Calcium hydroxide is just calcium in a basic, i.e. high pH state.
I agree with Dr Goldman that weston Price would have won a nobel prize if his research was accurate.
In many cases x-rays done after root canals show little if any bone regeneration and if this is the case the tooth needs to be extracted.
Like humans,bacteria need a food source . What do the bacteria consume in a tooth that was root canaled five years ago?They must be pretty hungry.
Dr Huggins makes some interesting points but loses some credibility when he claims that a little girl went postal after one tiny filling and when he looks at a person in a wheelchair and wonders when they got their root canals.Dr Mercola is an ostopath ,not an MD or dentist.
