What Is Tartar?
Tartar is a hard, calcified deposit that forms on tooth surfaces when plaque combines with minerals in saliva and gum crevicular fluid and hardens. In medical literature, it is known as dental calculus. Chemically, it consists mainly of calcium phosphate, calcium carbonate, and magnesium phosphate. Its structure also contains dead bacterial cells and mineralized salivary proteins. Tartar has a very different structure from dental plaque, which is brushable and soft. Once mineralized, it is no longer a biofilm but a layer as hard as rock. For this reason, it can only be removed by a dentist using specialized instruments.Plaque vs. Tartar
Many patients confuse these two terms. In fact, tartar is an advanced form of plaque. They are like two stages of the same process.- Soft, sticky biofilm
- Colorless or slightly yellowish
- Forms again within 24 hours
- Removable by brushing and flossing
- Contains a living bacterial community
- Gives a "fuzzy" feeling when you run your tongue over your teeth
- Hard, mineralized deposit
- Yellow, brown, gray, or black
- Hardens from plaque in 24-72 hours
- Cannot be removed by brushing, only by a dentist
- Contains dead bacteria and minerals
- Rough, stone-like, coarse surface
How Does Tartar Form?
The formation of tartar occurs in four stages:- Plaque formation: Within hours after brushing, bacteria in the mouth form a sticky biofilm on tooth surfaces. This plaque can be removed with daily oral care.
- Mineralization begins: Uncleaned plaque begins to attract calcium and phosphate ions from saliva. Mineral ions settle into the plaque matrix.
- Calcification: Within 24-72 hours, minerals begin to encase the bacteria in the plaque and the hardening process begins. At this stage, plaque can no longer be fully removed by brushing.
- Complete tartar formation: Minerals crystallize and solidify. Bacteria become embedded in the calculus structure. New plaque now adheres more easily to this rough surface, accelerating buildup.
Types of Tartar
Tartar is divided into two main types based on its location. This distinction is important both clinically and for treatment.- Visible to the eye
- Yellowish-white color
- Formed by minerals from saliva
- Most commonly accumulates on the inner surface of lower front teeth and the outer surface of upper molars (proximity to salivary glands)
- Easily removed with an ultrasonic scaler
- Not visible, but can be detected by a dentist with a probe
- Dark brown or black color
- Formed by minerals in gum crevicular fluid
- Adheres firmly to root surfaces
- Requires deeper cleaning (curettage)
Why Does Tartar Change Color?
Tartar is initially light yellow or off-white. Over time, its color changes:- New buildup: Light yellow, whitish
- Coffee, tea, red wine drinkers: Brown
- Smokers: Brown-black
- Subgingival tartar: Dark brown or black (due to blood breakdown products)
Does Everyone Get Tartar?
No matter how good your oral care is, some tartar buildup is inevitable. However, the rate and amount of buildup varies from person to person. The reasons for this variation include:- Saliva composition: Some people's saliva contains more minerals, so faster tartar formation occurs
- Saliva flow rate: In individuals with dry mouth, plaque is not cleared, and tartar forms more easily
- Diet: Sugar and starch consumption increases plaque buildup
- Quality of oral care: Buildup accelerates if interdental areas and the gumline are neglected
- Genetic factors: Some individuals are genetically predisposed to faster calculus formation
- Smoking: Indirectly speeds up tartar formation by causing dry mouth
How Common Is Tartar?
Tartar is one of the most common oral health problems worldwide. The vast majority of the adult population has some level of tartar buildup. In individuals who have regular professional cleanings, buildup remains minimal. However, in individuals who do not have a cleaning for longer than six months, significant buildup is inevitable.Symptoms
Tartar often builds up without being noticed. This process, which is completely silent at first, eventually leads to both visual and sensory changes in your mouth. Recognizing early symptoms is valuable for seeking professional cleaning before the buildup progresses.Visual Symptoms
Sensory and Odor Symptoms
- Chronic bad breath (halitosis): Bacteria in tartar structure produce sulfur compounds. Persistent bad breath that does not go away with mouthwash is one of the most common symptoms of tartar
- Bad taste in mouth: A metallic, bitter, or spoiled taste may be constantly felt in the mouth
- Bleeding during brushing: Inflammation triggered by tartar leads to bleeding when brushing
- Bleeding and difficulty when flossing: Floss catching at certain points, bleeding
- Discomfort in gums: Mild sensitivity especially when eating or exposed to hot/cold stimuli
Advanced Stage Symptoms
When tartar is neglected for a long time, symptoms become more serious:- Noticeable gum recession: Tooth roots become exposed, teeth appear elongated
- Tooth sensitivity: Exposed root surface becomes sensitive to cold and heat
- Pocket formation: Pockets form between tooth and gum that your dentist can detect with a probe
- Pus at gum edge: Yellow-white discharge when pressure is applied to the gum as a sign of active inflammation
- Tooth looseness: In cases that have progressed to periodontitis, a slight loosening sensation in teeth
- Gap formation between teeth: Spaces between teeth as supporting tissues weaken
Which Areas Are Most Affected?
Tartar does not accumulate evenly throughout the mouth but builds up in specific areas. These areas are typically close to salivary glands or difficult to clean.- Inner (tongue-side) surfaces of lower front teeth: This is where the lower salivary gland (sublingual) opens. Tartar accumulates most here
- Outer (cheek-side) surfaces of upper molars: The upper salivary gland (parotid) is close to this area
- Between teeth: The contact point between two teeth is where the brush cannot reach. Rapid buildup occurs in people who do not floss
- Crown and bridge margins: Points where restorations meet the gum line
- Around orthodontic wires: Areas around fixed braces brackets are difficult to clean
- Crowded tooth areas: Spaces between overlapping teeth
Tips for Early Detection
There are several practical ways to notice tartar in its early stage:- Check with your tongue: Feel the inner surface of your lower front teeth with your tongue. If this area, which should be smooth, feels rough or crusty, tartar may have begun
- Check in mirror: When you open your mouth by pushing your lower jaw forward, the back surface of lower front teeth becomes visible with a mirror. Yellow-brown buildup is noticed earliest here
- Bleeding during brushing: If bleeding occurs with gentle brushing using a soft-bristled brush, there may be tartar and inflammation underneath
- Persistent bad breath: Bad breath that does not go away despite tooth brushing should be investigated
Causes
The primary cause of tartar is the failure to remove plaque before it mineralizes. However, many underlying causes and risk factors contribute to plaque buildup. Effective prevention requires a comprehensive understanding of these causes.Primary Cause: Not Cleaning Plaque in Time
If plaque is not removed daily by brushing, it hardens within 24 to 72 hours by combining with minerals in saliva. This process is irreversible. Once tartar forms, home care is no longer sufficient. Professional cleaning is required.Primary Causes
Diet-Related Causes
- Sugary and starchy consumption: Bacteria use these foods as nutrients and increase plaque production
- Frequent snacking habit: Snacking continuously throughout the day keeps the mouth in an acidic environment and accelerates plaque buildup. Frequency matters more than quantity
- Sticky foods: Foods like raisins, caramel, nuts, and cereal bars adhere to tooth surfaces and remain in contact for extended periods
- Acidic beverages: Carbonated drinks and fruit juices do not directly affect plaque buildup but soften enamel, making it easier for bacteria to settle
- Insufficient water intake: Water supports saliva production and helps naturally clear bacteria and food debris from the mouth
Saliva-Related Factors
Lifestyle Factors
- Smoking and tobacco use: Causes dry mouth, reduces saliva's protective effect, and accelerates plaque buildup. Tobacco stains also adhere more easily to tartar, creating prominent brown-black discoloration
- Alcohol consumption: Leads to dehydration and reduces saliva production
- Stress: Can lead to neglect of oral care and indirectly contribute to tartar accumulation
- Irregular sleep: Some research shows a relationship between saliva flow, overall oral health, and sleep quality
Systemic and Medication-Related Factors
- Diabetes: If blood sugar control is impaired, saliva composition may change and tartar formation can accelerate. Diabetes also increases the risk of gingivitis and periodontitis, worsening the impact of tartar
- Antihistamines: Cause dry mouth
- Antidepressants: Can reduce saliva production
- Blood pressure medications: Some classes have dry mouth as a side effect
- History of radiotherapy: Head and neck radiotherapy can permanently affect salivary glands
- Cancer treatment: Oral microflora changes during chemotherapy and radiotherapy
Orthodontic and Prosthetic Factors
- Fixed orthodontic appliances: The area around braces brackets is difficult to clean. Tartar accumulation is rapid during this period, requiring special cleaning routines
- Clear aligners: Risk is lower during clear aligner treatment because aligners are removable and teeth can be brushed normally
- Bridge and crown margins: Microscopic roughness at restoration borders creates niches for tartar
- Around implants: These are special cleaning areas requiring professional monitoring
Combined Effect of Risk Groups
Diagnostic Methods
Tartar is diagnosed easily through clinical examination, no complex tests required. Your dentist uses visual inspection, periodontal probing, and X-rays when necessary to assess both the presence and extent of tartar. The diagnosis covers not only where the tartar is located but also the condition of the underlying gums and periodontal effects.Visual Examination
Your dentist carefully examines your tooth surfaces with proper lighting. Supragingival (above the gumline) tartar is usually visible to the eye. It appears as a yellow, brown, or black crusty layer adhered to the tooth surface. During examination, these points are evaluated:- Distribution of tartar buildup: Is it localized or widespread?
- Thickness of the deposit: A thin layer or a thick coating?
- Affected areas: Inner surface of lower front teeth, outer surface of upper molars, between teeth
- Color: The color of tartar provides information about both its age and your habits
- Condition of adjacent gums: Redness, swelling, tendency to bleed
Periodontal Probing
Subgingival (below the gumline) tartar is not visible to the eye. However, it can be detected with a thin metal instrument called a periodontal probe. Your dentist uses this tool to enter the pocket between the tooth and gum to check:- Presence of tartar: Rough or hard resistant spots as the probe passes
- Depth of tartar: How far below the gum margin?
- Pocket depth: In healthy gums, the pocket is 1-3 mm. With tartar present, it is typically deeper
- Bleeding on probing (BOP): An objective indicator of underlying inflammation
Plaque Disclosing
Plaque is usually colorless and invisible to the eye. In some cases, your dentist uses a dye solution called disclosing agent. This dye binds to plaque and turns it pink or purple. This allows:- Showing which areas of your mouth have plaque buildup
- Objectively evaluating brushing effectiveness
- Demonstrating areas you missed during cleaning
- Using it as an educational tool during oral hygiene instruction
X-Rays
X-rays are not routinely necessary for tartar diagnosis because supragingival tartar is detected through visual examination and subgingival tartar through probing. However, X-rays are useful in these situations:Periodontal Assessment
Once tartar is detected, evaluating the condition of the underlying gums is essential. Tartar rarely exists alone. It usually leads to gingivitis or periodontitis. During periodontal assessment, these parameters are recorded:- Pocket depth: Six different points measured on each tooth
- Clinical attachment loss (CAL): Loss evaluated by accounting for gum recession
- Bleeding on probing (BOP): Indicator of active inflammation
- Gum recession: Presence and distribution
- Tooth mobility: According to Miller classification
- Plaque index: Objective measure of oral hygiene effectiveness
Recording and Monitoring
A thorough diagnostic process not only documents the current condition but also creates a reference for future comparisons:- Periodontal charting: The periodontal status of all teeth is recorded in a chart
- Intraoral photographs: Areas with significant buildup are photographed
- Patient education: Identified areas are explained to you, and an oral hygiene plan is developed
- Follow-up plan: The next check-up interval is determined based on the rate of buildup
What Happens If Left Untreated?
Tartar build-up may initially seem like a harmless cosmetic issue. However, over time it develops into a condition that negatively affects oral health in many ways. In this section, we discuss the short-, medium-, and long-term consequences of untreated tartar.Progression to Gingivitis and Periodontitis
The most significant consequence of untreated tartar is gum disease. This process progresses in an inevitable chain:- Onset of gingivitis: Chronic inflammation caused by tartar first leads to gingivitis. Gums become red, swollen, and start bleeding
- Chronic gingivitis: Untreated gingivitis can persist for months and create permanent changes in your gums
- Transition to periodontitis: Some cases of gingivitis eventually progress to periodontitis. From this stage onward, bone loss begins
- Bone loss and tooth loss: Long-term neglect is the most common cause of tooth loss in adults
Increased Bacterial Load
The surface of tartar is rough and provides a home for far more bacteria than a smooth tooth surface. As a result:- Existing bacterial load increases
- More pathogenic bacterial species (anaerobic bacteria) multiply
- Periodontal pathogens known as the "red complex" (P. gingivalis, T. forsythia, T. denticola) colonize
- These bacteria produce toxins and enzymes that trigger inflammation
- Immune response becomes chronic and leads to tissue destruction
Gum Recession and Root Surface Exposure
Long-term tartar accumulation causes gums to recede. The consequences:- Root surface exposure: Teeth begin to appear longer
- Tooth sensitivity: Exposed root surface is sensitive to cold and heat. Tooth sensitivity is a common complaint related to tartar
- Risk of root decay: Root surfaces lack enamel; the cementum layer is softer and more susceptible to root decay
- Aesthetic concern: Gum recession, especially in the front region, creates "black triangles" in your smile
Permanent Aesthetic Problems
Social and Psychosocial Effects
- Chronic bad breath: Halitosis caused by tartar affects daily life. It can be temporarily masked with mouthwash and mint gum, but the real solution is removing the tartar
- Social withdrawal: You may begin to avoid smiling or speaking in close proximity
- Impact on professional life: Hesitation in self-expression in professions involving frequent face-to-face communication (teaching, sales, customer service)
- Loss of self-confidence: Aesthetic problems can create psychological impact
Effects on Systemic Health
Tartar and the chronic periodontal inflammation it causes are linked to systemic diseases. Some of these links are well-established, while others are still being researched:- Cardiovascular disease: Chronic oral infections increase systemic inflammatory burden. Studies show a correlation between periodontal disease and cardiovascular disease; causality is debated
- Diabetes control: This is a bidirectional relationship. Uncontrolled diabetes worsens periodontal disease; periodontal disease can also make blood sugar control more difficult
- Pregnancy complications: Some studies report a link between periodontal disease and preterm birth; however, the strength of this relationship is still under investigation
- Respiratory infections: Bacteria in the mouth can reach the lungs via aspiration and may increase pneumonia risk, especially in bedridden patients
Expansion of Treatment Scope
The later tartar is removed, the more extensive the required intervention:- Early stage: Standard dental scaling is sufficient. Approximately 30-45 minute session
- Mid-stage (significant accumulation): More comprehensive cleaning, sessions divided by regions, polishing
- Gingivitis stage: Cleaning + oral hygiene education + 3-month follow-up
- Periodontitis stage: Curettage (deep cleaning), sometimes periodontal surgery, strict 3-month follow-up
- Advanced periodontitis: Extensive periodontal surgery, bone grafting, extraction of some teeth, implant and prosthetic rehabilitation
How to Prevent It
Tartar is largely preventable. With timely plaque removal and management of risk factors, buildup can be kept to a minimum. However, expecting "zero tartar" is not realistic. Everyone accumulates some. The goal is to keep this accumulation at harmless levels between professional cleanings.Daily Oral Care
- Brush twice daily: Morning and night, at least two minutes each time. Use a soft-bristled brush and fluoride toothpaste
- Correct brushing technique: Hold the brush at a 45-degree angle to the gum line. Use circular or modified Bass motions. Horizontal back-and-forth brushing leaves plaque at the tooth-gum junction
- Floss every day: Clean between teeth at least once daily. These are typically the first places tartar begins. A toothbrush cannot reach these areas without floss
- Interdental brushes or water flossers: For crowded teeth, during orthodontic treatment, or around bridges and implants, these tools provide supplemental cleaning
- Tongue cleaning: Bacterial load that builds up on the back of the tongue indirectly influences plaque formation
- Antibacterial mouthwash: Can help reduce plaque buildup. Alcohol-free formulations are preferred for daily use
Toothpaste Selection
Toothpastes labeled "tartar control" may contain these active ingredients:- Pyrophosphate: Delays plaque mineralization. It does not prevent all tartar but slows it down
- Zinc citrate: Has been shown to reduce plaque accumulation
- Fluoride: Should be in every toothpaste. In addition to preventing cavities, it strengthens enamel
Professional Follow-Up
Diet and Lifestyle
- Limit sugar and starch intake: Frequency matters more than quantity. Eating at set mealtimes rather than snacking all day is better
- Vegetable- and fruit-rich diet: Fibrous foods provide a natural cleaning effect during chewing
- Water consumption: Drinking plenty of water supports saliva production and helps clear bacteria and food debris from your mouth
- Xylitol gum: Chewing xylitol gum briefly after meals increases saliva. Sugary gum has the opposite effect and is not recommended
- Rinse with water after acidic consumption: This quickly returns pH to normal
- Quit smoking: The single most important step in terms of dry mouth, increased tartar staining, and periodontal disease risk
- Control alcohol consumption: Leads to dehydration and reduced saliva
Recommendations for At-Risk Groups
Myths About Removing Tartar at Home
Some home methods circulating online are both ineffective and harmful:- Baking soda and lemon mixture: The acidic effect erodes enamel. It does not dissolve tartar but causes serious erosion
- Rinsing with vinegar: High acidity causes wear
- Scraping with a toothpick or needle: Can seriously damage gums and enamel. Creates infection risk
- Products sold as home "tartar dissolvers": Their effectiveness is unproven, and some contain harmful substances
- Excessively hard brushing: Does not remove tartar but does wear down enamel and cause gum recession
