What is Diastema (Split Tooth)?

Diastema refers to the presence of gaps or separations between the teeth. These gaps, especially between the front teeth, are often considered an aesthetic issue. Diastema can often occur due to genetic and anatomical factors such as the size of the teeth, jaw structure, the shape of the teeth or whether teeth are missing.

What is Diastema (Split Tooth)?

Treatment of diastema can vary depending on personal preferences and the condition. Treatment options may include orthodontic treatment (braces and wires), cosmetic filling, veneers or dental implants. These treatments are determined depending on the size and cause of the diastema and the patient's wishes. It is important to consult a dentist or orthodontist for treatment planning.

Why Diastema (Split Tooth) Occurs

Diastema, or a split tooth, can occur for several different reasons. These include genetic, anatomical and various dental health factors. Some of the factors that can cause a split tooth:

Genetic Factors: Genetic factors, which are passed down through the family, can have an effect on tooth structure and positioning. If a family member has diastema, this condition can also be seen in other family members.

Dental Dimensions: Imbalances in tooth size can lead to gaps between teeth, especially if the teeth are wide.

Jaw Structure: Genetic differences in jaw structure can prevent the teeth from lining up properly and can lead to split teeth.

Teeth Shape: Abnormal shapes of teeth, especially wide and irregular teeth, can contribute to the formation of gaps between teeth.

Teeth Missing: Missing teeth can cause other teeth in the jaw to shift, which can lead to gaps between teeth.


Gum Problems: Gum disease or gum recession can contribute to the formation of gaps between teeth.

The cause of diastema can vary from person to person, so it is important to consult a dentist or orthodontist in each case. The dentist will assess the individual's dentition and overall oral health and recommend appropriate treatment options.

How to Treat Separated Teeth

The treatment of diastema can vary depending on the individual's tooth structure, the causes of the diastema and personal preferences. Some common methods used to treat diastema:

Orthodontic Treatments: If the cause of diastema is the width of the gap between the teeth and the position of the teeth, orthodontic treatments may be recommended. Brackets and wires can help straighten the teeth and close the diastema. Nowadays, clear aligner systems can also be used to correct gaps between teeth.

Front Aesthetic Filling: In this method, the dentist shapes the teeth using a tooth-colored composite resin. It fills the space between the teeth and provides a smoother appearance.

Veneers: Veneers, which are thin porcelain or composite veneers, can be placed on the front surface of the teeth to help close the diastema. This method provides an aesthetic solution and can correct the color, shape and size of the teeth.

Dental Implants: If diastema is caused by a missing tooth, dental implants may be an option. Dental implants involve an artificial tooth that is placed on a titanium screw to replace the missing tooth.

Periodontal Surgery: In some cases, surgical interventions can be used if the gums are receding or asymmetrical. Gum surgery is aimed at correcting the gum line and improving the ratio between the teeth.
