Delayed eruption of primary teeth

People will have teeth erupt twice in their lifetime. The first teeth are called deciduous teeth, and the second teeth are permanent teeth. Deciduous teeth will slowly fall out after the child enters the stage of five or six years old, and will be replaced by permanent teeth by the time of puberty. Permanent teeth are stronger and sharper than deciduous teeth. Both deciduous teeth and permanent teeth are very important for our oral hygiene. So what should we do if the deciduous teeth are delayed?

What to do if the eruption of deciduous teeth is delayed

1. Generally, babies grow their first deciduous tooth at around 6 months old. Due to individual differences among children, some grow teeth early and some grow teeth late. Generally, the difference between early and late is about half a year, which is within the normal physiological range. In other words, it is normal for the first tooth to erupt within 1 year old. However, if a child still has no teeth after the age of one, it means that the deciduous teeth have indeed erupted too late and the child should be consulted by a doctor.

2. The growth and development of deciduous teeth is related to the mother's health during pregnancy. Deciduous teeth begin to develop when the embryo is two months old. The growth and development of deciduous teeth is a long process. Nutritional intake during pregnancy determines the growth and development of deciduous teeth, the nutrition and overall health of the baby after birth, and also directly affects the growth, calcification and eruption of deciduous teeth.

3. Therefore, if the mother is healthy during pregnancy, the baby is well-nourished, and grows and develops normally, the eruption of deciduous teeth will definitely be normal. If the deciduous teeth erupt too late, the first thing to do is to rule out congenital edentulism and swollen and painful gums.

Eruption time of deciduous teeth

1. Most babies' deciduous teeth erupt at 7-8 months; those that have not erupted at 12 months are considered to have delayed tooth eruption; all deciduous teeth will erupt at 2-2.5 years old. There are 20 deciduous teeth in total.

2. Generally, the mandibular teeth erupt before the maxillary teeth, and the eruption sequence is from front to back.

3. The eruption time of deciduous teeth varies greatly from person to person, which is related to genetics, endocrine system and food characteristics. Generally speaking, babies start to have deciduous teeth at 6-8 months old. The earliest baby may start to have teeth at 4 months old, and the latest may be 10-12 months old. Babies usually have 8 deciduous teeth at the age of 1 year.

4. If the child is over 1 year old or has not grown the first deciduous tooth for a long time, the influence of systemic diseases should be considered. Such as rickets, cretinism, extreme nutritional deficiencies, etc. Children with more severe malnutrition, rickets, hypothyroidism, trisomy 21 syndrome, etc. may have delayed tooth eruption and poor tooth quality.

When a child's deciduous teeth begin to erupt, attention should be paid to supplementing their nutrition, and care should be taken not to feed the child hard food at this time, as this may damage the child's erupting teeth and cause the child's teeth to be unhealthy. If there are problems with the timing of tooth eruption in children, timely treatment is necessary to reduce the possibility of disease. It is best to go to the hospital for examination.
