exist in major cities. Tokyo, Osaka, Yokohama, and Nagoya each have at least one. Hours are typically 19:00–23:00 on weekdays and a longer window on Sundays and holidays. The hotel front desk can usually look up the nearest one.
For severe swelling, fever, or difficulty swallowing or breathing, a hospital emergency department is the right choice rather than waiting for a dentist. Call 119 if symptoms are severe.
For pain only, with no swelling or fever, over-the-counter ibuprofen plus the first-aid steps above will usually carry you through to morning. See a dentist as soon as they open.

What to Expect at a Japanese Dental Clinic

A first visit at a Japanese dental clinic is usually focused on identifying the problem and providing immediate relief, with longer-term work scheduled for follow-up appointments. Knowing the flow reduces stress.

Reception. Bring your passport and travel insurance card. The medical questionnaire (monshinhyo) is usually in Japanese; a translation app handles this in a minute. Tell reception clearly that you are a visitor (kanko de kimashita) so they understand the urgency.
Initial assessment. The dentist examines the painful area and asks about the type of pain (sharp, dull, throbbing), what triggers it, and how long it has lasted.
X-ray. A small dental X-ray (rentogen) of the affected area is standard. It identifies cavities, abscesses, and problems with the tooth root that are not visible from the outside. Modern Japanese clinics use very low-dose digital X-rays.
Treatment. Common first-visit treatments for tourists include a temporary filling, drainage of an abscess (with antibiotics), pain medication, or in some cases extraction of a problem wisdom tooth. Major reconstructive work (root canal, crown, implant) usually requires multiple visits and is not realistic on a short trip.
Prescription. Some Japanese dental clinics dispense medication directly; others give you a paper prescription (shohosen) to take to a nearby pharmacy.
Payment. Due on the day. Most clinics in cities accept credit cards; smaller clinics may be cash-only. Ask about cashless billing if you have travel insurance.

Insurance & Cost

Without Japanese national health insurance, foreign visitors typically pay full out-of-pocket prices. Travel insurance coverage of dental care varies widely — many policies cover only acute pain relief and emergency dental care, not routine work or pre-existing dental conditions. Check your policy before paying.

Approximate Costs Without Insurance

Initial dental consultation: ¥5,000 – ¥15,000
Dental X-ray (small area): ¥2,000 – ¥5,000
Temporary filling: ¥3,000 – ¥8,000
Permanent filling: ¥5,000 – ¥20,000
Tooth extraction: ¥5,000 – ¥20,000 (more for complex extractions or wisdom teeth)
Root canal treatment: ¥15,000 – ¥60,000+ (typically several visits)
Crown: ¥10,000 – ¥50,000 (depending on material; ceramic costs more than metal)
Antibiotics or pain medication: ¥1,000 – ¥3,000

Documents to Request

Always ask for an itemized receipt (ryoshusho) and, for insurance reimbursement, a brief medical certificate (shindansho) describing the diagnosis and treatment. An English-language certificate may carry an additional fee (typically ¥3,000–¥5,000) but is essential for many insurance claims.

Pharmacy Options for Toothache

Japanese pharmacies stock a range of products useful for tooth pain. None of these replace a dentist visit — they are for short-term comfort while you wait for an appointment.

Pain relievers. Acetaminophen and ibuprofen are widely available over the counter. Ibuprofen is generally more effective for dental pain because it also reduces inflammation. Follow the package dose.
Topical numbing gels. Sold for mouth ulcers and dental pain. Apply a small amount to the painful gum or tooth area for short-term numbing relief. Read instructions carefully — do not exceed recommended use.
Temporary filling kits. Available at larger drugstores. A small amount of dental putty can be molded into a lost filling cavity to protect it for a few days. Bridge to a real dentist visit as soon as possible.
Antiseptic mouthwash. Useful when gum inflammation contributes to pain. Avoid alcohol-based mouthwashes if your gums are very irritated.

How to Ask at the Pharmacy

“Ha ga itai desu” — My tooth hurts.
“Itami-dome o kudasai” — Please give me a pain reliever.
“Tsumetai mono ga shimimasu” — Cold things make it sting (helpful for describing sensitivity).
“Ima nondeiru kusuri wa . . . desu” — I am currently taking . . . (show the bottle).

When to Treat Toothache as an Emergency

Most toothaches are uncomfortable but not dangerous. The following warning signs may indicate a spreading infection or other serious problem and warrant prompt care — including a hospital emergency department after dental clinic hours.

Significant facial swelling, especially around the jaw or extending into the cheek or under the eye.
Difficulty swallowing or breathing — treat as a true emergency and call 119 immediately.
Fever (38°C / 100.4°F or higher) with dental pain. Suggests a spreading infection requiring antibiotics.
Severe pain that wakes you from sleep and is not relieved by over-the-counter pain medication.
Trauma to the mouth or face resulting in a knocked-out, broken, or loose tooth, or significant bleeding from the mouth.
A bad taste in the mouth combined with pain often signals an abscess that has begun to drain. See a dentist same-day if possible.

Prevention Tips

Most travel-related dental problems are preventable with a few simple habits.

Visit your dentist for a check-up before a long trip. Address known issues before you travel — an old filling that is showing wear is far easier to manage at home than abroad.
Keep up your usual oral hygiene. Pack a travel toothbrush, floss, and toothpaste. Brush twice a day and floss once a day even on long sightseeing days.
Be careful with sticky and hard Japanese foods. Mochi, very hard senbei (rice crackers), ice cubes, and unshelled nuts are common culprits for lost fillings and cracked teeth.
Carry a small dental kit. A travel-size pack of dental floss, a temporary filling kit, and pain relievers takes up almost no space and saves real trouble if a problem arises.
Confirm your travel insurance includes dental cover. Many policies cover only acute pain relief, not full dental work. Read the fine print before paying out of pocket abroad.

Frequently Asked Questions

Q. How do I find an English-speaking dentist in Japan?

English-speaking dental care is mostly available at international clinics in Tokyo, Osaka, Kyoto, and a few other large cities. Searching Google Maps for “dental clinic English” or “international dentist” in your area works well in major cities. Outside cities, English-speaking dentists are rare; ask your hotel front desk to call a local clinic on your behalf, and use a translation app for the consultation.

Q. Can I just walk into a Japanese dental clinic?

Usually no. Most Japanese dental clinics operate strictly by appointment, even for short visits. Same-day appointments are often available if you call early in the morning, but turning up without warning rarely works. International-friendly clinics in major cities are the most likely to accommodate walk-ins, especially for emergencies.

Q. What should I do if a filling falls out?

Avoid chewing on that side of the mouth and keep the area clean by gentle brushing and salt-water rinsing. A pharmacy temporary filling kit can protect the cavity for a few days while you arrange a dentist visit. Avoid very hot, very cold, and very sweet foods until the tooth is properly repaired.

Q. How much does it cost to see a dentist in Japan as a tourist?

An initial consultation typically costs ¥5,000–¥15,000 without insurance, with X-rays and treatment added on top. A simple extraction is usually ¥5,000–¥20,000, while a crown can be ¥10,000–¥50,000 depending on the material chosen. Many travel insurance policies cover acute dental pain but not routine work — check your policy.

Q. Are Japanese dental clinics open at night or on Sundays?

Standard dental clinics close by 18:00 on weekdays and are usually closed on Sundays and holidays. Major cities have dedicated night and holiday dental emergency centers (yakan kyujitsu shika kyukyu sentaa) with limited hours, often 19:00–23:00 on weekdays and longer windows on Sundays. Your hotel front desk can usually identify the nearest one.

Q. How do I say “my tooth hurts” in Japanese?

“Ha ga itai desu” means “my tooth hurts.” To describe sensitivity to cold, use “Tsumetai mono ga shimimasu” (cold things make it sting). To ask for pain medicine at a pharmacy, “Itami-dome o kudasai” works well. A translation app on your phone is also widely understood.

Q. Should I go to a hospital or wait for a dentist?

For pain alone, wait for a dental clinic to open and use over-the-counter pain medication in the meantime. For significant facial swelling, fever with dental pain, difficulty swallowing or breathing, or a knocked-out tooth from an injury, go to a hospital emergency department or call 119 — these can indicate a spreading infection or trauma that needs immediate care.
