The time and number of baby’s teething, the time of tooth replacement.
1, the time of teething: 6 to 9 months when the milk teeth begin to erupt, but may be early to 3 or 4 months, or delayed to 11 or 12 months before teething, usually the front teeth will have a difference of 6 months before and after, the difference of the back teeth even up to 1 year;
2.Number of milk teeth: 20;
3, when to start the tooth replacement: 6-7 years old milk teeth began to fall off for permanent teeth, 17-30 years old permanent teeth, a total of 28-32. 6 years old is about 24.
When the baby starts to grow the first tooth, parents should start to learn how to teach the baby how to brush teeth correctly
Because brushing not only can clean teeth and remove plaque, but also can play the role of massaging gums and promoting blood back to the gum circle, which can improve the supply of local nutrition and oxygen to facilitate tissue metabolism and improve the resistance of gums to diseases. Therefore, brushing is a good and effective way to maintain oral cleanliness and prevent dental caries and periodontal disease.
First of all, parents need to know is that how old do babies need to brush their teeth?
In principle, it is said that babies should start brushing their teeth after they have teeth.
Because brushing not only can clean teeth and remove plaque, but also can play the role of massaging gums and promoting gum blood back to the circle, which can improve the supply of local nutrition and oxygen to facilitate tissue metabolism and improve gums’ resistance to disease. Therefore, brushing is a good and effective way to maintain oral cleanliness and prevent dental caries and periodontal disease.
Initially, because there are only a few teeth in front and the eruption is not complete. It is not convenient to use toothbrush, so it is better to use gauze dipped in salt water and scrub along the tooth surface.
When the baby has 16-20 teeth, about 2.5 years old, after all 20 milk teeth have erupted, you can gradually train to use a toothbrush at this time. Around the age of 3, children should develop the habit of brushing their teeth in the morning and evening and rinsing their mouth after meals. When your baby gets used to the habit of brushing, you need to train your baby to spit out the toothpaste. When baby can basically spit out most of the toothpaste, you can switch to anti-cavity toothpaste to better prevent the occurrence of tooth decay.
Since the fluoride content of adult toothpaste is higher than that of children’s toothpaste, children’s hands are poor and the development of hand operation function is not yet perfect, so the skill of containing rinse is not fully mastered. At this time, if adult toothpaste with high fluoride content is used, when brushing teeth, it is inevitable to swallow toothpaste with high fluoride content by mistake, and if too much fluoride is swallowed every day, it is not good for children’s healthy growth, so parents should buy special toothpaste for children with low fluoride content for preschool children.
If the child has not yet mastered the skill of containing rinse, he can start to use no toothpaste for the time being, but use the stronger tea water to brush his teeth, because the tea water also contains the elemental fluorine which has the effect of preventing caries. At the same time, parents should take care of children when they brush their teeth.
Pay attention to the dosage of toothpaste.
To prevent children from accidentally taking toothpaste residue, the American Dental Association recommends that children younger than 3 years old should only use a thin layer of toothpaste; for children between 3 and 6 years old, the amount of toothpaste used can be “upgraded” to the size of a pea, and for children over 6 years old, the amount is generally about the size of a pea each time.
The American Dental Association’s new standard specifically limits the amount of fluoride in children’s fluoride toothpaste to between 0.05% and 0.11%. It is best for children to brush their teeth under adult supervision.
In addition to proper brushing, children should also develop proper oral cleaning habits, rinse more after meals, snacks and drinks, and go to the hospital for routine oral examinations every six months.
The correct way to brush baby’s teeth.
Brushing should include 3 tooth surfaces: the inner measuring surface, the outer side, and the horizontal chewing surface. Pay special attention to cleaning the posterior molar (lingual side) and the superior molar (buccal side), as these are the areas most likely to be missed when brushing your baby’s teeth.
The following steps can teach you how to brush your baby’s teeth properly.
In addition, brushing must also adhere to the “three two system”, that is, brush 3 times a day, and focus on the one at night before going to bed; 3 sides of the teeth (cheek, tongue, bite lift side) should be brushed, and each brush should be carefully and carefully brushed for 3 minutes.
How to choose the toothbrush for infants and children.
1, the bristles should be soft and the brush head should be small so that it is easier to reach all the baby’s teeth, including the innermost teeth.
2, the brush surface is flat, and the top of the bristles are round body shaped so that they do not scratch the baby’s gums.
3, Adult toothbrushes are not suitable for young children because the brush head is too large for the baby to use comfortably and the bristles may be too hard, which will wear down the baby’s teeth and gums. Choose a special children’s toothbrush, under 1 year old baby can choose finger toothbrush.
4, choose a toothbrush with a “hard” handle, so as to maximize the exercise of muscle movement skills.
5, vertical placement of toothbrushes, and keep dry, with adjustment, can be placed in a place where the sun can shine. Make sure that the bristles of each toothbrush do not touch each other to prevent bacteria from passing from one toothbrush to another.
6. Replace your toothbrush when it becomes worn out, such as when the bristles come apart.
7. In any case, change your toothbrush at least every 4 months, and always change your toothbrush after you get sick, because old toothbrushes may harbor bacteria.
Choice of brushing water temperature.
The cold weather in autumn and winter makes babies become more reluctant to brush their teeth because of the cold water. In fact, in addition to mastering the correct method of brushing teeth, the water temperature is also very important!
If the teeth are subjected to sudden hot or cold stimulation for a long time, this not only tends to cause bleeding and spasms in the gums, but also directly affects the normal metabolism of teeth, which can lead to dental disease and shorten the life span of teeth, as well as causing dentin allergy symptoms. In addition, according to the research of Japanese medical doctors, teeth are adapted to normal metabolism at 30 – 36 degrees Celsius mouth temperature.
Therefore, both parents and babies should pay attention to the temperature of the water used for brushing teeth. Water that is too cold or too hot tends to irritate teeth, so warm water is the best choice.
Brushing training for young children can be done in three stages.
The first stage: when the baby starts to grow the first teeth, that is, from about 6 months onwards, you should “brush” the baby’s teeth. Of course, the brushing mentioned here does not use a toothbrush, but the parents use clean gauze wrapped around their index finger dipped in clean water to help the baby clean the mouth, wash away the teeth and dental bed on the attachment, this oral care method generally to last until the toddler two and a half years old, when all the milk teeth in the mouth erupted.
The second stage: from the age of two and a half years, parents should choose the toothbrush for the child to use at this age, twice a day in the morning and evening, standing behind the child, hands to teach the child to master the correct method of brushing teeth (brush method). Because children of this age have certain understanding and expression ability, as long as parents follow the instructions, from the shallow to the deep patient guidance, I believe it is not difficult for children to master the correct method of brushing teeth.
The third stage: from the age of 3, children have been through half a year of transition training, should be able to complete the toothbrushing action independently. But at this time, children are still very naughty, lack of initiative and self-consciousness, parents usually have to play a supervisory guidance role, so that children develop good oral hygiene habits, so that children have a healthy and beautiful teeth.
