Removal of plaque should start when the first milk teeth erupt. It is very important to do the most basic oral health care in the first year after baby is born. The main oral disease in infancy and early childhood is tooth decay, which is mainly caused by plaque.

The doctor will provide health counseling for your baby’s feeding habits, pointing out which poor feeding habits may lead to infant and toddler caries, and will also tell you the healthy and scientific feeding and diet. It is clinically found that most of the infants and toddlers who visit the clinic for dental caries have poor feeding habits.

After two years old, children should brush their own teeth, master the brushing method and brush their teeth effectively, parents had better do the brushing and rinsing after breakfast and dinner together with children. 6 years old children’s milk teeth start to fall off and permanent teeth gradually erupt, at this time, pain, red and swollen gums, discomfort and other symptoms can occur, and should be examined and treated by doctors in time to protect the newly erupted permanent teeth. 7 guidelines for taking care of teething babies 1.

If you put your thumb between the upper and lower front teeth that are erupting when you suck your fingers, it will block the normal eruption of the front teeth. 2. Licking the tongue: The most common problem during tooth replacement is that children often lick their loose baby teeth or newly grown permanent teeth with their tongues, thus forming the bad habit of spitting out or sticking out their tongues. The tongue often forms a partial opening between the upper and lower teeth, and gaps will appear between the teeth. 3, bite the lips: If you often bite the upper lip may cause the front teeth to recoil and the lower jaw to protrude forward. Biting the lower lip will cause the upper front teeth to protrude, the lower jaw to recede, the upper lip will become thick and short, open, and the teeth will be exposed. 4, lateral chewing: children are prone to lateral chewing habits in the later stages of milk teeth development, because the normal chewing function of one side of the teeth is affected by the loss of milk teeth, so they can only chew with the other side. This will cause the asymmetry of the development of the left and right side of the face, and the side that does not chew often is more likely to accumulate tartar because of the lack of food scrubbing, resulting in dental caries and other periodontal diseases. 5, bite things: many children like to chew finger nails or bite the corner of clothes, cuffs, quilt corner, pillow corner and sucking pacifier, etc., because when biting these objects are generally fixed in one part of the teeth, so it is easy to form a small local open deformity of teeth. 7, bad sleep habits: some babies are used to sleeping elbows, palms, fists and other pillows in the bottom of one side of the face, or like to often use their hands to hold one side of the cheek, these habits have an impact on the normal development of the child’s jaw and facial symmetry. 8, eat sugar before going to bed: sugar in the metabolic process of bacteria constantly produce lactic acid, corrosion of teeth to form cavities. When sleeping at night, seldom drink water, most of the organs of human body also rest, saliva secretion is reduced, and eating sugar before going to bed is very easy to occur dental caries. 9, picking teeth: If children form the habit of picking teeth, the gap between teeth will become wider slowly and food will be easily embedded in the gap. In addition, if the toothpick used for flossing is not hygienic, bacteria will enter after the mucous membrane of gums is broken when flossing, and infection may be formed. 10, random medication: tetracycline drugs taken after 4 months of pregnancy until the child is 7 years old will cause the teeth to become black in color and the surface of the teeth to be defective and uneven. Anti-epileptic drugs, calcium channel blocker class of antihypertensive drugs, immunosuppressants, long-term use is likely to cause gum hyperplasia. 11, brushing too hard: brushing too hard will cause excessive wear of the weak part between enamel and dentin on the tooth surface, forming wedge-shaped defects, causing tooth allergy, secondary caries, and even pulp exposure or gum damage and atrophy. 12, disease damage teeth: measles, chicken pox, scarlet fever and other infectious diseases, so that the development of the tissue forming the teeth is damaged, affecting the shape of the teeth in the future; indigestion, gastroenteritis, tuberculosis, poliomyelitis and other diseases, seriously damage the nutritional status of the body, hindering the growth and development of the upper and lower jaws, causing malocclusion of the teeth and bones; rickets easily cause malocclusion of the jaws.
