Can South Korea regrow teeth? What the viral posts got wrong, and what dentists can do today
Written by KCODI medical interpreter team · English deskUpdated · 7 min read
You saw a post saying South Korea can regrow teeth. A small patch on the gum, twenty minutes a day, and a new tooth grows in. It had hundreds of thousands of views. You are missing a tooth, or facing an implant, so you searched for the clinic.
There is no clinic. Our interpreters book dental patients into Seoul clinics every week, and no Korean dentist offers tooth regrowth, because no such treatment has been approved anywhere in the world. Fact-checkers traced the patch story and found no scientific paper behind it.
The real research is happening, mostly in Japan and the UK, and it is worth understanding. So is what a dentist in Korea can do for you this year.
Where the South Korea teeth regrowth story came from
In late 2025, posts spread across social media claiming that South Korean scientists had unveiled a bioactive patch that regrows natural teeth and repairs enamel. Different versions credited different universities. None linked to a published study. News fact-checkers who looked for the source found nothing in any scientific journal and rated the claim false.
The story travelled because it mixed a true thing with an invented one. Korea does have a strong dental industry, and scientists are working on tooth regeneration. Put those in one sentence with a confident tone and an AI-generated image, and it reads like news.
- No named journal, no named lead researcher you can look up, no trial registration number.
- A product that fixes everything: cavities, enamel and whole missing teeth.
- Timelines such as available next year, with no regulator mentioned.
- The same text reposted by many accounts with different universities swapped in.
What is real: the tooth regrowth research
The serious work began at Kyoto University in Japan. Researchers found that blocking a protein called USAG-1 let extra teeth develop in mice and ferrets. A spin-off company, Toregem BioPharma, turned that into an antibody drug and began a first-in-human safety study at Kyoto University Hospital in late 2024, in healthy adult men missing at least one tooth.
The next planned study is in children born without several teeth, a condition called congenital tooth agenesis. The company has spoken of aiming for availability around 2030, for that group first. As of 2026 the drug has not been shown to regrow a tooth in a human. Separately, a team at King's College London has grown tooth-like structures in the lab, which is earlier-stage still.
| Claim | Status | Can you book it? |
|---|---|---|
| South Korean patch that regrows teeth | No published science. Rated false by fact-checkers | No |
| Antibody drug that lets a new tooth grow (Japan) | Early human trials. Safety first, then children with missing teeth from birth | No. Trial participants only, in Japan |
| Lab-grown replacement teeth (UK) | Laboratory research | No |
| Drugs that help a tooth repair small holes in dentine | Animal studies | No |
| Bone grafting to rebuild the jaw for an implant | Routine dental surgery | Yes |
| Dental implants, bridges, dentures | Routine treatment | Yes |
If the Japanese drug works, the first patients will be children with a specific genetic condition, treated in trials. Adults who lost a tooth to decay or an accident are further down the road. Anyone selling you regrowth now, in any country, is selling something else.
What a dentist in Korea can do for a missing tooth today
The practical answer is still the implant: a titanium post placed in the jaw, left to bond with the bone, then fitted with a crown. Korea places a very large number of them, and several major implant brands are made here, which is why people travel for it. Our comparison of Korean implant brands covers the names you will see on a quote.
Plan it honestly. For most people Korean dental implants mean two trips: placement first, then the crown a few months later once the bone has healed. Each trip is about five to seven days with three visits. A clinic that promises everything in one week is making the kind of claim you came here to check.
- Implant. Closest to a natural tooth in function. Needs enough bone, or a graft first.
- Bridge. Faster, no surgery, but the neighbouring teeth are ground down to hold it.
- Partial denture. Lowest cost, removable, less comfortable.
- Wait. If the gap is at the back and does not bother you, doing nothing for now is a legitimate choice. Ask the dentist what happens to the bone and the neighbouring teeth if you wait.
Should you wait for regrowth instead of getting an implant?
It is a fair question, and the answer depends on how long you are willing to live with the gap. After a tooth is lost, the jawbone in that spot slowly shrinks, and the teeth beside and above the gap can drift. A few years of waiting can turn a simple implant into one that needs a bone graft.
Nothing about an implant stops you from benefiting from future treatments elsewhere in your mouth. Dentists we work with tend to give the same advice: decide on what exists, not on a headline. Your dentist is the one to weigh this for your mouth.
How to check a dental claim before you travel
- Search for the treatment name with the word trial or the name of a regulator. Real treatments leave a paper trail.
- Ask the clinic which approval the product holds in Korea, from the MFDS, and for what use.
- Ask who performs the treatment and how many they do in a month.
- Be careful with before-and-after photos that show a result no dentist at home has heard of.
- Check that the clinic is registered to treat overseas patients. Our guide shows how to check a clinic's license in Korea.
When a claim survives those questions, it is probably real. When it does not, you have saved a flight. The full list of dental treatments we book, with estimated Seoul ranges, is on the dentist in Korea page. You can also meet the interpreters who sit beside the chair.
