Canada - 600 kids on Ottawa dental surgery wait list

..........."The problem can develop as young as under a year of age." McConnachie said.

"I have taken kids into the operating room at one year to two years of age where we've had to take out teeth … We see at the children's hospital about 15 cases a year where a [dental] infection becomes life-threatening.".......

Nothing to do with lack of fluoride just too much sugar or acid drinks.
