Plaque is a soft, sticky bacterial film that forms on your teeth every day. Tartar is what plaque becomes when it is left on your teeth long enough to harden. The key difference is that plaque can be removed at home with proper brushing and flossing, while tartar can only be removed by a dental professional.
Understanding the difference between plaque and tartar matters because both contribute to tooth decay and gum disease, but they require very different treatment approaches. At Pure Smiles in Fulham, our hygienists and dentists treat plaque and tartar buildup daily across our two SW6 practices.
Dental plaque is a soft, colourless-to-pale-yellow biofilm that continuously forms on the surfaces of your teeth, along your gum line and on your tongue. It is made up of bacteria, food particles and saliva. Research has identified approximately 700 species of bacteria that can live in the human mouth, and when these organisms combine, they form a biofilm that clings to tooth surfaces and becomes harder to dislodge over time.
Plaque is not a sign of poor hygiene on its own. Everyone develops plaque, even people who brush and floss regularly. What matters is how quickly and effectively you remove it.
Plaque begins forming within hours of brushing. When you eat or drink anything containing sugars or starches, the bacteria in plaque feed on those sugars and produce acids. Those acids attack your tooth enamel, which is how cavities form. If plaque is allowed to remain along the gum line, it irritates the gum tissue and can lead to the early stages of learn more gum disease.
Plaque is not the same as tartar. Plaque is soft and removable at home. Tartar is hard and requires professional removal.
Tartar, also known as dental calculus, is hardened plaque. When plaque remains on your teeth for more than 24 to 72 hours, it begins to mineralise by absorbing calcium and phosphate from your saliva. Once this hardening process is complete, the deposit can no longer be removed with a toothbrush or floss.
Tartar forms most commonly on the lower front teeth (behind the bottom incisors) and on the outer surfaces of the upper molars, because these areas are closest to the salivary glands. It can appear as a yellowish or brownish rough deposit along the gum line or between teeth.
Tartar is a serious concern because it creates a rough surface that attracts even more plaque, creating a cycle of buildup that accelerates damage to your teeth and gums. It also makes it significantly harder to keep your teeth clean, since brushing and flossing cannot reach the tooth surface beneath the calcified deposit. Left untreated, tartar leads to gingivitis and eventually learn more periodontitis, which can result in tooth loss.
| Feature | Plaque | Tartar |
|---|---|---|
| **What it is** | Soft bacterial biofilm | Hardened, mineralised plaque |
| **Colour** | Colourless to pale yellow | Yellow, brown or dark |
| **Texture** | Soft, sticky, slimy | Hard, rough, calcified |
| **Formation time** | Forms within hours of brushing | Develops when plaque sits for 24-72 hours |
| **Removable at home** | Yes, with brushing and flossing | No, requires professional cleaning |
| **Treatment** | Daily oral hygiene routine | Scaling and polishing by a dentist or hygienist |
| **Risk if untreated** | Cavities, early gum disease | Periodontitis, tooth loss, receding gums |
| **Common locations** | All tooth surfaces and gum line | Behind lower front teeth, outer upper molars |
The single most important distinction is removability. Plaque is preventable and treatable at home. Tartar is not.
Plaque removal is something you can and should manage yourself every day. Effective daily oral hygiene is the best defence against both plaque buildup and the tartar that follows.
Brushing. Brush your teeth at least twice a day for two minutes each time, using a fluoride toothpaste. An electric toothbrush with a round oscillating head is more effective at disrupting plaque biofilm than a manual brush. Pay particular attention to the gum line and the backs of your teeth.
Flossing. Floss at least once a day to remove plaque from between your teeth and below the gum line, where bristles cannot reach. Interdental brushes are a good alternative if you find flossing difficult.
Mouthwash. An antibacterial mouthwash can help reduce bacterial load in your mouth, but it is not a replacement for brushing and flossing. Use it as an addition to your routine, not a substitute.
Diet. Reducing your intake of sugary and starchy foods limits the fuel that plaque bacteria feed on. Drinking water after meals helps rinse away food particles.
If you are unsure whether your daily routine is effective enough, booking a learn more hygiene appointment at Pure Smiles gives you personalised guidance on technique and frequency.
Tartar cannot be removed at home. Attempting to scrape it off yourself risks damaging your tooth enamel or injuring your gums. Professional removal is the only safe and effective option.
The most common tartar treatment is a professional scale and polish performed by a dentist or dental hygienist. Scaling involves using specialised instruments, either manual hand scalers or an ultrasonic scaler, to carefully remove calcified deposits from above and below the gum line. The teeth are then polished to smooth the enamel surface, making it harder for new plaque to stick.
At Pure Smiles, a routine scale and polish typically takes 30 to 45 minutes and is recommended at least every six months, or more frequently if you are prone to tartar buildup.
If tartar has extended below the gum line and caused pockets to form between your teeth and gums, your dentist may recommend scaling and root planing. This is a more thorough procedure that cleans the root surfaces of your teeth and smooths them to help your gums reattach. It is typically carried out under local anaesthetic and may require more than one appointment.
Scaling and root planing is not the same as a standard clean. It is a treatment for active gum disease and is only necessary when the condition has progressed beyond what a routine scale and polish can address.
You should book an appointment if you notice any of the following:
Early intervention prevents minor plaque issues from becoming serious tartar problems. Regular dental check-ups and hygiene appointments are the most effective way to stay ahead of buildup.
Pure Smiles has been providing preventive dental care in Fulham since 2009. As a family-run practice, we take time to understand each patient’s oral health habits and tailor hygiene advice to their specific needs.
Dr Ayzaaz Akram (BDS University of Liverpool 1995, GDC 70996) leads our team, and our dental hygienists work closely with patients to address plaque and tartar concerns before they develop into more serious conditions.

Plaque is a soft, sticky bacterial film that forms on your teeth daily and can be removed by brushing and flossing. Tartar is hardened plaque that has mineralised on the tooth surface and can only be removed by a dental professional using scaling instruments. The main difference is that plaque is manageable at home, while tartar is not.
No. Tartar cannot be safely removed at home. It is a calcified deposit bonded to the tooth surface, and attempting to scrape it off with household tools or sharp objects can damage your enamel and injure your gums. Only a dentist or dental hygienist has the instruments and training to remove tartar without causing harm.
Plaque can begin hardening into tartar within 24 to 72 hours if it is not removed. This is why brushing twice daily and flossing at least once a day is essential. Once tartar has formed, no amount of brushing will remove it.
Most patients benefit from a professional scale and polish every six months. If you are prone to heavy tartar buildup, have a history of gum disease or wear braces, your dentist may recommend more frequent visits, typically every three to four months. At Pure Smiles in Fulham, we assess each patient individually and recommend a schedule that suits their needs.
Yes. Tartar is one of the primary contributors to gum disease. It creates a rough surface that harbours bacteria, and when it sits along or below the gum line, it causes inflammation, bleeding and eventually the breakdown of the bone and tissue supporting your teeth. Removing tartar through regular professional cleaning is one of the most effective ways to prevent gum disease from developing or progressing.
