It is believed that good health depends on a healthy stomach, which in turn depends on good oral hygiene. Oral hygiene comprises of dental hygiene. A large number of dental problems are due to microbial infections caused by pathogens like those belonging to genera Streptococci, Spirochetes and Bacteroides, specifically, Streptococcus mutans, Escherichia coli and Candida are responsible for caries and pus causing diseases. Dentifrices or tooth pastes used to clean teeth, claim to have antimicrobial properties, but very little research has been conducted to investigate these claims. The present investigation presents the count of normal micro flora of commonly used ten tooth paste samples, at various intervals like; after just opening the tooth paste for first use, after 15 days of use & after using it for 30 days, with the help of Standard Plate Count Method and results compared. Almost all samples show presence of microorganisms, which defies normal health standards; on zero day, 15th and 30th day samples. Microbial count goes on increasing with the period interval, showing that it is a better idea to use small volume tooth pastes than large, family size tubes.
