Have you ever looked at the back of a tooth and noticed a dark brown or yellowish buildup that just wouldn't come off? You might think it's simply a stain, but sometimes what you're looking at is calculus, also known as tartar.

And once plaque has hardened into calculus, your regular toothbrush can't simply brush it away. In this video, we're taking a closer look at what that buildup is, why it forms, why it often appears around the back teeth, and what

can happen if it's left untreated. So, if you've ever noticed something similar on your teeth, keep watching. Let's start with the basics. Everyday, a sticky layer called plaque forms on your teeth. Plaque contains bacteria along

with food particles and other substances from your mouth. Brushing and cleaning between your teeth regularly can help remove plaque before it becomes a bigger problem. But when plaque isn't removed thoroughly, it can absorb minerals from

your saliva and gradually harden. That hardened buildup is called calculus or tartar. Unlike soft plaque, calculus is firmly attached to the tooth surface, which is why brushing alone usually isn't enough to remove it. A

professional dental cleaning is needed to safely remove hardened calculus. So, why can calculus sometimes look deep brown? The color can vary. Calculus may appear yellow, brown, or even darker depending on factors such as how long it

has been present and what it has been exposed to. Pigments from foods and drinks can contribute to staining and other substances can become incorporated into the buildup over time. That's why a dark area around the gum line or behind

a molar isn't always just a surface stain. It could be hardened calculus that has accumulated over time. And there's a reason you may notice this buildup around your back teeth. Your mers can be more difficult to clean

because they're located farther back in your mouth. Their grooves and surfaces can also make them harder to reach with a toothbrush. The area near the gum line can be another place where plaque accumulates. And because you can't

always see the back surfaces of your teeth when you look in the mirror, buildup may go unnoticed. You might only discover it when it becomes more visible or when you have a dental examination. So, should you ignore calculus if it

doesn't hurt? Not necessarily. Calculus can provide a rough surface where more plaque can accumulate and buildup around the gum line can contribute to gum irritation and inflammation. You may notice symptoms such as red or swollen

gums, bleeding when brushing, or persistent bad breath. If gum inflammation continues and isn't addressed, it can develop into more serious gum disease. That's why regular dental checkups are important even when

your teeth don't hurt. The good news is that calculus can be professionally removed. A dental professional can examine your teeth and gums and determine what type of cleaning or treatment you may need. At home,

continue brushing twice a day and cleaning between your teeth regularly to help prevent plaque from building up in the first place. And avoid trying to scrape hardened calculus off your teeth yourself, as this can damage your teeth

or gums. So, if you've noticed dark or hardened buildup that doesn't come off when brushing, don't simply assume it's a stain. Your teeth may be telling you it's time for a professional checkup. For a dental examination or cleaning,
