Islamic Interpretation of Dreams (Ibn-i Sirin):
(Setting the tooth on its edge.) To set oneâs tooth on its edge in a dream means a betrayal carried by a member of oneâs family the tooth represents.
This includes oneâs children, wife, partners, or employees.
To set oneâs teeth on their edge in a dream also could mean changes in oneâs behavior that may lead to a changing attitude on the part of such family members.
