Fluoridation does not improve dental health!!
That is the findings of all large scale studies. 

Trust the best cosmetic dentistry San Diego has, to give you that perfect smile.

The most recent large scale study was carried out in Australia in 2004. It showed there was NO difference in dental decay in 12 year children whether or not they had been receiving fluoridated water.  See Armfield Spencer Study for more detailed information.

See New Zealand Dental Health Statistics to see that dental decay rates were declining long before fluoridation was introduced, and continued to decline at the same rate regardless of whether fluoridation was started or not.

See World Health Organisation statistics to see that dental decay rates have declined all around the world, also regardless of whether fluoridation was started or not.

Fluoridation causes dental fluorosis!! Also the findings of all large scale studies.

Dental fluorosis is the outward sign that has a child has had too much fluoride.  In other words, a biomarker of over-exposure.  In New Zealand there are very little statistics kept of dental fluorosis even though the Ministry of Health know that this is an undisputed side effect of fluoridation.  

           
Very Mild dental fluorosis         Moderate Dental Fluorosis  Severe Dental Fluorosis                   Severe Dental Fluorosis

According to the Ministry of Health "The most recent New Zealand information indicates that about 29 percent of 9-year-old children in Southland who had always received fluoridated water had these changes to the tooth enamel. This level had not changed since several earlier studies undertaken in the 1980s."
http://www.moh.govt.nz/moh.nsf/indexmh/fluoridation-infantformula  However, this means that around 30% of children in fluoridated areas are getting too much fluoride! 

 

The ESR report carried out for the MOH says that there haven't been any studies on dental fluorosis since 1980 so the Southland study must be the only one since then.  It does say that dental fluorosis figures are higher than non-fluoridated areas but doesn’t specify actual levels.

 

Dr John Colquhoun published data from back in 1980 (see http://www.fluoride-journal.com/98-31-2/312103.htm)  where he states that 25% of children in fluoridated areas had some form of dental fluorosis but that he couldn't find dental fluorosis in children in non-fluoridated areas unless they had used fluoride tablets.

 

The MOH do not provide comparisons between fluoridated and non-fluoridated areas although they do refer to fluoridated areas having higher amounts.  They also say in the ESR report that figures from overseas will be comparable to here so they can safely rely on overseas data.

 

Comparisons of Dental Fluorosis Between Fluoridated and Non-fluoridated areas

 

An excerpt from the Journal Community Den Oral Epidem, 1994, gives actual comparisons.

There’s also a quote from Benefits and Risks of Water Fluoridation. An Update of the 1996 Federal-Provincial Sub-committee Report. Prepared for Ontario Ministry of Health and Long Term Care 1999 that you can see at http://www.fluoridealert.org/health/teeth/fluorosis/index.html which also has specific comparisons.

The National Health Medical Research Council in Melbourne undertook a review in 1999. It found that approximately 50% of children in fluoridated areas had some form of dental fluorosis and 30% of children in non-fluoridated areas had some form of dental fluorosis. They also found that around 4 - 8% of children had severe dental fluorosis that they considered to be an adverse health effect. See NHMRC1999.pdf page 182
