What visitors and expats ask us before booking a cleaning.
A dental cleaning in Bangkok costs 900–1,500 THB at HeySmile for scaling with polishing included. AirFlow stain removal is 1,590–1,990 THB. The check-up is included.
Often, yes. A routine cleaning is finished in one visit and takes about 30 to 45 minutes. You can go straight back to work or sightseeing afterwards. We are open every day 09:30–19:30.
Most people find it comfortable. Inflamed gums, or sensitive areas where the tooth meets the gum, can feel tender. Tell the dentist: numbing gel or local anaesthetic can be used for sensitive spots and for deep cleaning.
Scaling removes hard tartar above and below the gum line. AirFlow removes stains and soft film from coffee, tea, wine and smoking. Many patients have both in the same visit.

For comparison, 900–1,500 THB is roughly US$27–45, £20–33 or €23–39 at September 2026 exchange rates; check the rate for your own currency on the day. Prices differ from clinic to clinic in Bangkok: these are the published HeySmile prices. See the cleaning section of the price list.
Insured under Thai Social Security (ประกันสังคม)? Members can use the 900 THB per year dental benefit for scaling, fillings and extractions at HeySmile. Anything above 900 THB is paid at the clinic. Tell us when you book so the dentist can plan the visit around it.
900–1,500 THB
One visit, about 30 to 45 minutes.
An estimate from the published price list, not a quote. The check-up is included. The dentist confirms what your teeth and gums need after the examination.
They do different jobs, and most patients have both in the same visit.
Plaque that is left on the teeth hardens into tartar (calculus), which brushing cannot remove. An ultrasonic scaler breaks it off the tooth above and below the gum line, and the teeth are then polished. Scaling is also called a dental prophylaxis. Regular cleaning is how gum disease, decay and bad breath are kept in check, so it is done at almost every visit. 900–1,500 THB, polishing included.
A fine jet of water, air and powder lifts the brown and grey film left by coffee, tea, red wine and smoking, including between the teeth and around braces or retainer wires. It does not scrape the tooth. 1,590–1,990 THB, on its own or added to scaling.
AirFlow does not suit everyone. Tell the dentist beforehand if you have asthma or another long-term chest condition, kidney disease, are on a low-salt diet, take diuretics or steroids, or are pregnant. In those cases your teeth are cleaned and polished in the usual way instead.
Cleaning takes off stains that sit on the surface, so teeth often look brighter afterwards, but it does not change the natural colour of the tooth. If you want a shade change, that is teeth whitening, and it works better on teeth that have just been cleaned.
One visit, and you can go back to work or sightseeing straight afterwards.
The dentist examines your teeth and gums, checks where tartar and bleeding are, and tells you in English what your teeth need and what it costs. Nothing starts until you agree. Tell the dentist about your medical history first, in particular blood-thinning medicine, a heart valve problem or previous endocarditis, a pacemaker, diabetes, or if you are pregnant. Cleaning is safe in pregnancy, but the visit may be planned differently.
Tartar is removed from the tooth surfaces and just under the gum line with an ultrasonic scaler and hand instruments. Tell the dentist if any area feels sensitive.
The teeth are polished smooth, which is included with scaling. If you chose AirFlow, stains are lifted with the water and powder jet instead of a polishing cup.
The dentist shows you any spots you are missing when you brush, applies fluoride if you want it, and suggests when to come back. You pay at reception in cash, by card or by bank transfer and receive an itemised receipt in English.
Your dentist sets the interval from what they see: how quickly you build tartar, whether your gums bleed, and whether you smoke. The NHS advises that the gap between check-ups can be anything from 3 months to 2 years, decided by your dentist. If you have gum disease, 3 to 4 months is common.
Living in Bangkok and going home once a year? Many expats book a cleaning every six months here, which is far cheaper than waiting for a visit home.
Bleeding gums are not normal. They are usually the first sign of gum inflammation, which a cleaning and better home care can reverse. Left alone it can turn into gum disease that damages the bone holding the teeth, and that needs deep cleaning instead.

Gums can feel tender and may bleed a little when you brush, especially if they were inflamed. Teeth can be sensitive to cold for a day or two. Keep brushing gently rather than avoiding the area. Contact us if bleeding, pain or swelling gets worse, lasts more than about a week, or if you develop a fever.
Teeth pick up colour most easily just after a polish or AirFlow, so try to avoid coffee, tea, red wine, curry and smoking for the rest of the day. If the dentist applied fluoride, wait 30 minutes before eating or drinking anything.
Brush twice a day with fluoride toothpaste and clean between your teeth daily with floss or interdental brushes. That is what stops new tartar and keeps the next cleaning short.
Cleaning at HeySmile is carried out by our Thai-licensed dentists, 10 of them, who all consult in English. Meet the dentists.

“I usually go to the dentist in the United States, and this was my first time seeing a dentist abroad. I'm glad I came because I knew I could get the same level of care I'm used to at home. I really recommend it.”

At HeySmile Dental Clinic scaling costs 900–1,500 THB and includes polishing. AirFlow stain removal is 1,590–1,990 THB, on its own or added to scaling, and deep cleaning for gum disease is 1,500–8,000 THB depending on how many teeth need it. The check-up is included and the price is the same for Thai and international patients.

A routine scaling and polish takes about 30 to 45 minutes. If there is a lot of tartar, allow up to an hour. Deep cleaning for gum disease takes longer and is sometimes split over two visits.
Most people find scaling comfortable, more like vibration and cold water than pain. Inflamed gums, and sensitive areas where the tooth meets the gum, can feel tender. Tell the dentist: numbing gel or local anaesthetic can be used for sensitive spots and for deep cleaning.
Normal polishing uses a soft rubber cup and paste and is included with scaling. AirFlow sprays water, air and fine powder at the tooth, which reaches between the teeth and around braces and lifts coffee, tea, wine and smoking stains that a polishing cup leaves behind. AirFlow is 1,590–1,990 THB.
Cleaning removes stains that sit on the surface, so teeth usually look brighter and feel smoother afterwards, but it does not change the natural colour of the tooth. For a shade change you need teeth whitening, and it works better on teeth that have just been cleaned.
Scaling carried out properly by a dentist does not damage enamel: the instrument removes tartar from the tooth surface, not the tooth itself. Teeth can feel slightly loose or more sensitive for a few days after heavy tartar is removed, because the hardened tartar had been holding them together like a cast and the gums underneath were inflamed. As the gums heal this settles, and any gaps that appear are the spaces the tartar was filling.
Most adults have a cleaning every six to twelve months. Your dentist decides the interval from your gums, how fast you build tartar and whether you smoke; the NHS says the gap between check-ups can be anything from 3 months to 2 years. With gum disease, every 3 to 4 months is common.
At HeySmile your cleaning is carried out by a Thai-licensed dentist, not a hygienist. The same dentist examines your teeth and gums, does the scaling and the AirFlow, and explains what they find, all in the same visit.
