Tartar is one of the most common dental concerns, yet many people are unsure of what it actually is or how it differs from plaque. While plaque is something most of us deal with on a daily basis, tartar represents a more advanced stage of buildup that requires professional attention.
Understanding the difference between plaque and tartar — and recognising why tartar cannot be managed at home — is an important step in maintaining good oral health. Early prevention through consistent oral hygiene and routine dental visits remains the most effective approach to reducing tartar buildup and supporting long-term dental wellbeing.
This article explains what tartar is, how it forms, why it requires professional removal, and what you can do to help reduce the likelihood of significant buildup.
Tartar, also known as calculus, is hardened plaque that forms on teeth when plaque is not removed effectively. Once it hardens, it cannot be removed by brushing or flossing alone and requires professional dental cleaning. Regular dental visits help manage tartar buildup and support oral health.
Key Points:
Tartar — referred to clinically as dental calculus — is a hard, mineralised deposit that forms on the surfaces of teeth and along the gum line. It develops when plaque, a soft and sticky bacterial film, is left on the teeth and gradually hardens over time.
Unlike plaque, which can be disrupted and removed through effective brushing and flossing, tartar bonds firmly to the tooth surface. Its rough, porous texture creates an environment that tends to attract further plaque accumulation, potentially compounding the issue over time.
If tartar is not professionally removed, it may contribute to various oral health concerns, including gum irritation and an increased risk of decay.
Understanding how tartar forms can help illustrate why prevention is so important. The process typically follows a predictable pattern:
Poor or inconsistent oral hygiene tends to accelerate tartar formation. Areas that are commonly missed during brushing — such as behind the lower front teeth and around the back molars — are particularly prone to buildup.
While the terms are sometimes used interchangeably, plaque and tartar are quite different:
The critical distinction is that plaque is manageable with good daily oral hygiene, whereas tartar is not. This is precisely why consistent plaque removal through brushing and flossing is so important — once plaque has calcified into tartar, home care alone is insufficient.
One of the most important things to understand about tartar is that it cannot be safely or effectively removed through home oral care. There are several reasons for this:
Brushing and flossing remain essential for removing plaque and helping to prevent new tartar from forming, but they cannot address existing hardened deposits.
When tartar is allowed to accumulate, it may contribute to a range of oral health concerns:
Early and consistent management of tartar through professional cleaning can help reduce these risks.
Tartar removal is carried out through a procedure known as dental scaling. This is a routine part of professional dental cleaning and is typically performed by a dental hygienist or dentist.
During scaling, specialised instruments are used to carefully detach calcified deposits from the tooth surfaces — both above and below the gum line. The two main types of instruments used include:
The procedure is generally well tolerated, though some patients may experience mild sensitivity, particularly if there is significant buildup below the gum line. Your dental professional can discuss comfort options with you before and during the appointment.
It is worth noting that individual results may vary depending on the extent of buildup, overall oral health, and other personal factors.
While it may not be possible to eliminate the risk of tartar formation entirely, consistent oral hygiene practices can significantly help reduce the rate and extent of buildup:
It is important to distinguish between prevention and removal. Good oral hygiene helps prevent tartar from forming, but once it has developed, professional intervention is required to remove it.
Tartar is not always immediately obvious, but there are several signs that may indicate its presence:
If you notice any of these signs, it may be helpful to arrange an assessment with your dental team. Early identification allows for timely management and may help reduce the risk of associated complications.
If tartar buildup is left unaddressed over an extended period, it may contribute to a gradual progression of oral health concerns:
Maintaining a regular schedule of professional cleaning and dental check-ups is one of the most effective ways to help manage tartar and support ongoing oral health.
There are several situations in which it may be appropriate to arrange a dental appointment:
Routine visits to a private dentist allow your dental team to assess your oral health, carry out professional cleaning, and provide personalised advice on maintaining good hygiene habits between appointments.
Consistent, preventive care is generally considered the most effective approach to managing tartar and supporting oral health over the long term.
Tartar is hardened plaque that forms on teeth when plaque is not removed effectively through brushing and flossing. It appears as a yellow or brown deposit, typically along the gum line, and can only be removed through professional dental cleaning.
Tartar cannot be safely removed at home and requires professional dental cleaning. Attempting to remove it using sharp instruments or abrasive products may damage the teeth or gums. Regular brushing and flossing can help prevent plaque from hardening into tartar.
Tartar buildup may contribute to gum irritation and increase the risk of dental problems if left untreated. The rough surface of tartar attracts additional plaque and bacteria, which can lead to gum disease and tooth decay over time.
Tartar can begin forming within days if plaque is not removed regularly. The mineralisation process, during which minerals in saliva harden plaque deposits, can start within 24 to 72 hours of plaque accumulation.
Dentists or hygienists use specialised tools — including ultrasonic scalers and hand instruments — to safely remove tartar during professional cleaning. This procedure, known as scaling, detaches hardened deposits from the tooth surfaces without damaging the underlying enamel.
