Causes of the Gaps Between Teeth

July 29, 2021by Minish Dental

It’s better to have white, well-aligned teeth. Your luck may slip through the gaps between your teeth.

In phrenology, people often talk about good physiognomy or the correlation between facial features related to wealth. Even if you don’t believe in the old saying, many people think the gaps between teeth are a major concern. Even when you smile, you may not be able to smile openly or you may even develop habits of covering your mouth with your hands. You may also have problems with your pronunciation. In terms of oral health, dental cavities and gum diseases can easily occur, so it is recommended to improve the gaps between teeth for oral health. Let’s find out what causes this problem and ways to solve it.

Why is there a gap between my front teeth?

1. Innate Causes

The size difference between jawbone and teeth

The first main cause of gaps between teeth is the size difference between jawbone and teeth. Simply put, assuming that there is a 14cm frame, and if the frame must be filled with 14 blocks, the size of the block must be uniform at 1cm to fit correctly within the frame. But if the blocks are small or gone missing, there may be gaps between these blocks. The same rule applies to our teeth. If the teeth are missing or smaller than the jawbone, there will be a space in the arrangement.

The second cause is the ‘overdevelopment of frenulum labii maxillaris’. If the frenulum labii maxillaris (a band-shaped wrinkle in the inner part of the upper lip) is overdeveloped, the gums form wrinkles between the teeth and eventually, the teeth cannot stay in place. In this case, part of the frenulum labii maxillaris must be removed to find the alignment of teeth.

2. External Causes

After receiving orthodontic treatment

Usually, orthodontic treatment is chosen to straighten out your teeth, but once the treatment is finished, there may be open spaces between them, which are called the black triangles. This happens when your teeth are removed and the rest of the teeth are not completely closed to fill in those empty spaces.

The space between the teeth is called the ‘Black Triangle’. Black triangles may appear between teeth and gums after wearing braces. This phenomenon occurs when the overlapping teeth end up being visible again. The black triangles are not aesthetically pleasing, and they can also be bad for oral health, causing food to get stuck, so other solutions may be needed.

Gum disease

The second cause is gum disease. There are differences in the degree among people, but your teeth and gums also age as you get older. Our gums hold the teeth tightly in the beginning, but once they go through the aging process or dental trauma, our teeth may start moving or shaking. In this case, the fundamental cause of gum disease should be removed through gum treatment first. However, you should be careful not to miss the time window for treatment because gum treatment does not improve your gum condition easily or instantly.

What treatments can help treat the gaps between teeth?

1. Orthodontic Treatment


Orthodontic treatment may help adjust the gaps, but it comes with disadvantages such as longer treatment periods and the patients must be putting on braces continuously during the treatment periods. 

Although the aesthetic burden of wearing braces during the treatment period has been greatly reduced due to the development of orthodontic technology, it is recommended to choose the treatment that suits you the most.

2. Resin Treatment

It is a treatment that fills open spaces using resin, a heat-sensitive material widely used for such treatment. We repeat the process of hardening by adding resin little by little, and because open spaces can be treated quickly by using dental fillings, the treatment can be done within a day on your first visit and the price of the treatment is affordable to most people.

However, during the filling and hardening process with heat, tooth cracks may appear in the treated area, and due to the nature of the material, there is a disadvantage of receiving another treatment again within just a few years due to the risk of tooth discoloration or the elimination of resin.

3. Porcelain Veneer treatment

Porcelain Veneers treatment, widely known as aesthetic therapy, can also improve the gaps between teeth. The thin porcelain veneer on the front teeth is made as wide as the original teeth to fill in the gaps. You can improve the shape and color of your teeth at the same time while filling the gaps. However, your teeth can be deleted at an appropriate level to secure more space for porcelain veneers, and the veneers are easily susceptible to damage.

Also, in the past, porcelain veneers were often recommended to cover teeth with prosthodontics, which required major tooth deletion and were likely to cause side effects such as toothache and pain after the treatment.

4. Minish Treatment

Minish treatment restores damaged teeth and gums by filling in the damaged spaces with the material that is most similar to natural teeth without unnecessary tooth deletion.

In any case, the functional recovery of your teeth is possible without damaging your teeth, and at the same time, aesthetic recovery is possible to match the oral condition and overall facial harmony. They can also be managed after treatment in the same way as natural teeth.

Minish Treatment Process

  1. Organize only the contaminated and rough surfaces of the teeth (No anesthesia required)
  2. After making an impression of the teeth, design the tooth pattern that fits each individual. (You can consult the doctors and dental technicians to choose the design and color you desire.)
  3. Combine the design of Minish orthodontics with a suitable bonding material.

Do I still need to receive treatment even if there is no problem with functionality?

If there are gaps between teeth, food may easily get stuck in between, affecting gum health. Also, the food stuck in those gaps may cause dental problems such as bad breath by creating an environment where bacteria can reproduce freely as well as aesthetic problems such as pronunciation problems.

Most of the patients who have visited us simply for aesthetic purposes have not had much damage to the enamel, the outer layer of their teeth. Minish Dental Hospital approaches such problems to the enamel layer differently, which is now recognized by academia.

Treatment to restore the properties of natural teeth not only allows the original natural teeth to be used for a long time, but also provides preventive effects to prevent dental problems in advance, reducing visits to the dentist in the future. Many people visit simply because of aesthetic problems, but Minish Dental Hospital takes various things into account, including dental health, aesthetic satisfaction, and the appearance and color of natural teeth.
