Periodontal regeneration
Even a tooth you’ve been told “there’s no choice but to extract” may be saved through periodontal regeneration treatment.
- Your tooth is loose from periodontal disease, and extraction has been recommended
- Your gums have receded, and you’re concerned about how your teeth line up or look
Please talk to us, even just once.
Periodontal regeneration treatment aims to regrow the bone and periodontal tissue lost to periodontal disease. Even in severe cases that were difficult to improve with conventional periodontal treatment, combining it with regenerative therapy widens the possibility of saving the tooth. 高田馬場歯科・矯正歯科 offers periodontal regeneration treatment using the periodontal-tissue regeneration material “Emdogain” — approved by Japan’s Ministry of Health, Labour and Welfare — together with bone graft material. We propose treatment options that do everything we can to meet your wish to keep your own teeth.

What sets our periodontal regeneration treatment apart
Highly safe treatment using regenerative materials approved by Japan’s Ministry of Health, Labour and Welfare
The Emdogain we use is a periodontal-tissue regeneration gel approved by Japan’s Ministry of Health, Labour and Welfare. Its main ingredient is a protein extracted from porcine tooth buds, and it’s used worldwide as a material with high biocompatibility and a low risk of complications. Some patients feel uneasy about the word “regeneration,” but this is a treatment with a strong track record and confirmed safety.
The bone graft material we use is also a naturally derived material used worldwide, promoting bone recovery while keeping the burden on the body to a minimum.
Careful proposals for options that help save your teeth
Even a tooth diagnosed as needing extraction can sometimes be saved with periodontal regeneration treatment. We first assess the current state of your periodontal tissue with CT and X-rays, then take the time to diagnose whether regenerative treatment is suitable.
Regenerative therapy isn’t suitable for every case, but where it’s a possibility, we explain the treatment process, cost, and duration clearly, so you can make your choice with full understanding.
We also address aesthetic improvement
Periodontal regeneration treatment helps not only functional recovery but also appearance. For “gum recession,” where receding gums make teeth look longer, or for teeth that look uneven, combining a connective tissue graft (CTG) or crown lengthening can reshape the gumline and restore a natural look.
What is periodontal regeneration treatment?
Standard periodontal treatment (scaling and SRP) mainly aims to stop periodontal disease from progressing further. But when a large amount of jawbone has already been lost, basic treatment alone struggles to promote bone recovery, and tooth looseness or gum recession can remain.
Periodontal regeneration treatment aims to “regrow the tissue that’s been lost” in cases like these. By using special agents and bone graft material to promote regeneration of the periodontal tissue, we hope to help your teeth last longer.
Regenerative treatment basically involves a surgical procedure (flap surgery). We incise the gum, clear out all of the plaque and tartar underneath, apply the regenerative material, then stitch the site and wait for it to heal. Regeneration takes about half a year to a year.
Periodontal regeneration with Emdogain
Emdogain is a periodontal-tissue regeneration material developed by Biora of Sweden. Its main ingredient is a protein similar to the tissue formed as teeth erupt (enamel matrix derivative), and applying it to periodontal tissue is expected to promote regeneration of lost bone and the periodontal ligament.
After opening the gum with flap surgery to remove plaque and infected tissue, we apply Emdogain to the area we want to regenerate. We then stitch the site closed and encourage regeneration over half a year to a year. A key feature is that the tightening of the gum can also bring an aesthetic improvement.
Cases where this treatment is suitable
- You have bone loss caused by periodontal disease
- Your tooth is loose
- You’re considering having a tooth extracted
- You’re concerned about receding gums
| Treatment | Estimated cost |
|---|---|
| Emdogain (periodontal tissue regeneration therapy) | ¥110,000 (tax included) |
Connective tissue graft (CTG)
A connective tissue graft (CTG) takes a small piece of gum tissue from another site, such as the palate, and transplants it to an area where the gum has thinned or receded, increasing the volume of the gum tissue itself.
This treatment aims to “regenerate the gum” rather than the bone, and suits people who are concerned about exposed tooth roots, whose thin gums make them prone to sensitivity, or who want to reshape the gum tissue around an implant.
| Treatment | Estimated cost |
|---|---|
| Connective tissue graft (CTG) | ¥110,000 (tax included) |
Crown lengthening
Crown lengthening is a surgical procedure that trims and reshapes the gum to secure the length of the crown (the visible part of the tooth). It’s carried out to adjust the gumline so a crown can be fitted properly when damage from a cavity or a fracture extends close to the root. It’s also sometimes carried out to save a tooth that’s been diagnosed as needing extraction.
Combining crown lengthening with minor tooth movement (MTM) also makes it possible to reshape the gumline while improving tooth alignment at the same time.
| Treatment | Estimated cost |
|---|---|
| Crown lengthening | ¥55,000 (tax included) |
| Crown lengthening + minor tooth movement (MTM) | ¥110,000 (tax included) |
The process for periodontal regeneration treatment
Initial visit and detailed examination
We check the depth of your periodontal pockets and the state of any bone loss with X-rays and CT. We then judge whether regenerative treatment is suitable and explain the treatment policy, cost, and duration.
Basic periodontal treatment
Before regenerative surgery, we remove periodontal bacteria and tartar with scaling and SRP. If the mouth isn’t in good condition beforehand, the effectiveness of the surgery drops, so this stage is extremely important.
Flap surgery (applying the regenerative material)
Under anesthesia, we incise the gum and clean the root surface and the area of bone loss under direct vision. After removing infected tissue, we apply Emdogain or bone graft material, then stitch the site closed with care.
Healing period and follow-up
After stitching, we carry out regular disinfection and check on your progress. Regeneration takes about half a year to a year. Keeping your mouth clean through self-care remains important during this period.
Reassessment and maintenance
Once healing is complete, we re-examine how much the periodontal tissue has improved. Once we confirm the condition is good, we move on to regular maintenance.
Precautions after treatment
Swelling and pain can occur for a few days after surgery. Please take any prescribed pain relievers and antibiotics as instructed. We ask you to avoid strenuous exercise, alcohol, and smoking for 2–3 days after surgery.
Smoking significantly hinders the effect of regenerative treatment. Not smoking before and after surgery has a major bearing on whether the treatment succeeds, so we ask for your cooperation as much as possible.
The risk of periodontal disease recurring also remains even after regenerative treatment. Continuing regular maintenance and daily self-care is essential for protecting the regenerated tissue over the long term.
About the cost

Frequently asked questions
Is Emdogain safe?
Yes. Emdogain is a periodontal-tissue regeneration material approved by Japan’s Ministry of Health, Labour and Welfare, with a track record of use in more than 60 countries worldwide. Its main ingredient is a protein extracted from porcine tooth buds, giving it high biocompatibility and a low risk of complications. However, because it contains a porcine-derived ingredient, please let us know beforehand if you have any concerns, for religious or other reasons.
If I have regenerative treatment, will my tooth definitely be saved?
Regenerative treatment increases the chances of saving a tooth, but its effect isn’t guaranteed in every case. Factors such as the extent of bone loss, the condition of the tooth, your overall health, and your self-care after surgery all affect the outcome. We judge whether the treatment is suitable based on a detailed examination beforehand, and proceed with treatment only after explaining what effect you can expect.
Is the surgery painful?
Because the surgery is carried out under anesthesia, you generally won’t feel strong pain during the procedure. Swelling and pain can continue for a few days afterward, but for most patients this can be managed with the pain relievers we prescribe.
Can I still have regenerative treatment if I smoke?
Smokers can still have the treatment itself, but smoking is known to significantly reduce its regenerative effect. Not smoking before and after surgery directly affects the success rate, so we ask for your cooperation. If quitting smoking is difficult, please talk to your dentist.
Can periodontal disease come back after regenerative treatment?
Yes, it’s possible. Even after regenerative treatment has restored the tissue, periodontal disease will come back if plaque control isn’t good enough. Continuing regular check-ups every three months and daily brushing after treatment is extremely important for protecting your teeth over the long term.
