Full Answer

In a study described by WebMD, people with zinc poisoning due to excessive use of Fixodent and other dental adhesives experienced numbness and difficulty moving their legs. The patients then developed similar problems in their arms and progressed to balance problems. The neurological symptoms dissipated when some of the individuals discontinued use of the dental adhesive, but others still suffered some residual impairment.
