Patient's question:
Age, recently there has been, often until it breaks the skin, other such as diet, deep sleep, etc. everything is normal! Hello doctor, is it caused by a lack of certain elements, or other reasons?! Previous treatment history...Doctor's answer:
Encountering some children with small blisters, the size of soybeans, on their lower lips, which are very soft and appear semi-transparent upon close inspection! When they rupture, they secrete a sticky liquid, and scabs form within a few days before new ones grow. This is what is known in medicine as a "mucocele."Advice: We know that in the human mouth, apart from the three pairs of salivary glands (parotid, submandibular, and sublingual glands), numerous small, marginal, and concentrated salivary glands are arranged beneath the oral mucosa, including the labial mucosa. Mucoceles are caused by the blockage of the ducts of these small glands, preventing saliva from being secreted.
Children's lips are not only delicate but also rich in blood vessels and nerves. Some children often have the habit of constantly rubbing or chewing their upper front teeth against their lips, which can easily cause mechanical compression of the small glands beneath the labial mucosa, leading to blockage. As a result, saliva cannot be secreted, causing the gland walls to gradually swell. The gland tissue atrophies, forming a translucent, bluish cystic swelling. When it swells to a certain extent, it may rupture on its own. However, the duct remains blocked, so once the superficial mucosal epithelium heals and forms a scab, the cyst fluid accumulates again, causing it to swell once more.
Thus, the recurrence of mucoceles is closely related to children's habit of biting their lower lips. The key to prevention lies in correcting children's lip-biting habits promptly.
Under normal circumstances, teeth are positioned between the lips and tongue, and the pressure from the tongue muscles and labial-cheek muscles is balanced both inside and outside the teeth. This balance is crucial for maintaining the proper alignment of teeth and the natural shape of the lips, especially during childhood growth and development. If a child has the habit of biting their lips, this balance is disrupted, inevitably affecting the alignment of teeth and the natural state of the lips, leading to a series of deformities.
The above advice addresses the question, "What causes the habit of biting the lower lip?" and I hope it is helpful to you. Wishing you good health!
