Abstract: The present invention is directed to a dental cleaning device having, in combination, a toothbrush and a gas detecting system. The tooth brush has a brush portion and a handle portion. The brush portion of the toothbrush has dental cleaning devices allowing the user to clean teeth. The odor detection system is integrated into the toothbrush and generally comprises a gas sensor indicator for indicating presence of predetermined gas. The system allows the user to brush their teeth and either simultaneously or at differing times, detect any odors associated with bad breath. The device further allows the user a mechanism to know when bad breath causing odors are eliminated.
