As a professional dentist, I have been asked more and more frequently about my baby’s oral health. Here is a compilation of the questions I am often asked, hoping to help all confused mothers and babies. 1.When should babies start brushing their teeth? Technically speaking, you should brush your baby’s teeth as soon as the first tooth comes in. When your baby is too young, parents can use a finger toothbrush dipped in water to clean your baby’s teeth. When your baby has certain imitation ability and the swallowing function is mature and won’t swallow toothpaste by mistake, you can buy your baby a children’s toothbrush and children’s toothpaste with low fluoride and try to let your baby brush his teeth by himself. For babies who resist brushing, parents should be more patient, for example, buy some toothbrushes with baby’s favorite patterns to stimulate baby’s interest in imitating adults to brush their teeth. 2.How about the black stains on baby’s teeth that cannot be brushed off even after brushing? At this time, parents should take the baby to the professional dental hospital for examination to confirm whether the black discoloration is carious or not, if it is carious, then we should follow the doctor’s advice to carry out the necessary treatment, if it is not carious, then we should pay attention to maintain the baby’s oral hygiene. The appearance of pigmentation may be due to the baby’s oral hygiene on the one hand, and on the other hand, it may be because the surface of baby’s teeth is not smooth by nature and easy to deposit pigmentation, so some babies will still have pigmentation even if they brush their teeth very carefully, it is enough to maintain the baby’s dental health at this time, because the baby’s permanent teeth will start to replace the milk teeth after 6 years old. 3.Does it affect my baby’s dental health if he likes to suck on a pacifier? Strictly speaking, babies should stop sucking on pacifiers when their milk teeth have basically erupted around the age of two, as the prolonged sucking force will affect the shape of the dental arch and even lead to the emergence of whistling teeth; and preferring to eat pacifiers while lying on their backs may lead to the emergence of “encephalitis”. 4. Does the mother’s breastfeeding position have an impact on the baby’s dental health? When it comes to the pacifier habit of lying on your back, I would like to remind young mothers that the feeding position of letting the baby lie on her back or letting the baby fall asleep with the bottle directly is not right, which may also lead to the baby’s appearance of “Diastema”. The correct way to breastfeed is to hold the baby at an angle of about forty-five degrees to the floor. The correct way to feed a baby is to hold the baby at an angle of about 45 degrees to the ground. We do see many babies with “encephalocele” not as a bony problem, but as a result of incorrect parental breastfeeding, which can be lifted by simple orthodontics in mild cases, but may require more complex treatment if the degree is heavy. 5.What should I do if my baby’s teeth are very sparse? If your baby has sparse teeth during the period of teething or tooth replacement, parents need not worry too much and do not need to rush to correct them because it is normal to have certain gaps during this period and permanent teeth will occupy these gaps during the eruption process. If there are still gaps after the teeth have been replaced, you should take your baby to a professional dental hospital for consultation and follow the advice of a professional doctor to choose the best time for treatment and the most suitable treatment plan. 6.What should I do if my baby has gaps in the upper incisors? If there is only a simple gap in the upper incisors, there is no need to rush to orthodontic treatment during the period of teething and tooth replacement; if the gap is caused by a low upper lip tie, you should listen to the advice of a professional dentist and choose the right time for treatment. 7, all orthodontic treatment should be carried out after the replacement of teeth? Not so, some orthodontic treatment must be carried out at the right time, and missing the best time may lead to more complex orthodontic treatment in the future at a greater cost. For example, the orthodontic treatment of the “grounded sky” can be carried out at the age of about four years old according to the baby’s specific situation; small chin deformity has an opportunity for orthodontic treatment in the early growth spurt, and missing this time may lead to the need for surgery in adulthood. These need to be judged by professional orthodontists, so parents are advised to regularly take their children to professional dental hospitals for oral examinations, for early detection and prevention and treatment. The above suggestions may only partially answer the questions of some parents, then, to give more targeted advice for each child, parents need to care more about their children’s oral health, and regularly take their children to professional dental hospitals for professional examination.
