Bite in Children: What does your child's teeth crooked?

Any sensible and loving mother seeks to give your child the best.We do not always pay attention to the pleasant and touching detail the behavior of the child, that each of us associated with childhood: a finger or a pacifier in his mouth, fist under the cheek during sleep zakushennaya lower lip at the time of important lessons, supporting the head arm at his desk in theschool.But it is such "invisible" senior habits, recurring regularly, can greatly affect the developing maxillofacial unit at the child.

upper jaw begins to develop in the middle of the 2nd month of fetal development, a separate part of it - incisive bone - consist of two parts, intergrows 5th month of embryonic development.It is shaping the future of the hard palate.The lower jaw is also composed of two independent parts.At birth they are associated with connective tissue, bone joint is formed only on the 3rd month of the baby and fully completed by the end of the first teeth.Already in the first weeks of fetal development formed the rudiments of milk teeth.That is what would have dimensions of the jaw and teeth, to a large extent dependent on the anatomical structural features of those of both parents.Heredity in this case, comes to the fore.The similarity of the structure, size and shape of certain bones and skull as a whole and then defines the external similarity of the child and his mom or dad.The eruption of primary teeth occurs from the 6th to the 13th month.But at the same time is beginning to shape the future of the child's permanent teeth.So at the age of 1 year old kid can not only boast about 2-4 milk teeth, his jaw bones at this point, "hidden" developing the rudiments of the permanent incisors, canines, and even first molars (6th teeth which erupted only after 5 years).The emergence of permanent teeth in children usually goes in this order: 6 and 1, 2, 4, 3 (Fang), 5, 7.

It should be noted that the formation of each tooth continues after the eruption, t. To. The root develops for another 2.5-3 years.Therefore, if parents notice what seemed permanent tooth grows crooked, is tilted, rotated, during the subsequent few years, it is easy to act even finger massage at home.This is especially true for single rooted anterior teeth.Thus, the permanent dentition (between teeth) is fully formed to 14-15 years.If wisdom teeth erupt later and they did not have enough space in the jaw can be a turn or offset of the teeth out of the entire series (eg, canine).

Of course, only a doctor can properly assess the child's bite, make a diagnosis and prescribe treatment.But parents can identify some signs themselves.Here are some of them:

Besides heredity, metabolic characteristics, chronic disease that can still influence the growth and development of the jaw bones and teeth:

Many parents do not pay attention to such trifles.The child is constantly sucking finger, then he took the pencil in the classroom at school.Some researchers say communication habits of sucking something with a probability of addicted adult smoking in the future.Who knows, maybe this is the truth?Normally, to 2 years of sucking reflex fades, but in some cases it may be delayed for long.It was at this age need to wean the baby sucking the nipple and to ensure adequate nutrition, which includes solid food, the ability to chew and bite her pieces.When a child is constantly sucking a pacifier or finger muscles of the cheeks and tongue cut and put pressure on the lateral portions of dentition, forcing them to move inside.This can cause narrowing of the upper and lower jaws, the appearance of a lack of space, the inclination of the teeth in, slide out the front teeth out or tilt.Furthermore, this can cause a diastema (the gap between the front teeth).If you wean a child from pacifier sucking hard, there is a special silicone plate for such a case that looks like a pacifier and occurred at the same time corrects malocclusion.You can also use special nozzles on the finger and bracelets that do not allow a child sucking her thumb.


cutting pressure of the lower lip, which the child sucks or bites between teeth, causes displacement of the lower front teeth in the direction of the language, their slope, crowded position.

In such cases, the possibility of vertical anomalies of dentition, the movement of individual teeth.The most common forms open bite, in which the anterior teeth are not closed, and between them is always a gap.Chance of inclination of the front teeth outward appearance of diastema, the nomination of the upper teeth down and bottom up, turn them around an axis displacement of posterior teeth and a violation of their closure, the development of cross-bite (when closing the jaws on the one hand from the outside are the upper lateral teeth, and withthe other - the lower).To eliminate this habit also use special vestibular plate with a wire stopper for the language.


In these situations increases the probability of formation of improper teeth clamp, rotation or displacement of individual teeth, the expansion of dentition, displacement of the mandible to the side and the appearance of facial asymmetry, the development of cross-bite.

usually caused by the development of its difficult passage of air through the nasal passages.This may be associated with chronic rhinitis, the presence of adenoid growths, deviated septum, and so on. D. Often this method of breathing becomes a habit and, after the removal of obstacles.At the time the balance is broken mouth breathing muscles of the mouth, changed the position of language, and his teeth and did not merge.As a result, it may develop mesial or distal position of posterior teeth (their displacement forward or backward), open bite, the occurrence of diastema.To eliminate habits breathe through the nose using preortodonticheskie trainers that are at least 1 hour a day and at bedtime.There is a training circular muscles of the mouth and the habit of proper breathing.


participate in the process of swallowing tongue, cheeks, floor of the mouth muscles, soft palate, pharynx.Normally, swallowing occurs in serried teeth and lips.The tip of the tongue rests on the anterior part of the hard palate in the mouth creates a low pressure.Newborn swallowing occurs when the jaws of open and tongue at this point rests on the cheeks and lips.Such a way of swallowing usually varies by 8-10 months of age, but can remain for a lifetime.As a result, may develop an open bite, distookklyuziya (offset mandible ago), reconfiguration and reduction of the lower third of the face.


Often this habit is developed displacement of the mandible to the side or forward (meziookklyuziya).Externally it is characterized by projecting forward the chin, upper lip retraction, concave profile.Between the teeth can be formed a gap, and the lower front teeth go outside at the top, breaking the process of biting and chewing.If the jaw is displaced away, cross-bite is formed (on the one hand externally located upper lateral teeth on the other - the lower clamping jaw at the time).To resolve this habit is necessary to watch a correct posture of the child, give him enough exercise for the full formation of the muscular system and skeleton.During sleep, use a special trainer (silicone pad in the form of CVR), which teaches the jaws and dentition correct position.

After a bit of milk or permanent teeth appeared above the gum, development of the root.During this period, it may be quite effective massage gums and teeth properly located.Mom fingers like "pull" the crown of the tooth, moving from the edge of the gums to the tooth, providing moderate pressure in the right direction.With 3 years can be purchased vestibular plate (standard or personalized) for weaning from the habit of thumb sucking, tongue, lip.It is necessary to monitor the situation of the baby's head while breastfeeding or sleeping, his posture.With gymnastics coach orbicularis oris muscle (eg, pulling a tube sponge), the language (for example, to get the tip of the nose or chin).There is a lot of literature describing such exercises.Parents should ensure that all the conditions for the proper formation of the child such important functions as breathing, swallowing and speech.Timely detection of violations can much easier future treatment or even prevent the development of malocclusion.
