Dental tartar is a hardened plaque that forms on teeth when oral bacteria are not removed regularly.
It appears as a yellowish or brown patina that adheres firmly to the enamel.
The only sure way to remove it is professional scaling performed by your dentist or dental hygienist.
Keeping your teeth clean isn't just a cosmetic issue: tartar can lead to gingivitis, tooth decay, and even tooth loss.
Understanding how it forms and how to prevent it is essential to maintaining a healthy mouth .
What is dental tartar?
Tartar ( or dental limescale ) is a mineralized form of bacterial plaque .
It is composed of dead bacteria, calcium, phosphates and salivary proteins .
Once hardened, it becomes a porous deposit that retains further bacteria and pigments.
Plaque and tartar: what's the difference?

Plaque and tartar are closely linked: plaque forms daily and, if not removed, calcifies within 24–72 hours, becoming tartar.
How to recognize tartar on your teeth
Tartar is often visible to the naked eye , but it appears progressively.
Early signs of plaque and tartar
-
Sensation of roughness or “glaze” on the teeth.
-
White or yellow filament on dental floss.
-
Persistent bad breath.
-
Yellow or brown spots near the gums or between the teeth.
-
Bleeding gums when brushing.
-
In smokers or coffee lovers, appearance of black tartar .
When tartar extends under the gum , it can form periodontal pockets , small spaces where bacteria grow and worsen inflammation.
Why tartar forms
Each mouth is home to approximately 700 species of bacteria , many of which organize themselves into a biofilm : a protective, sticky film that adheres to teeth and gums.
This biofilm makes plaque more difficult to remove and promotes its calcification thanks to the minerals present in saliva.
Main risk factors
-
Irregular oral hygiene (short brushing sessions or failure to floss).
-
Diet high in sugars and refined carbohydrates.
-
Smoking , excessive tea, coffee or red wine.
-
Dry mouth (xerostomia) due to medications or little saliva.
-
Orthodontic appliances and retainers , which hinder cleaning.
-
Chronic stress , which can alter the oral bacterial flora.
-
Genetic predisposition or diabetes.
Poor daily hygiene allows the biofilm to thicken, progressively turning into hard plaque — and then tartar.
How to remove tartar
Tartar cannot be removed at home .
Attempting to scrape or remove it with unprofessional tools can damage the enamel and irritate the gums.
Professional removal techniques
-
Ultrasonic scaler: high-frequency vibrations that break down tartar deposits above and below the gums.
-
Manual curettes and scalers: remove residues in difficult areas.
-
Scaling and root planning: deep root cleaning in case of gingivitis or periodontal pockets.
-
Final polishing: smooths teeth and reduces new plaque adhesion.
After removal
It is normal to feel some mild sensitivity for a few days.
Drinking water and maintaining good oral hygiene helps rebalance the pH and bacterial flora.
Teeth cleaning and prevention
Prevention is the best ally against tartar.
Good daily oral hygiene can reduce up to 40% the formation of new plaque.
Ideal daily routine
-
Brush your teeth 2–3 times a day for at least two minutes with fluoride toothpaste.
-
Use dental floss or interdental brushes every night.
-
Clean the tongue to reduce bacterial load.
-
Use an antibacterial mouthwash (alcohol-free).
-
Prefer an electric toothbrush over a manual one.
-
Limit sugar, alcohol and smoking.
-
Check-up every 6 months and annual scaling (or quarterly for those with gingivitis or braces).
What happens if you don't remove it
Ignoring tartar means allowing bacteria to act on the gums for a long time .
Over time, the following may appear:
-
Gum recession and increased sensitivity.
-
Cavities and enamel damage.
-
Persistent bad breath.
-
Bone loss in severe cases.
Effects on the body
Periodontal disease doesn't just affect the mouth.
Research from the NCBI and the Perio Foundation has shown that chronic gum inflammation can increase cardiovascular risk and negatively impact glycemic control in diabetic patients.
Taking care of your gums also means protecting your heart.
Frequently Asked Questions:
How often should you have your teeth professionally cleaned?
On average, every six months , but those who smoke, wear braces or have gingivitis should have it done every 3–4 months.
Can I remove tartar at home?
No. Scaling must be performed by a professional : home instruments risk damaging the enamel and gums.
Can tartar come back after cleaning?
Yes, but with a good daily routine its formation slows down considerably.
How much does tartar removal cost?
In Italy , the average price varies between €60 and €200 , depending on the clinic and the complexity of the case.
Did you know?
Plaque and tartar are not just an aesthetic problem.
The bacterial biofilm that forms them can trigger chronic inflammation also linked to systemic diseases, such as diabetes and cardiovascular disorders.
Taking care of your gums is a preventive measure for the entire body.
Dentist's advice
“Many patients underestimate tartar until it causes discomfort or sensitivity.
In reality, prevention is much easier than cure.
An extra minute of brushing a day can save you an hour of scaling.”
— Dr. Pietro Pastore, Co-founder CleanOS
When to see a dentist
Contact a professional if you notice:
-
Persistent dark or yellow spots.
-
Bleeding or receding gums.
-
Bad breath that doesn't get better.
-
Teeth sensitive to hot or cold.
A timely check-up avoids periodontal complications and keeps your smile healthy over time.
Conclusions
Oral hygiene is the first defense against infections and inflammation.
Follow a consistent routine and schedule regular check-ups: prevention is the best investment for your oral and general health .
