You cannot completely remove hardened plaque, also called calculus or tartar, at home. Once plaque hardens, it bonds tightly to your tooth enamel and only a dental professional using specialized metal instruments can safely scrape it off. However, you can remove the soft, sticky film of plaque before it hardens using consistent daily brushing, flossing, and proven oral care tools, which is the only effective way to prevent tartar from forming in the first place.
What Is the Difference Between Plaque and Tartar?
Plaque is a soft, colorless film of bacteria that constantly forms on your teeth. It develops within hours after you eat or drink, especially when sugars and starches mix with the natural bacteria in your mouth.
Tartar is what happens when you leave plaque on your teeth for too long. The minerals in your saliva mix with the plaque and cause it to calcify, or harden, into a rough deposit. This process can begin in as little as 48 hours if the plaque is not removed.
Once tartar forms, brushing will not remove it. The rough surface of tartar also makes it easier for more plaque to stick, creating a cycle that increases your risk of gum disease and cavities.
How To Take Plaque Off Your Teeth At Home Safely
The only safe way to remove plaque at home is to physically disrupt it before it hardens. This means using mechanical action to break up the bacterial film on your tooth surfaces and between your teeth.
Brushing twice a day with a fluoride toothpaste is the foundation. Use a soft-bristled toothbrush and angle the bristles toward the gumline at a 45-degree angle. Use gentle, circular motions rather than aggressive back-and-forth sawing, which can damage your gums and wear down enamel over time.
Flossing once a day is essential because a toothbrush cannot reach the tight spaces between your teeth. Plaque that sits between teeth is a leading cause of gum inflammation and cavities in those areas.
Some research suggests that electric toothbrushes remove plaque more effectively than manual brushes, particularly models with oscillating heads. If you struggle with technique or brushing duration, an electric brush may be a practical upgrade, but a manual brush used correctly is still effective.
Do Home Remedies Actually Remove Plaque?
Social media is full of claims about removing plaque with baking soda, hydrogen peroxide, coconut oil pulling, or scraping tools. The evidence for most of these is limited, and some can be harmful.
Baking soda is mildly abrasive and can help remove surface stains and some soft plaque when used as a toothpaste. However, it does not contain fluoride, which is critical for strengthening enamel and preventing decay. Frequent use of highly abrasive substances can also wear away enamel over time.
Oil pulling involves swishing coconut or sesame oil in your mouth for 15 to 20 minutes. Some studies suggest it may reduce bacteria in the mouth, but no clinical evidence confirms it removes existing plaque or reverses gum disease. It is not a substitute for brushing and flossing.
At-home scraping tools are dangerous. Dental scalers sold online are sharp instruments meant to be used by trained professionals who can see and feel where tartar sits below the gumline. Using them without training can cut your gums, introduce infection, or damage your enamel.
What Tools Are Proven To Help at Home?
Certain tools have stronger evidence behind them than others for controlling plaque between dental visits.
- Interdental brushes: These small brushes slide between teeth and remove plaque more effectively than floss for many people, especially when spaces are larger.
- Water flossers: These devices use a pressurized stream of water to remove food debris and some plaque. Research shows they are effective at reducing gum inflammation, though studies comparing them directly to string floss show mixed results.
- Antimicrobial mouthwashes: Rinses containing ingredients like chlorhexidine or essential oils can reduce bacteria levels in the mouth. Chlorhexidine is available by prescription and is typically used short-term because it can stain teeth. Over-the-counter essential oil rinses are a milder option.
- Fluoride toothpaste: Fluoride does not remove plaque, but it prevents the acids produced by plaque bacteria from dissolving your enamel.
No tool replaces the other. Brushing removes plaque from broad surfaces, while floss or interdental brushes handle the spaces between teeth. Mouthwash reaches areas a brush cannot but does not physically remove the sticky biofilm.
What Happens if You Leave Tartar on Your Teeth?
Leaving tartar in place is not just a cosmetic issue. The bacteria in plaque and tartar produce acids and toxins that irritate your gums.
The earliest sign of this irritation is gingivitis, which causes red, swollen, or bleeding gums. Gingivitis is reversible with improved home care and a professional cleaning.
If tartar is not removed, gingivitis can progress to periodontitis. In this more serious condition, the inflammation spreads below the gumline and begins to destroy the bone and tissue that hold your teeth in place. Periodontitis is a leading cause of tooth loss in adults and is not reversible, only manageable with ongoing treatment.
Why Professional Cleanings Are Necessary
Even with excellent home care, most people develop some tartar. This is because brushing and flossing cannot remove every single bit of plaque, especially in hard-to-reach areas or along the gumline.
A dental hygienist uses specialized instruments to scrape away tartar above and below the gumline. This process is called scaling. They may also polish your teeth to remove surface stains and smooth the enamel, which makes it harder for plaque to stick.
Most dental professionals recommend a cleaning every six months. However, your personal interval depends on your individual risk. People with a history of gum disease or heavy tartar buildup may need cleanings every three to four months, while those with excellent oral health may go longer between visits.
Can Diet Affect Plaque Buildup?
Your diet directly influences how much plaque forms and how quickly it hardens. Bacteria in your mouth feed on sugars and fermentable carbohydrates, producing acid as a byproduct.
Frequent snacking or sipping sugary drinks gives bacteria a constant food supply, which increases plaque production and acid attacks on your enamel. Sticky foods like dried fruit or chewy candy cling to teeth longer, extending the time bacteria have to produce acid.
Foods that require chewing, such as raw vegetables, stimulate saliva production. Saliva helps wash away food particles and neutralize acids, acting as your mouth’s natural defense system. Drinking water after meals also helps rinse away loose debris.
No food or drink can remove existing plaque. A diet low in added sugars and high in whole foods simply reduces the conditions that allow plaque to thrive.
Frequently Asked Questions
Can baking soda remove hard tartar at home?
No. Baking soda is too soft to break down hardened tartar that has already calcified onto your teeth. It may help scrub away soft plaque and surface stains, but only a dental professional can remove tartar.
Is it safe to scrape your own teeth with a dental tool?
No. At-home scraping tools can cut your gums, damage your enamel, and push bacteria deeper into your gums. Dental scaling requires professional training to perform safely.
Does oil pulling remove plaque from teeth?
No clinical evidence confirms that oil pulling removes existing plaque or reverses gum disease. Some studies suggest it may reduce bacteria in the mouth, but it is not a replacement for brushing and flossing.
How often should you get a professional teeth cleaning?
Most people need a professional cleaning every six months, but your specific interval depends on your oral health. Your dentist may recommend more frequent cleanings if you have gum disease or heavy tartar buildup.
