What is the difference between plaque and tartar?
Plaque is a soft, sticky film of bacteria that forms on your teeth every day. Tartar (also called calculus) is plaque that has hardened and stuck to the tooth surface. Healthdirect describes plaque as a sticky layer of germs on teeth and along the gumline, and explains that if it is not brushed off it can become hard — called calculus or tartar — which can only be removed by a dental professional (healthdirect).
In short:
- Plaque — a soft daily film you can disrupt with brushing and cleaning between the teeth
- Tartar (calculus) — a hardened deposit that home care alone does not clear
This page explains that difference in plain English. It does not retell full brush technique, interdental how-to, or a step-by-step scale and clean visit — those have their own guides. It is general information only, not a personal diagnosis.
Why does plaque matter day to day?
Plaque is constantly forming. Better Health Channel notes that plaque is a sticky coating containing bacteria, and that it is formed when bacteria feed on sugars in foods and drinks (Better Health Channel). Healthdirect explains that bacteria in plaque can release acid that dissolves tooth enamel, and that skipped brushing can lead to calculus (tartar) build-up and gingivitis (healthdirect).
Along the gumline, plaque can irritate the gums. Healthdirect links plaque build-up to gingivitis — red, swollen gums that may bleed when you brush — and notes that untreated gingivitis may progress to more advanced gum disease (healthdirect). The Australian Dental Association likewise describes gingivitis as inflammation where bacteria build up where teeth and gums meet (teeth.org.au).
This is not a scare story about “toxins” circulating through the body. It is everyday mouth biology: soft film left in place can contribute to decay and gum inflammation, and can harden into tartar.
What daily habits help with plaque?
Daily habits aim at the soft film — plaque — before it mineralises:
- Brush twice a day with a soft toothbrush and fluoride toothpaste (about two minutes is a common healthdirect guide)
- Clean between your teeth once a day — floss, interdental brushes, or another tool your dental practitioner recommends
- Spit toothpaste out after brushing; many people skip a water rinse so fluoride stays on the teeth longer
- Limit frequent sugary snacks and sweet drinks between meals, and drink plain water through the day
Healthdirect recommends brushing twice a day and flossing at least once a day, and notes that a toothbrush alone will not reach between the teeth (healthdirect). Better Health Channel likewise advises brushing twice a day along the gumline and cleaning between teeth daily (Better Health Channel).

Why does tartar usually need a dentist or hygienist clean?
Once plaque hardens into tartar, home brushing and flossing do not shift it. Healthdirect states clearly that during a professional clean, dental practitioners use equipment to remove plaque and calculus, and that calculus cannot be removed by brushing at home (healthdirect). Better Health Channel notes that oral health professionals professionally remove plaque and hardened plaque (calculus) as part of gum care (Better Health Channel).
Do not chip or scrape tartar yourself with household tools, metal picks, or DIY scraping kits. That can injure gums and enamel, and it is not a substitute for a professional clean. Tartar removal belongs in the chair.
A scale and clean is the usual way clinics clear hardened deposits and polish the teeth. That companion post covers appointment steps and what you may feel; this page only explains why tartar sits outside what home care can finish.

Common questions
What is plaque?
Plaque is a sticky layer of germs that builds up on teeth and along the gumline. Healthdirect notes that these bacteria feed on food left on the teeth and can release acid that damages enamel. Daily brushing and cleaning between the teeth help disrupt this soft film before it hardens. Ask your dentist at AMK Dental Clinic in Mortlake which routine suits your mouth.
What is tartar (calculus)?
Tartar, also called calculus, is plaque that has hardened on the tooth surface. Healthdirect explains that if plaque is not brushed off, it can become hard and further irritate the gums, and that tartar can only be removed by a dental professional. Home brushing does not clear hardened deposits. A scale and clean at AMK Dental Clinic in Mortlake addresses what builds up beyond home care.
Can I scrape tartar off at home?
No. Do not use household tools, metal scrapers, or DIY kits to chip tartar off your teeth. Healthdirect states that calculus cannot be removed by brushing at home and is cleared with professional equipment. Scraping at home can injure gums and enamel. Book a professional clean at AMK Dental Clinic in Mortlake rather than attempting DIY removal.
What daily habits help reduce plaque?
Brush twice a day with a soft toothbrush and fluoride toothpaste, and clean between your teeth once a day with floss, interdental brushes, or another tool your dental practitioner recommends. Healthdirect advises brushing for about two minutes and flossing at least once a day. Technique guides on this site cover the how-to detail; this page stays on plaque versus tartar. Book AMK Dental Clinic in Mortlake if you want personal advice.
When should I book a scale and clean?
Book if you notice a rough or chalky feel along the gumline, staining that will not brush away, or bleeding gums that continue despite daily cleaning. Healthdirect recommends seeing your dental practitioner every six to twelve months, or as often as they recommend. For what the appointment involves, see our scale and clean guide.
