(13), the most common dental associated with Down syndrome are variations in tooth number and morphology. Tooth eruption may be delayed, may occur in an unusual order and can be 2 to 3 years behind a child's normal eruption pattern.
What syndromes are associated with delayed tooth eruption?
Other genetic conditions may also contribute to an altered eruption time, such as Down syndrome, amelogenesis imperfecta and regional odontodysplasia. Premature birth or low birth weight: Babies who are born significantly early may experience a range of developmental delays, and tooth eruption can be one of them.
Often delayed tooth eruption comes down to genetics. Ask your parents and your spouse's parents and odds are there's a family pattern at play, especially if the delay isn't significant. Other reasons for delayed tooth eruption include: Prematurity.
In Down's syndrome, eruption of the deciduous and permanent teeth is delayed as compared with general population. The causes of delayed eruption in Down's children are unknown, due to lack of information on the factors intervening in the process of normal eruption.
Natal teeth may be more likely to occur in children with certain health problems that affect growth. This includes Sotos syndrome. The condition can also be linked to Ellis-van Creveld syndrome (chondroectodermal dysplasia), pachyonychia congenita, and Hallermann-Streiff syndrome.
Hypodontia (missing teeth), is a congenital condition which is characterized by one to five missing permanent teeth (not including the third molars/wisdom teeth) due to lack of development. Hypodontia is a type of tooth agenesis, a common developmental anomaly involving the absence of teeth.
They are, however, usually associated with other conditions such as Fabry disease, Ellis-van-Creveld syndrome, Nance-Horan syndrome, Rubinstein-Taybi syndrome, Gardner's syndrome, cleidocranial dysostosis, and trico-rhino-phalangeal syndrome.
Deficiencies in vitamins and minerals can delay teething. Specifically, deficiencies in vitamin A, vitamin C, vitamin D, and calcium can impact when teeth come in. Vitamin D is crucial for calcium absorption, and a lack of these nutrients can weaken the bone structure necessary for teeth to emerge.
Some will get their teeth sooner, others will get them later. By the age of 3 years, on average, children will have a full set of 20 primary teeth. Many children with delayed tooth eruption are well into their first year of life without their first tooth. For a lot of parents, this causes alarm.
When should I worry about baby teeth not coming in?
Teething in babies happens between 4 and 15 months of age. Delayed or late teething is normal these days and not a cause for concern until your baby is 15 months old. If the delay is longer than 18 months, you should consult a pediatric dentist, says the American Academy of Pediatrics.
The late loss of baby teeth does not directly affect the onset of puberty. The processes of losing baby teeth and going through puberty are separate from one another and are controlled by many bodily processes.
A tooth generally takes around eight or so days to fully emerge. In some cases, it may take longer or shorter. Every child is different, and variations in teething timelines are entirely normal. Consult a reputable pediatric dentist if you have concerns about your child's teething schedule.
Genetics: Several genetic disorders can trigger a delay in tooth eruption, such as Down syndrome, Cleidocranial dysostosis, and Apert syndrome. Some rare genetic abnormalities can cause poorly formed teeth and late tooth appearances, such as amelogenesis imperfecta and regional odontodysplasia.
In particular, it was discovered that 70% of kids with delayed teething and just 30% of kids with normal teething development were vitamin D deficient. In India, children's and babies' delayed teething is linked to vitamin D insufficiency.
What nutritional deficiency causes delayed tooth eruption?
A strong association exists between the timing of eruption of primary teeth and Vitamin D deficiency, and it can be concluded that Vitamin D deficiency could be an etiological factor for delayed eruption. Socioeconomic status was a contributing factor for Vitamin D deficiency.
Causes of Delayed Tooth Eruption Sometimes delayed tooth eruption is simply due to normal heredity. If one parent or sibling had teeth come in late, the new baby is more likely to have delayed tooth eruption as well.
Delayed or late teething is normal these days and not a cause for concern until your baby is 15 months old. If the delay is longer than 18 months, you should consult a pediatric dentist, says the American Academy of Pediatrics.
Some autistic patients who are sensory seeking might put their fingers or other objects in their mouth which is known as stimming. This can be a false indication of toothache, but it is still important to visit the dentist to double check as these habits can sometimes damage the gums or cause mouth ulcers.
Dental abnormalities are present in around 30% of patients with Gardner syndrome, and may include supernumerary teeth, compound odontomas, hypodontia, abnormal tooth morphology and impacted or unerupted teeth.
In Marfan syndrome, the major bone in the upper jaw (the maxilla) is often quite narrow, which can lead to considerable crowding of the teeth. The narrow high shape of the palate may also cause posterior crossbite— when the upper teeth align inside the lower teeth when you bite down.
Amelogenesis imperfecta is a disorder of tooth development. This condition causes teeth to be unusually small , discolored, pitted or grooved, and prone to rapid wear and breakage. Other dental abnormalities are also possible.
