Once tartar has hardened onto your teeth, you cannot fully remove it at home. Tartar (also called calculus) is mineralized plaque that bonds to enamel so firmly that only professional dental instruments can safely break it free. That said, there’s plenty you can do to slow tartar buildup, remove the soft plaque that becomes tartar, and keep your mouth healthier between dental visits.
Why Tartar Can’t Be Brushed Away
Tartar starts as plaque, the soft, sticky film of bacteria that constantly forms on your teeth. When plaque sits long enough, calcium and phosphate minerals in your saliva seep into it and crystallize. This process can begin in as little as four to eight hours, though full mineralization typically takes 10 to 12 days. Once that transformation is complete, the deposit is rock-hard and chemically bonded to your tooth surface. No amount of brushing or scraping with a fingernail will dislodge it.
Tartar forms both above and below the gumline. The visible yellowish or brownish buildup along your gum edges is supragingival tartar. The more dangerous kind, subgingival tartar, hides in the narrow space between your gums and teeth where you can’t see or reach it.
What Happens at a Professional Cleaning
A standard dental cleaning, called prophylaxis, is the only reliable way to remove tartar. During the appointment, a hygienist uses hand scalers (small hooked metal instruments) or ultrasonic devices to chip and vibrate tartar off every tooth surface, including below the gumline. Ultrasonic scalers work by producing high-frequency vibrations that shatter the bond between tartar and enamel while spraying water to flush debris away. The combination is faster and often more comfortable than hand instruments alone.
For heavier buildup or early gum disease, your dentist may recommend a deeper procedure called scaling and root planing. This involves numbing the gums with local anesthesia, removing tartar from deep beneath the gumline, and then smoothing the root surfaces so gums can reattach more tightly. Antibiotics are sometimes placed around the roots or prescribed afterward to control infection. The procedure is typically done one section of the mouth at a time, and gums usually feel tender for a few days before healing.
A standard cleaning without insurance runs roughly $100 to $250. Most people need one every six months, but if you build tartar quickly, have a history of gum disease, or manage a condition like diabetes, your dentist may suggest every three to four months.
Why DIY Scraping Tools Are Risky
Dental scrapers marketed for home use are widely available online, and social media is full of tutorials. The problem is that professional-grade scaling requires training, proper lighting, and an understanding of tooth and gum anatomy. Without those, the risks add up quickly.
- Enamel scratches. A little too much pressure with a metal scaler can gouge your enamel, creating rough spots where bacteria collect even faster.
- Soft tissue injuries. Sharp instrument tips can cut your gums, tongue, or cheeks, opening the door to infection.
- Pushing tartar deeper. Without the right angle and technique, you can accidentally shove plaque and tartar further under the gumline, worsening irritation and seeding infection in places you can’t clean.
- Incomplete removal. Leaving fragments of tartar below the gumline gives bacteria a protected surface to keep growing, which increases your risk of cavities and gum disease rather than reducing it.
What You Can Do at Home
The real power you have at home is preventing tartar from forming in the first place. Since plaque can start mineralizing within hours, consistent daily habits make a measurable difference.
Brushing With Baking Soda
Baking soda is one of the most studied ingredients for plaque removal. Clinical trials published in the Journal of the American Dental Association found that toothpastes containing baking soda removed 14% to 71% more plaque than non-baking-soda formulas across multiple mouth sites. In one crossover study of 34 participants, a single one-minute brushing with a baking soda toothpaste removed significantly more plaque than toothpastes based on hydrated silica or dicalcium phosphate. It’s low in abrasiveness, inexpensive, and has mild antibacterial properties against oral bacteria. Important distinction: baking soda is effective at removing soft plaque before it hardens. It will not dissolve or chip away existing tartar.
Tartar-Control Toothpaste
Toothpastes labeled “tartar control” contain ingredients that slow mineralization. The most common active agents are pyrophosphates, zinc salts, and sodium hexametaphosphate. Zinc salts interfere with the crystal formation that turns plaque into calcite. Sodium hexametaphosphate has shown anti-calculus benefits as high as 55% greater than regular toothpaste in clinical investigations. These products won’t remove tartar that already exists, but they can meaningfully slow how fast new deposits form between cleanings.
Flossing and Rinsing
Tartar tends to concentrate in the spots your toothbrush misses: between teeth, along the gumline, and behind your lower front teeth (where saliva ducts deliver a steady supply of minerals). Daily flossing clears plaque from those tight spaces before it has a chance to calcify. An antiseptic mouthwash adds another layer of bacterial control, though it’s a supplement to brushing and flossing, not a replacement.
What Happens If Tartar Stays
Tartar isn’t just a cosmetic problem. Its rough, porous surface gives bacteria a permanent foothold that your immune system can’t clear on its own. Left in place, tartar below the gumline triggers a chain of events that progresses from mild gum inflammation (gingivitis) to full periodontal disease.
As bacteria multiply in the sheltered environment beneath the gumline, the body’s inflammatory response starts breaking down the tissues that hold teeth in place. The gums pull away from the teeth, forming deeper pockets that trap even more bacteria and tartar. Over time, the jawbone itself begins to resorb. Dentists measure these periodontal pockets with a tiny probe. Healthy pockets are one to three millimeters deep. Once they reach four millimeters or more, the damage is considered significant. Advanced periodontitis is the leading cause of tooth loss in adults, and the bone loss it causes is irreversible.
The good news is that this progression takes months to years and is largely preventable. Regular professional cleanings remove the tartar that fuels the cycle, and consistent brushing and flossing keep plaque from building back up between visits. If you notice bleeding gums, persistent bad breath, or visible brownish deposits on your teeth, those are signs tartar is already present and a cleaning is overdue.
