In Turner Syndrome it is common to see abnormal dental development. At the time of diagnosis, a complete dental and orthodontic examination will screen for any such abnormalities. Skeletal malocclusion is caused by distortion of proper mandibular and/or maxillary growth during fetal development which, if untreated, may lead to dental deformities, bruxism, teeth-crowding, trismus, mastication difficulties, breathing obstruction and disturbed digestion. Therefore, dental/orthodontic evaluation at diagnosis if no previous dental/orthodontic care was established. Future management and follow-up should be based on the standard of dental/orthodontic care, individual clinical findings, and patient needs.
Commonly seen features in girls/women with TS:
- Variation in tooth eruption
- Changes in crown and root development
- Increased risk for root absorption or tooth loss during orthodontic treatment
- Retrognathic lower face (including a recessed and small mandible)
- Increased cranial base angle and abnormal palate (382)
- Distal molar occlusion
- Large overjet and lateral cross-bite
- Anterior and lateral open bite
- Smaller primary and permanent teeth with two-rooted mandibular first and second premolars (383)
- Permanent dentition often erupts 12 months earlier than that in controls (range 6 months–3.5 years).
- The teeth have thinner enamel and abnormal dentin (384).
- The palatal and gingival indices are abnormal and there is higher- than-normal tooth mobility (385).
- Decreased crown width is commonly found (386)
Paradoxically, the prevalence of caries is significantly lower despite the findings of poorer oral hygiene when compared with controls (385).
Dental Health Considerations & Solutions in Patients with Turner Syndrome
Females with 45,X or with 45,X/46isoXq mosaicism have more severe oral and dental anomalies, while those with a 45,X/46,XX karyotype tend to have abnormalities in line with the general population (386).
Historically, it was believed that females with TS have a ‘high-arched palate’. Recent research indicates that palatal height is not affected, as a narrower dental maxillary arch with the presence of lateral palatal ridges gives the false illusion of increased palatal height (387). A low tongue position may further contribute to oral and dental pathology (388).
Cleft palate is occasionally reported in females with TS; thus, early diagnosis and treatment are recommended to minimize adverse effects on speech development (389). Reference- 2017 International Guidelines

Early steps to good oral health in your child:
Dental Issues In Turner Syndrome
- Clean your child’s mouth twice a day even if he/she does not have teeth yet. Wipe his/her gums with gauze. Anything that touches someone else’s mouth should not be allowed to touch his/her mouth.
- Once the first tooth appears, use a soft-bristled toothbrush and water to brush your child’s teeth.
- Children should have their first dental visit around the time of their first tooth eruption and no later than age 1.
- There should be 20 teeth in your child’s mouth by age 3.
- Never put your child to sleep with a bottle containing anything but water.
- Routine exams should occur every six months or as determined by your child’s dentist.
- Once your child learns not to swallow toothpaste, brush his/her teeth with a rice-sized speck of fluoride toothpaste.
