How to Clean Teeth Tartar Safely and Effectively

You cannot remove hardened tartar at home. Once plaque mineralises, it is chemically bonded to the tooth — a brush, floss, mouthwash or a home scraper will not shift it, and trying can injure the gum. Removing it takes an ultrasonic scaler and hand instruments, which means a dentist or hygienist. What you can do at home is stop the next lot forming, and that part is entirely in your hands.

This guide covers why brushing can’t do it, what the professional removal actually involves instrument by instrument, what happens below the gum line, and how to keep it from coming straight back.

Tartar — clinically, dental calculus — is plaque that has hardened. Plaque itself is a soft, sticky film of bacteria that reforms on your teeth within hours of brushing. Left in place, minerals in your saliva crystallise inside it, and within a few days the soft film becomes a hard deposit locked onto the enamel.

That is the whole difference, and it explains everything else about the problem:

It collects where a brush struggles: along the gum line, between teeth, and classically behind the lower front teeth, where a salivary duct opens directly onto them. Its surface is porous and rough, so it holds pigment from coffee, tea and tobacco — which is why it is often noticed as discolouration first. That overlap is covered in our guide to brown stains on teeth.

Being rough, it also gives fresh plaque more to grip. Tartar accumulates faster once there is already tartar there.

No. And the reason is worth understanding, because it is not about effort.

Plaque is on the tooth; a brush wipes it away. Calculus is mineralised onto the tooth, mechanically interlocked with the enamel surface. Bristles cannot generate the force to fracture that bond, and neither can floss or any mouthwash. Brushing harder does not change the physics — it just wears enamel and irritates the gum margin.

So brushing remains essential, but for a specific job:

• Brushing and interdental cleaning prevent plaque from mineralising in the first place.
• Neither removes calculus once it has formed.

The NHS is clear on where this leads if it is left: gum disease is caused by plaque building up and irritating the gums, and in the early stages the advice is cleaning between the teeth daily and having the teeth cleaned by a hygienist.¹ That is a small intervention, and it is the whole reason not to leave it.

The procedure is called scaling, and it uses two instruments that do different jobs.

• An ultrasonic scaler. The tip vibrates at high frequency and fractures the deposit off the tooth rather than scraping it, while a water spray cools the tip and washes the debris away. This does the bulk of the work, and it is where the buzzing and the water come from.
• Hand instruments (curettes and scalers). Fine hand tools finish the job by feel, reaching the areas the ultrasonic tip cannot follow — under the gum margin and around the curve where two teeth meet.
• Polishing. A rubber cup and paste smooth the surface afterwards, which removes remaining surface stain and leaves less for plaque to grip.

For deposits above the gum line — supragingival calculus — this is a single routine appointment, and no anaesthetic is normally needed. If you want the distinction between this and a cosmetic treatment, our comparison of teeth cleaning vs teeth whitening sets it out: cleaning removes what is on the tooth, whitening changes the colour of the tooth itself.

Where deposits have formed on the root surface inside the gum pocket, a routine clean cannot reach them, and the treatment is scaling and root planing — often described to patients as a deep clean. The root surface is cleaned and smoothed inside the pocket, usually with local anaesthetic and often across two appointments.

This is well-supported ground rather than an upsell. The ADA’s clinical practice guideline on the nonsurgical treatment of chronic periodontitis found that scaling and root planing showed a moderate benefit, that the benefits outweighed the potential adverse effects, and the panel voted in favour of it as the initial nonsurgical treatment.³

One detail from the same guideline is worth carrying into any consultation, because laser gum treatment is offered widely: the panel’s recommendations for the nonsurgical use of lasers as adjuncts to scaling and root planing were expert opinion against, because of uncertainty about their clinical benefit and the balance of benefit to adverse effects.³ A laser is not a substitute for the instrument work.

What the procedure involves step by step is covered in our guide to scaling and root planing.

Teeth feel noticeably smoother, and most people find the colour improves without any whitening — because a good share of what they were seeing was the deposit rather than the tooth.

Two things surprise people, and both are normal:

• Some bleeding during and just after. Gums bleed where they were already inflamed, not because the cleaning caused it. It settles as the inflammation resolves over the following days.
• Short-term sensitivity to cold. Root surface that was covered by the deposit is now exposed to the mouth. It typically settles within a couple of weeks, and a desensitising toothpaste helps in the meantime.

Because tartar has to be professionally removed once it forms, everything useful you can do is on the prevention side — and there it works well.

• Clean between your teeth every day, with floss or interdental brushes. The NHS lists this alongside brushing, not as an optional extra¹ — and between the teeth is precisely where tartar starts.
• Brush twice daily with fluoride toothpaste, angled into the gum line rather than straight at the tooth. Spit, don’t rinse.
• Pay attention to the inside of the lower front teeth, the single most common site and the one most often missed.
• Address a dry mouth. Reduced saliva changes how quickly deposits build. If a medication is the cause, it is worth raising rather than living with.
• Stop smoking, which increases build-up and is the strongest modifiable factor in gum health generally — the same one that shows up in our guide to why implants fail.
• Keep the recall interval you were given. Not everyone needs the same one; it is set from how fast you personally build deposits.

Very few people fly abroad for a scale and polish alone, and it would be odd to suggest otherwise. Where this matters for international patients is different: a hygiene appointment is the step that comes before cosmetic or implant work, not after it.

Veneers, crowns and implants all depend on healthy gum tissue. Ceramic margins sit at the gum line, and inflamed, bleeding gums make an accurate impression and a clean bond harder to achieve. So when a treatment plan is built at DentSpa, the gum condition is assessed at the examination and cleaning is scheduled first if it is needed — which is why you may see it in your plan when you came for something else entirely.

The examination establishes how much deposit there is, where it sits relative to the gum, whether pockets have formed, and whether anything needs treating before the cosmetic work starts. Where the gum margin itself is uneven once the tissue is healthy, that is a separate conversation — see gum contouring. And if decay has been sitting under a heavy deposit, our guide to fixing tooth decay covers what happens next.
