Deep bite is the most common bite disorder in the European population, affecting up to 50-60% of the population.

About deep biting in general

Do you often have sensitive front teeth and a sore or clicking jaw joint?

Deep biting is the most common bite abnormality in the European population. It can affect 50-60 % of the population, many of whom are unaware that they have a deep bite. 

It's definitely worth treating the misalignment as soon as possible, as over the years it can lead to extensive wear of the front teeth, tooth sensitivity and jaw joint problems. The teeth become sensitive because they become overloaded in deep bite and the protective enamel layer is worn away. 

Deep bite treatment is now routine treatment with either Invisalign or fixed orthodontic appliances.

If you want to know more about deep biting, read on, we've collected the most important information.


When can we talk about a deep bite?

Bite differences are examined in three directions of space. The deep bite is a characteristic of the vertical plane.

In ideal tooth-row contact, the upper incisors cover 1.5-2 mm of the lower incisors.

Whenever the upper front teeth "mesh" and cover the lower incisors, we speak of a deep bite. This characteristic applies to crowded dentition and can be checked in the mirror at home.

Look at a full deep bite case.

Forms of deep bite

Deep bite takes several forms, and varies in degree and "severity". When associated with an inwardly inclined upper incisor (the initial picture shows such a case), the lower incisors are often completely obscured. This is known as overlap bite.

Symptoms and consequences


When deep biting is associated with "inward canting" of the upper incisors, overloading and wear of the front teeth is often observed. If this form of biting persists for decades, high levels of tooth wear can result in cold-hot sensitivity, chewing and eating difficulties.

In addition, the jaw is often in a reclined position, which can have a negative impact on the health of the jaw joints.

Otherwise, when the upper incisors are tilted outwards too much in addition to the deep bite, the lower incisors bite all the way to the roof of the mouth. In this case, a continuous irritation and inflammation of the gums occurs, and the upper incisors become even more "protruding".

In the case of an abscessed tooth, oral hygiene is more difficult to maintain, and plaque and tartar easily adhere, leading to gingivitis.

Smile Aesthetics

Deep biting also has a negative impact on smile aesthetics.

Excessive "downward growth" of the upper incisors causes the lower lip to obscure the edge of the front teeth when smiling:


Otherwise, the upper incisors will lean outwards too much:


Despite the fact that aesthetically the two cases look completely different, they are both a deep bite!


Causes and development of deep bite

Several factors play a role in the development of deep bite. Some forms are genetically determined, an inherited factor. In addition, facial muscle and tongue function play an important role during the period of facial development. If a proper swallowing reflex is not developed and the tongue remains at rest on the floor of the mouth, the upper dental arch becomes narrow and narrow, so that the mandible cannot move forward properly during facial development.

These muscle dysfunctions play a role in the development of chronic mouth breathing, in addition to the development of bite disorders, leading to a number of other quality of life problems. Mouth breathing is directly related to the prevalence of upper respiratory diseases, asthma and other respiratory diseases. It plays a role in the development of sleep apnoea, which can lead to reduced concentration, attention deficit, ADHD. Chronic mouth breathers also have an increased risk of cardiovascular disease

Treatment of deep bite

Treatment of deep bite should start in childhood, before the growth peak at puberty. At this time there is still an opportunity to influence facial growth.

In adulthood, deep bite can be treated by orthodontic treatment of both gums. The braces align the teeth in the dental arches. The two sets of teeth are often adjusted in relation to each other using intermaxillary elastics.

These tiny rubber rings connect the upper and lower teeth, and transmit the directional forces that harmonise the dental arches and align the teeth relative to each other.
