Frequently Asked Questions


The teeth are most sensitive close to the gums. This is often provoked by contact, brushing or cold drinks. The sensitivity can fluctuate or temporarily disappear altogether.

Potential causes:

Exposed tooth neck after the gums have receded, often with a notch-shaped cavity
Brushing too vigorously in a horizontal direction
Teeth grinding and excessive strain on the teeth

Treatment options

Reducing the sensitivity using varnish-like coatings
Filling the notch-shaped cavities
Reducing the strain on the teeth by filing them down or wearing a mouth guard
Plastic-surgical relocation of the gum to cover the exposed tooth neck


When eating or drinking cold, hot and often also sweet food or drink, a nagging pain can develop, only lasting for a relatively short period (seconds to a few minutes).

Potential causes

Tooth decay in the painful area
Leaky fillings or crowns
The start of pulp inflammation

Treatment options

Careful examination, usually with the aid of X-rays
Removal of the tooth decay
Addition or replacement of fillings or crowns
Sometimes with additional removal of the pulp and subsequent root canal treatment


When teeth hurt under strain, so for example when chewing, the range of possible causes is extensive. Often this means the foundations of the teeth are inflamed. This is caused by microorganisms. These can cause discomfort either due to diseased pulp (inside the tooth) or an inflamed gum line.

If the pulp is responsible, a root canal treatment is usually necessary. In the case of inflammation originating in the gums, the tooth is thoroughly cleaned and medication is administered to it. It is only necessary to consider removing the tooth if the inflammation is already well advanced.

Excessive strain can also cause pain when biting. This can be relieved by lightly filing the tooth or wearing a mouth guard. Occasionally the tooth is broken as a result of excessive strain. The most appropriate treatment depends on the path of the breakage.

Crowns or bridges that have detached from the tooth stump also hurt when the teeth are clenched. These then have to be reattached by the dentist.

Sometimes teeth which have only just been given new fillings, inlays, crowns or bridges are also painful. This could be caused by temporary irritation of the pulp or excessive strain from biting down too hard.

Potential causes

Inflammation of the pulp (rather isolated pain)
Inflammation originating in the gums (rather dull, radiating pain).
Excessive strain from teeth grinding or biting down too hard.
Tooth breakage
Loose crowns, bridges, fillings or inlays.
Treatment options

Root canal treatment
Gum treatment
Filing or mouth guard
Reattachment of loose crowns, bridges or similar.


The tendency to bleed, even when brushing carefully, is a sign of gum disease. Usually it is a case of inflammation caused by microorganisms. Thorough, professional tooth cleaning is always required in order to largely eliminate this. All of the hard and soft deposits are removed from the teeth. Not only do these discolor the teeth, but they also provide an undesirable hiding place for microorganisms.

Potential causes

Hard and soft tooth deposits
Protruding edges of crowns and fillings
Treatment options

Thorough, professional tooth cleaning
Treatment of the periodontium in advanced cases
If necessary: replacement of crowns and fillings

Mögliche Ursachen:

  • Mikroorganismen
  • Harte und weiche Zahnbeläge
  • abstehende Ränder von Kronen und Füllungen


  • intensive professionelle Zahnreinigung
  • Behandlung des Zahnhalteapparates in fortgeschrittenen Fällen
  • bei Notwendigkeit: Erneuerung von Kronen und Füllungen


If teeth start to migrate, meaning they change position, rotate, tilt or begin to “grow”, it often leads to undesirable changes. Gaps form or individual teeth get longer or become crooked. Not only can this spoil the esthetic appearance. Food particles often get stuck in the new nooks and crevices, which are also more difficult to clean.

This can occur if the foundations of the teeth (periodontium) become weaker. Inflammation leading to bone loss is usually responsible for this. Continuously applied forces can also move teeth. This includes teeth grinding, for example.

Potential causes

Tooth foundations weakened by bone loss
Teeth grinding
Habitually chewing on a pipe or pen, for example.
Treatment options

Gum treatment
Wearing a teeth grinding guard (occlusal splint)
Shifting the teeth into the desired position (orthodontics)
Small changes to the shape of the teeth by means of “esthetic contouring” or ceramic veneers (laminate veneers)
More extensive changes with crowns and bridges

Dies kann dann geschehen, wenn das Fundament der Zähne (Zahnhalteapparat = Parodontium) schwächer wird. Entzündungen, die zum Knochenabbau führen, sind dafür zumeist verantwortlich. Aber auch stetig einwirkende Kräfte können Zähne wandern lassen. Hierzu zählt z.B. ständiges nächtliches Knirschen.

Mögliche Ursachen:

  • durch Knochenabbau geschwächtes Zahnfundament
  • Zähneknirschen
  • ständiges Kauen auf z.B. Pfeife oder Kugelschreiber


  • Zahnfleischbehandlung
  • Tragen einer Knirscherschiene (Aufbissbehelf) Verschiebung der Zähne in die gewünschte Position (Kieferorthopädie)
  • kleine Veränderungen der Zahnform durch “esthetic contouring” oder Keramikschalen (Laminate Veneers)
  • grössere Veränderungen mit Kronen und Brücken


Over the course of your life, teeth can naturally become darker. There may be more or less severe discoloration to one or several teeth as a result of the effects of staining or diseases.

Potential causes

Contamination of the tooth surface as a result of deposits or staining (red wine, tea, smoking etc.)
Old fillings with rough surfaces and leaky edges
“Aged” teeth with thin enamel
Individual teeth with diseased pulp
Treatment options

Thorough cleaning and polishing of the tooth surface
Bleaching individual teeth or all visible teeth
Replacement of fillings
Addition of veneers (bonded ceramic veneers)

Mögliche Ursachen:

  • Verunreinigung der Zahnoberflächen durch Beläge oder Farbstoffe (Rotwein, Tee, Rauchen etc.)
  • Alte Füllungen mit rauhen Oberflächen und undichten Rändern
  • “gealterte” Zähne mit dünnem Schmelz
  • einzelne Zähne mit erkranktem Zahnmark


  • intensive Reinigung und Politur der Zahnoberflächen
  • Bleichen von einzelnen oder allen Zähnen im sichtbaren Bereich
  • Erneuerung von Füllungen
  • Anfertigung von Veneers (geklebte keramische Verblendschalen)
