How Dental Calculus (Dental Tartar) differs From Plaque
Dental plaque and tartar, though closely related, differ significantly in composition, appearance, and treatment. Plaque is a soft, sticky biofilm of bacteria and food particles that forms on teeth daily and is easily removed through brushing and flossing. If neglected, plaque hardens into tartar, a calcified substance that adheres firmly to teeth and requires professional cleaning for removal. Plaque is colorless to pale yellow and forms within hours after eating, while tartar is hard, crusty, and ranges from yellow to black, developing over 10–14 days. Maintaining good oral hygiene is crucial to prevent plaque from turning into tartar, which can cause cavities, gum disease, and bad breath.
Appearance of Dental Calculus
Dental calculus, or tartar, is easily distinguishable by its hardened, crusty texture and varying colors, which depend on its location and the person’s habits. Above the gumline, it typically appears as yellow, white, or light brown deposits, while tartar below the gums often takes on darker shades such as brown or black, especially when mixed with blood from inflamed gums. Its rough surface readily traps pigments from foods, drinks like coffee and tea, or tobacco use, leading to further discoloration. Tartar commonly forms in areas difficult to clean, such as around the gumline, behind the lower front teeth, and near salivary glands, making it noticeable and concerning both cosmetically and for oral health.
Where and How Dental Calculus Forms
Dental calculus, or tartar, forms when dental plaque is not effectively removed through regular brushing and flossing. This process begins as plaque—a soft, sticky biofilm made of bacteria and food particles—accumulates on the teeth. Over time, minerals in your saliva harden the plaque into calculus, which adheres firmly to the teeth and often extends below the gumline. Tartar forms more readily in certain areas of the mouth, particularly where saliva flow is high and cleaning can be more challenging.
Key Areas Where Dental Calculus Forms:
- Inside of the lower front teeth: This area is closest to the submandibular and sublingual salivary glands, which deliver saliva beneath the tongue. The mineral-rich saliva makes it easier for plaque to calcify in this region.
- Outside surfaces of upper molars: These teeth are near the parotid salivary glands, which secrete saliva near the back of the cheeks. This constant exposure to saliva creates a prime environment for tartar formation.
- Around the Gumline:
The gumline is a common site for tartar buildup, both above and below the gums. Above the gumline, tartar appears as yellowish or light brown deposits, while below the gums, it can turn darker as it mixes with blood from inflamed gums. The rough texture of tartar irritates the gums and provides an ideal surface for further bacterial accumulation, often leading to gum disease if not addressed. - Between Teeth:
Tartar often forms in the spaces between teeth, especially if brushing and flossing are inconsistent or ineffective. These areas are harder to clean with a toothbrush, allowing plaque to remain undisturbed. Over time, this plaque hardens into tartar, which can only be removed professionally. The buildup between teeth increases the risk of cavities and gum irritation. - Dental Appliances:
People who wear braces, retainers, or other dental appliances are at a higher risk of tartar formation. These devices create additional surfaces where plaque can accumulate, and their placement may make it difficult to clean properly. Improperly fitted crowns or fillings can also trap food particles and bacteria, encouraging tartar to form in those areas. - Molars and Back Teeth:
The molars and back teeth are often missed during brushing due to their position in the mouth and the complexity of their grooves. These teeth are more prone to plaque buildup because food particles and bacteria can get trapped in their crevices. When left uncleaned, this plaque calcifies into tartar, making these areas hotspots for dental calculus formation.
Causes of Dental Calculus
Dental calculus, or tartar, forms when dental plaque—a sticky film of bacteria and food particles—is not removed effectively through regular brushing and flossing. The minerals in saliva, such as calcium and phosphate, harden the plaque over time, turning it into tartar. Certain habits, conditions, and dietary factors can accelerate this process, making some individuals more prone to its formation.
- Poor Oral Hygiene:
Inadequate or inconsistent oral hygiene practices are the primary cause of dental calculus. When plaque is not removed through regular brushing and flossing, it begins to harden within 24–72 hours, eventually calcifying into tartar within 10–14 days. Poor brushing technique, neglecting hard-to-reach areas, or skipping flossing allows plaque to persist on the teeth, increasing the risk of tartar buildup. Regular oral hygiene is essential to disrupt the plaque before it hardens. - Diet High in Sugary or Starchy Foods:
A diet rich in carbohydrates and sugars fuels bacteria in the mouth. These bacteria feed on sugars and starches, producing acids that contribute to plaque formation. Foods like bread, pasta, candy, and soda provide ideal conditions for bacterial growth. Frequent snacking without cleaning the teeth further increases plaque accumulation, accelerating the transition to tartar. - Smoking and Tobacco Use:
Tobacco products significantly increase the risk of tartar formation. Smoking reduces saliva flow and interferes with the mouth’s natural ability to cleanse itself, allowing plaque to linger and calcify. Smokers also tend to have more noticeable tartar due to the pigments in tobacco staining the hardened deposits. Additionally, smoking impairs gum health, exacerbating the complications associated with tartar buildup. - Dry Mouth (Xerostomia):
Saliva plays a critical role in maintaining oral health by washing away food particles and neutralizing acids. Reduced saliva flow, caused by medications, dehydration, or conditions like Sjögren’s syndrome, creates an environment conducive to plaque accumulation. Without sufficient saliva, plaque is more likely to harden into tartar. People with chronic dry mouth are particularly vulnerable to faster tartar development. - Genetic Predisposition:
Some individuals are genetically predisposed to higher concentrations of minerals in their saliva, which accelerates the calcification of plaque into tartar. While genetics alone may not cause tartar, it can make individuals more susceptible, necessitating stricter oral hygiene practices and more frequent dental cleanings. - Age:
Aging increases the risk of tartar buildup due to changes in saliva composition, reduced dexterity for effective oral hygiene, and long-standing dental restorations that may create plaque traps. Older adults may also be more likely to experience dry mouth or take medications that reduce saliva production, further contributing to tartar formation. - Dental Appliances:
Orthodontic devices like braces and retainers, or improperly fitted crowns and fillings, can create areas where food particles and plaque accumulate. These devices often make it difficult to clean teeth effectively, providing a perfect environment for plaque to calcify into tartar. Extra care and specialized cleaning tools are needed to prevent buildup in these areas.
Preventing dental calculus, or tartar, starts with effective daily oral hygiene. Since tartar forms when plaque hardens, the key is to remove plaque before it has a chance to calcify. This involves consistent brushing, flossing, and regular dental check-ups. By adopting a proactive approach, you can significantly reduce the risk of tartar buildup and the oral health problems it can cause.
- Brush Your Teeth Twice a Day:
Brushing is your first line of defense against dental calculus. Use a fluoride toothpaste to strengthen enamel and prevent plaque from hardening. Ensure you brush for at least two minutes, covering all tooth surfaces, especially near the gumline where tartar often forms. An electric toothbrush can be more effective at removing plaque, particularly in hard-to-reach areas. Replace your toothbrush or brush head every three months or when the bristles start to fray for optimal cleaning. - Floss Daily:
Flossing is essential for cleaning areas that your toothbrush can’t reach, such as between your teeth and just below the gumline. Plaque in these spaces can quickly harden into tartar if not removed. Whether you use traditional floss, floss picks, or water flossers, the goal is to dislodge food particles and plaque to keep your teeth and gums healthy. - Use Antibacterial Mouthwash:
Antibacterial mouthwash helps reduce bacteria in your mouth, lowering the risk of plaque accumulation. Swishing with an alcohol-free mouthwash not only freshens your breath but also helps reach areas brushing and flossing might miss, such as the back of your mouth. Look for a mouthwash labeled for plaque or tartar control for added protection. - Maintain a Healthy Diet:
What you eat plays a significant role in your oral health. Limiting sugary and starchy foods reduces the food supply for bacteria, which produce acids that lead to plaque. Incorporate crunchy fruits and vegetables like apples and carrots, which can help clean teeth naturally. Drinking water during and after meals helps rinse away food particles and sugars, keeping plaque at bay. - Avoid Smoking and Tobacco Products:
Smoking and tobacco use significantly increase the risk of tartar buildup by promoting faster plaque calcification. They also stain tartar, making it more noticeable and harder to remove. Quitting tobacco use not only prevents tartar but also improves overall gum health and reduces the risk of gum disease. - Schedule Regular Dental Cleanings:
Professional dental cleanings are crucial for removing plaque and tartar that daily oral hygiene might miss. Dentists and hygienists use specialized tools to clean above and below the gumline, preventing tartar buildup and associated complications. Most people benefit from a cleaning every six months, but if you’re prone to tartar, your dentist may recommend more frequent visits. - Chew Sugar-Free Gum:
Chewing sugar-free gum stimulates saliva production, which naturally washes away food particles and neutralizes acids in your mouth. Saliva plays a vital role in preventing plaque from hardening into tartar. Look for gum with xylitol, a natural sweetener that also helps combat bacteria. - Choose Tartar-Control Products:
Toothpaste and mouthwash labeled for tartar control are specially formulated to prevent plaque from hardening into tartar. These products often contain ingredients like pyrophosphates or zinc citrate, which help reduce mineral buildup. When shopping for oral care products, look for the American Dental Association (ADA) Seal of Acceptance, which ensures they have been tested for safety and effectiveness.
Dental calculus, or tartar, cannot be removed through regular brushing or flossing once it has hardened. It requires professional dental intervention to eliminate these deposits effectively. Dentists and dental hygienists use specialized tools and techniques during routine cleanings to remove tartar, both above and below the gumline. Addressing tartar buildup is essential to prevent cavities, gum disease, and other oral health complications.
1. Scaling
Scaling is the foundational procedure for removing dental calculus, targeting hardened tartar deposits on and below the gumline. Dentists and hygienists use specialized tools to scrape away these deposits. Manual scaling involves handheld instruments like scalers and curettes, which are particularly effective for smaller, more accessible tartar buildups. Alternatively, ultrasonic scaling uses vibrations combined with a water spray to break apart larger or more stubborn tartar deposits. This method is efficient, less invasive, and reduces discomfort while ensuring thorough cleaning. Scaling not only removes existing tartar but also reduces the risk of future plaque accumulation.
2. Root Planing
Root planing is a deep-cleaning procedure that goes beyond standard scaling, focusing on tartar and bacteria below the gumline. This treatment is essential for individuals with advanced gum disease or significant tartar buildup. During root planing, the dentist smooths the tooth roots to prevent bacteria from reattaching and to encourage gum tissue to heal and reattach to the teeth. This procedure is typically performed under local anesthesia to ensure patient comfort. Root planing plays a crucial role in halting the progression of gum disease and improving overall oral health.
3. Polishing
Polishing is a finishing step following tartar removal, designed to smooth the surfaces of teeth. Using a rubber cup and a gritty polishing paste, dentists remove minor stains and any remaining plaque, leaving teeth smooth and clean. Polished teeth not only feel fresh but are also less likely to attract new plaque, as a smoother surface makes it harder for bacteria to cling. Polishing also enhances the appearance of teeth, restoring their natural shine and contributing to a healthier, brighter smile.
4. Laser Therapy
Laser therapy is a modern approach to tartar removal, particularly effective in cases of severe gum disease or extensive tartar buildup below the gumline. Lasers precisely target and remove tartar while killing bacteria in the surrounding areas, minimizing the risk of infection. This technique is less invasive than traditional methods and often results in faster healing times. Laser therapy also promotes better gum health and reduces discomfort during and after treatment, making it a valuable option for advanced oral health needs.
5. Dental Cleaning Frequency
Regular dental cleanings are essential for maintaining oral health and preventing tartar buildup. For most people, biannual cleanings are sufficient to keep teeth and gums healthy. However, individuals at higher risk of tartar formation, such as smokers, those with braces, or people with dry mouth, may need more frequent visits, every three to four months. These routine cleanings allow dentists to remove any plaque or tartar before they lead to complications, ensuring optimal oral hygiene and long-term health.
6. Maintenance After Tartar Removal
After tartar is professionally removed, maintaining good oral hygiene is critical to prevent its return. Brushing twice daily with fluoride toothpaste helps remove daily plaque buildup, while flossing cleans hard-to-reach areas between teeth and near the gumline. Using an antibacterial mouthwash reduces bacteria that contribute to plaque formation. Regular dental check-ups and cleanings also ensure that any new tartar is addressed early. By combining professional care with consistent home hygiene practices, you can keep your teeth and gums healthy and free from future tartar buildup.
While professional dental cleaning is the only way to effectively remove dental calculus (tartar), there are home remedies and products that can help prevent its formation and manage plaque before it hardens. These options, when paired with consistent oral hygiene practices, can significantly improve your oral health and reduce the likelihood of tartar buildup.
- Baking Soda Toothpaste:
Baking soda, a common ingredient in some toothpastes, serves as a mild abrasive to gently scrub away plaque and surface stains. Its alkaline nature helps neutralize acids in the mouth, which can contribute to plaque formation. While it cannot remove hardened tartar, regular use of baking soda toothpaste can prevent plaque from calcifying into tartar. However, be cautious not to use pure baking soda excessively, as it can be too abrasive for enamel over time. - Oil Pulling:
Oil pulling involves swishing a tablespoon of coconut or sesame oil in your mouth for 10–15 minutes. This traditional practice is believed to reduce oral bacteria and plaque buildup. Although scientific support is limited, some people report fresher breath and cleaner-feeling teeth with regular oil pulling. It is not a substitute for brushing and flossing but can be a supplementary practice in your oral care routine. - Apple Cider Vinegar (ACV):
Diluted apple cider vinegar can be used as a mouth rinse to help loosen plaque deposits and reduce bacterial growth. However, due to its high acidity, excessive or undiluted use can erode tooth enamel over time. If you choose to use ACV, dilute it with water and limit its use to occasional rinsing, followed by rinsing with plain water to protect your enamel. - Tartar-Control Toothpaste:
Tartar-control toothpaste contains ingredients like pyrophosphates or zinc citrate that help prevent plaque from hardening into tartar. These formulations often include fluoride, which strengthens enamel and prevents cavities. Regular use can help keep plaque under control, especially in areas prone to buildup, such as around the gumline and between teeth. - Antibacterial Mouthwash:
An antibacterial mouthwash can reduce bacteria in the mouth, preventing plaque buildup. Look for alcohol-free options to avoid irritation, especially if you have sensitive gums. Rinsing twice a day with a product designed for plaque or tartar control complements brushing and flossing by reaching areas that are difficult to clean. - Flossing Tools:
Proper flossing is essential to remove plaque from between teeth and along the gumline, where tartar is most likely to form. For convenience, consider floss picks, interdental brushes, or water flossers, which are especially useful for people with braces or tight spaces between teeth. These tools ensure that hard-to-reach areas remain clean and free from plaque accumulation. - Hydration and Diet:
Drinking water throughout the day helps rinse away food particles and sugars that bacteria thrive on. Additionally, incorporating crunchy fruits and vegetables like apples, carrots, and celery into your diet can naturally clean teeth by stimulating saliva production and scrubbing surfaces as you chew. Avoid excessive sugary or starchy foods, which promote plaque growth. - Sugar-Free Gum with Xylitol:
Chewing sugar-free gum stimulates saliva production, which helps neutralize acids, wash away food particles, and prevent plaque buildup. Xylitol, a natural sweetener found in some gums, has anti-bacterial properties that inhibit the growth of cavity-causing bacteria, making it an effective tool in oral care. - Charcoal Toothpaste (Use with Caution):
Activated charcoal toothpaste has gained popularity for its ability to remove surface stains and reduce plaque. However, its abrasive nature can wear down enamel if used excessively. Charcoal toothpaste should be used sparingly and in combination with a fluoride toothpaste to ensure your enamel remains strong and healthy. - Over-the-Counter Dental Tools:
Some people use tartar scrapers or dental picks to remove plaque or minor tartar buildup at home. While these tools can be helpful, improper use may harm your gums or enamel, leading to more significant oral health issues. It is best to consult with a dentist before attempting at-home removal to ensure safe and effective use.
