I have gunk on my teeth. how do i get it cleaned?

Tartar: Food debris and bacteria which must be removed to avoid cavities and gum disease !

Get it off!: Gunk on teeth will lead to inflammation of the gums, leading to periodontal disease and possible tooth loss. Schedule an appointment with a dentist and get them cleaned up!

Plaque : Plaque is combo platter of food and bacteria , which can lead to gum disease and tooth decay.

Most likely plaque: The gunk on teeth you are referring to is most likely plaque. It is a biofilm that consists of hundreds of bacterial species and proteins. Chronic plaque accumulation may lead to gum diseases and when combined with sugary diets, tooth decay. Whatever the "gunk" is on your teeth, make sure you try to brush twice a day and floss at least once.

Calculus: The yellow deposits you see are called calculus. They are there due to too long a period of not having a thorough cleaning that would remove them. You may notice that the gums near the calculus are red, which is inflammation. Inflammation is dangerous because bacteria that cause it can get in your bloodstream and cause bone loss as well as increase your risk of heart disease. See your dds asap!
