Topical, UBIQUINOL, adjunctive, supplement compositions, containing amorphous calcium phosphate fluoride (ACPF), useful in: reducing oxidative stress, relieving oral discomfort and dry mouth, and remineralizing hydroxyapatite comprising: UBIQUINOL in an aqueous-free emulsion that also contains: a stabilizing composition for UBIQUINOL, spilanthes extract, a trans-oral mucosal, absorption facilitator and ACPF wherein: the emulsion forms a mucoadhesive gel in the presence of saliva that undergoes gradual saliva dissolution effecting passive diffusion of the UBIQUINOL supplement and the spilanthes extract into the oral mucosa, and remineralizing of tooth surfaces with ACPF resulting in: adjunctively increasing UBIQUINOL levels, reducing oxidative stress, regulating immune response, relieving oral discomfort and dry mouth, and remineralizing tooth surfaces.
