 Below we will introduce the expert version of the order in which baby teeth erupt, as well as brushing precautions, in order to say goodbye to the misinformation from "hearing from friends." This will take approximately two to three minutes of your time to browse. Thank you for reading.

The above is all the content of "90% of people do not brush their teeth correctly, it doesn't matter, I will teach you!" Thank you for reading. If you have any other questions, please feel free to consult our professional doctors.      

1. Sequence of eruption of children's teeth and individual differences.


A person will have two types of teeth throughout their life: deciduous teeth and permanent teeth. Normal deciduous teeth consist of 20 teeth, while permanent teeth consist of 28-32 teeth, except for cases of congenital absence or supernumerary teeth. 

Chronological order.



Normally, babies will start teething their first primary teeth around the 6th to 10th month after birth. The first teeth typically emerge symmetrically from the lower front teeth, followed by the two lateral incisors, canines, and molars. Usually, by around 2.5 to 3 years old, all 20 primary teeth will have erupted.



Around the age of 6, permanent teeth will gradually start to grow out. Some children first grow their first molar teeth (first permanent molars), while others start with the front teeth of the lower jaw to replace the baby teeth. This is all normal. The process of tooth replacement will last until about 12-14 years old, when all 28 teeth will be in place. 

PS: The first permanent molars are commonly referred to as "six-year molars" because they emerge around the age of 6. There is one on each side of the upper and lower jaws, and they are also the first permanent teeth that babies grow.




Individual Differences

The time for a baby to start teething usually begins from the 6th month after birth until all 20 primary teeth are erupted by 2.5 years old. However, some babies start teething as early as 4 months old, while others may not have their first tooth appear until 13 months old.

These differences may be related to genetic factors, gender, birth weight, and environmental factors such as temperature, nutrition, and disease.

Generally, female babies develop teeth earlier than male babies, and babies with higher birth weights tend to start teething earlier. Children with higher height and weight tend to develop teeth earlier than those with poor nutrition and lower height and weight.

Children in colder regions tend to have later tooth eruption compared to those in warmer regions.

These differences in teething time are normal and acceptable. However, if a baby has not yet erupted their first tooth by the age of 1 year old, it is considered delayed eruption and needs to be investigated for possible causes, including rickets, hypothyroidism, and nutritional deficiencies.

Common accompanying phenomena during teething include increased drooling



When teeth erupt, they stimulate the trigeminal nerve, which leads to an increase in saliva secretion. However, since young children do not yet have the habit of swallowing large amounts of saliva and their mouths are shallow, saliva often flows out of their mouths, causing what is called "physiological drooling".

Therefore, it is normal for babies to drool during teething, and there is no need to worry. This phenomenon will naturally disappear as the child grows older.

It should be noted that saliva has a certain stimulating effect on the skin, so parents need to use a soft cloth to wipe away the saliva in a timely manner to prevent infection.



Gum itchiness

Babies may feel some swelling, pain, and even skin cracking on the gums where the little teeth are about to emerge. This may lead to symptoms such as crying, irritability, and restlessness.

Parents can buy some teething toys or chew sticks for the baby to bite on, which can not only divert their attention and relieve discomfort, but also help train their chewing ability


During teething, children may feel uncomfortable and refuse to eat food that requires chewing or is warm.

If it is confirmed that the child is not sick or refusing to eat due to other factors, but because of discomfort caused by teething, do not force them to eat. Instead, prepare some nutritious and soft foods that are cold to help soothe their discomfort.

3. Care during teething and introduction of complementary foods.


Did you know that the way to clean a baby's mouth varies according to their age? This is especially important when the baby's first teeth start to emerge.


Examining the oral cavity of a newborn baby.


After birth, you can check your baby's mouth. A very small number of babies already have teeth at birth. You can gently touch the gums with a clean finger to feel if the baby has teeth, whether there are protrusions or slight inflammation of the gum line.


Regularly check your baby's teething progress. Every baby's teeth come in at a different pace, with some taking weeks to fully emerge and others sprouting two teeth over a weekend. Check your baby's gums weekly to ensure that you can catch new teeth as soon as they appear, and start brushing them.




Before your baby's deciduous teeth erupt, you should start daily oral hygiene care. Gently wipe your baby's gums with a soft, damp cloth wrapped around your finger to get rid of bacteria on the gums.

Starting at two months old, you can clean your baby's gums at least once a day. If you feel the need, you can also increase the frequency of cleaning. But be careful not to over-clean, as this can stimulate your baby's gums, leading to gum sensitivity or pain.


Cleaning the first baby tooth

Don't forget to clean your baby's tongue coating every time you clean their teeth, as bacteria can accumulate there.

"Start using the toothbrush."


Once the baby has grown a few teeth, you can choose a soft baby toothbrush for them, especially when the molars have erupted, the tool for brushing teeth should be changed from gauze to a toothbrush. The bristles should be very soft and no more than three rows. A one-year-old baby should also use a toothbrush.

At the beginning of brushing, do not use toothpaste, just use warm water. The purpose of brushing the baby's teeth at this stage is to get them used to the tool for brushing teeth. Adding toothpaste at this stage may make the baby uncomfortable and refuse to use the toothbrush.

If the baby shows an interest in brushing their teeth, you can encourage them to help you. You can let the baby hold the toothbrush handle while you brush their teeth. Once they are used to it, you can let them brush their teeth by themselves, but of course, you need to supervise them and brush their teeth again after they finish brushing by themselves.

If the baby initially refuses to use the toothbrush, you can brush their teeth once a day. As they gradually accept it, you can gradually increase the frequency of brushing until they can brush their teeth after every meal.

Tell the baby how to brush their teeth. In our minds, the "standard action" for brushing teeth is to brush back and forth, or in small circular motions, right? Actually, it doesn't matter how the toothbrush moves, the most important thing is to thoroughly brush all sides of the teeth, up and down and inside and out.

It's important to note that children may only brush the teeth they can see and often overlook the teeth they can't see. In this case, you can play a game with them to "find the hidden teeth." And don't forget to clean the tongue coating.

"Add toothpaste."


"Start by using natural swallowable toothpaste (usually with a finger toothbrush) for the baby, which is safer for babies who can't spit it out. Such cleaning tools can be used until the age of 3."



"As the baby grows a little older, you can add a small amount of toothpaste for them. Be careful not to use too much toothpaste, as only a pea-sized amount is needed."




Consult your doctor on how to use fluoride toothpaste for your baby. If you decide to use fluoride toothpaste, reduce the amount of toothpaste to a rice grain size at the beginning to avoid the baby ingesting too much fluoride.

When the baby is 3 years old and can spit out water, the amount of fluoride toothpaste can be increased to a pea-sized amount.

If the baby has not learned to hold and spit out water, remember to give them water to drink after brushing their teeth. This can dilute the toothpaste swallowed by the baby, especially if it contains fluoride. Encourage the baby to slightly open their mouth while brushing to allow any remaining toothpaste to flow out.


Encourage the baby to brush their teeth themselves.


Encourage the baby to brush their own teeth when they are capable. However, it is important to control the brushing time and prevent the baby from becoming bored or losing interest. A brushing time of 2 minutes is appropriate for children.



Choosing a cartoon character toothbrush that your baby loves can encourage them to brush their teeth. 

You can also create cute rhymes, play brushing games with your baby, count the teeth that have been brushed, and have them brush their teeth in front of a mirror to increase their enjoyment of brushing.



Brush your teeth together with your baby and tell them what you're doing, so they can follow along with you.



Before babies learn how to rinse and spit, remember to give them water to drink after brushing their teeth. Show them how to spit out the water.



Teach your baby some oral care knowledge that they need to master, such as keeping the toothbrush clean.

The American Academy of Pediatrics recommends rinsing the toothbrush with water to remove any remaining toothpaste and tiny food particles, and storing the toothbrush with the bristles facing up to air dry naturally. Since babies love to play with water, it should be easy to get them to rinse their toothbrush.

Whenever your baby tries hard to learn brushing teeth, you should give them some special rewards. 

For example, you can read them a book they love, play with their favorite toys, or participate in an activity they enjoy. Rewards can be diverse, see which one can best motivate your little one.

▎Introduction of complementary feeding during the weaning period.

    When a baby's first teeth emerge, they move away from the group of toothless babies. At this stage, babies love to put anything they can get their hands on in their mouths to chew on. Moms can try to give babies some semi-solid foods, such as mashed potatoes, egg yolk puree, oatmeal porridge, etc., to let babies experience the transition from liquid to paste-like food. Slightly thickened complementary foods can make babies aware that their food is beginning to change, laying the foundation for them to exercise their teeth for chewing solid foods in the future.



After the age of 3, food should not be too finely processed.

Parents often notice that their child's previously straight baby teeth become crooked after the permanent teeth come in. This is because the permanent teeth are much larger than the baby teeth, and if the child's jawbone does not receive sufficient stimulation between ages 3-5, the jawbone may not develop enough space for the teeth, causing them to grow in crooked.

Chewing food can promote the growth and development of baby teeth roots and facilitate natural absorption and shedding. Overly processed foods can lead to decreased chewing function in children's teeth and poor jawbone development. Therefore, parents should encourage their children to eat more chewy foods such as celery, peanuts, apples, sugarcane, and other fibrous fruits and vegetables.
