Definition and incidence of congenital absent teeth

Definition of congenital absent tooth,Teeth not present at birth among the 28 permanent teeth (up to 32 if wisdom teeth are included)of the

In other words, even if all the baby teeth are present, "there are no permanent teeth to erupt beneath them".

It is not caused by disease, but is one of the formation abnormalities in the process of tooth production.

A survey published in March 2011 by the Japanese Society of Pediatric Dentistry revealed the following trends in the incidence and location of congenital absent teeth.

Incidence of congenital absent teeth (*)
- 1 in 10 children who see a pediatric dentist
Number of congenitally absent teeth occurring
- One to several bottles per person
Frequency of congenital absent teeth
- Maxillary → approx. 4.37%
- Lower jaw -> approx. 7.58%
Site of occurrence of congenital absent teeth (*)
- Right and left second bicuspids (fifth teeth counting from the front teeth)
- Right and left incisors (second teeth counting from the front)

*Wisdom teeth are not included in the survey.

Causes and Risks of Congenital Abscess Teeth

The cause of congenital absent teeth is not clearly known.

genetic factor
Nutritional deficiencies during the tooth formation stage (pregnancy)
systemic disorder
Side Effects of Medication
Radiation effects
Jaw reduction due to dietary changes, etc.

There are various theories,No clear association has been found.This is the current situation.

Therefore, congenital deficient teeth cannot be prevented.

People with congenital deficient teeth often have extra space for permanent teeth that will erupt after the baby teeth are removed.

When congenital deficient teeth cause wasted space in the permanent dentition,

Neighboring teeth fall in, resulting in poor tooth alignment and bite.
Longer teeth because they do not mesh with the upper and lower teeth
Developing a complex about their appearance due to a gap in their teeth.

Various problems arise, such as

The bite, in particular, affects everything from oral health to overall health.

When the teeth and bite are disturbed by congenital defective teeth,

Teeth are easily damaged by the force of biting.
High risk of tooth decay, gum disease, and bad breath
TMJ disorder is more likely to develop.
May affect pronunciation and smoothness of speech
Headache, stiff shoulders, etc.

Note that these risks are higher.

How to diagnose congenitally absent teeth

Congenital absent teeth are basicallyThe dentist will take x-rays to diagnose the problem.

Radiographs can be taken to see which teeth are in the gums and which are not.

Baby teeth do not fall out past the appropriate age.
Permanent teeth do not erupt after deciduous teeth are removed
Large gaps between permanent teeth
Health checkups have pointed out the number of teeth, etc.

In such cases, it is recommended that the dentist take an x-ray to see if the tooth is present.

Treatment of congenitally deficient teeth

Congenital absent teeth cannot be prevented, and there is no treatment yet to make and grow absent teeth.

Therefore, the following treatment is used in cases of congenital deficient teeth.

Long-term preservation of primary teeth
Replacing with prosthetics or implants
Alignment of teeth by orthodontics

Long-term preservation of primary teeth

If the tooth is known to be congenitally deficient before the baby tooth falls out,Avoid losing baby teeth due to decay or gum disease.

To keep baby teeth as long as possible,

Proper daily tooth brushing
Get regular dental checkups.

It is important to

Baby teeth have shorter and more brittle roots than permanent teeth and are at higher risk of decay and gum diseaseIt is.

Therefore, it is very rare for a tooth to remain for the rest of one's life, but in some cases, a baby tooth can remain until one's 20s or 30s.

Replacing missing baby teeth after the growth period has ended provides more treatment options.

If you know in advance that you have congenital deficient teeth, maintain them well and try to make your baby teeth last as long as possible.

Replacing with prosthetics or implants

If a baby tooth has fallen out,Depending on the number of congenitally absent teeth, prosthetics or implants can be used to fill gaps in the dentition.

denture
bridge
implant (esp. dental)

From among these, choose the number of teeth to be replaced, appearance, functionality, and indications.

Alignment of teeth by orthodontics

It depends on the alignment of the teeth and the bite,

Orthodontic treatment to fill the space left by congenitally absent teeth
Align and bite teeth using tooth space created by congenital defective teeth.

This can restore appearance and functionality.

If a case requires tooth extraction to make room for the teeth, the presence of congenital deficient teeth also creates the advantage of reducing the number of teeth to be extracted.

Orthodontic treatment is basically self-funded, but if there are six abnormal congenital missing teeth, orthodontic treatment may be covered by insurance.

If you have 6 or more congenitally absent teeth, see a dentist who can calculate the orthodontic diagnostic fee.
