The tooth that got longer
Almost nobody notices recession happening. People notice a result: a tooth that suddenly looks longer than its neighbour, a dark line at the gum margin, a triangle of shadow between two front teeth, or a jolt of cold from tap water.
Often the trigger is a photograph. You see a picture from four years ago, look in the mirror, and the difference is unmistakable. That comparison is genuinely useful — recession is slow, and a rate of change tells a dentist far more than a single snapshot.
The question that follows deserves a straight answer rather than reassurance: is this going to cost me my teeth? For most people, no. For some, yes, if nothing is done. The rest of this article is about working out which group you are in.
What has actually moved
The gum is not a curtain that can be pulled back into place. It sits on bone and follows that bone closely. Where the bone around a root is thin or has been lost, the gum above it withdraws.
This gives you the most important distinction in the topic:
- The bone is being destroyed by inflammation. Bacterial biofilm below the gum line drives a chronic immune response, and bone is lost as collateral damage. The gum recedes because its foundation is disappearing. This is periodontitis, and it is progressive.
- The bone was always thin, or the tissue over it has been worn down. Some people are born with a delicate gum type over roots sitting slightly outside the bony envelope. Add decades of firm horizontal brushing and the tissue gives way. The support around the tooth is otherwise intact.
The second kind looks alarming and behaves calmly. The first can look modest and behave badly. That is precisely why the eye is a poor diagnostic instrument here.
The two kinds of recession, side by side
| Inflammatory recession (periodontitis) | Mechanical or anatomical recession | |
|---|---|---|
| Typical pattern | Several teeth, often the whole mouth, uneven | Single teeth, often canines and premolars, frequently on the side you brush hardest |
| Gum appearance | Red, swollen edge, bleeds on probing | Pale, firm, no bleeding — the margin just sits lower |
| Pockets | Deepened, bleeding, sometimes pus | Shallow; the gum has moved down but stays tight to the tooth |
| Bone on X-ray | Reduced around the affected teeth | Essentially normal, sometimes thin over the root |
| Tooth stability | Can become loose over time | Stays firm |
| Progression | Continues without treatment | Often stops once the cause is removed |
| The real risk | Tooth loss | Sensitivity, root decay, appearance |
Mixed pictures are common — someone with treated periodontitis who also brushes too hard has both. The examination sorts it out; the point is that the two need completely different responses.
So what is genuinely at stake
Four consequences, in the order of how much they actually matter.
1. Loss of support. Only relevant in the inflammatory group, and the reason periodontitis is treated seriously. Bone that is gone does not return on its own, and once enough has gone the tooth loosens. This is the danger the question is really asking about — and the one that responds best to being caught early.
2. Root decay. A root surface has no enamel. It is softer than the crown, and decay travels through it faster. Root caries at the gum margin is a common late finding in long-standing recession, and it is quiet — often painless until a filling is no longer straightforward. Fluoride matters more here than anywhere else in the mouth.
3. Sensitivity. Exposed roots are full of microscopic channels leading towards the nerve. Cold air on a Wuppertal platform in February, cold drinks, sweet things, sometimes the brush itself. Not dangerous, very unpleasant, and usually the reason people come in.
4. Appearance. Longer teeth, dark margins at the edge of crowns, and the dark triangles that appear between front teeth when the gum papilla shrinks. This bothers some people a great deal and others not at all. It is a legitimate reason to seek advice — but the cause has to be established before anything cosmetic is discussed.
How to tell whether yours is getting worse
Recession is not a state, it is a rate. What matters clinically is whether the margin is where it was two years ago.
What a dentist records. Recession is measured in millimetres from a fixed landmark on the tooth, tooth by tooth, alongside pocket depths, bleeding on probing and mobility. Those numbers are why a periodontal examination takes a while — and why it is worth asking for a copy. Two sets of measurements a year or two apart answer the progression question definitively; no amount of looking in a mirror can.
What you can do at home. Take a photograph. Same lighting, lip retracted with a finger, front teeth and both sides, once or twice a year, dated on your phone. It sounds fussy and it is the most useful record most patients ever produce. If you have holiday photos with a broad smile, you already have a baseline.
What can be done — realistically
The order matters. Every option below is worth less if the cause is still running.
Stop the cause first. If it is inflammatory, that means periodontal therapy: the biofilm on the root surfaces removed and the aftercare kept up. If it is mechanical, it means changing the brushing pattern — a soft brush, no horizontal scrubbing, light pressure, a pressure sensor if the habit is stubborn. Grinding is addressed with a night guard (Knirscherschiene), and a lip or tongue piercing that rubs a gum margin does measurable damage.
Treat the sensitivity. Toothpaste for sensitive teeth used consistently, fluoride varnishes applied at the practice, and in some cases sealing the exposed area. Most sensitivity improves within a few weeks, and much of it settles as the root surface mineralises over time.
Protect the root from decay. Higher-fluoride products, cleaning the margin properly, and reviewing sugary or acidic habits — sparkling water and citrus all day are harder on exposed roots than people expect. Where decay has started, a filling at the gum margin is a routine repair, and a tooth-coloured filling can also rebuild a worn notch at the neck of a tooth and reduce sensitivity in one step.
Surgical root coverage. For selected single teeth — good bone, healthy gum, no active inflammation, a suitable defect shape — a graft of connective tissue taken from the palate can cover an exposed root. It works well in the right situation; it is not a general solution for widespread recession, and no honest practice promises a specific final position of the gum margin. One point about cover is worth being clear on: the surgical treatment of recessions (mukogingivale Chirurgie) is explicitly excluded from the statutory catalogue, so it is a private service billed under the German private fee schedule for dentists (GOZ). You should have the individual steps and the cost in writing before you decide.
What does not work. No toothpaste, gel, oil or supplement regrows gum tissue over a root. What genuine products do is reduce sensitivity and support the tissue still there — worth having, described accurately.
Where the German system fits in
If your recession is inflammatory, the paperwork works in your favour. Periodontitis therapy is a statutory benefit running on its own approved plan: the dentist records the findings, sends a treatment plan to your health insurance fund, and the fund approves it before treatment starts. The approved pathway then covers the explanatory appointment, hygiene instruction, cleaning of the root surfaces below the gum line, a re-assessment months later and a structured aftercare programme (supportive periodontal therapy, UPT) running for years — with no co-payment for the covered services. Details in Does statutory health insurance pay for periodontitis treatment? (EN).
What sits outside it: professional cleaning (professionelle Zahnreinigung, PZR), and anything done purely to improve the appearance of the gum margin. Those are offered separately and in writing, always before they happen. The clinical side is described on our Periodontitis treatment – service page (EN).
What is normal — and when to have it looked at
Situations that change the picture
Orthodontic patients. Moving a tooth outwards through thin bone can uncover a root. Modern planning takes this into account and gum condition is assessed before treatment; if you are wearing clear aligners (Aligner) or fixed braces (feste Zahnspange) and notice a margin dropping, raise it during treatment rather than after it.
Smokers. Tobacco constricts the small vessels in the gum, so the tissue bleeds less while the underlying disease progresses more freely. A smoker with receding gums and no bleeding is not in the reassuring group.
Diabetes. Poorly controlled blood sugar amplifies periodontal inflammation, and the relationship runs both ways. Bringing your HbA1c into a dental appointment is not oversharing; it is directly relevant.
People with naturally thin gums. A family pattern of delicate, pale tissue is real. It does not doom you to anything, but brushing pressure and instrument technique matter more for you than for others — worth saying out loud at your appointment.
New to Germany, or working in English. Recession is a topic full of measurements and judgement calls, and it is hard to follow in a second language. You do not need a referral to see a dentist here; you choose the practice yourself. Many expats in Düsseldorf, Cologne or Bonn think nothing of a 20 to 30 minute journey to a practice where the conversation happens in English — see English-Speaking Dentist in NRW.
No. Gum tissue that has withdrawn from a root does not return on its own, and no product regrows it. What excellent care achieves is stopping further loss — the outcome that actually protects the tooth. Where a single tooth is suitable, a surgical graft can cover an exposed root, but that is a specific procedure for a specific situation.
No, and this is the most common misunderstanding. Much recession is mechanical — hard brushing, thin tissue, tooth position, piercings — with healthy bone underneath and no risk to the tooth. Periodontitis recession comes with deepened pockets, bleeding and bone loss on the X-ray. Only an examination distinguishes them.
Sometimes, partly, depending on the cause. Once the gum papilla between two teeth has shrunk, rebuilding it predictably is difficult. Options range from small composite additions that narrow the gap to orthodontic reshaping of the contact point. Any assessment should start with why the papilla was lost.
It revealed it. Inflamed tissue is swollen and sits higher than the bone beneath it; once the inflammation resolves, it shrinks to its real level. That is a sign the treatment worked rather than a complication, and the sensitivity in that phase usually settles.
Not in itself — pressure and technique do. A rotating or sonic brush used with heavy hand pressure can do more damage than a manual one, while the same brush used lightly, with the pressure sensor respected, is often gentler than manual scrubbing. If your bristles splay outwards within a month, you are pressing too hard whatever the brush.
Receding gums are a symptom, not a diagnosis, and whether they are dangerous depends entirely on what is happening to the bone underneath. Inflammatory recession is worth treating promptly: that is the version that ends in loose teeth. Mechanical recession is worth understanding and adapting to, because ignored it ends in cold-sensitive teeth and root decay. Neither reverses by itself, both can be stopped, and the measurement that tells you which one you have takes a single appointment.
