What are the Leading Causes of Diastema?

Posted by Orthofill Shopify on

Wondering why you have teeth gap or a friend of yours? and what are the causes of diastema?

Well mostly it causes by an oversized labial frenum. The labial frenum is the piece of tissue that normally extends from the inside of your upper lip to the gum just above your two upper front teeth. In some situations, the labial frenum continues to grow and passes between the two front teeth.

Diastema is defined as the spacing between a person’s teeth. This is often noticed between the two front teeth or more. This condition often affects children and should be given immediate and appropriate treatment. It occurs when there is an inordinate relationship between the size of the teeth and the jaw.

Unfortunately for adults, this condition can become permanent and will already require an orthodontic correction. In this article, we will break down all the leading causes of diastema and the possible treatment a person with the condition can take. You will also wade through a handful of preventive actions in order to avoid this dental flaw.  

Causes of Diastema

1. Teeth and Jaw Discrepancies The size discrepancy between the teeth and the jaw is one of the most common causes of having a teeth gap. This occurs when the jaw is too big while the teeth’s size is normal or if the jaw is in normal size, but the teeth are too small.

2.Teeth and Arch Discrepancies (Dentoalveolar Discrepancies) Another thing that causes this condition is the disproportion between the arch length and teeth size. This is basically due to the increase in arch dimensions that leads to the spacing between some teeth. The dentoalveolar discrepancy occurs when the anterior teeth are in normal size, but the bridgework arch is larger or when the anterior teeth are smaller, and the arch is in normal size.

3. Expanded Labial Frenum and Impaired Intermaxillary Structure Expanded maxillary labial frenum is one of the reported leading causes of maxillary diastema. The eruption of a swollen maxillary incisors and canine, teeth spacing and offhand closure of atrophy, and space in the labial frenum may occur. However, this phenomenon can also not occur if the maxillary central incisors erupt wide apart from each other.

4.Physiological Dentition Development Average teeth spacing is normally only 3mm in the lower jaw bone (mandible) and 4mm in the upper jaw bone (maxilla). Physiological teeth gap happens when the eruption of the canines closes the space between teeth.

5. Missing Teeth Another major factor to this dental condition has a missing tooth. Having a missing tooth can lead to the spacing between each tooth to worsen as other teeth are likely to move into the space.

6. Periodontitis This refers to the progressive form of gum disease, which is caused by bone loss that leads to the inflammation of gums. It can also result in the disruption of the supporting bone which may lead affected teeth to become mobile. Teeth mobility greatly results to teeth gap formation which will likely worsen over time if not given appropriate treatment ahead of time.

7. Heredity or Ethnicity One of the inevitable causes of diastema is heredity. This is because the controls of teeth size are genetically driven. This theory was supported by studies showing the genetic basis of microdontia and hypodontia.

Diastema Treatments

Many patients choose to correct diastema not because it does have bad effects on the health but because of aesthetic reasons. There are a handful of treatment procedures in order to close the gaping of the teeth.

1. Invisalign – This dental treatment involves the use of clear braces. More and more people nowadays are acquiring this treatment from their local dentist just because it is invisible, and they don’t have to deal with wearing horrendous metal braces. This clear brace is removable, making it easy for you to eat, brush, and floss your teeth.

2. Porcelain Veneers Application – The treatment basically involves the application of veneer, a thin of material which is specially made to fill in the gaps between teeth. This treatment is great for a teeth gap in a smaller width.

3. Dental Bonding – This treatment is considered as the most appealing one. The procedure involves bonding materials that are made to match the teeth color. The material is sculpted around the teeth in order to close the gap.

Prevention Measures for Diastema

If the cause of the diastema is caused by physiological dentition development, then there is, unfortunately, no way you can avoid this condition. However, spontaneous teeth gap widening can be prevented by using a brace to stop the teeth from being mobile.

On the other hand, mundane dental chores such as regular flossing and tooth brushing are the best ways to prevent this condition. The practice of proper oral hygiene is the fundamental prevention measures to avoid diastema. 


Tooth decay and gum diseases are major factors that lead to dentition gaps spacing, which can actually be evaded if the patient observes proper dental care. In Conclusion There you have it – these are the important things you need to know about diastema.

Getting to know the leading causes is indispensable in order to come up with the appropriate treatment or preventive measures. Having great teeth is one of the major attributes that boost our self-confidence. Hence, everyone should never neglect appropriate dental care before it’s too late.
