What Are Tartar and How Do They Form?

8h ago

Tartar, also known as dental calculus, is a hardened deposit that forms on your teeth when plaque isn’t removed promptly. It can lead to gum disease, tooth discoloration, and persistent bad breath. In this article, we explore the causes of tartar formation, the risks it presents, and how you can prevent it — especially with the help of modern tools like the BrushO AI-powered toothbrush.

Understanding the Basics: What Is Tartar?

Tartar is a calcified substance that forms when plaque — a soft, sticky film of bacteria — hardens on your teeth. While plaque can be removed with regular brushing and flossing, tartar is more stubborn and requires professional dental cleaning. Unlike plaque, tartar is rough, porous, and usually yellow or brown in color. It often accumulates around the gumline, between teeth, and on the back surfaces of molars, where brushing is less effective.

How Does Tartar Form?

Tartar formation is a multi-step process:

Plaque Accumulation

Throughout the day, bacteria in your mouth feed on sugars from food and beverages, producing plaque.

Lack of Removal

If plaque isn’t thoroughly removed within 24–72 hours, it begins to absorb minerals from saliva.

Calcification

Over time, plaque hardens into tartar, which can no longer be brushed off at home.

Gumline Impact

Tartar at or below the gumline irritates soft tissues, leading to inflammation and gum recession.

Why Is Tartar Harmful?

Tartar is more than a cosmetic concern — it’s a direct threat to your oral health:

 • Gum Inflammation: Traps bacteria that cause gingivitis and periodontitis.
 • Tooth Decay: Creates rough surfaces where bacteria thrive, increasing the risk of cavities.
 • Persistent Bad Breath: Harbors odor-producing bacteria.
 • Aesthetic Issues: Causes yellow or brown stains that are difficult to remove.

Left untreated, tartar buildup can eventually lead to tooth loss and systemic health issues linked to oral inflammation.

Risk Factors for Tartar Buildup

Certain factors make individuals more prone to tartar accumulation:

 • Inconsistent brushing technique or duration
 • Skipping flossing or interdental cleaning
 • High-sugar diet and frequent snacking
 • Dry mouth (low saliva production)
 • Smoking or tobacco use
 • Crooked or misaligned teeth

Prevention Starts With Precision: The Role of Smart Brushing

Manual brushing often misses hard-to-reach spots, allowing plaque to turn into tartar unnoticed. This is where AI-powered brushing tools like BrushO can make a real difference.

How BrushO Helps Prevent Tartar:

 • Zone-Based Feedback: Guides you through 6 mouth zones and 16 surfaces, ensuring nothing is missed.
 • Smart Pressure Control: Avoids overbrushing while effectively cleaning plaque-prone areas.
 • Daily Scoring and Reports: Identifies neglected zones before plaque hardens.
 • Custom Modes: Tailors brushing routines to sensitive gums, deep clean needs, or preventative care.

By enhancing both brushing technique and coverage, BrushO minimizes the window for tartar formation.

What If You Already Have Tartar?

Tartar cannot be removed by brushing alone. If it’s already present:

 • Visit Your Dentist: Only professional tools like ultrasonic scalers can remove hardened calculus.
 • Maintain a Strict Home Routine: Prevent new buildup by brushing twice daily and flossing.
 • Use Smart Tools: Reinforce good habits and eliminate recurring problem zones.

Final Thoughts

Tartar may start as a silent threat, but its impact on oral health is loud and long-lasting. The key to keeping it at bay is consistent, effective brushing — and in today’s world, that means leveraging smart technology. BrushO turns your daily brushing into a precision-based, habit-forming routine, reducing your risk of plaque turning into tartar.
