Most adults should have a professional cleaning every six months. Smokers, people with diabetes, orthodontic patients and anyone with a history of gum disease usually need it every three to four months. Scaling does not loosen or damage teeth — it removes the tartar that was splinting teeth already loosened by bone loss, which is why they can feel different afterwards.
Where 'every six months' comes from
Six months is a reasonable population-level default rather than a biological law. The sensible approach is to set the interval by your actual risk, which is why we re-assess it at each visit rather than booking everyone into the same rhythm.
Who needs cleaning more often
- Smokers and tobacco users — faster tartar build-up and masked bleeding.
- People with diabetes, where gum disease and blood sugar worsen each other.
- Anyone with a history of periodontitis, where the risk of recurrence is permanent.
- Orthodontic patients — brackets make thorough cleaning genuinely difficult.
- Those with crowded teeth or many restorations with hard-to-clean margins.
- Pregnant women, whose gums respond more strongly to the same amount of plaque.
The myth that scaling loosens teeth
This is the most persistent belief we encounter, and it deserves a direct answer. Ultrasonic scaling removes calcified deposits; it does not remove enamel and it does not loosen healthy teeth.
What actually happens in advanced gum disease is that heavy tartar bridges the gaps between teeth and acts as a splint, holding together teeth that have already lost bone support. Remove the tartar and the mobility that was always there becomes noticeable. The scaling revealed the problem; it did not cause it. Leaving the tartar would have accelerated the bone loss underneath.
What a cleaning appointment includes
- Gum chartingPocket depths measured around each tooth, so the disease is graded rather than guessed.
- Ultrasonic scalingTartar removed from above and below the gum line.
- PolishingSurface stain removed and the tooth surface smoothed, which slows re-accumulation.
- Technique reviewThe specific areas you are missing, shown to you — usually the same ones every time.
Between appointments
Professional cleaning removes what has already hardened. It does not substitute for daily cleaning, and a six-monthly appointment cannot compensate for six months of missing the same surfaces. Brushing twice daily for two minutes with a soft brush, plus cleaning between the teeth once a day, is what determines whether your next appointment is short and routine.
Questions we get asked
Does scaling create gaps between teeth?
The gaps were already there, filled by tartar and swollen gum tissue. As the gum heals it shrinks to its healthy contour and the spaces become visible. This is recovery from disease, not a side effect of the cleaning.
Is ultrasonic scaling painful?
Usually not. It can be sensitive where roots are exposed or gums are severely inflamed, and local anaesthesia can be used for deeper cleaning below the gum line.
Can I just clean well at home instead?
Excellent home care greatly reduces how much builds up, but no amount of brushing removes tartar once it has hardened, and nothing at home reaches below the gum line. The two are complementary, not alternatives.
