Periodontology – diseases of the gums and the jawbone

Keeping your own teeth for as long as possible: that wish lies at the heart of a dentistry built on prevention. Careful oral hygiene at home and professional support at the practice are not opposites but two halves of the same path – and they save elaborate treatments later on.

The tooth-supporting apparatus carries every single tooth. Once it is lost, it does not grow back. That is why with periodontal diseases it is not the method that decides the outcome but the timing: the earlier it is recognised, the more can be preserved.

How to recognise a periodontal disease

Periodontal diseases usually run their course without pain. They are therefore often noticed only at a late stage. Possible signs of gingivitis or periodontitis:

  • Red, swollen gums
  • Gums bleed when touched
  • Receding gums and long tooth necks
  • Pain in the teeth and gums
  • Teeth become loose or move
  • A bad taste, troublesome bad breath
  • Bone loss on the X-ray

At an advanced stage, tissue is lost irretrievably. An early diagnosis and treatment are therefore decisive. If you notice one or more of these signs, go to your dental practice – the medical history will go into such observations in detail.

Periodontitis – a widespread disease

Periodontitis is one of the most common diseases of all; about three out of four adults are affected in the course of their lives, many without knowing it at first. The cause is bacteria that gather between tooth and gum. If these deposits are not thoroughly removed, they harden into tartar. Redness, swelling and a tendency to bleed follow.

If that is left untreated, the inflammation destroys the fibres that hold the tooth in the jaw and spreads to the bone. Without fibres and bone the teeth become loose – and may be lost. The disease is often called periodontosis in everyday speech; technically that is something else.

The three subjects asked about most often

Periodontal Screening Index (PSI)

The PSI shows within a few minutes whether periodontal treatment is necessary. The examination is painless, and the finding gives the personal risk of disease.

Professional tooth cleaning

It is one element of every modern prevention concept. Every natural tooth kept is better than the best replacement – and the cleaning is the cheapest part of the way there.

What is periodontitis?

An inflammatory disease of the structures holding the tooth – regardless of age, on one tooth or on many, advancing at different speeds and in varying degrees of severity.

The essentials at a glance

  • Periodontitis is an inflammation of the tooth-supporting tissues – the gums, the periodontal ligament and the jawbone.
  • It usually runs its course without pain and is therefore often noticed late.
  • The first signs are reddened, swollen gums, bleeding when brushing and persistent bad breath.
  • Left untreated, jawbone is lost, teeth loosen and may fall out. This loss cannot be reversed.
  • The earlier treatment begins, the more tooth substance can be preserved.

Answered briefly

Frequently asked questions

The cost depends on the steps involved and on which teeth are affected, so it differs from patient to patient. Before treatment begins, the practice draws up a treatment and cost plan setting out the charges. It also shows which costs the statutory health insurer covers and which additional services you have to pay for yourself.

An implant can last many years – what matters is how healthy the surrounding tissue stays. Anyone who has had periodontitis carries a higher risk: the same bacteria can attack the tissue around an implant. This is known as peri-implantitis.


Periodontitis should therefore be fully treated before an implant is placed. After that, aftercare decides the outcome: regular check-ups, professional cleaning and careful oral hygiene at home. On those terms, implants remain a reliable solution even after periodontitis.

Follow your dentist's instructions closely. They will tell you exactly what to watch out for.

A single application of enamel matrix proteins is normally sufficient. The regenerative process they set in motion continues over a longer period – often for more than a year.

Consistent oral hygiene is the key. Your practitioner will tell you whether further rules apply in your case – cutting down on smoking or giving it up, for instance.

Periodontal disease is usually caused by bacteria that settle between tooth and gum and trigger an inflammation. Existing systemic conditions such as diabetes, stress or inadequate oral hygiene can also influence how the disease progresses.

The first signs of periodontal disease are red, swollen gums, bleeding gums, receding gums, pain in the teeth and gums, loosened teeth, a bad taste in the mouth and bad breath.

Bleeding gums can be a sign of periodontal disease. If it happens regularly, for example when brushing, you should consult your dentist.

During the active phase of treatment your dentist sets the intervals between appointments; depending on the stage of the disease these can be close together. Even without periodontal disease you should attend a check-up once or twice a year.

Detected in time, the progress of periodontal disease and the loss of one or more teeth can be prevented in most cases. If a tooth is already damaged beyond saving, removal is often the only option.

Connections exist with diabetes mellitus in particular, where poorly controlled blood sugar is a risk factor. Caries, stress or a generally weakened immune system can also encourage periodontitis. Periodontitis is in turn considered a risk factor for heart disease, for the premature birth of underweight babies and for arthritis. Hormonal changes during pregnancy can likewise trigger periodontal disease.

Gingivitis can be treated by improved and consistent oral hygiene. If gum problems persist, a dentist should always be consulted.

Depending on how far the periodontal disease has advanced and on the wish to keep the affected tooth, a surgical procedure may be unavoidable. Your dentist will tell you whether it is necessary in your case.

Yes, periodontitis can be transmitted – for example by sharing a toothbrush or cutlery, or by moistening a dummy in your own mouth.

Recent studies have shown that tissue rebuilt with the help of enamel matrix proteins was still stable after five years.

In the worst case, untreated periodontal disease leads to the loss of the affected tooth or teeth.
