Causes of Dental Mercury Amalgam Failure

Dr. Harold Loe, the Director of the National Institute of Dental Research ( NIDR), stated in the September, 1993 edition of “Dental Products Report”:

“That first filling is a critical step in the life of a tooth. Using amalgam for the first filling requires removing a lot of the tooth substance,

not only diseased tooth substance but healthy tooth substance as well. So, in making the undercut you sacrifice a lot, and this results in a weakened tooth.

The next thing you know the tooth breaks off, and you need a crown. Then you need to repair the crown…and so it continues to the stage where there is no more to repair and you pull the tooth.

With the first filling you should do something that can either restore the tooth or retain more healthy tooth substance. Use new materials-composites or materials you can bond to the surface without undercuts. You can do this with little removal of the tooth substance so that the core of the tooth is still there.”
