Once dental tartar forms on teeth it makes it more difficult for you to be able to brush and floss effectively. When this is the case, the acids released by the bacteria in your mouth are more likely to brake down your tooth enamel. Which then leads to tooth decay.

Tartar that forms above the gum line is even more serious.  That is because the bacteria it harbors may start to irritate and damage your gums. Given time this can lead into gingivitis which is the initial stages of gum disease. Gingivitis can usually be stopped and reversed with careful brushing, flossing and by having regular professional dental cleanings.  If gingivitis goes untreated gum disease will start to develop. Gum disease will have serious consequences if left untreated.  Studies have shown that bacteria in gum disease may contribute to heart disease as well as other health conditions.
