Once tartar has hardened onto your teeth, you cannot safely remove it yourself. Only a dental professional with the right tools can fully remove tartar (also called calculus) without damaging your enamel or gums. But there’s a lot you can do to prevent it from forming in the first place, and understanding the process helps you know when and why professional cleaning matters.
Why You Can’t Remove Tartar at Home
Tartar starts as plaque, the soft, sticky film of bacteria that builds up on your teeth throughout the day. Plaque is easy to brush away. But if it stays on your teeth, it begins to absorb minerals from your saliva and harden into calculus, typically reaching 60% to 90% of its full mineralization within about 12 days. Once that hardening process is complete, tartar bonds to your tooth surface so firmly that no amount of brushing, scraping, or rinsing will dislodge it.
You may have seen metal dental scrapers sold online for home use. Using these is a genuinely bad idea. Dental scalers have razor-sharp tips designed to be used by trained hands with direct visibility and proper lighting. When you try to use one on yourself, you risk scratching your enamel, cutting your gum tissue, and accidentally pushing tartar beneath your gumline, where it can cause infections or gum abscesses. Gum tissue trauma from amateur scraping can also lead to gum recession, permanently exposing sensitive root surfaces. Leave the metal instruments to the professionals.
What Happens During a Professional Cleaning
A dental hygienist removes tartar using one of two main approaches: hand instruments (curettes and scalers) or ultrasonic tools that vibrate at high frequencies to break calculus apart. Many cleanings use a combination of both. Ultrasonic instruments are especially useful for reaching tight spaces like the areas between tooth roots, and they tend to be faster. Hand instruments give the hygienist more tactile control for detailed work along the gumline.
A 2022 meta-analysis comparing the two methods found no significant difference in effectiveness. Both approaches produced similar improvements in pocket depth and gum attachment after six months, with comparable side-effect profiles. So the method your hygienist chooses matters less than making sure you actually go.
Most people need a professional cleaning every six months. If you build up tartar quickly or already have gum disease, your dentist may recommend every three to four months. In some cases where buildup is severe enough to interfere with a proper exam, a full-mouth debridement (a more intensive initial cleaning) is done first.
Why Tartar Buildup Matters for Your Health
Tartar isn’t just a cosmetic issue. Its rough, porous surface gives bacteria a perfect place to multiply right against your gumline. Over time, this triggers inflammation that progresses through stages of periodontal disease. In Stage I, you might lose up to 15% of the bone supporting your teeth. Stage II involves 15% to 33% bone loss. By Stage III and IV, more than a third of that bone is gone, and teeth can loosen or require extraction.
This progression is slow, often painless in the early stages, and largely preventable with regular cleanings and good daily care. The tartar itself doesn’t dissolve or go away on its own. It only accumulates.
Preventing Tartar Before It Forms
Since you have a roughly two-week window before plaque fully hardens, your daily routine is your real defense. The goal is simple: remove plaque before it mineralizes.
Brushing twice a day is the baseline, but the tool you use makes a difference. In a clinical study comparing electric and manual toothbrushes over six weeks, the electric toothbrush group had plaque scores roughly half those of the manual group (20.5 vs. 43.8). The oscillating-rotating motion provides a more consistent force than most people achieve by hand, which is why electric brushes are often recommended for people who tend to build tartar quickly.
Flossing or using interdental brushes clears plaque from the tight spaces between teeth where your toothbrush can’t reach. These are the same spots where tartar tends to accumulate first, especially along the inner surfaces of your lower front teeth and the outer surfaces of your upper molars, both areas near salivary gland openings.
Tartar-control toothpastes contain ingredients that interfere with the crystallization process, slowing the rate at which plaque hardens. They won’t remove existing tartar, but they can meaningfully reduce new buildup between cleanings.
Does Baking Soda Help?
Baking soda won’t dissolve tartar that’s already formed, but it does appear to be unusually effective at removing soft plaque before it hardens. A review published in the Journal of the American Dental Association found that baking soda toothpastes removed significantly more plaque than conventional formulas containing other abrasives. In one crossover study, a single one-minute brushing with a baking soda toothpaste outperformed two popular conventional brands by a statistically significant margin.
Baking soda is also low in abrasiveness, mildly antibacterial against oral bacteria, and inexpensive. Using a baking soda toothpaste or occasionally brushing with a paste of baking soda and water is a reasonable addition to your routine, particularly if you’re prone to heavy buildup.
Why Some People Build Tartar Faster Than Others
If you feel like your teeth accumulate tartar no matter what you do, your saliva chemistry may be part of the explanation. Research into fast versus slow calculus formers has revealed some counterintuitive findings. People who form tartar quickly tend to have higher salivary pH and greater salivary flow, both of which increase the saturation of calcium phosphate in saliva and promote mineralization. They also harbor more bacteria that convert urea into ammonia, further raising pH and accelerating the hardening process.
Interestingly, fast tartar formers actually had lower concentrations of calcium in their saliva than slow formers. The issue isn’t how much calcium is present but how soluble it remains. In slow formers, negatively charged proteins in saliva appear to keep calcium dissolved, preventing it from depositing onto plaque. In fast formers, those proteins carry a more neutral charge, allowing calcium to precipitate more readily.
None of this means prevention is futile if you’re a fast former. It means you may need to be more diligent with brushing and flossing and more consistent about professional cleanings on a shorter schedule. Knowing you’re prone to buildup is useful information, not a sentence.
