A cleaning removes something from your teeth that no toothbrush can touch. Here is what actually happens in the chair, why hardened tartar matters, and why the right interval between cleanings is a clinical decision rather than an automatic six months.
What a Professional Cleaning Actually Involves
Most people book a cleaning without much idea of what is about to happen, and the appointment gets folded in with the check-up as one vague hygiene obligation. It is worth separating the two. A check-up is an examination: we look, we ask, we sometimes take an X-ray. A cleaning is a treatment, and it removes something from your teeth that you cannot remove yourself.
At Shuster Dent a cleaning has three parts. First we scale: an ultrasonic tip vibrates hardened deposits off the tooth surface while water rinses them away, and finer hand instruments follow it into the places the ultrasonic cannot reach, including just below the gum line. Then we polish, with a soft rubber cup and a mildly abrasive paste, which lifts surface stain from coffee, tea, red wine and tobacco and leaves the enamel smooth enough that fresh plaque struggles to settle. Finally we clean between the teeth and, where it is useful, apply a fluoride varnish.
Why Your Toothbrush Cannot Do This Part
Plaque is soft, and a careful two minutes twice a day removes most of it. The problem is the plaque you miss. Within a day or two, minerals in saliva harden it into calculus, better known as tartar, which bonds to the tooth rather as limescale bonds to a kettle. No brush, no floss, no mouthwash and no whitening toothpaste will shift it once it has formed. It has to be removed mechanically.
This matters because calculus is not merely unsightly. Its surface is rough and porous, so it holds live bacteria against the gum line all day, which is precisely the condition that keeps gums inflamed. It builds fastest on the inside of the lower front teeth and around the upper molars, where the salivary glands empty.
How Often Do You Actually Need One?
Six months is the interval almost everyone quotes, and for many of our patients it is a sensible default. But it should be a clinical decision rather than a habit. NHS guidance now puts the range between three months and two years depending on risk, and a Cochrane systematic review of routine scale and polish in adults without severe gum disease found that planned six- or twelve-monthly cleanings made little difference to gingivitis or pocket depths over two to three years, beyond a modest reduction in calculus.
We take that evidence seriously, and it does not mean cleanings are pointless. It means the interval should match the person. Someone with healthy gums, no calculus at the last visit and genuinely good home care may not need to come every six months. Someone with a history of periodontitis is in an entirely different category, where regular professional maintenance is among the better-evidenced things we do. Being told you can safely wait a year is a good result, not a brush-off.
Who Should Come More Often
In our experience the patients who benefit from a shorter interval usually have a clear reason for it, and often more than one.
- A history of gum disease, bone loss or gum surgery, where maintenance visits are what keep treated periodontitis stable
- Smoking, which both accelerates gum disease and suppresses the bleeding that would otherwise warn you
- Diabetes, particularly when blood sugar is hard to control, because gum disease and diabetes each make the other worse
- Implants, crowns or bridges, where the gum and bone around the restoration need watching as closely as natural teeth
- Fixed braces, crowded teeth or a persistently dry mouth, all of which make plaque much harder to remove at home
- Fast calculus build-up, which some people simply have because of their saliva chemistry and not because of poor brushing
Will It Hurt, and What Happens Afterwards
For most people a cleaning is uncomfortable rather than painful; it is the vibration and the cold water that patients dislike, not pain. If your gums are already inflamed there will be some soreness and bleeding, because inflamed tissue bleeds when it is touched. That is a sign of the condition being treated, not of rough handling. Tell us if you are sensitive: we can use warmer water, work in shorter sections, or numb the area.
Afterwards the gums may feel tender for a day or two, and teeth can be briefly sensitive to cold where calculus had been covering an exposed root surface. This usually settles within a week, and a sensitivity toothpaste helps in the meantime. If heavy deposits were removed, small spaces may appear between the teeth: the calculus had been filling them, and the gum tightens back over the following weeks as the inflammation resolves.
Making the Cleaning Last
A cleaning resets your mouth; it does not protect it. Plaque begins reforming within hours, and what you do at home over the following months decides whether the next appointment is a quick polish or a long one. Brush twice a day for two minutes with a fluoride toothpaste, clean between the teeth daily, and do not rinse with water straight after brushing: spit, and leave the fluoride where it is.
Tell us what you have noticed, too: gums that bleed, a taste you cannot shift, a tooth that has started catching food. Those details change what we look for.
If it has been more than a year since your last cleaning, or you are not sure when it was, book a visit at our Haifa clinic. We will assess your gums properly and tell you honestly how often you need to be seen, which for some people is less often than they expect.
