Episode notes
Chris Had A Wisdom Tooth Pulled On The Spot
- Chris described a severe wisdom tooth episode where he had the tooth removed immediately by a dentist while cycling to work.
- He said he would have 'cut his head off' rather than endure the pain, illustrating how intolerable toothache can be.
Why Tooth Pain Feels So Intense
- Tooth pain is especially intense because the trigeminal nerve gives the head and neck a huge proportion of sensory input.
- Xand explains the homunculus idea: the head and mouth occupy large sensory representation, so tooth signals are amplified.
The Stages Behind Toothache
- Toothache has distinct causes: dentine hypersensitivity, reversible and irreversible pulpitis, then apical infection.
- Praveen details symptoms progression: sharp stimulus pain → poorly localized longer spontaneous pain indicating irreversible damage.
