I’d say most folks back then had HORRIBLE teeth, as long as they kept them.
Likely everyone during that time lost all of their teeth during their 30s. Of course, the average life span back then was probably 50 something years old. lol
We can be sure there was no such thing as braces, so those with teeth just had to live with however their ‘adult teeth’ happened to grow in.
Egyptians ate a lot of bread, and the bread had bits of the stone used for grinding the grain, leading to tooth enamel loss, and (as in the case of Hatshepsut) death by tooth decay.
