Baby's baby teeth form while the baby is still in the mother's womb. You'll see evidence when your baby's first tooth comes in, which usually happens between 4 and 7 months old. So when do baby teeth form? And are baby teeth stem cells? The following article will help you better understand the origin of your baby's baby teeth and what baby teeth do.

1. The development of baby's baby teeth


The teeth that come in when the baby is still in the breastfeeding stage, the baby's milk teeth are about 30 months old. Baby teeth are also known as temporary teeth because baby teeth only exist with the development of the baby for the first few years of life and will gradually be replaced by adult teeth. However, baby teeth play an extremely important role in the process of eating, chewing and developing baby.
The normal baby teeth stage for a child will grow 20 primary teeth – 10 upper teeth and 10 lower teeth. Most of these teeth actually erupt and develop by the time a child is 2 and a half years old.
Usually, when babies are about 6 months old, their teeth will start to come in. The first teeth to erupt are usually the central incisors - the middle teeth, the incisors - the lower jaw. The second tooth usually grows right next to the first one: the second incisor is located in the middle of the lower jaw. The next four teeth to come in are usually the four upper front teeth. They usually begin to erupt about two months after the same tooth in the lower jaw erupts.
The second molars are usually the last of the 20 to fall out, erupting when a child is about 2 and a half years old.
The process of teething in children can also be different: Some babies get their baby teeth earlier, some later. If you have any questions about your baby's teething, talk to your dentist. They can answer specific questions from parents.
The American Academy of Pediatric Dentistry suggests that a child's first dental visit should be done before the baby is 1 year old, after the first tooth appears, and within 6 months.
Your baby's twenty baby teeth will gradually be replaced by 32 permanent teeth, also known as adult teeth. Parents can expect their child to start losing their first baby teeth by the time they are 6 years old. The first permanent teeth to erupt are usually to replace the first baby teeth to erupt: the central incisors. Usually the process of replacing a child's permanent teeth will last until the child is 12 years old, but there are children this time will last longer or end earlier.
The difference between baby teeth and permanent teeth lies in several points including:
Enamel: Enamel is the hard outer surface that protects a child's teeth from decay. The enamel that protects baby teeth is usually thinner than that of permanent teeth. Color: Baby teeth usually look whiter than permanent teeth. Many theories are due to the thinner enamel. Size: Baby teeth are usually smaller than adult permanent teeth. Shape: The anterior permanent teeth are often impacted and tend to wear down over time. Roots: The roots of baby teeth are shorter and thinner so they are easier to fall out as the child enters the age of tooth replacement.

2. What are the effects of baby teeth?


Although baby teeth do not last with the baby until the end of life and will be replaced by permanent teeth when the child is old enough, these are still indispensable teeth and have many effects on the general digestion of children. Baby:
Baby teeth play a role in helping babies digest food : After 6 months of age, mothers begin to add solid and more indigestible foods to their baby's diet, which requires children to learn how to chew to crush food before swallowing Baby teeth help permanent teeth grow more evenly: Normally, baby teeth grow up and stand on the child's jaw. After a few years, the root begins to recede and makes room for an adult tooth that will emerge in the same place as the old baby tooth. If the baby's baby tooth is damaged and has to be extracted soon, the adult tooth germ underneath has not yet grown and cannot grow in time to fill the gap, the small tooth hole is blocked and becomes hard. Grown adult teeth will have difficulty, grow more slowly and even grow out of their original position. Helps develop jawbone: Thanks to baby teeth, babies can chew and bite food. These activities help your baby's jaw develop normally. Support the child's pronunciation: If the baby teeth are damaged prematurely and have to be extracted, this will make it difficult for the child to pronounce words or slurred speech.

3. Are baby teeth stem cells and what are their effects?


As one of the cells that develop from the embryonic stage, baby teeth are considered the body's stem cells. According to dental experts, stem cells from tooth pulp have the outstanding advantage that each person has 20 baby teeth and can lose them naturally without too much intervention from medical professionals or specialists. dental family. Each baby tooth after 3 weeks of culture in the right environment can produce up to 10 million cells.
The number of published research projects applying dental pulp stem cells is now more than 1000. These studies prove that pulp stem cells have a special ability to differentiate into cells. specialized for the treatment of dental diseases, type 1 diabetes, metabolic cardiovascular disease, liver, muscle, bone, nerve, corneal diseases and wound healing on the skin.
Especially, compared with other types of stem cells such as stem cells from bone marrow, adipose tissue..., stem cells from tooth pulp have the most superior ability to differentiate into neural stem cells.
The process of taking stem cells from baby teeth is done when the baby is taken to the dentist. When taking teeth, the dentist will have to carefully check and make sure there is a root before the stem cells can be cultured.
After being taken by the dentist, the baby teeth are stored in a specialized environment to be cultured. If properly preserved, from the time the tooth is removed to the time it is sent to the laboratory, it can be left overnight.
After the teeth are brought to the laboratory, they will be isolated, cultured, determined for cell viability and proliferation. For the teeth that can be cultured, the cells will be placed in a bank for cryopreservation in liquid nitrogen.
The cost of storing dental pulp stem cells in the world currently fluctuates depending on banks. The most expensive cost is $ 2,000 for the steps of obtaining, isolating, and identifying stem cells. After that, the annual cost of preserving samples is in the range of $120.

4. Taking care of baby teeth


Some parents may feel that taking care of baby (primary) teeth is not as important as taking care of adult (permanent) teeth, simply because baby teeth will eventually fall out as the child gets older However Baby teeth are very important. They allow children to chew food and speak properly, and they leave space in the gum tissue for future adult teeth.
Cavities are preventable. Good oral hygiene habits and a healthy diet, established early on will greatly reduce the risk of developing tooth decay. Tips for taking care of baby teeth and developing good oral hygiene habits include:
From birth: Clean your baby's mouth and gums using a soft cloth to wipe. Brush teeth at least twice a day with a soft toothbrush and water 12 months: First dental visit 18 months: Add a pea-sized amount of low fluoride toothpaste or toothpaste children's teeth into the brush and encourage them to spit out the toothpaste (do not swallow or rinse) Two and a half years: Start flossing between any teeth that touch 4-5 years old: Start teaching children Self-brushing at age Six: Switch to adult toothpaste and continue to encourage your child to spit it out and not rinse. Start teaching your child to floss on their own Eight years old: Allow your child to brush and floss without supervision. Continue to have regular dental check-ups. Decayed baby teeth require dental treatment and in some cases, specialist treatment in a hospital with general anesthesia. If unfortunately, decayed baby teeth can lead to mouth sores, tooth abscesses, and problems with surrounding teeth. Severely decayed baby teeth can affect eating, sleeping, and slow growth. If a baby molar is lost early (due to severe decay), the baby teeth next to the missing tooth can drift into the space and create space problems for the adult tooth as it erupts.
From about 6 years old, baby teeth start to 'loose' and fall out to make room for adult teeth. It is completely normal for a child to lose their first tooth earlier or later than the age of six. Girls often lose teeth earlier than boys. The first tooth to fall out is usually located in front of the lower jaw. Losing baby teeth can be uncomfortable and painful for young children. Suggestions for parents include:
Reassure your child that losing baby teeth is a natural process and that new adult teeth will come in in their rightful place. Apply cold or an over-the-counter anti-inflammatory or pain reliever to help relieve a loose toothache. Talk to your dentist for recommendations on the right medication for your baby. Offer reassurance - it's normal for gums to soften and bleed a little, although some children find it uncomfortable or not uncomfortable when a tooth is lost. Use Tooth Fairy. This method pops up in many western countries and has been around for a long time for a good reason. If the idea of ​​getting a coin in exchange for a tooth calms your child's idea of ​​losing a tooth, then go ahead and use it.

Permanent teeth are also known as adult teeth or secondary teeth. Permanent teeth begin to grow in the jaw at birth and continue after the child is born. By the age of 21, the average person has 32 permanent teeth, including 16 in the upper jaw and 16 in the lower jaw. (In some cases, the third molars - commonly known as wisdom teeth - do not erupt or do not erupt. Therefore, a set of 28 permanent teeth is also considered normal.)
At around age 6, the first permanent molars erupt. These four molars (two each) grow behind the child's existing primary teeth. Other permanent teeth, such as incisors, canines, and premolars, grow into the gaps in the gums left by the falling primary teeth.
Like primary teeth, the timing of permanent teeth eruption varies from one child to the next. In general, the eruption order and time of eruption of each type of permanent teeth are:
First molars - six to seven years Central incisors - six to eight years Lateral incisors - seven to eight years canines - ages nine to 13 Premolars - from nine to 13 years Second molars - ages 11 to 13 Third molars (wisdom teeth) - ages 17 to 21, if any. Mouth guards help protect teeth and limit oral trauma, especially when playing and practicing contact sports. All children who play contact sports must wear a mouth guard, even elementary school age children. The professional mouth guard is comfortably fitted, allows speech and does not restrict the baby's breathing ability. Baby teeth, also known as primary teeth or baby teeth, are the first teeth of every human being. They begin to develop during the embryonic stage and begin to sprout through the gums about 6 months after birth. There are a total of 20 baby teeth and most of these develop by the time a child is 2 and a half years old. Baby teeth begin to fall out around the age of 6 and are replaced by 32 adult permanent teeth.
