Why does a three-month-old baby bite his lower lip?

Some babies have abnormal physical phenomena, so they need to pay attention to timely examinations and treatments to ensure the health of the baby and avoid situations where the baby's safety is affected by physical problems. So why do three-month-old babies bite their lower lips? Let me introduce this issue to you below.

Baby beauty killer 1: biting lips

It is very common for babies to bite their lower lips and suck, which are voluntary movements of children. Generally speaking, the sucking of a 3-4 month old baby is likely due to the fact that the sucking instinct is not satisfied; after 6-8 months, when the child lacks love and attention, he or she will develop habits such as biting his or her lips when seeking comfort.

Biting the lower lip: lips become thicker

Under normal circumstances, the teeth are located between the lips and tongue, and the pressure of the tongue muscles and lip and cheek muscles is balanced inside and outside the teeth. If a child has the habit of biting his lips, this internal and external balance will be disrupted, resulting in a series of deformities.

Biting the lower lip will put pressure on the lingual side of the upper front teeth and the labial side of the lower front teeth (referring to the upper and lower incisors). This abnormal pressure will push the upper incisors to gradually tilt forward and force the lower incisors to move backward. As a result, the upper incisors are over-protruding, with gaps between the teeth; the lower incisors are crowded and uneven, with a large front-to-back distance between the upper and lower incisors.

It is not easy to bite off food when chewing, and the upper lip will be pushed outward and become thicker by the protruding upper teeth, making it difficult to close it with the lower lip, forming a "teeth-exposed, lips-open" face, which affects both the function of the teeth and the beauty.

Biting the upper lip: Overbite

Biting the upper lip is just the opposite of the above situation, which will cause the upper incisors to be inward-convex, crowded, sparse lower incisors and protrusion of the mandible. In severe cases, the front teeth may even be misaligned, commonly known as "underbite" or "underbite", making the entire face appear sunken.

(√) Correction method

1. When a child develops the habit of biting his lips, parents should remind and correct him at any time to help him get rid of the bad habit of biting his lips.

2. When a child bites his lips, you should reduce his tension and anxiety. For example, when watching cartoons, if there are scenes that make the child nervous, you should take the initiative to comfort the child.

Baby Beauty Killer 2: Mouth Breathing

Some babies have to breathe through their mouths due to medical reasons, while others simply develop a bad habit. Medically proven, long-term mouth breathing can easily induce oral and respiratory diseases, and can also affect the normal development of the face, making it easier for you to grow uglier.

The above is my opinion on this issue. If the baby has the above problems, then the baby needs to pay attention to timely examination and treatment, so as to ensure the baby’s safety and avoid endangering the baby’s safety due to the above problems. Finally, I wish the baby can get rid of this bad habit.
