bshabu,
Those garbled characters should read (in katakana) "fu" plus a small "tsu". |

(Why the hell am I reading a thread about Japanese dentists? I don't live in Japan, I've never been there - and I certainly don't know anything about Japanese dentists... Anyway...)
So why is it that my Japanese students in London have uniformly awful teeth? (Yeah yeah, I know, British people don't have the best dental reputation, but still) Is it something in their culture that lacks respect for dental care? |

Regarding fluoride, I have had 2 dentists tell me that the toothpaste in Japan doesn't contain the stuff. I was speaking to one of my Japanese colleagues who has a brother teaching in the dental school at Kyushu University and his brother states that some toothpastes do contain fluoride but only in trace amounts and that is why Japanese have such bad teeth. Japan is sort of a strange country when it comes to food and drug additives. Remember the steamed buns at the convenience stores in Osaka last year? They came from China but were found to contain a "prohibited" food additive. From newspaper accounts, Japan is the only industrialized country that bans this food additive. Another example is anti-perspirant deodorant which is also banned in Japan because it contains aluminum (in whatever form). The good thing is that you can order it through FBC and other sources. During the summers I love it when the other teachers come back from class with huge armpit stains. However, 50 years from now I may have some unforeseen ailment linked to the product... |

Sorry, but those dentists obviously can't read their own labels, or you didn't communicate with them properly. (Perhaps they meant fluoride in water; see my last comments.) No offense, but it's pretty obvious on the toothpaste labels. See these pictures if you don't agree. (The toothpaste on the far left even has NaF (sodium fluoride) next to the katakana spelled in English! The middle tube has NaF partially obscured by the price label, but it's there.)
http://www.xylitolstudy.co.kr/sub04-02-05.htm
Lion makes good cheap toothpaste with fluoride. The brands are Clinica (in Japanese) and White & White (English). In fact, it's had fluoridated toothpaste in Japan since 1948. (and Ban anti-perspirant since 1962)
http://www.lion.co.jp/en/products/html/pro0101f1.htm
Ask them what they think of the following web site from Miyazaki which clearly says (at the bottom) that "some" Japanese toothpastes have fluoride as indicated by the katakana I have already mentioned.

Sorry, but this is secondhand information, and it doesn't describe what a "trace" is. To some, this is merely a tiny amount that seems to be unmeasurable. (Heck, the weather stations report a "trace" of rain when it is less than a certain measurable amount.) UK toothpastes have about 1000-1500 parts per million (1 - 1.5 mg per gram),
http://www.bda-dentistry.org.uk/bspd/pdf/fluoride.pdf
and American & Canadian toothpastes have 4000 ppm fluoride.
http://www.fatfreekitchen.com/teeth/fluoride.html
Perhaps the biggest reason Japanese have bad teeth is that their water supply doesn't contain fluoride
http://www.fdiworldental.org/assets/pdf/informatics/japan.pdf
(as with only 10% of the UK).

I agree with Glenski. If in doupt, you can buy Aquafresh. It has fluoride. |

What Glenski said.
It constantly amazes me that so many people are content to trot out the cliches about Japanese dentists and the system here. Especially those people that've often never been to a dentist in Japan.
I've written about it before here on eslcafe, but it bears saying again evidently: under the National Health Insurance scheme, it's cheaper, faster and the standard of work is, IMO, generally higher than anything I've ever experienced in NZ, Australia or the US.
Are there bad dentists in Japan? Sure. Same as anywhere. Do they have different clinical practices to some other countries? Sure. So what? Do the Japanese have 'poorer' teeth? Depends on your standards; if you've been brought up with the grossly excessive and over-weening US-style of dental obsession, then yes. Compared to some other countries, no. Add in the prevelance of a genetic problem (melocollusia (sp?)) in the population and you've got most of an explanation.
Whatever. :) |

OK so that's in your opinion but I think I'm probably right that you are not a dentist and consequently your opinion wouldn't be as relevant as that of a dental expert.
Both my dentist in Australia and an American dentist here in Japan who did some emergency repairs for me said that dentists from various countries around the world consider the standard of Japanese dentistry to be lower than a lot of other developed countries where you would expect good dental care to be available. |

You're right, I'm not a dentist. But by the same token, I also don't have any particular barrow to push over the subject, something that "experts" sometimes do.

What did they mean by "standard"? Materials? They're clearly as good. In fact, molded platinum and gold filings are, compared to amalgam (which is the direct Australian equivilent for point of use) is much better - longer lasting, better fitting, stronger, and, in Japan, cheaper to have done. Or maybe they meant something else? Don't get me wrong - I'm not saying that one or another *is* or *isn't* better. I'm just saying that Japanese dentists are often slagged off for all the wrong reasons. Mostly, I'm just playing devil's advocate. Obviously, you use whatever or whomever you feel most comfy with. |

Actually I said it in a post way back near the start of this thread. It said:
Quote: |
My dentist there said that she finds it really weird but the Japanese are leaders in producing dentistry equipment and chemicals for things like fillings etc but they are known in the world of dentists as being WAY BEHIND in actual skill as dentists. |
My dentist in Australia doesnt use amalgam much any more. In fact whenI was back there this year she took out some of my old amalgam fillings and re-did them with groovy new white stuff which she told me was made here in Japan. I teach at a company that makes the special hi-tech white dentists chemicals that new fillings, bridges etc are done with and they are apparantly world leaders in producing it.
They make it well but don't use it well. |

What is the `genetic problem` regarding teeth that Cthluhu mentioned? Please explain.
Can`t agree that it is only the American obsession with perfect dentures that makes foreigners think the Japanese have poor teeth. I am from the UK and even people who don`t pay much attention to dental hygiene tend to usually (not always) have better teeth than the Japanese. I don`t think it is fluoride - it is a problem to do with their bone structure I believe.
There seem to be too many teeth crowding a relatively small mouth. Maybe the next time a Japanese person I barely know comments on how big my nose is, I can say `Yes, and wow you have so many teeth for that small (physically) mouth.` |

Luckily, I have never had to see a dentist over seas. One friend of mine had root canal done in Osaka and she said they did not freeze her first, which would be UBER painful!
I will wait until I go home this summer for dental work. Nothing against Asian dentists, but I have mine at home and personal preference is very important. In the past 20+ years, I have had about $25,000 CDN worth of work done to my teeth and I want the same dentist. I am VERY anal about my teeth.
as for toothpaste, again, flouride or not, I found Japanese toothpastes to be too sweet, so I had Crest and *good stuff* (IMHO) sent to me in Osaka. Hong Kong has more choices and I think better dental hygiene. |

The "bad teeth caused by lack of fluoride" thing can go both ways though - I drank fluoridated water as I grew up in the UK, and as I result I have dental fluorosis, which means that my teeth are a mild mottled yellow colour (and thus considered "bad teeth"), but strong (never had any work needed on them at all). For this reason many people in the UK oppose water fluoridation, and argue that people who want fluoride intake should buy flouride tablets.
Back to Japan, how are you measuring "bad teeth" - from their appearance, or from the amount of dental work needed on them? Just because they look bad, doesn't mean they're not strong. Does anyone know how much work Japanese people need on their teeth on average?
From foster: "$25,000 CDN worth of work done to my teeth"  |

If I tell you all the work I have had done, you would be shocked....and maybe disgusted as my one friend was....an unfortunate bike accident when I was 8 (with permanent teeth) was the cause of 90% of it. |

Something on upwards of 80% of the population has a genetic trait that makes it more difficult (not impossible, just much harder) for them to absorb and retain calcium or to metabolise flouride in teeth. It's one of the major facts driving the idea in anthropology that the "Japanese" originated from a very small (fewer than 800 is the figure I've seen suggested most often ) group of people.
If you see the people around with literally grey teeth or shadings of grey across otherwise white teeth then that's examples of it. You can look up details on google if you're interested in fuller details. |

I have a student who is a denetist and he tells me that by law he can not turn away patients. This might explain why sessions tend to be short and frequent.
Anyway, I am planning to use this thread in class so I will let you know how he responds to these issues raised. |
