This invention provides an oral apparatus and method capable of alleviating or curing snore and obstructive sleep apnea by applying a negative pressure through a mini oral interface to the oral cavity. The mini oral interface creates a secure connection between the interface and mouth or teeth and prevents the interface from falling off. The oral interface also provides fixation between upper and lower lips (or tooth) and prevents opening of patient's mouth during sleeping.
