When it comes to malocclusion, the first thing that comes to our mind is “misalignment”, “unattractive” and other problems related to appearance. But does malocclusion simply affect our appearance? The orthodontist’s heart has been crying out “please, let’s focus on the inside too!” The harm of malocclusion is far more than most patients can imagine. 1, affect the development of the dental and jaw surface In the process of growth and development of children, malocclusion will affect the normal development of the soft tissues of the dental and jaw surface. If the anterior teeth are not treated in time, the lower arch will restrict the development of the front jaw, and the lower jaw will develop excessively forward due to the lack of coordination between the upper and lower arches, forming a sunken middle 1/3 of the face and an anterior jaw deformity. Interpretation: It means that malocclusion as a child will affect the face as an adult through the development of bone. If the child is a “small envelope” when he/she is small, the relationship between the teeth will continue to affect the development of the jaw bone, and will become a “big envelope” when he/she grows up. 2, affect the oral health Misaligned teeth are crowded and misaligned, because it is not easy to self-clean, so it is good to develop caries, periodontal inflammation, and often cause periodontal damage due to the misalignment of teeth. Interpretation: In fact, even if the teeth are arranged neatly, not everyone can brush in place, not to mention the teeth in hiding ~ crowded and misaligned teeth are not only unattractive, but also make brushing difficult instantly up several notches! 3, affect the oral function Severe malocclusion can affect the normal function of the oral cavity, such as anterior teeth will affect the chewing function and pronunciation; back teeth lock teeth together can affect the chewing function; severe mandibular protrusion will cause abnormal swallowing; severe jaw recession will affect normal breathing. Interpretation: severe malocclusion will directly affect the two very important and fun oral functions in daily life, such as speaking and eating, which is especially important for chatterers and eaters; more serious cases will also affect the respiratory function. 4, affect the temporomandibular joint When malocclusion interferes with the teeth and early contact, the limits and trajectory of the jaw opening and closing, anterior extension and lateral movement will be abnormal, which will further affect the function of the temporomandibular joint and even lead to organic lesions. Interpretation: Errors in the relationship between the teeth will cause the condyles in the TMJ to be overwhelmed and unable to find their correct position, thus causing diseases of the joint. 5, affect the appearance of appearance All types of malocclusion can make you look wrong somewhere-open lips and teeth, double jaw protrusion, long face or short face shape. Facial malocclusion can also have a psychological impact on patients, especially young patients. Interpretation: How else can you play happily together if you look too special?
