Often bite your mouth and nails, will your mandible get bigger?

Biting lips will bring three major oral hazards to children.

Lead to irregular dentition

Under normal circumstances, teeth are located between lips and tongue, and the pressure of lingual muscles and labial and buccal muscles is in a balanced state inside and outside teeth, which plays a very important role in maintaining the normal arrangement of teeth and the natural shape of lips. Especially in the growth and development period of children, if children have the habit of biting their lips, this internal and external balance will be destroyed, the arrangement of teeth and the natural state of lips will be destroyed, resulting in a series of deformities.

Affect appearance and chewing function.

Biting the lower lip will press the lingual side of the upper front teeth and the labial side of the lower front teeth. This abnormal pressure will push the upper incisors to tilt forward gradually and press the lower incisors to move backward. As a result, the upper incisors are too far forward, and gaps appear between the teeth. The lower incisors are crowded; The distance between the upper and lower incisors is too large, so it is not easy to bite off food when chewing; The upper lip will also be supported by the upper teeth of the front teeth to curl outward and thicken, and it is difficult to get close to the lower lip, forming a "buck teeth" face with "teeth exposed and lips open", which will not only affect the function of teeth, but also affect the appearance.

Biting the upper lip is just the opposite of the above situation, which will cause the upper incisors to be depressed and crowded, the lower incisors to be sparse, the mandible to protrude, and even the incisors to be inverted, and the whole face will be depressed.

Forming mucinous gland cyst

Children who have the habit of biting their lips are prone to cheilitis and mucocele of their lips, in addition to the bite marks of their teeth.

As we know, there are many isolated and scattered small salivary glands under the oral mucosa, including the labial mucosa. When the ducts of these small glands are blocked by the mechanical pressure of children biting their lips, when mucus cannot be discharged, it will cause the gland wall to swell and form a blue transparent cystic tumor, which is what medical students call a mucinous gland cyst.

When it expands to a certain extent, it will burst on its own.

But the catheter is still blocked, so as long as the surface mucosa epithelium heals in a few days, once the cystic fluid accumulates, it will swell up again, and so on. It can be seen that the occurrence of mucocele is closely related to the bad habit of children biting their lower lips, and the key to prevention lies in correcting the habit of children biting their lips in time.

Parents should always remind children who have the habit of biting their lips to correct them, so as to quit the bad habit of biting their lips.

When children bite their lips, parents should keep a calm attitude, guide and educate their children patiently, meticulously and persuasively, and then teach them how to protect their teeth and lips, so that they can gradually understand the intentions of adults and learn to correct their bad habits. For more oral health problems of children, please consult hippo dentist.

For older children, parents can take the method of inducement to guide them to observe and imitate other children and keep their mouths shut.

When children have made initial corrections, they should be affirmed or praised in time. If children often bite their lips before going to bed, parents can gently open their lips and let their children fall asleep quietly, which can also encourage children to gradually correct the problem of biting their lips.
