Once tartar has formed between your teeth, you cannot safely remove it at home. Tartar is mineralized plaque, essentially a hardite deposit of calcium phosphate salts that bonds to tooth surfaces. No amount of brushing, flossing, or scraping with store-bought tools will remove it without risking damage to your teeth and gums. A dental professional is the only person who should remove tartar. But there’s a lot you can do to stop it from building up in the first place and to keep it from coming back after a cleaning.
Why Tartar Can’t Be Removed at Home
Tartar starts as soft plaque, a sticky film of bacteria and food debris that collects along the gum line and between teeth. When plaque sits undisturbed, mineral salts from your saliva gradually crystallize within it. This process, called calcification, turns soft plaque into a rock-hard deposit that essentially fuses to the tooth surface. At that point, a toothbrush or piece of floss can’t break it loose any more than they could scrape cement off a wall.
You may have seen dental scraper kits sold online for home use. These carry real risks. Without training, it’s easy to gouge enamel, cut into gum tissue, or push bacteria deeper below the gum line where it can cause infection. Even in professional settings, powered scaling instruments can scratch tooth surfaces and generate aerosols containing oral bacteria. A dentist or hygienist has the tactile feedback, magnification, and experience to work around delicate gum tissue and tooth roots safely. Attempting the same thing in your bathroom mirror with a metal pick is a different situation entirely.
What Happens During Professional Removal
A professional cleaning to remove tartar typically uses one of two approaches, and often both in the same visit. Hand scaling uses curved metal instruments called curettes that let the hygienist feel the tartar and carefully scrape it away. Ultrasonic scaling uses a vibrating tip with a water spray to break apart deposits. Ultrasonic instruments are faster and reach tight spaces more easily, which is helpful for tartar wedged between teeth or tucked below the gum line.
Hand instruments tend to leave a smoother tooth surface afterward. In one study comparing the two methods, ultrasonic scaling produced roughly twice the surface roughness on tooth crowns compared to hand instruments. This matters because rougher surfaces attract plaque more quickly. Many hygienists use ultrasonic tools first to break up heavy deposits, then follow with hand instruments to smooth things out.
If tartar has built up significantly below the gum line, you may need a deeper procedure called scaling and root planing. This goes beneath the gums to clean the root surfaces. The cost for deep cleaning runs around $150 to $350 per section of the mouth without insurance, and you may need a local anesthetic to stay comfortable. A routine cleaning for tartar that’s mostly above the gum line is typically less expensive and quicker.
Why Tartar Between Teeth Is a Bigger Problem Than It Looks
Tartar between teeth isn’t just a cosmetic issue. The rough, porous surface of tartar is an ideal home for bacteria. It traps plaque against the gum tissue in the exact spots where your toothbrush has the hardest time reaching. This leads to a predictable chain of events.
First comes gingivitis: red, swollen gums that bleed when you brush or floss. Gingivitis is fully reversible with better cleaning and professional tartar removal. But if the tartar stays, bacteria migrate deeper into the space between the tooth and gum, forming pockets. At this point, the condition becomes periodontitis, and the damage starts to include bone loss around the teeth. Early periodontitis involves bone loss of up to 15% around the affected tooth. Moderate stages reach up to 30%. In severe cases, bone loss can exceed 60%, and teeth become loose or fall out. The transition from “annoying buildup” to “irreversible bone damage” can happen quietly, without much pain, which is why regular cleanings matter even when nothing seems wrong.
How to Prevent Tartar From Coming Back
Plaque begins re-forming on clean teeth within hours of a meal. It can start mineralizing into tartar in as little as 24 to 72 hours if left undisturbed. The spaces between your teeth are the most vulnerable because they’re the hardest to clean. Your prevention strategy should focus there.
Flossing and Water Flossers
String floss is effective when used correctly, but a water flosser consistently outperforms it in studies. In one trial, string floss reduced plaque between teeth by about 63%, while a water flosser reduced it by nearly 82%. Several other studies show the same pattern, with water flossers producing greater plaque reductions between teeth. The pulsing water reaches areas that string floss can miss, especially around crowded or overlapping teeth where tartar tends to accumulate fastest. Either method works if you do it daily; a water flosser simply makes it easier, particularly if you find traditional flossing awkward or skip it because of the effort involved.
Tartar-Control Toothpaste
Tartar-control toothpastes contain ingredients that slow down the crystallization process. They won’t remove existing tartar, but they can meaningfully reduce new buildup. Toothpastes with 3.3% pyrophosphate reduce tartar accumulation by about 32% over six months. Zinc citrate formulations reduce it by around 30% over 13 weeks. These ingredients work by interfering with the mineral crystals that harden plaque into tartar. Look for “tartar control” or “anti-calculus” on the label. Note that these products only affect tartar above the gum line, not deposits that have already formed below it.
Brushing Technique
Brushing twice a day for two minutes with a soft-bristled or electric toothbrush covers the basics, but angle matters. Tilting your brush at 45 degrees toward the gum line helps bristles sweep into the crevice where plaque first accumulates. Spend extra time on the inside surfaces of your lower front teeth and the outside surfaces of your upper molars. These are the spots closest to your salivary glands, where mineral-rich saliva accelerates tartar formation.
How Often You Need Professional Cleanings
Most people do well with cleanings every six months, but if you’re a heavy tartar former, your dentist may recommend every three to four months. Some people produce more calcium-rich saliva or have tighter tooth spacing that traps more plaque, making them prone to faster buildup regardless of how well they brush. If you notice a hard, rough texture along the inside of your lower front teeth or between your back molars within weeks of a cleaning, you’re likely in this category. More frequent visits keep the deposits from reaching the point where they cause gum inflammation or start creeping below the gum line.
