Why a Clean Is Not Optional
Brushing and flossing remove plaque while it is soft. What they cannot remove is plaque that has already hardened.
Tartar can only be taken off with instruments. No toothpaste, mouthwash or brushing technique will shift it.
That is the whole reason this appointment exists. Everything else about it is secondary.
How Tartar Forms
Plaque is a soft film of bacteria that rebuilds within hours of brushing. Left in place, it absorbs minerals from your saliva.
Within a day or two it begins to harden. Within a couple of weeks it is firmly bonded to the tooth.
It builds fastest where saliva enters the mouth. That means behind the lower front teeth and on the outside of the upper back teeth.
Those are exactly the spots most people rush. If you have ever felt a rough ledge behind your bottom front teeth, that is tartar.
What the Appointment Removes
- Hardened tartar above the gum line.
- Tartar just below the gum margin, where a brush cannot reach.
- Surface stain from tea, coffee, red wine and smoking.
- Plaque from the spots you consistently miss.
If tartar has gone deeper and pockets have formed, a routine clean is no longer the right treatment. That needs root planing under anaesthetic.
Your dentist decides which of the two you need by measuring the gums first.
What It Feels Like
The ultrasonic scaler vibrates at high speed and sprays water. It is noisy, and the water is cold, but it is not cutting anything.
Discomfort comes from inflamed gums, not from the instrument. Gums that are healthy barely register the clean.
This produces an unfair pattern. The longer you leave it, the more uncomfortable it is, which makes people leave it longer still.
Coming regularly is what breaks that cycle. Tell your dentist if you find it painful, because numbing gel can be used.
Bad Breath
Persistent bad breath usually comes from bacteria, not from what you ate. Tartar and inflamed gums both hold those bacteria.
Mouthwash covers the smell for an hour or two. Removing the deposits addresses the source.
The tongue is the other common source, and brushing it is worth adding to your routine.
The Polish and the Fluoride
Once the deposits are off, the teeth are polished smooth and fluoride is applied. Both steps come at the end of the same visit.
Those two steps have their own page. See polishing and fluoride for what each one does and who benefits most.
How Often You Need One
Six months suits most people, alongside the check-up. It is a starting interval, not a fixed rule.
- Smokers, who build stain and tartar faster.
- Anyone treated for gum disease, usually every three or four months.
- Patients wearing braces.
- People with a dry mouth, often from medication.
- Anyone who builds tartar quickly, which is partly down to saliva chemistry.
Some people build tartar heavily however well they brush. That is not a failure of effort, and it simply means shorter intervals.
Keeping It Clean Between Visits
- Brush twice a day for two full minutes.
- Angle the brush towards the gum line, which is where tartar starts.
- Clean between the teeth daily with floss or interdental brushes.
- Spend extra time behind the lower front teeth.
- Spit out toothpaste and do not rinse.
Cleaning between the teeth matters more than brushing harder. Hard brushing wears enamel and pushes gums back without cleaning the gaps.
Stain a Clean Will Not Remove
A clean removes stain sitting on the surface. It does not change the natural colour of the tooth underneath.
If your teeth still look yellow after a clean, that colour is inside the enamel. Only whitening reaches it.
It is worth having the clean first either way. You then know how much of the colour was stain and how much was the tooth.
Children
Children build less tartar than adults, so their visits focus on plaque, brushing technique and fluoride.
It is also where sealants are checked, since they wear gradually and are topped up as needed.
Bringing a child regularly from a young age matters as much as the clean itself. They learn that a visit is routine rather than something to dread.
