This is classified as a Class III malocclusion. This condition not only affects facial appearance but can also lead to difficulties with chewing, speaking, and other oral health issues if not treated promptly.<\/span><\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400; font-family: arial, helvetica, sans-serif; font-size: 14pt;\">In young children, an underbite may appear during the mixed dentition stage when baby teeth begin to be replaced.

Therefore, if orthodontic treatment is performed at the right time\u2014especially between ages 6\u201311 before puberty\u2014the ability to improve skeletal underbite can be highly effective.<\/span><\/p>\n<h2 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"3_Causes_of_Underbite\"><\/span><span style=\"font-family: arial, helvetica, sans-serif; font-size: 14pt;\"><b>3.

Environmental Factors<\/i><\/span><\/strong><\/h3>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400; font-family: arial, helvetica, sans-serif; font-size: 14pt;\">Certain environmental factors during childhood may worsen an underbite. For example, mouth breathing, airway obstruction caused by enlarged adenoids, or respiratory conditions may make it difficult for children to breathe through the nose, forcing them to breathe through the mouth regularly. This can negatively affect upper jaw development and cause it to grow insufficiently.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400; font-family: arial, helvetica, sans-serif; font-size: 14pt;\">Additionally, incorrect tongue posture or tongue thrusting habits may also cause the lower jaw to develop more strongly than the upper jaw, increasing the risk of underbite.<\/span><\/p>\n<h3 style=\"text-align: justify;\"><strong><span style=\"font-family: arial, helvetica, sans-serif; font-size: 14pt;\"><i>3.2. Genetic Factors<\/i><\/span><\/strong><\/h3>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400; font-family: arial, helvetica, sans-serif; font-size: 14pt;\">Tooth structure, jawbone growth, and tooth eruption patterns are strongly influenced by genetics. Therefore, children may inherit dental irregularities such as crowded teeth, misaligned teeth, a short upper jaw, an overdeveloped lower jaw, or skeletal underbite conditions from family members.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400; font-family: arial, helvetica, sans-serif; font-size: 14pt;\">In addition, certain genetic syndromes may also be associated with underbite, such as Rabson-Mendenhall syndrome, severe Binder syndrome, Treacher Collins syndrome, acromegaly, and other developmental disorders.<\/span><\/p>\n<h3 style=\"text-align: justify;\"><strong><span style=\"font-family: arial, helvetica, sans-serif; font-size: 14pt;\"><i>3.3.

Children may experience difficulty eating, chewing, and swallowing, and may become less interested in food. Long-term chewing with an incorrect bite can also increase pressure on the jaw arch, worsening the condition, causing jaw pain, and affecting digestion.<\/span><\/p>\n<h3 style=\"text-align: justify;\"><strong><span style=\"font-family: arial, helvetica, sans-serif; font-size: 14pt;\"><i>4.2.

In addition, the protruding lower jaw and crooked or uneven teeth may alter the shape of the mouth, making the face appear longer and reducing self-confidence during communication.<\/span><\/p>\n<h3 style=\"text-align: justify;\"><strong><span style=\"font-family: arial, helvetica, sans-serif; font-size: 14pt;\"><i>4.3.

When the upper and lower jaws are imbalanced, children may have difficulty speaking, produce unclear sounds, or experience distorted pronunciation. Some cases may also involve lisps, stuttering, or less fluent communication.<\/span><\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: arial, helvetica, sans-serif; font-size: 14pt;\"><span style=\"font-weight: 400;\">Due to these unwanted effects, underbite should be treated as early as possible. In particular, the period from <\/span><b>6\u201312 years old<\/b><span style=\"font-weight: 400;\"> is considered the \u201cgolden age\u201d for effectively treating underbite and jawbone discrepancies in children.<\/span><\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400; font-family: arial, helvetica, sans-serif; font-size: 14pt;\">During this stage, parents should bring their children to a reputable dental clinic specializing in pediatric orthodontics. After examining the teeth and jaw structure, the orthodontist will assess the severity of the condition and create an appropriate treatment plan.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: arial, helvetica, sans-serif; font-size: 14pt;\"><span style=\"font-weight: 400;\">Depending on age and severity, children aged <\/span><b>6\u201312 years old<\/b><span style=\"font-weight: 400;\"> may be instructed to use orthopedic appliances such as <\/span><b>Facemask<\/b><span style=\"font-weight: 400;\"> appliances, while children aged <\/span><b>13 years and older<\/b><span style=\"font-weight: 400;\"> may consider more advanced orthodontic methods such as the <\/span><b>MEAW archwire<\/b><span style=\"font-weight: 400;\"> technique to effectively improve underbite.<\/span><\/span><\/p>\n<h3 style=\"text-align: justify;\"><strong><span style=\"font-family: arial, helvetica, sans-serif; font-size: 14pt;\"><i>4.4.

When the bite is misaligned, oral hygiene often becomes less effective because the toothbrush cannot properly clean crowded, crooked, or hard-to-reach areas between teeth and around tooth roots. This creates favorable conditions for bacteria to accumulate and grow, increasing the risk of gingivitis, tooth decay, periodontitis, bad breath, and other oral health problems.<\/span><\/span><\/p>\n<h3 style=\"text-align: justify;\"><strong><span style=\"font-family: arial, helvetica, sans-serif; font-size: 14pt;\"><i>4.5.

These problems may interfere with daily activities, make eating uncomfortable, and significantly affect overall health.<\/span><\/span><\/p>\n<h2 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"5_Treatment_Options_for_Underbite\"><\/span><span style=\"font-family: arial, helvetica, sans-serif; font-size: 14pt;\"><b>5.

Underbite has a strong hereditary component. If family members have this condition, children are also at higher risk of developing it. Many cases are related to inherited jawbone structure and tooth positioning. In addition, environmental factors such as thumb sucking, tongue thrusting, prolonged pacifier use, or abnormalities during jaw development may also contribute to underbite.<\/span><\/p>\n<h3 style=\"text-align: justify;\"><strong><span style=\"font-family: arial, helvetica, sans-serif; font-size: 14pt;\"><i>6.2.
