always ask if the dentist is using formaldehyde in your root canal. there is a small group of disrespected dentists in the US and worldwide that use a material that has formaldehyde as it's active ingredient and also contains lead and mercury. This material is permanently sealed within the tooth and is known to cause serious and permanent damage. The FDA rejected it for approval in 1993, the ADA does not recommend it, all accredited US dental schools teach NOT to use it. watch the NBC Philadelphia video at http://www.worstrootcanalever.com
