Once tartar has formed on your teeth, only a dental professional can fully remove it. Tartar (also called calculus) is mineralized plaque that bonds to tooth enamel so firmly that no amount of brushing, scraping, or rinsing at home will eliminate it. The good news: you can slow tartar buildup significantly between cleanings and prevent new deposits from forming.
Why You Can’t Remove Tartar at Home
Tartar starts as plaque, the soft, sticky film of bacteria that coats your teeth throughout the day. If plaque isn’t brushed or flossed away, it absorbs calcium and phosphate from your saliva and hardens into tartar in roughly two weeks. Once that mineralization happens, the deposit is essentially rock-like calcium phosphate cemented to your tooth surface. No toothbrush, mouthwash, or home remedy can break that bond without damaging the tooth underneath.
You may have seen metal dental scrapers sold online for home use. These carry real risks. A little too much force can scratch your enamel permanently. The sharp tips can cut your gums, tongue, or cheeks, opening the door to infection. Worse, inexperienced scraping can push tartar and bacteria further beneath the gumline, causing irritation and deeper infection in tissue you can’t even see. Dental hygienists train for years to use these instruments safely.
How Dentists Remove Tartar
A standard professional cleaning targets tartar above the gumline using hand scalers or ultrasonic instruments. Hand scalers are curved metal tools designed to fit the contours of each tooth and pop calculus off without scratching enamel. Ultrasonic scalers vibrate at high frequency and spray water simultaneously, breaking apart deposits and flushing debris away. For most people, this process takes 30 to 60 minutes and doesn’t require numbing.
If tartar has migrated below the gumline, your dentist may recommend a deeper procedure called scaling and root planing. This involves numbing the gums with local anesthesia, then removing tartar from the tooth roots beneath the gum tissue. After scaling, the root surfaces are smoothed (planed) so bacteria have fewer rough spots to cling to. This two-step process is the primary treatment for early to moderate gum disease and can often halt its progression before bone loss becomes severe.
What Happens If Tartar Stays
Tartar isn’t just a cosmetic problem. Its rough, porous surface gives bacteria a perfect place to multiply right against your gum tissue. Over time, those bacteria travel below the gumline where brushing and flossing can’t reach. The body’s inflammatory response to this bacterial invasion is what causes gum disease.
The progression follows a predictable path. First comes gingivitis: red, swollen gums that bleed when you brush. Gingivitis is reversible with professional cleaning and better home care. Left untreated, it can advance to periodontitis, where the infection erodes the bone supporting your teeth. Dentists measure this damage using a tiny probe to check for “pockets,” gaps between your teeth and gums where bone has been lost. Periodontitis is classified as mild, moderate, or severe based on how much bone is gone, and at its worst, it leads to tooth loss.
How to Slow Tartar Buildup Between Cleanings
Since tartar takes about two weeks to form from undisturbed plaque, your daily goal is simple: remove plaque before it mineralizes. Brushing twice a day and flossing once a day handles the bulk of it, but technique and tools matter more than most people realize.
Oscillating-rotating electric toothbrushes outperform manual brushes by a meaningful margin. In a large meta-analysis, they reduced plaque by 19% more than manual brushes and cut bleeding sites by 52%. They also outperformed sonic-style electric brushes, though by a smaller margin. If you’re prone to tartar buildup, switching to an oscillating-rotating brush is one of the highest-impact changes you can make.
Toothpastes labeled “tartar control” contain compounds like pyrophosphates and zinc citrate that interfere with the crystallization process that turns plaque into tartar. They won’t remove existing tartar, but they can meaningfully reduce how fast new deposits form. Zinc in particular has been shown to inhibit calculus formation while also helping control plaque and bad breath. Look for a tartar-control toothpaste that also contains fluoride for cavity protection.
Does Baking Soda Help?
Baking soda toothpastes do remove more plaque than non-baking-soda formulas. Five clinical studies covering over 270 participants consistently found that dentifrices containing 20% to 65% baking soda produced significantly greater plaque reductions compared to standard toothpastes. However, these studies specifically measured plaque removal, not tartar removal. Once tartar has formed, baking soda won’t dissolve it. Its value is preventive: by clearing more plaque each time you brush, less plaque is available to harden into tartar. Some baking soda toothpastes are also formulated with pyrophosphates for added tartar-fighting benefit.
Areas That Build Tartar Fastest
Tartar doesn’t form evenly across your mouth. It accumulates fastest near the openings of your salivary glands, because saliva supplies the calcium and phosphate that mineralize plaque. The two hot spots are the inside surfaces of your lower front teeth (near the sublingual glands under your tongue) and the outer surfaces of your upper molars (near the parotid glands in your cheeks). Pay extra attention to these areas when brushing and flossing. Angling your toothbrush toward the gumline at about 45 degrees helps bristles sweep plaque from the crevice where buildup starts.
How Often to Get Professional Cleanings
Every six months is the standard recommendation for people with healthy gums. If you have a history of gum disease, heavy tartar buildup, or periodontitis, your dentist may suggest cleanings every three to four months. People who form tartar quickly, sometimes due to naturally mineral-rich saliva, often benefit from more frequent visits even without active gum disease. Your dentist can assess your personal rate of accumulation and recommend a schedule that keeps tartar from reaching levels that threaten your gum and bone health.
