The short answer
The main part of periodontitis (Parodontitis) treatment — cleaning the root surfaces below the gum line — is carried out under local anaesthetic (Betäubung), and most patients describe it afterwards as pressure, vibration and a lot of water rather than pain. The moments people actually report as uncomfortable are smaller and earlier than they expect: the measuring probe touching an inflamed spot, and the injection itself, which is usually preceded by a numbing gel. The days after treatment tend to bring tenderness and cold sensitivity rather than sharp pain, and most people go back to work the same day or the next. No dentist can promise you will feel nothing — sensitivity varies from person to person — but the level of discomfort in this treatment is one of the most consistently overestimated things in dentistry.
Why people expect it to hurt
Two reasons, and both are worth naming.
The first is the vocabulary. Terms like “deep cleaning”, “root planing” and “scaling below the gum line” sound surgical. In German, the word Kürettage sounds worse still. The procedure is thorough, but the mental image most people build from the words is considerably more dramatic than the reality.
The second is that the gum already hurts before anything is done. Inflamed tissue is tender to touch. Patients reasonably assume that if a probe hurts, instruments must hurt far more. In fact the opposite applies once anaesthetic is on board: the inflamed tissue stops reporting anything at all.
There is also a memory factor. Anyone whose last thorough scaling happened years ago, without anaesthetic, on gums that were already inflamed, has a genuinely unpleasant reference point. That is not how a modern periodontal appointment is run.
Stage by stage: what you actually feel
The measuring appointment
A graduated probe is walked around each tooth at six points. On healthy sites you feel a light touch, nothing more. On inflamed sites you may feel a brief sting, and those sites usually bleed — which is diagnostic information rather than a sign of injury.
This is typically the most uncomfortable appointment of the whole course, and it lasts a few seconds per tooth. No anaesthetic is normally used. If your gums are extremely tender, say so and a topical gel can be applied first.
The hygiene appointment before the treatment phase
Tartar (Zahnstein) is removed from above the gum line, usually with an ultrasonic scaler and a water spray. Sensations: vibration, a high-pitched sound, cold water, and occasionally a short zing on an exposed root neck. Rarely painful; frequently described as “odd but fine”. If cold sensitivity bothers you, the water temperature and the instrument settings can be adjusted, and this is worth mentioning at the start rather than enduring.
The injection
For most anxious patients, this is the moment the whole appointment is really about.
What happens: a numbing gel goes onto the gum first and is left to work for a minute or two, so the needle enters tissue that is already partly numb. The injection is then given slowly — the speed matters more than anything else, because most of the sensation people remember comes from fluid being delivered too fast, not from the needle. What you typically feel is a light pressure and a spreading warmth. Some people feel a brief pinch; some feel nothing at all.
Within a few minutes the lip, cheek or tongue on that side feels thick and unfamiliar. That numbness is the strangest part of the appointment for most patients, and it wears off over a couple of hours.
If needles are a serious problem for you, say so before you sit down. Options exist, including sedation and laughing gas (Lachgas), and they are used precisely for this.
The deep cleaning itself
This is the part that treats the disease: the biofilm and hardened deposits are removed from the root surfaces inside the pocket, with ultrasonic tips and fine hand instruments.
Under working anaesthetic, patients report: pressure at the gum, vibration, scraping sounds transmitted through the jaw bone, water, and the suction. Not pain. The typical feedback afterwards is that the sound was more memorable than the sensation.
The appointment usually covers half the mouth or one quadrant at a time, so one side stays functional. Expect to be in the chair a while — this is careful work and it is not rushed. Bring headphones if sound bothers you; most people find music the single most effective comfort measure available.
If you do feel something sharp, raise your hand. Anaesthetic occasionally does not reach a particular root, or wears off sooner in one area. Topping it up takes a minute. There is no medal for enduring it, and telling us is not an interruption — it is information we need.
The re-assessment and the aftercare appointments
The re-assessment is a measuring appointment again, and the notable thing is that it usually hurts less than the first one, because inflamed tissue that has healed no longer stings when probed. Patients often mention this unprompted; it is a good, tangible sign of progress.
The aftercare appointments — supportive periodontal therapy (unterstützende Parodontitistherapie, UPT) — are cleaning sessions at fixed intervals. Most are done without anaesthetic. Where an individual pocket remains deep and needs instrumenting again, local anaesthetic is used for that site.
The days afterwards: what is normal
Day of treatment. The numbness lasts roughly two to three hours. Do not chew until it has fully gone — biting a numb lip or cheek is the most common self-inflicted injury after any dental appointment. Choose something soft and lukewarm for the first meal.
Days one to three. Gums feel bruised or tender, particularly when brushing. Some oozing of blood in the first hours is normal; heavy bleeding is not. Teeth commonly become sensitive to cold — this is expected, because root surfaces that had been buried under deposits are now exposed and clean.
The first two weeks. Sensitivity usually fades gradually. A desensitising toothpaste helps most people; a fluoride varnish can be applied in the practice if it does not.
The visible change. As swelling subsides, gums shrink back slightly. Teeth may look longer, and small gaps can appear between them. This looks like deterioration and is in fact healing: the tissue is now firm rather than puffy. It is worth being told this in advance, because otherwise it is alarming.
Pain relief. Most patients need nothing, or one dose of an ordinary over-the-counter painkiller on the first evening. Ask us which one suits you before taking anything, since some — for instance those containing acetylsalicylic acid — increase bleeding and are a poor choice straight after this treatment. If you take anticoagulant medication, tell us before the appointment rather than after it.
When to contact us afterwards
None of these are common. All of them are reasons to phone rather than to wait and see.
If you are an anxious patient
Fear of pain is the most frequent reason gum disease reaches an advanced stage before anyone looks at it — which is a difficult irony, because the advanced stage is what makes treatment longer.
What genuinely helps:
- Say it at the booking. “I’m anxious” changes the appointment before it starts: a longer slot, more explanation, no rush.
- Come for the examination first. An examination involves no drilling, no injection and no commitment. Many people find that the appointment they dreaded consisted of looking, measuring and talking.
- Agree a stop signal. A raised hand means we stop immediately, not at a convenient point. Knowing you can stop is often what makes stopping unnecessary.
- Ask for narration or for silence — whichever you prefer. Some people are calmed by being told each step in advance; others want music and no commentary.
- Sedation and laughing gas (Lachgas) are available in our practice for exactly these situations. Laughing gas takes the edge off while you stay awake and responsive, and it clears from your system quickly afterwards.
Where ozone fits in
Ozone treatment is one of the supportive options we offer alongside periodontal treatment. Ozone has an antimicrobial effect and can be applied to a pocket after it has been mechanically cleaned, with the aim of reducing the remaining bacterial load. It is painless in itself and involves no additional injection.
The important framing, and we would rather be plain about it: ozone is an adjunct, never a replacement. It does not remove a biofilm from a root surface, and no ozone application substitutes for the mechanical cleaning that is the core of the treatment. It is offered where it may support the outcome in an individual case, and we will tell you honestly when we think it adds nothing. Ozone therapy – service page (EN)
What it costs you in comfort versus what it costs you in money
Briefly, because it is the second question everyone asks. Periodontitis treatment is a benefit of statutory health insurance (gesetzliche Krankenversicherung, GKV), but it runs on its own approved plan: your dentist submits a periodontal treatment plan (PAR-Behandlungsplan) to your fund after the full measurement, the fund approves it, and only then does the treatment phase begin. The approved course covers the stages described above, including the aftercare appointments over a defined period. Certain additional or supportive measures — for example a professional cleaning (professionelle Zahnreinigung, PZR), laser or ozone applications, or particular sedation options — sit outside that catalogue and are quoted separately in advance. You will always know before, never after. The full picture is in Does German health insurance pay for periodontitis treatment? (EN).
If your German is limited
Pain and language are connected more closely than people expect. If you cannot describe what you are feeling, you tend to endure it — and enduring it is exactly what nobody wants in this treatment. “It’s sharp on the upper left” is a sentence that has to arrive quickly and be understood immediately.
English is one of the working languages in our practice, so the whole appointment — the explanation, the agreed stop signal, the check on whether the anaesthetic has taken, the instructions afterwards — happens in a language you use fluently. See English-Speaking Dentist in NRW. Patients travel to us from Düsseldorf, Cologne and Bonn for this reason; twenty to thirty minutes each way is a normal distance in NRW for an appointment where being understood matters this much.
Most patients say it is comparable or easier. Both are carried out under local anaesthetic. The difference is that the periodontal appointment tends to be longer and involves more water and vibration, while there is no drilling into a tooth.
For shallow pockets and a routine cleaning above the gum line, usually no anaesthetic is needed. For instrumenting deep pockets it is standard, and it is what makes the appointment comfortable enough for the work to be done thoroughly. Being properly numb is not an optional luxury here — it is what allows the treatment to be complete.
Usually two to three hours, sometimes a little longer in the lower jaw. Avoid chewing and hot drinks until sensation has fully returned.
Almost never. Cold sensitivity after treatment is common and typically fades over one to two weeks as the exposed root surfaces adapt. Desensitising toothpaste helps; if it persists beyond a few weeks, tell us, because there are effective in-practice options.
Most people do, either the same day or the next. You will be numb for a couple of hours and your mouth may feel tender, so an afternoon appointment before a quiet evening is a sensible way to plan it.
They are additional measures used alongside the mechanical cleaning, not gentler alternatives to it. The comfort of the appointment comes from the anaesthetic, not from which supportive technology is used. Anyone presenting a laser or ozone as a way to skip the cleaning of the root surfaces, or to do without anaesthetic, is overstating what these measures do.
The honest summary: expect pressure, vibration, water and a numb lip, not pain. Expect a couple of tender days and a fortnight of cold sensitivity afterwards. Expect the measuring appointment — the one nobody warns you about — to be the sharpest few seconds of the whole course, and expect it to be easier the second time, because healed gums do not sting. And expect to be able to stop at any point simply by raising your hand. Fear of this treatment is common, understandable, and in most cases considerably larger than the treatment itself.
