Not sure if this relates to you, but many people who suffer from PTSD have extreme dental fear:
How could a visit to the dentist trigger memories or feelings of past abuse?
Many aspects of dental treatment have been found to symbolically represent sexual abuse for many survivors. The following conditions may trigger a repetition of earlier trauma:
being alone with a person more powerful than oneself,
being placed in a horizontal position,
having someone nearby and touching you,
having objects placed in one’s mouth,
being unable to talk or swallow, and
experiencing or anticipating pain.
Many dental experiences may remind the patient of their abuse experience in that they produce awkward sensations of suffocation, such as in the use of rubber dams, or gagging sensations, or feeling restrained in their movement.
Just food for thought.
