The key difference between gemination and fusion is that germination is a dental phenomenon where two teeth form from a single tooth root, while fusion is a dental phenomenon where two different developing teeth join together to create one tooth.
Dental health is a very important aspect of quality life. Problems with teeth or gums can cause pain and other issues. Gemination and fusion are two dental phenomena that are often confused with each other. However, gemination is the complete opposite of fusion. Children are predominantly affected by these two dental phenomena.

What is Gemination?
Gemination occurs when a developing tooth of a child splits into two. Thus, two teeth are created from a single tooth root in this condition. The exact cause of this condition is not known. However, there are possible factors contributing to this condition, such as vitamin deficiency, hormonal irregularities, infection or inflammation in areas near the developing tooth bud, drug-induced genetic predisposition, and radiotherapy. Signs and symptoms of this condition may include misaligned teeth leading to chewing difficulties, teeth deviation, asymmetry of the dental arch, aesthetic concerns, obstruction of adjacent tooth eruption, and difficulty in cleaning the dental surface. These factors can increase susceptibility to dental decay and periodontal disease.
Gemination can be diagnosed through clinical dental examination and radiographs. Furthermore, treatment options for gemination may involve maintaining excellent oral hygiene to prevent plaque buildup, using fissure sealants and resin restorations for deep grooves, orthodontic procedures for alignment, reshaping and restoring affected teeth, root canal treatment if necessary, as well as extraction and transplantation of supernumerary teeth to replace the geminated tooth.
What is Fusion?
Tooth fusion occurs when two separate tooth buds grow together and form into one tooth. Therefore, fused teeth may have two separate tooth buds, pulp chambers, and canals. However, upon extraction, they will still be fused together as one solid tooth. Moreover, signs and symptoms of this condition may include dental caries, periodontal disease, and aesthetic impairments or problems. Tooth fusion is caused by physical force or pressure during tooth development and genetic variations for genes such as ERCC6, OBSCN, SLC27A3, and KIF25.
Tooth fusion can be diagnosed through family history, clinical dental examination, and X-ray. Furthermore, treatment options for tooth fusion may encompass root canal treatment for the fused teeth, hemisection to eliminate deformed fragments, the restoration of the remaining teeth to their normal shape using crowns or composite resin, and orthodontic procedures to address alignment issues.
What are the Similarities Between Enteric Gemination and Fusion?
- Gemination and fusion are two dental phenomena.
- Children are predominantly affected by these dental phenomena.
- Both phenomena can be diagnosed through clinical dental examination.
- They can be treated through dental procedures such as root canal treatment, dental restoration, and orthodontic procedures.
What is the Difference Between Enteric Gemination and Fusion?
Germination is a dental phenomenon where two teeth form from a single tooth root, while fusion is a dental phenomenon where two different developing teeth join together to create one tooth. Thus, this is the key difference between gemination and fusion. Furthermore, gemination can be seen frequently in adults, while tooth fusion is very rarely seen in adults.

FAQ: Enteric Gemination and Fusion
How to differentiate between fusion and gemination clinically?
Pulpal anatomy is useful in differentiating these double teeth. Fused teeth have a separate pulp chamber and root canals, while geminated teeth usually show a single big root and root canal.
What causes fusion and gemination?
The exact cause of gemination is not known. Tooth fusion is caused by physical force or pressure during development and genetic variations for genes such as ERCC6, OBSCN, SLC27A3, and
Is fusion or gemination more common?
Both tooth gemination and fusion are rare conditions.
Summary – Enteric Gemination vs. Fusion
Gemination and fusion are two dental phenomena or problems predominantly observed in children. Germination is a dental phenomenon that occurs when two teeth are created from a single tooth root, while fusion is a dental phenomenon where two different developing teeth have joined together to create one tooth. So, this summarizes the difference between gemination and fusion.
