Differences between Gemination and Fusion


When most people think of dental procedures, they think of things like teeth whitening or braces. However, there are a number of other procedures that are performed regularly in dentists’ offices. One such procedure is gemination, which is the fusing together of two teeth. Another procedure is fusion, which is the splitting of one tooth into two. Both procedures have their own unique benefits and drawbacks. In this blog post, we will take a closer look at both gemination and fusion teeth. We will also discuss when each procedure might be the best option for you. So, if you are curious about these two procedures, keep reading!

What is Gemination?

Gemination is a developmental anomaly of the teeth in which a tooth bud or tooth germ fails to completely divide during crown formation, resulting in a single tooth with two crowns.

  • Gemination most often affects the permanent incisors, but can also occur in any type of tooth. Geminated teeth are more likely to be malformed and may have an irregular shape or surface.
  • They may also be smaller than normal teeth. In some cases, geminated teeth may have one root with two roots or two separate roots. Gemination is a relatively rare condition, occurring in less than 1% of the population.
  • Treatment for geminated teeth depends on the severity of the condition. In some cases, no treatment is necessary. However, if the teeth are malformed or causing problems with chewing or speaking, they may need to be removed or corrected with dental surgery.

What is Fusion?

Fusion teeth, also known as all-on-four dental implants, are a type of dental implant that is used to support a full set of dentures. The implants are placed in the jawbone, and the dentures are then attached to the implants. Fusion teeth are a more permanent solution than traditional dentures, and they provide a more natural look and feel. Fusion teeth are also more stable than traditional dentures, making it easier to eat and speak. Fusion teeth can be an option for people who have lost all of their natural teeth or who have severe damage to their teeth. Fusion teeth can also be an option for people who have difficulty wearing traditional dentures.

Differences between Gemination and Fusion

  • Gemination and fusion are two processes that can result in the formation of unusual teeth. Gemination occurs when two teeth develop from a single tooth bud, and fusion occurs when two different tooth buds fuse together.
  • As a result, gemination and fusion can both lead to the formation of teeth that are larger than normal. Gemination and fusion can also cause teeth to have an unusual shape or be less symmetrical than average.
  • However, the most significant difference between these two processes is that gemination can occur in any area of the mouth, while fusion is most commonly seen in the front of the mouth. Gemination and fusion are both relatively rare, but they can have a significant impact on a person’s dental health.


Gemination and fusion are two different ways teeth can form. Fusion is when the tooth buds merge together and gemination is when the tooth bud splits in two. Most people have a combination of both types of teeth, but it’s possible to only have one type. Each has its own benefits and drawbacks that you should be aware of before making a decision about your dental care.
