You cannot safely remove hardened tartar from your teeth at home. Once plaque mineralizes into that crusty, yellowish deposit along your gumline, only a dentist or dental hygienist can take it off with professional instruments. But there’s a lot you can do at home to prevent tartar from forming in the first place and to slow its buildup between cleanings.
Why Tartar Can’t Be Brushed Away
Tartar starts as plaque, the soft, sticky film of bacteria that coats your teeth throughout the day. When plaque sits undisturbed, it absorbs calcium and phosphate from your saliva and begins to harden. This mineralization happens fastest near the openings of salivary ducts, which is why tartar tends to build up behind your lower front teeth and on the outer surfaces of your upper molars.
The end result is a rock-hard deposit made mostly of calcium phosphate, calcium carbonate, and magnesium phosphate, essentially dead bacteria encased in mineral. It bonds tightly to enamel and can’t be loosened by a toothbrush, floss, or mouthwash. A dental professional uses specialized scaling tools (either handheld or ultrasonic) to chip and vibrate it off without damaging the tooth underneath.
Why DIY Scraper Kits Are a Bad Idea
Metal dental scrapers sold online might look like the tools your hygienist uses, but using them without training creates real risks. You can scratch your enamel, which leads to lasting tooth sensitivity. You can cut or tear delicate gum tissue, potentially triggering gum recession that exposes the sensitive roots of your teeth. Perhaps worst of all, you can accidentally push tartar fragments beneath the gumline, where they may cause an abscess or a deeper infection. Injuries to your cheeks, tongue, and the floor of your mouth are also common because it’s nearly impossible to see what you’re doing and apply precise pressure at the same time.
The bottom line: scraping your own teeth trades a cosmetic annoyance for problems that are harder and more expensive to fix.
What Actually Prevents Tartar Buildup
Since tartar is just mineralized plaque, the strategy is simple: remove plaque before it has a chance to harden. Here’s what makes the biggest difference.
Brush Effectively, Not Just Frequently
Brushing twice a day for two full minutes covers the basics, but technique matters more than duration. Angle your bristles at about 45 degrees toward the gumline and use short, gentle strokes. Pay extra attention to the backs of your lower front teeth and the cheek side of your upper molars, the spots where tartar accumulates fastest because of nearby saliva glands.
If you’re choosing between electric toothbrush types, oscillating-rotating models (the ones with small, round heads that spin back and forth) consistently outperform sonic toothbrushes at removing plaque between teeth. A systematic review with meta-analysis found that oscillating-rotating brushes removed significantly more interproximal plaque than sonic brushes at every time point measured, from 6 weeks through 12 weeks. The advantage was most pronounced at 8 weeks. Either type is still better than a manual brush, but if tartar buildup is your main concern, the oscillating-rotating design has the stronger evidence behind it.
Floss Daily
Your toothbrush can’t reach the tight spaces between teeth where plaque loves to hide. Flossing once a day clears these surfaces before mineralization starts. If traditional floss feels awkward, interdental brushes or water flossers accomplish the same goal. The best tool is whichever one you’ll actually use every day.
Use a Tartar-Control Toothpaste
Tartar-control toothpastes contain ingredients that interfere with the chemical process of plaque hardening. The two most common active agents work in different ways. Pyrophosphates bind to the surface of your enamel and block calcium phosphate crystals from forming, essentially making it harder for minerals in your saliva to deposit onto plaque. Zinc compounds inhibit crystal growth directly while also reducing the amount of bacterial plaque on your teeth. Neither ingredient removes tartar that already exists, but both slow new buildup when used consistently. Look for a toothpaste that lists one or both on the label.
Rinse With an Antiseptic Mouthwash
An antibacterial mouthwash reduces the total volume of plaque-forming bacteria in your mouth. It’s not a substitute for brushing and flossing, but it reaches areas you might miss, especially along the gumline and between teeth. Rinsing after brushing or after meals adds another layer of protection against plaque accumulation.
Foods and Habits That Speed Up Tartar
Sugary and starchy foods feed the bacteria that produce plaque. Frequent snacking is worse than eating larger meals because it keeps a steady supply of fuel available for bacterial growth. Smoking and chewing tobacco also accelerate tartar formation by changing the chemistry of your saliva and reducing blood flow to your gums, which makes it harder for your body to fight bacterial buildup.
Drinking water throughout the day helps wash away food particles and dilute the acids that bacteria produce. Crunchy fruits and vegetables like apples, carrots, and celery can help mechanically clear some surface plaque as you chew, though they’re no replacement for brushing.
How Often You Need Professional Cleaning
Most people benefit from a professional cleaning every six months, but if you’re prone to heavy tartar buildup, your dentist may recommend every three to four months. Some people simply produce more calcium-rich saliva, which means plaque mineralizes faster regardless of how well they brush. If you notice a rough, crusty texture along your gumline or your teeth feel gritty even after brushing, that’s tartar, and it’s time for a cleaning.
Professional scaling is quick, typically 30 to 60 minutes, and usually painless unless tartar has built up significantly below the gumline. In that case, your hygienist may numb the area for comfort. Regular cleanings prevent tartar from progressing to gum disease, where bacteria trapped under hardened deposits start breaking down the bone that holds your teeth in place.
