No toothpaste can remove tartar once it has formed on your teeth. Tartar is mineralized plaque, hardened with calcium carbonate and calcium phosphate to the point that it can persist on skeletal remains for thousands of years. Brushing alone cannot break that bond. However, “tartar control” toothpastes do exist, and they work by preventing new tartar from forming in the first place.
Why Tartar Can’t Be Brushed Away
Tartar starts as soft, sticky plaque, a film of bacteria that builds up on your teeth throughout the day. When that plaque sits undisturbed, bacteria raise the local pH and increase the concentration of calcium and phosphorus in your saliva. This triggers a process called biomineralization, where minerals crystallize within the plaque and lock it onto the tooth surface. The National Institute of Dental and Craniofacial Research notes that calculus can begin forming within 24 hours of plaque accumulation, though the timeline varies from person to person.
Once that mineral shell hardens, no bristle, paste, or rinse can break it loose. The Cleveland Clinic is direct about this: tartar cannot be removed with brushing and flossing. A dentist or dental hygienist must physically scrape or ultrasonically vibrate it off during a professional cleaning. If tartar has built up beneath the gum line, a deeper procedure called scaling and root planing may be needed.
What “Tartar Control” Toothpaste Actually Does
Tartar control toothpastes don’t dissolve existing tartar. They slow down the formation of new tartar by interfering with the crystallization process. The key ingredient in most formulas is pyrophosphate, a compound that blocks calcium and mineral deposits from hardening onto teeth. It works the same way derivatives of pyrophosphate are used in water heaters to prevent scale buildup in pipes.
Other anti-tartar ingredients you may see on labels include zinc citrate and sodium hexametaphosphate, which serve a similar crystal-inhibiting role. These toothpastes are most useful for people who tend to build up tartar quickly between dental visits. They won’t eliminate the need for professional cleanings, but they can reduce how much tartar accumulates in the meantime.
To carry the ADA Seal of Acceptance, a toothpaste must submit clinical data proving its safety and efficacy to the ADA Council on Scientific Affairs. Fluoride content, enamel safety, and abrasiveness (measured as RDA, which must be 250 or less) are all evaluated. If a toothpaste claims tartar control benefits and carries the Seal, those claims have been independently reviewed.
Tooth Sensitivity: A Common Side Effect
Tartar control formulas aren’t free of trade-offs. A clinical study comparing tartar control toothpaste to standard toothpaste found a statistically significant increase in tooth sensitivity among the tartar control group, while the control group reported none. The pyrophosphates and other active ingredients can irritate exposed dentin in some people, particularly if you already have receding gums or worn enamel. If you notice increased sensitivity after switching to a tartar control formula, that’s a recognized side effect worth paying attention to.
Enzyme-Based Toothpastes and Plaque
Some toothpastes use plant-derived enzymes like papain (from papaya) and bromelain (from pineapple) to break down the protein layer that plaque clings to. A randomized controlled trial found that toothpaste containing these enzymes produced significantly lower plaque scores compared to a standard formula. The test group averaged a plaque index of 0.88, versus 1.17 in the control group.
These enzymes dissolve the protein film on teeth rather than attacking mineral deposits directly. That means they’re better suited for reducing plaque and surface stains than for dealing with tartar. Still, less plaque today means less tartar tomorrow, so they can be a useful part of a prevention strategy.
Preventing Tartar Before It Starts
Since no toothpaste removes tartar, the real goal is keeping plaque from mineralizing in the first place. That means disrupting plaque before it hardens, which gives you roughly a 24-hour window on any given patch of tooth surface.
Powered toothbrushes have a measurable edge here. In a six-week clinical trial, participants using a powered toothbrush had plaque scores roughly half those of the manual brushing group (20.5 vs. 43.8), a highly significant difference. The powered group showed better plaque removal as early as two weeks in. If you’re prone to tartar buildup, switching to an electric toothbrush is one of the more impactful changes you can make.
Flossing matters for the same reason. Tartar loves to form between teeth and along the gum line, exactly the spots a toothbrush misses. Chlorhexidine mouth rinses also reduce plaque accumulation and are considered one of the most effective chemical options for calculus prevention, though they can stain teeth with long-term use.
Even with perfect home care, some people produce tartar faster than others due to differences in saliva composition and bacterial populations. Regular professional cleanings, typically every six months, remain the only way to remove the tartar that inevitably forms.
