Poor oral hygiene is the main risk factor for developing plaque and tartar on teeth. Since plaque forms continually on teeth, it must be removed on a regular basis to avoid oral disease such as cavities and gum disease, as well as tartar formation. Eating foods high in sugar and starch may also increase risk of developing tartar, because the sugars in foods contribute to plaque formation.
Carol Jahn, Dentistry, answeredEveryone develops plaque on a daily basis. Missing plaque during toothbrushing, not cleaning in between your teeth, and not having your teeth cleaned on a regular basis increase your risk accumulating more plaque. Plaque is filled with bacteria and these bacteria are the main cause of gingivitis and gum disease. So the real risk isn't just that you have more buildup but that the builldup increases the chance of gingivitis and gum disease.

Some people have a "talent" for having plaque and tartar adhere to their teeth. I am not aware of one particular cause, where I can predict that one person will develop tartar compared to another one.
Seeing a dentist regularly to determine how quickly you have that buildup is a good idea. Some people can see a dentist once/year with no ill effects while others should come every 3 months!
