Diastema: Gap between teeth | Cause and Cure


The space or gap that develops between two teeth is known as a diastema. Although the most common is that it develops in the front incisors (colloquially called “blades”) it can also occur in any pair of teeth. Separated teeth are very common in little ones who still have baby teeth and it is common for this separation to disappear when they acquire their permanent dentition.


Causes of diastema

This separation can be the result of a disorder of the size of the teeth and the upper jaw, if the teeth are too small for the maxillary bone it is then that the interdental spaces are formed.

Another reason is that patients who suffer from this problem in the front teeth tend to have a very large frenulum of the upper lip and, as it grows so large, it occupies part of the space between the pair of teeth. This frenulum moves them in the opposite way to each one and makes the gap much more noticeable.

This formed gap also appears in people who have too small lateral incisors. This gives rise to the centrals distancing themselves trying to close the remaining space.

How to fix gap in teeth?

The specialist will make an assessment in relation to the age and the case. They can then provide you with various options to treat and correct the problem:

  • Maintain the gap between the pair of teeth.
  • Undergo orthodontic treatment: by using braces you get better aesthetics. In addition, it will improve the functionality that causes incorrect dental alignment.
  • Use dental veneers: use porcelain veneers on the outside of the teeth in order to have a better aesthetic.
  • Use crowns and bridges to complete the teeth or in the case of older patients resort to dental implants.
  • Another solution is usually to use retainers, they are placed inside the tooth to correct this problem.
  • Undergo a frenectomy: as the lip frenulum is too large, you can undergo a frenectomy. This procedure consists of cutting the frenulum to later rearrange it and thus make it more flexible. If this procedure is performed in children, it is very likely that the space will close on its own, but if it is performed in an adult or adolescent, the probability of requiring orthodontics to solve the problem increases.

Although it is not an urgent matter, it is important that you go to the dentist to tell you which is the right option for you. Schedule your appointment at London Dentaly and let the dentistry specialists clear up all your doubts regarding this problem and provide you with the best solutions.
