Vacuum-Tooth Brush Attributes:    
On-off switch, Vaccum power (hi-low), Easy-Empty (or disposable) fluid & debris collector cup, Ergonomic design, Battery-operated and Affordable.

Invention Summary:

There is a need for a powered toothbrush that has a built-in pump and waste container that automatically removes the liquids from the oral cavity while brushing the teeth. The removal of these potentially harmful and infectious materials aids in the prevention of pneumonia  caused by oral bacteria (via Streptococcus mutans) and other respiratory and transmittal diseases, that can be exacerbated or caused by swallowing. Current evacuation technologies are bulky and are difficult to use outside of dental offices.     

Rutgers researchers and their collaborators have developed a small vacuum device that couples with a tailored electric (battery-powered) toothbrush. This optimized toothbrush reduces the risk of infection by preventing harmful bacteria from getting into the lungs. The electric toothbrush removes plaque and foreign material from the oral cavity while the vacuum safely and simultaneously evacuates excess saliva, debris, toothpaste and fluids during brushing. This technology would be especially useful for the elderly and disabled; in nursing or hospital settings; in dentist offices; in young children; as well as for routine home use. 

Market Applications:
