When can you see tar in your teeth?

You can see tar on your teeth if you smoke cigarettes or use tobacco products, as tar is a sticky substance that builds up over time. It can cause yellow or brown stains on the teeth, making them appear discolored. Regular dental hygiene practices like brushing and flossing can help reduce the buildup, but persistent use of tobacco is likely to lead to visible tar accumulation. If you notice significant staining, it's advisable to consult a dentist for cleaning and advice.
