Plaque can be removed at home with consistent brushing, flossing, and the right products. Tartar cannot. Once plaque hardens into tartar, which happens when mineral deposits calcify on your teeth, no amount of brushing or scraping will safely get it off. Only a dental professional with specialized instruments can do that. The good news is that nearly all tartar starts as plaque, and keeping plaque under control at home is the single most effective way to prevent tartar from forming in the first place.
Why Tartar Can’t Be Removed at Home
Plaque is a soft, sticky film of bacteria that builds up on your teeth throughout the day. If it sits long enough, minerals in your saliva bind to it and harden it into tartar (also called calculus). Tartar bonds firmly to tooth enamel and forms both above and below the gumline.
You may have seen metal dental scrapers sold online for home use. Using these is genuinely risky. Without professional training, you can scratch your enamel (causing lasting sensitivity), damage gum tissue and trigger gum recession, injure your cheeks or tongue, or accidentally push tartar beneath the gumline where it can cause abscesses and infection. The Cleveland Clinic is blunt on this point: attempting to remove tartar without a dentist can damage your teeth and make you more susceptible to cavities.
So if you already have visible tartar, a professional cleaning is the only safe path. What you can control, and what the rest of this article covers, is removing plaque before it ever reaches that stage.
Brushing: The Foundation of Plaque Removal
Brushing twice a day for two full minutes is still the most important thing you can do. But your choice of toothbrush matters more than most people realize. A large Cochrane Review found that electric toothbrushes with oscillating-rotating heads achieved about 21% greater plaque reduction and 11% greater gingivitis reduction compared to manual toothbrushes over three months of use. Even in the short term, the advantage was roughly 11% more plaque removed.
If you’re using a manual brush, you can still do an effective job, but technique becomes more important. Angle the bristles at 45 degrees toward your gumline, use short gentle strokes, and make sure you’re reaching the backs of your molars and the inside surfaces of your front teeth. These are the spots where plaque tends to accumulate fastest. Replace your brush (or brush head) every three months, or sooner if the bristles start to splay.
Baking Soda Toothpaste Works Better Than You’d Think
Baking soda is one of the most studied plaque-fighting ingredients in toothpaste, and the research consistently shows it outperforms other abrasive agents at disrupting plaque biofilm. A review published in the Journal of the American Dental Association described baking soda dentifrice as “superior in plaque removal compared with other abrasive agents.”
One reason it works so well is that it’s effective without being harsh. Pure baking soda has a Relative Dentin Abrasivity (RDA) value of just 7, and toothpastes with high concentrations of baking soda score around 30 to 35. For comparison, many conventional toothpastes land between 70 and 100. That means baking soda formulas remove plaque and stains with significantly less wear on your enamel. In one study, a baking soda toothpaste with an abrasivity score of 30 removed stains just as well as a conventional paste with a score three times higher.
If you want to try it, look for a toothpaste that lists baking soda (sodium bicarbonate) as a primary ingredient. You can also make a paste from plain baking soda and water for occasional use, though a commercial formula with fluoride offers better cavity protection for daily brushing.
Cleaning Between Your Teeth
Brushing misses roughly 40% of your tooth surfaces, specifically the tight spaces between teeth where plaque loves to hide. Flossing or using an interdental cleaner once a day is essential for reaching these areas.
If you’ve been wondering whether a water flosser can replace string floss, clinical trials suggest they perform comparably. A randomized controlled trial comparing the two found no statistically significant difference in plaque scores between water flosser users and string floss users. Both groups saw meaningful reductions in plaque over time. The best interdental tool is the one you’ll actually use every day. If string floss feels like a chore and a water flosser makes you more consistent, the water flosser is the better choice for you.
Mouthwash as a Plaque-Fighting Add-On
Mouthwash won’t replace brushing and flossing, but the right rinse adds a measurable layer of protection. Essential oil-based mouthwashes (the kind with ingredients like eucalyptol, menthol, and thymol) have solid clinical data behind them. In a randomized clinical trial, rinsing with an essential oil mouthwash reduced biofilm thickness by more than half compared to rinsing with water alone, and killed bacteria at a rate comparable to prescription-strength chlorhexidine rinse.
Chlorhexidine was still better at reducing the total area of biofilm coverage (about 20% surface coverage versus 54% for essential oils), but chlorhexidine is a prescription product that stains teeth and alters taste with prolonged use. For daily over-the-counter use, an essential oil rinse offers a strong balance of effectiveness and practicality. Swish for 30 seconds after brushing and flossing, ideally before bed.
Tartar-Control Toothpaste: How It Prevents Buildup
If you’re prone to tartar buildup, a tartar-control toothpaste can slow the process. These formulas typically contain pyrophosphates, chemicals that interfere with the way calcium and phosphate crystals form on your teeth. Since tartar is essentially crystallized calcium phosphate, pyrophosphates disrupt that crystallization before it can lock onto your enamel.
Tartar-control toothpastes won’t dissolve existing tartar, but they can meaningfully reduce how fast new deposits form between dental cleanings. This is especially useful if your dentist has told you that you’re a heavy tartar former, which is partly genetic and partly influenced by the mineral content of your saliva.
Daily Habits That Reduce Plaque Buildup
Beyond your brushing routine, a few simple habits make a noticeable difference in how much plaque accumulates throughout the day:
- Limit sugary and starchy snacking. Plaque bacteria feed on sugars and starches, producing acid that damages enamel. Fewer snacks between meals means less fuel for bacterial growth.
- Drink water after eating. Rinsing your mouth with water helps wash away food particles and dilutes the acids that plaque bacteria produce.
- Chew sugar-free gum. Chewing stimulates saliva flow, which naturally buffers acid and rinses bacteria off tooth surfaces. Gum with xylitol is particularly useful because xylitol inhibits the growth of plaque-forming bacteria.
- Don’t skip nighttime brushing. Saliva flow drops significantly while you sleep, which means plaque bacteria can thrive for hours without your body’s natural defenses working at full capacity. Brushing before bed removes the day’s buildup at the worst possible time to leave it in place.
How Often You Need Professional Cleaning
Even with a perfect home routine, some plaque will inevitably harden into tartar in hard-to-reach areas. Most people benefit from a professional cleaning every six months. If you have a history of gum disease or heavy tartar buildup, your dentist may recommend every three to four months. During a cleaning, a hygienist uses ultrasonic scalers and hand instruments to remove tartar from above and below the gumline, something no home tool can replicate safely. Think of professional cleanings as the reset that keeps your home routine effective.
