What Are Genetic Disorders that Affect Teeth

Genetic Disorders That Affect Teeth

Genetic mouth and dental abnormalities affect the development and appearance of the teeth and supporting structures. According to the National Center for Biotechnology Information, patients with potential dental genetic disorders should visit the dentist in early childhood. This allows your dentist to make an early diagnosis and modify you or your child’s dental care to account for complex conditions. Additionally, some abnormalities require specialists in dental genetic disorders. 

Periodontal disease and dental caries (cavities) have also been linked to inherited traits. Knowing the genetic disposition of clients can assist your dentist in providing comprehensive dental care, according to the American Dental Association.

Types of Genetic Oral/Dental Abnormalities

Here are the most typical genetic disorders that affect teeth, health, and appearance.

Cleft Lip & Cleft Palate

This is the most common craniofacial deformity linked to family history. It involves the incomplete fusion of the lip or palate.


Anodontia is a congenital defect causing missing teeth. Children born with this defect usually get their baby teeth but have one or more missing primary teeth. This disorder can cause spacing errors due to third molars, upper lateral incisors and lower second premolars that fail to develop.

Amelogenesis Imperfecta

Amelogenesis imperfecta involves defective tooth enamel, which is the hard substance protecting the tooth crown. This leaves teeth sensitive to temperature and prone to wear. 

Supernumerary Teeth

Some people have extra permanent teeth that may not emerge. Those that do emerge can appear anywhere in your mouth. They often have a cone-shaped crown with a short root.


Known as bad bite, this disorder causes crowding due to the incorrect number of teeth and misalignment of the jaw. Surgical and nonsurgical interventions can restore function and reduce pain.

Gum Disease

Gum disease results from a bacterial infection that damages the tissues supporting your teeth. The disease can be reversed with proper dental care and hygiene. Heredity also impacts your likelihood to develop gingivitis, which is linked to diabetes, stroke and heart disease.

Gingival Fibromatosis

This overgrowth of gum tissue is caused by collagen overproduction.

Oral Cancer

Oral cancer starts as a white or red spot in the mouth. Most oral cancers involve alcohol or tobacco use in patients over age 40. However, genetics also play a factor.

Canker Sores

Canker sores are white or gray ulcers with a red border inside your mouth. They are caused by immune system deficiencies and bacterial infections. Hereditary predisposition may also play a role in the frequency and probability of getting them.
