Once tartar has formed on your teeth, you cannot remove it at home. Tartar (also called calculus) is hardened plaque that has mineralized onto tooth surfaces, and it bonds too firmly to enamel for any brush, paste, or home remedy to break it off safely. The only way to get rid of existing tartar is a professional dental cleaning. What you can do, though, is prevent new tartar from forming and understand what happens during a cleaning so you know what to expect.
Why Home Removal Doesn’t Work
Plaque is the soft, sticky film of bacteria that coats your teeth throughout the day. If plaque sits on a tooth surface long enough, minerals in your saliva harden it into tartar within about 24 to 72 hours. Once that hardening process is complete, tartar is essentially cemented to the tooth. No amount of brushing or flossing will dislodge it.
You may have seen suggestions online about using baking soda, vinegar, or citrus juice to dissolve tartar at home. These don’t hold up. Baking soda is useful for raising the pH in your mouth and slowing demineralization of enamel, but it isn’t abrasive or reactive enough to chip hardened calculus off a tooth. Vinegar and citrus juice are even worse: tooth enamel starts to break down when mouth pH drops below about 5.1 to 5.5, and acidic substances push you right into that danger zone. You’d damage your enamel before you’d touch the tartar. Scraping at tartar with sharp objects at home risks cutting your gums and scratching enamel, which actually gives plaque more rough surface to cling to.
What Happens During a Professional Cleaning
A dental hygienist removes tartar using one of two approaches, and often both in the same visit. Manual scaling uses specially shaped metal instruments to physically scrape calculus off each tooth surface, above and below the gumline. Ultrasonic scaling uses a vibrating metal tip that breaks tartar apart at high frequency while spraying water to flush debris away. A 2022 meta-analysis comparing the two methods found no significant difference in effectiveness. Both work equally well, so the choice usually comes down to the hygienist’s preference and the location of the buildup.
For most people, a routine cleaning takes 30 to 60 minutes and involves minimal discomfort. If tartar has accumulated below the gumline and gum disease has started, your dentist may recommend a deeper procedure called scaling and root planing, which cleans the root surfaces of your teeth inside periodontal pockets. This sometimes requires local anesthesia and may be done over two visits, one side of the mouth at a time.
What Happens If Tartar Stays
Tartar isn’t just a cosmetic problem. Its rough, porous surface is an ideal habitat for bacteria, and research using endoscopic visualization has shown that nearly 70% of soft tissue inflammation in deep gum pockets is associated with calculus covered by bacterial biofilm. Only about 20% of that inflammation comes from biofilm alone. In other words, tartar is far more damaging than plaque by itself.
Left in place, tartar drives a predictable progression of gum disease. In the earliest stage, pockets between tooth and gum stay shallow (4 mm or less) with minor attachment loss and up to 15% bone loss. By moderate stages, pockets deepen to 5 mm with up to a third of the surrounding bone affected. In advanced disease, pockets reach 6 mm or deeper, bone loss exceeds a third, and teeth begin to loosen or fall out. The progression rate varies from person to person, but the pattern is consistent: retained tartar fuels inflammation, and inflammation destroys the bone and tissue holding teeth in place.
How Often You Need a Cleaning
The traditional recommendation is every six months, but tartar accumulation rates vary widely. Some people produce very little calculus between visits. Others, particularly those with naturally mineral-rich saliva, heavy plaque buildup, or existing gum disease, may need cleanings every three to four months. Your dentist can gauge this by how much tartar is present at each visit and whether your gums show signs of ongoing inflammation, primarily bleeding when probed. If your gums bleed during cleanings and pocket depths aren’t improving, more frequent visits or a deeper cleaning approach may be recommended.
Preventing New Tartar From Forming
Since tartar starts as plaque, preventing tartar is really about removing plaque before it hardens. That gives you a window of roughly one to three days, which is why consistent daily habits matter more than occasional thorough cleanings at home.
Brushing
Brush twice a day for two minutes each time, paying attention to the gumline and the backs of your lower front teeth, where tartar tends to accumulate fastest due to saliva gland location. Electric toothbrushes have a measurable advantage here. In one clinical trial, plaque scores after six weeks were about 53% lower with a powered toothbrush compared to a manual one, a statistically significant difference. The consistent motion and built-in timers make it easier to clean thoroughly without relying on perfect technique.
Flossing
Floss once a day to clear plaque from the tight spaces between teeth where bristles can’t reach. These are the same spots where tartar between teeth tends to build up and where gum disease often starts. If traditional floss is awkward, interdental brushes or water flossers accomplish the same goal.
Tartar-Control Toothpaste
Toothpastes labeled “tartar control” contain ingredients that slow the mineralization of plaque into calculus. The most common active agents are pyrophosphates and zinc citrate. Zinc ions work by disrupting bacterial adhesion to tooth surfaces and reducing the acid production that feeds plaque growth. Studies on zinc citrate toothpastes have shown plaque reduction ranging from 0% to 42% depending on formulation, so results vary, but there’s a real mechanism at work. These toothpastes won’t remove existing tartar, but they can slow how quickly new deposits form between dental visits.
Diet
Sugary and starchy foods feed the bacteria in plaque, accelerating its growth. Acidic drinks, including citrus juices and sodas, lower mouth pH and promote enamel demineralization, creating rougher surfaces for plaque to grip. Drinking water after meals helps rinse away food particles and buffer acidity. Crunchy vegetables and cheese can also help by stimulating saliva flow, your mouth’s natural defense against plaque buildup.
Spots That Build Tartar Fastest
Tartar doesn’t form evenly across all your teeth. The most common locations are the inside surfaces of your lower front teeth and the outer surfaces of your upper molars. Both sit near the openings of major salivary glands, which means those teeth are constantly bathed in mineral-rich saliva. Any plaque that lingers there hardens faster than plaque elsewhere in your mouth. Giving these areas extra attention when you brush is one of the simplest ways to slow tartar accumulation between professional cleanings.
