Recently a new chemical was introduced to the press called "Keep 32".  This chemical can be added to foods or products such as toothpaste or mouthwash to kill the bacteria that erode teeth. 

The premise is that this chemical when put in the mouth kills the bacteria "streptococcus mutans" which is the principal bacteria that causes decay when mixed with sugar.  By getting rid of the bacteria, the chemical keeps your teeth cavity proof for several hours.

They are just entering the human trial phase and it will be interesting to see if this works in the mouth as well as it does in the lab.  Also it will be interesting to see what happens when subjected to the high levels of sugar that are present in the American diet.

In the 1950's when Flouride was introduced into the water of the American people we trumpeted the end of decay and in a sense it did change the landscape of dentistry but it was never able to compete with the increased sugar and acid in the American diet that started in the 1970's.

Only time will tell if this is the true end of cavities.  There are alot of facets to throwing one more chemical into the body.  For now, look into Xylitol as a natural antibacterial fighter that can help keep decay away.  Xylitol can be found in gums, toothpaste and even as a sugar substitute. 

We will keep you posted on any developments!
