Keep Your Teeth for Life: A Dentist Explains The Secrets of the 8020 Rule!

This data shows the survival of the teeth who visited Tokyo International Dental Clinic Roppongi for about 20 years. Mean 16 years.

Dr.Hiroshi Miyashita presented this data in the JSAPD Open Seminar in 2o25.

“Will my teeth stay healthy forever?”

“Will they last a long time if I take good care of them?”

Everyone wonders about the lifespan of their teeth at some point.

In this post, we’ll answer these questions and more, including:

“How long should my teeth last?”
“What kind of care will make my teeth last longer?”
“Are regular checkups really necessary?”

To help you enjoy delicious meals with your own teeth for life, the director of Tokyo International Dental Roppongi will clearly explain the secrets to long-lasting dental health, based on data and evidence.

(I studied preventive dentistry in Sweden and have examined the mouths of many patients as a periodontist. I am also involved in helping those who have lost teeth to recover their function. From this experience, I am convinced that prevention is the most important thing for protecting teeth, and I am constantly updating my knowledge and skills for that purpose.)

▼ Teeth Last Longer When You [Take Good Care] of Them! ~ The Background of Increasing [8020 Achievers] ~

“It can’t be helped, teeth will fall out as you get older…”

There was a time when that was the common wisdom.

However, in recent years, the awareness of Japanese people toward their teeth has greatly improved thanks to:

The spread of [Self-Care] such as brushing and interdental cleaning
Increased rates of [Regular Dental Checkups]
Advances in [Preventive Treatments] such as fluoride application

As a result, the number of people achieving the [8020 Movement] goal of keeping 20 or more of their own teeth even at the age of 80 is steadily increasing!

▼ Cavities and Gum Disease are [Dramatically Reduced] with Regular Dental Visits! ~ Data from [Our Clinic’s Follow-Up Study] ~

“Does brushing really work?”

“Is there any point in continuing to go to the dentist?”

Some of you may be thinking that.

That’s why our clinic has investigated the dental health of patients who have been coming to our clinic continuously for the past 20 years.

As a result, an amazing fact was revealed!

[99 Patients Who Have Been Regularly Visiting Tokyo International Dental Roppongi for Oral Health Management for Over 10 and Nearly 20 Years]
[Average Follow-Up Survey of 16 Years (Conducted in 2024)]
[Out of 2630 Teeth, Only 75 Teeth (2.8%) Had to be Extracted]

In other words, on average, less than one tooth per person had to be extracted in about 20 years! We can also see that each person has around 26 teeth at this moment! Thank you, our patients, who are consistent.

Moreover, this number includes wisdom tooth extractions.

This data clearly shows that by continuing to visit the dentist, the loss of teeth due to cavities and gum disease can be drastically reduced.

▼ Why Can We Save Teeth with [Such High Probability]? ~ [Secrets of Prevention] Learned in Sweden 🇸🇪 ~

This result is supported by the knowledge and skills of [Preventive Dentistry] learned in Sweden.

Sweden is known as a developed country in preventive dentistry, and

[Fluoride Application]
[Early Detection and Treatment of Periodontal Disease]
[Thorough Self-Care Instruction]
[Professional Care by Dental Hygienists]

are thoroughly implemented.

Based on the knowledge and skills cultivated in Sweden, our clinic provides [Customized Prevention Programs] tailored to each and every patient, thereby minimizing the risk of developing cavities and gum disease.

▼ Isn’t [Regular Checkups Twice a Year] [Not Enough]!? – Prevention Based on [True Evidence] ~

Many dental clinics may recommend “regular checkups twice a year.”

But is that really enough?

According to 30 years of research data from Sweden

(Axelsson, P., Nyström, B., & Lindhe, J. (2004). The long‐term effect of a plaque control program on tooth mortality, caries and periodontal disease in adults: results after 30 years of maintenance. Journal of clinical periodontology, 31(9), 749-757.),

that’s not exactly the best solution! I’d like to tell you more.

We only started having visits every 6 months from around the announcement of the research papers, and even though they had that, it wasn’t always that way.

In the initial parts of the study, this happened every 2 months, and took about 3 years to see the results and that’s when we were able to improve the self-care parts.

In this paper, great results were obtained but, actually patients visited, once every 2 months during the first 2 years, once every 3–12 months during years 3–30.

The conclusion was that you need to have [More Than Regular Maintenance Done Every 2 Months] or it will have that effect! We make sure to follow all those trends and that’s why we ensure the best results!

By following those, you will have the best situation possible. That also means we do want to make you feel 100% comfortable as well.
