Most people know they should brush and floss regularly, but fewer understand what happens when plaque is missed consistently, and why the resulting build-up can’t simply be brushed away once it forms. Tartar, also known as calculus, is hardened plaque that bonds to tooth surfaces and can only be removed by a dental professional. Left unchecked, it sets off a chain of events that progresses from mild gum irritation to serious, irreversible damage.
This guide explains what tartar is, how it forms, what it does to your gum health and teeth over time, how it’s professionally removed, and what you can do at home to slow its formation significantly.
What Is Tartar and How Does It Form?
Plaque is a soft, sticky film of bacteria that forms on teeth continuously throughout the day. It’s colourless, adheres to all tooth surfaces, and is removed effectively by brushing and flossing. This is why twice-daily brushing and daily flossing remain the foundation of oral hygiene.
The problem begins when plaque is not consistently removed. Within 24 to 72 hours, mineral ions from saliva begin to deposit into the plaque film, gradually hardening it into a calcified structure. This is tartar. Unlike plaque, tartar cannot be brushed or flossed away once it has formed. It bonds firmly to the tooth surface and, critically, to any roughness or irregularity on that surface, including the rough texture of tartar itself.
Tartar typically appears as a yellowish or brownish deposit, most visibly on the inner surfaces of the lower front teeth and the outer surfaces of the upper molars, where salivary ducts are closest. It forms both above the gum line, where it is visible, and below the gum line, where it is not and where its consequences are more serious.
The Risks of Tartar Build-Up
Tartar itself is not the direct cause of tooth decay or gum disease. The problem is what it enables. Its rough, porous surface acts as a highly effective scaffold for further plaque accumulation, harbouring bacteria in a structure that is shielded from brushing. This sustained bacterial presence, particularly below the gum line, is where the damage begins.
Gingivitis
The first response of the gum tissue to bacterial accumulation from tartar is inflammation. Gums become red, swollen, and bleed easily during brushing or flossing. This is gingivitis, the earliest stage of gum disease. It is reversible: with professional tartar removal and gum disease treatment combined with improved home hygiene, the inflammation resolves and the gum tissue returns to health. Bleeding gums when brushing are among the early warning signs that gum disease may be developing, and addressing them at this stage is far simpler than managing what follows if they’re left.
Periodontitis
If tartar is not removed and gingivitis goes unaddressed, the inflammation progresses into the deeper supporting structures of the tooth. This is periodontitis, a chronic condition that damages the soft tissue and bone holding the teeth in place. The signs that gum disease has advanced beyond gingivitis include gum recession, tooth sensitivity from exposed roots, loosening teeth, persistent bad breath, and the development of deep periodontal pockets. Unlike gingivitis, the bone and tissue destruction caused by periodontitis is not fully reversible. Gum disease care at this stage focuses on halting further progression and managing the condition long term.
Bone Loss and Tooth Loss
As periodontitis advances, the bone that supports tooth roots is progressively destroyed by the body’s inflammatory response to bacterial toxins. Teeth that lose sufficient bone support become mobile and may eventually be lost. Tooth loss from advanced gum disease is one of the leading drivers of adults needing dental implants to restore function and prevent further bone resorption.
Cavities and Decay
The bacterial environment created by tartar also increases the risk of tooth decay. Acid-producing bacteria in tartar deposits erode enamel progressively. Where early decay is caught before it becomes significant, a dental filling is all that’s needed. Once decay has reached the pulp, the options become more complex and costly. Regular tartar removal is one of the most effective ways to keep decay risk manageable.
Bad Breath
Bacteria in tartar deposits and the infected pockets they help create produce volatile sulphur compounds, the primary driver of persistent bad breath. Mouthwash addresses the symptom temporarily but cannot reach the bacterial source embedded in tartar and below the gum line. Professional removal addresses the cause.
Systemic Health Links
There is substantial research establishing a connection between chronic gum disease and systemic health conditions including cardiovascular disease, type 2 diabetes, and adverse pregnancy outcomes. According to the Australian Dental Association, gum disease is one of the most common chronic conditions in Australia and is significantly underdiagnosed because early stages are often painless.
Professional Tartar Removal: What the Process Involves
Once tartar has formed, professional removal is the only option. Home tools are designed for plaque, and attempting to scrape tartar at home risks scratching enamel and damaging gum tissue. Professional scaling uses instruments calibrated for the hardness and depth of tartar deposits without harming surrounding structures.
The Scale and Clean Process
Examination. Your dentist or hygienist begins by assessing the extent and location of tartar deposits, including probing for pocket depth between teeth and gums.
Scaling. Tartar is removed using hand scalers, thin hooked instruments that scrape deposits from the tooth surface, or ultrasonic scalers, which use high-frequency vibration combined with a water stream to break down and flush away calculus. Ultrasonic scaling is typically more comfortable for larger or deeper deposits. Both above and below the gum line are treated.
Root planing. Where tartar has extended below the gum line and periodontitis is present, root planing smooths the root surfaces after scaling to remove bacterial toxins and discourage further attachment. This may be done in stages across multiple appointments for more advanced cases.
Polishing. Following scaling, tooth surfaces are polished with a mildly abrasive paste and a rotating cup. This removes surface staining and leaves a smooth surface more resistant to rapid plaque re-adhesion. Patients whose teeth have accumulated staining alongside tartar often notice a visible improvement in brightness after polishing, though this is distinct from cosmetic teeth whitening treatment, which addresses deeper discolouration.
Flossing and review. Interdental cleaning completes the appointment. Your clinician will also review your home care technique and recommend any adjustments.
How Often Should Tartar Removal Be Scheduled?
For most patients with healthy gums and a consistent home care routine, professional cleaning every six months is the standard recommendation. This interval allows tartar to be removed before it contributes to gum inflammation.
Some patients benefit from more frequent appointments, typically every three to four months. This applies to those with:
- History of gum disease or periodontitis
- Diabetes, which has a well-established bidirectional relationship with gum health
- Current orthodontic treatment. Invisalign aligners and fixed braces both create additional surfaces where plaque accumulates more readily, making consistent professional monitoring particularly important
- High tartar formation rates
- Smoking, which impairs the immune response and significantly increases susceptibility to gum disease
Your dentist will determine the most appropriate recall interval based on your clinical assessment rather than a generic schedule.
Preventing Tartar Build-Up at Home
Professional cleaning removes what has already formed. Daily home care is what determines how quickly tartar returns between appointments. The goal is to remove plaque consistently before it can mineralise.
Brush twice daily. Use a soft-bristled toothbrush for two minutes, covering all tooth surfaces and the gum line. An electric toothbrush with a pressure sensor is more effective at plaque removal for most people.
Floss once daily. Plaque between teeth and at the gum margin is inaccessible to a toothbrush. Flossing is the only reliable way to remove it from these surfaces. Skipping it consistently is one of the primary reasons interproximal tartar accumulates.
Use fluoride toothpaste. Fluoride strengthens enamel and makes the tooth surface more resistant to the acid attacks produced by plaque bacteria.
Consider an antimicrobial mouthwash. Used as a complement to, not a replacement for, mechanical cleaning, an antimicrobial rinse helps reduce the bacterial load in the mouth between brushing sessions.
Limit fermentable carbohydrates. Sugary and starchy foods provide the substrate for acid-producing bacteria. Frequency of exposure matters as much as quantity, so grazing throughout the day increases risk more than the same amount consumed at a single meal.
Stay hydrated. Saliva has natural antibacterial and buffering properties. Chronic dehydration or dry mouth significantly increases plaque formation and tartar risk.
Avoid tobacco. Smoking and smokeless tobacco both significantly accelerate tartar formation and gum disease progression. Nicotine restricts blood flow to gum tissue, masking bleeding that would otherwise signal early disease.
A Note on Home Tartar Removal Products
Various products, including dental picks, tartar scraping tools, and abrasive home scaling kits, are marketed directly to consumers. These carry real risks. Tooth enamel can be scratched by improper technique, and gum tissue can be lacerated. Tartar below the gum line is entirely inaccessible to home instruments without causing harm.
Products like interdental brushes and water flossers are valuable additions to home care for plaque removal, but they are not substitutes for professional scaling. Once plaque has hardened into tartar, a dental professional is the only safe and effective option.
