Pharaonic dentists were experts with reconstruction works as there have been three instances of a dental bridges where one or more lost teeth were reattached by the use of a gold or silver wire to the surrounding teeth

  33. 33. Conclusion 33 Ancient Egyptians were pioneers in various field of science and knowledge and most probably what we know about them is just a little of what they had and more will be known and discovered through excavations, discoveries, use of technology, etc., Great appreciation to our ancestors, makers of civilization hoping to follow their lead enlighting and enriching life with useful science.
