Poorly processed food forces the stomach and digestive system to work harder, which may eventually lead to digestive disorders.<\/span><\/p>\n<h3 style=\"text-align: justify;\"><span style=\"font-family: arial, helvetica, sans-serif; font-size: 14pt;\"><i><span style=\"font-weight: 400;\">6.3.

As a result, patients may experience jaw pain, chewing muscle fatigue, or pain in the temporomandibular joint area.<\/span><\/p>\n<h3 style=\"text-align: justify;\"><span style=\"font-family: arial, helvetica, sans-serif; font-size: 14pt;\"><i><span style=\"font-weight: 400;\">6.4.

The prominent chin and lower jaw make the face appear unbalanced and sometimes create a less harmonious \u201ccrescent-shaped\u201d facial appearance. When speaking or smiling, the condition becomes more noticeable, which may reduce self-confidence in communication.<\/span><\/p>\n<h2 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"7_Frequently_Asked_Questions_About_Underbite\"><\/span><span style=\"font-family: arial, helvetica, sans-serif; font-size: 14pt;\">7.

Is Tooth Extraction Necessary for Underbite Braces?<\/span><\/i><\/span><\/h3>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400; font-family: arial, helvetica, sans-serif; font-size: 14pt;\">Not all underbite orthodontic cases require tooth extraction. Whether extraction is necessary depends on the severity of the misalignment, the cause of the underbite, the degree of tooth crowding, and the dentist\u2019s treatment plan.<\/span><\/p>\n<h3 style=\"text-align: justify;\"><span style=\"font-family: arial, helvetica, sans-serif; font-size: 14pt;\"><i><span style=\"font-weight: 400;\">7.2.

However, this sensation usually lasts only a short time and gradually decreases as the mouth adapts to the orthodontic appliances.<\/span><\/p>\n<h3 style=\"text-align: justify;\"><span style=\"font-family: arial, helvetica, sans-serif; font-size: 14pt;\"><i><span style=\"font-weight: 400;\">7.3.

Underbite is a condition with a strong hereditary factor. According to many studies, most underbite cases are related to inherited genes from parents or grandparents. If someone in the family has an underbite, future generations are more likely to develop the condition.<\/span><\/p>\n<h3 style=\"text-align: justify;\"><span style=\"font-family: arial, helvetica, sans-serif; font-size: 14pt;\"><i><span style=\"font-weight: 400;\">7.4.

This imbalance causes the lower jaw to protrude noticeably forward. Some cases may be associated with cleft palate deformities, resulting in underdeveloped upper jaw size and upper teeth positioned behind the lower teeth.<\/span><\/p>\n<h2 data-section-id=\"motcks\" data-start=\"0\" data-end=\"44\"><span class=\"ez-toc-section\" id=\"8_Underbite_Treatment_at_Phuong_Thanh_Dental_Clinic\"><\/span><span style=\"font-family: arial, helvetica, sans-serif; font-size: 14pt;\">8.
