One helminthic therapy self-treater noticed positive changes in her dental health.
This individual later confirmed that this effect had persisted, along with other beneficial changes.
Several individuals have reported a marked reduction in gum disease after inoculation with helminths. Their accounts can be read at the following link.
A mother has commented on the difference in dental health between her two children, one of whom has had NA from an early age to treat eczema.
Transient adverse effects
One self-treater observed a transient eruption of Lingua geographica (geographic tongue) following a dose of TTO,  and also after inoculation with NA.  A different self-treater who experienced geographic tongue also noticed less plaque following inoculation with TTO.
It has been suggested that these effects may be due to a microbial shift in the mouth relating to the introduction of helminths in the gut.
Another self-treater has mentioned experiencing mild temporary dental discomfort following inoculation with TSO.
This latter effect has also been observed in users of other species, and probably results from the action of the worms on the immune system, in which case it should reduce over time. For examples of this phenomenon in those self-treating with NA, see Recapitulation of old injuries, illnesses.
