When it comes to maintaining a healthy smile, understanding plaque and calculus (also known as tartar) is essential. These substances are often the root of common dental issues like cavities and gum disease—but the good news is, they’re completely preventable with proper care.
What is Plaque?
Plaque is a soft, colorless film of bacteria that constantly forms on your teeth. Every time you eat or drink—especially sugary or starchy foods—the bacteria in your mouth feed on those particles and produce acids. These acids attack your tooth enamel and can lead to decay over time.
You might not always see plaque, but you can often feel it: that fuzzy feeling on your teeth when you wake up or haven’t brushed in a while? That’s plaque buildup.
What is Calculus (Tartar)?
If plaque isn’t removed regularly through brushing and flossing, it can harden into calculus. This substance is rough, yellow or brown in color, and firmly attaches to your teeth—especially near the gum line.
Unlike plaque, calculus can’t be removed at home. It requires a professional dental cleaning using special tools. Left untreated, calculus can cause gum inflammation (gingivitis), and eventually, lead to gum disease (periodontitis), bone loss, and even tooth loss.
Why You Shouldn’t Ignore It
Plaque and calculus can be silent threats. You may not feel pain until real damage is done. That’s why regular dental cleanings are essential—even if your teeth feel fine. Removing plaque before it turns into calculus helps protect both your teeth and gums in the long run.
How to Prevent Plaque and Calculus
- Brush at least twice a day with fluoride toothpaste
- Floss daily to clean between your teeth
- Limit sugary snacks and drinks
