Respected Hakeem Sahib, Asslamo Alikum!
I read in a magazine that by eating raisins diseases of teeth and gums can be avoided, according to a latest research teeth will be saved from worms by eating raisins.
According to the dentistry college Chicago it is sweet and it sticks to teeth while eating but it has some anti oxidant that are really helpful for the health of gums.
