Professional tooth cleaning
What the practice removes, where the brush at home cannot reach.
Dental plaque is not dirt but a living layer of bacteria. As long as it is soft, it can be brushed away. After about one to two days it begins to take up minerals from the saliva and harden. What has then formed is called tartar, and no brush and no paste removes it any more. That is exactly where professional tooth cleaning starts.
It is not a treatment in the narrower sense — nothing is drilled and nothing is replaced. It is a thorough cleaning by trained staff, usually a dental assistant with further training in prevention or a dental hygienist, and depending on the findings it takes between half an hour and a full hour.
What is actually removed
Three things come off that are left behind at home:
- Tartar above the gum line, above all on the inner surfaces of the lower incisors and the outer surfaces of the upper molars — where the salivary glands open.
- Deposits below the gum line, in the narrow groove between tooth and gum. They are the actual cause of gum inflammation, and no brush reaches there.
- Discolouration from coffee, tea, red wine and tobacco. It is cosmetic, but its rough surface gives new plaque extra hold.
At the end the teeth are polished. A smooth surface is harder to colonise than a rough one — which is why the polishing is not an extra but the reason the cleaning lasts a while.
What it does not achieve
Professional tooth cleaning does not bleach the teeth. It takes off deposited discolouration so that the tooth's own colour becomes visible again — the tooth does not become lighter than that. Anyone who wants a different colour is talking about bleaching, and that is a separate decision with its own requirements.
Nor does it replace brushing. The biofilm begins to build up again within a few hours. A cleaning in spring does not rescue a year in which the interdental spaces remain untouched. The benefit arises from the combination: regular cleaning at the practice plus daily oral hygiene at home.
And it does not cure periodontitis. Where bone loss is advanced, systematic periodontal treatment is needed; the cleaning is then preparation and follow-up care, not the therapy.
Who benefits most from it
In young adults with healthy gums and careful oral hygiene the measurable gain is modest. It is considerably greater if one of these points applies:
- The gums bleed when brushing, or they are reddened and swollen.
- There are implants, bridges, crowns or removable dentures. Margins and transitions are places where plaque holds on stubbornly.
- Periodontal treatment lies in the past. The cleaning is then part of the structured follow-up care.
- There is diabetes, an immune deficiency or a pregnancy — situations in which the gums react more sensitively.
- A fixed brace makes brushing considerably harder.
- The amount of saliva is reduced, for instance as a side effect of medication.
The appointments are no substitute for the check-up
Cleaning and check-up are two different things, even if they often take place on the same day. The check-up looks for caries, examines fillings and dentures and records the gum findings. The cleaning then starts from what the findings have shown. Anyone who comes only for the cleaning leaves out the more important part.
The essentials at a glance
- Professional tooth cleaning removes tartar and deposits below the gum line — a toothbrush no longer gets either of them off.
- It does not replace brushing at home. The plaque is back after a few hours; the cleaning merely sets the starting point anew.
- The benefit is greatest with inflamed gums, with implants and dentures, and after periodontal treatment.
- How often it is needed depends on the findings, not on the calendar. For healthy adults, one or two appointments a year is the usual range.
