What’s in Your Water?

December 5th, 2018

First things first…we hope everyone had a great Thanksgiving!  Hopefully those who travelled had uneventful trips with nothing approaching Planes, Trains and Automobiles.  But now it is time to return to the business of this blog, TEETH!

We are going to answer 2 questions today.  Do you know if you have fluoridated water?  And what does fluoride have to do with teeth?  

The first question is easily answered.  If you have well water, there is a very strong chance that you do NOT have fluoridated water.  If you have community water (Canton City, Massillon, etc.) then chances are you DO.  

Our second question will take a tad longer and requires some history and science.  Stay with me, it isn’t that boring.  Fluoride was first added to select water supplies in 1945, with The US Public Health Service recommending that water fluoridation be instituted nationwide in 1962 (more on that later).  

The science is very simple.  Fluoride acts much like Calcium in that, when ingested, it collects in certain areas of the body (specifically the bones and teeth).  For children whose permanent teeth are still being formed, the fluoride helps form a compound called Hydroxyapatite, and that gets incorporated into the enamel portion of the new tooth.  Hydroxyapatite makes the tooth stronger and more resistant to the formation of cavities, which is the main benefit of fluoridated water.  Adults also benefit from fluoridated water because Fluoride provides a way to ‘heal’ damaged enamel surfaces through a process called ‘remineralization.’  

Alright, hopefully you are still with me because now I can explain why we decided to talk about this in the first place.  Remember that the US Public Health Service recommended the nationwide implementation of fluoridated water (I only mentioned it 2 paragraphs ago)?  Well without going too deep into our Constitution and the concept of Federalism, local communities have the authority to determine whether their water gets fluoridated, not the Federal Government.  And every November (i.e., election time) the American Dental Association (ADA) sends a newsletter stating that some communities have decided to stop fluoridating their water supply.  It just so happens that this year multiple communities voted to stop!  Why?

It turns out there are two common reasons.  The most common one is the existence of ‘studies’ attempting to connect the presence of fluoridated water with autism and various types of cancer.  These studies are poor at best.  The other often cited reason is a fear of a government putting things into the water supply.  I really don’t feel I need to rationalize that statement…just throw away the tin-foil hats.

In reality, the effects of fluoridated water have been vigorously studied by both the government and private researchers.  And the results are quite clear.  With over 50 comprehensive studies and 25 systematic reviews (think studies of the studies), there is no strong link to cancer or autism.  Water fluoridation has been a resounding success because dental cavity rates have significantly declined since 1962.  The CDC even cited water fluoridation as one of the top 10 most significant public health programs of the 20th century!  

Ok, lets wrap this up.  Obviously we feel that fluoridated water is a tremendous benefit to a growing child’s teeth.  Teeth are going to be stronger and more resistant to cavities.  Adults also see the same benefits but at a more superficial level.  So here is some homework.  You can find out about your water supply by contacting your water company.  Ask them if the water is fluoridated, and what is the concentration.  The current recommendation is 0.7mg/L (that’s milligrams per Liter).  If you have well water, you should ask your Dentist (or Orthodontist) if supplemental vitamins would be beneficial for your kids.  

If you have any questions about this, please don’t hesitate to contact us.

What I did on Vacation

July 13th, 2018

Dr. Nate here today.  So, here we are in the middle of Summer...We sincerely hope everyone has had a great start to their Summer activities!  Our whole family just got back from our yearly beach vacation, and while we were there I was finally able to catch up on the latest Orthodontic news. 

My last post focused on a supposed revolutionary vibration device designed to make Orthodontic treatment go faster.  If you want to re-visit that, click here.  I had concluded that there was no substantial evidence this system would make teeth move faster.  And now I have some semblance of vindication...

There is an Orthodontist in England named Kevin O’Brien who writes a very good blog about Orthodontics.  He is a professor of Orthodontics and a talented writer who has made quite the name for himself, even in the US.  In his most recent post (which is here) he mentioned that the British government, namely the Advertising Standards Authority (ASA), forced the company promoting their Orthodontic vibrating device to remove their ads for a very serious reason.  Instead of summarizing, I will pull the important quote.

“The ad must not appear again in its current form.  We told OrthoAccel Technologies Inc. not to make claims that their AcceleDent device could move teeth faster and reduce the pain for brace wearers unless they held adequate evidence to support such claims.”

When I finished Dr. O’Brien’s post, and then read the full ASA document, I could hardly believe it!  And then I became frustrated for two reasons.  First, the same standards haven’t been applied here in the US.  Treatments without excellent research results should not be presented to the public through advertisements!  Secondly, as a supposed learned specialty within Dentistry, Orthodontists should be able to discern good quality research from poor research.  That is our responsibility to the public...don’t treat patients with something that doesn’t work!

If you have made it this far, you should know that I fully understand that this rant has been more cathartic for me than entertaining for you.  Selfish?  Of course.  But my (and Dr. Theresa’s and Dr. Nick’s) standards are very high when it comes to treatment decisions.  Ask us why we do this treatment, and not that one.  We will be glad to tell you, and show you the research backing it up.  

New technology is great, but not always effective.  That is an important distinction. 

Some beach vacation...
