Abstract: The invention relates to an intraoral dispensing apparatus for rendering the breath of a person aromatically pleasant. A vesicle is disposed about and in contact with the gingiva or dental gums and contains a supply of breath deodorizing or sweetening solution, which may include medications. A valve is provided for selectively dispensing solution as desired by the user, and is activated by finger pressure on the outside of the cheek. The dispensing valve operates only selectively to release solution to avoid flavor contamination of food when eating. Filling means are provided to recharge the vesicle. An alternative model is adaptable for use with dentures and can comprise a vesicle formed from a single layer of material attached about its periphery on the gingival surface of the denture. Other alternatives include combination of the foregoing with a bite opener, temporo-mandibular joint syndrome corrector, herbst appliance, etc.
