An abscess is an encapsulated package of pus which is created by an inflamed tissue reaction. The cause is most often a deeply destroyed, dead tooth. A dental abscess usually causes great pain and leads to a swelling of the cheek.

Amelogenesis imperfecta
The amelogenesis imperfecta is a genetically-induced disturbance in the development of dental enamel. The dental enamel is not fully developed and appears yellowish, coarse and deformed.

Ankylosis is the ossification of the tooth retention apparatus. The affected tooth is at a lower position in the jaw bone than the other teeth and does not grow with them.

Aphthe (aphthous ulver)
An aphtha is a painfully infected area of the mucous membrane of the gums, the oral cavity or the tongue. Aphthae can be extremely painful, but they are not contagious and heal by themselves within a few days.

Aesthetic Placeholder

The aesthetic space maintainer has no medical necessity . It can be fixed or removable and replaced the missing maxillary anterior teeth.


Dentitio difficilis
Dentitio difficilis describes the restricted breakthrough of the permanent teeth (also of the wisdom teeth).

A desensibilitation is a sensitive child-oriented approach of patients to the dental treatment.

Distal Shoe
A distal shoe is a permanently fixed placeholder. Using a guiding rod it assists the remaining tooth, which has not yet broken through, in growing to the correct position.

Dormicum (Midazolam) is a medicinal sedative administered by the anesthetist and used especially in pediatric dentistry.


ECC is the abbreviation for ‘early childhood caries’ and means ‘early milk tooth caries’, also known as ‘baby bottle caries’. It can already start with the breakthrough of the first milk teeth and is usually caused by the constant sucking on feeding bottles.

In dentistry erosion means the loss of hard dental tissue caused by acids (e.g. contained in acidic beverages like iced tea, Coca-Cola or juices).

To excavate mean to ‘hollow out’, it describes the removal of infected tooth material.

Extraction means ‘pulling ou’, e.g. when extracting teeth


Fissures are natural crevices and furrows on the dental surface of molars. Deep fissures offer a good possibility for adhesion to leftovers and thus bacteria and are often not reachable with a toothbrush. In order to contain the caries risk a fissure sealing with synthetic material is recommended.

A fistula is an unnatural, tubular connection between an inflamed tooth and the surface of the gums.


Gingivastomatitis herpetica

Herpetic gingivostomatitis (also called “trench mouth”) refers to the initial infection with the herpes simplex virus. Symptoms include painful blisters in the mouth, often paired with a high fever.

Gingivitis is an infection of the gums, most often caused by plaque.


Herpes Labiales
Herpes labiales denotes the recurrence of the herpes simplex virus. The symptoms are vesicles on the lips, the entrance to the nose or the corners of the mouth. They are caused by stressful situations like colds or stress.

The term hypoplasia is used when the dental enamel is underdeveloped or imperfectly developed. It is often discolored in a yellow-brownish way and has a coarse structure. This disease may have different causes.


An injection describes for instance the application of the anesthetic syringe.

An intrusion denotes a tooth which was pressed into the tooth socket by force, e.g. in an accident.


Local anesthesia
A local anesthesia is a local sedation of the area to be treated. It is applied using a syringe.


A matrix is a thin metal band which is used to lay an inter-tooth filling.


Nitrous oxide (laughing gas)
‘Laughing gas’ is the trivial name for nitrous oxide, an anorganic, colorless gas with a mildly sweet smell. In medicine nitrous oxide is used as an analgetically (against the pain) acting sedative gas. It is the oldest anesthetic mean and among the ones with the least side effects.

Nu-smile crowns
Nu-smile crowns are confectioned steel crowns with a white plastic cap.


OPT is the abbreviation of Orthopantomogram and, in dentistry, indicates a diagnostically highly expressive X-ray picture of the entire upper and lower jaw.


Periondontosis is a bacteriologically induced inflammation, which is established as a largely irreversible destruction of the tooth retention apparatus (Parodontium). Periondontosis is caused by bacteriological plaque.

Plaque simply means coating of the tooth. It is a biological film on the teeth consisting of saliva components, bacteria and leftovers, especially situated on areas which are difficult to access. Plaque is the prerequisite for the development of caries and periondontosis.

An early lost baby tooth is replaced by a fixed or removable placeholder to keep the gap free for the permanent tooth later on.

Prophylaxis means ‘obviation’ or ‘prevention of diseases/illnesses’. In dentistry prophylaxis encompasses different measures, e.g. professional tooth cleaning, education and brushing school as well as regular check-ups.

Proximal Caries
Proximal caries is the term for caries in the area between the teeth. It especially occurs with teeth that stand close together and, in the early stages, can only be detected on an X-ray. Proximal caries can be prevented by regularly flossing the teeth.

The dental pulp fills the cavity in the crown and root of the tooth. It consists of connective tissue, blood vessels, nerves and lymphatic vessels.

Pulpitis is an inflammation of the pulpa, i.e. the tissue of the tooth interior.


Retained means ‘held back’ and describes a tooth which is not yet broken through, i.e. it is still lying in the jaw bone.


In medicine sedation means the medicinal pacification of the patient.

Stomatitis simplex
Stomatitis simplex is an unspecific inflammation which often occurs as a side effect of feverish infectious diseases or a changed state of defense. Typical symptoms are reddening and swelling of the oral mucous membrane.


Total luxation
The tem total luxation (also avulsion) is used if a tooth was completely knocked out.


Vital amputation
In a vital amputation (also pulpotomy) the inflamed part of the nerve tissue (pulpa) in the tooth is removed.


Xylit is a sugar substitute (E 967). What is so special about xylit is ist caries-inhibiting effect which was shown in different clinical studies. It is contained in many sweets and chewing gums which are gentle on the teeth.
