Aluminum lactate is effective for treatment of dentinal hypersensitivity that was confirmed in the experiments of daily home use of a dental rinse, containing this substance. Aluminum lactate also was studied on rodents. Experiments have revealed, that subchronic exposure of this substance could lead to the memory reduce.
