Ancient Healing
The Egyptians would use many things for healing. They would use honey to put on wounds and it was thought to disinfect and heal. The honey would burn when it was on because it was a good antibiotic. Nowadays there are other things to put on wounds that heals them faster then honey and doesn't leave a sticky residue on the skin.
Dentistry
The amount of tools they had for people were very slim. If teeth were causing problems they would be removed to fix the problem. The sand in the air would cause great damage on the teeth of people. It would get in the food and people would chew it by accident exposing the teeth to great ware and tare. The dentistry we have now is much more advanced and if a tooth is causing a problem it is not necessarily removed but filled or capped. Regular cleanings are also necessary to keep teeth clean.
