Does the orthodontic process hurt? Can small children tolerate it? This is a topic of great concern to many parents and children. Orthodontic braces are bonded to the teeth through special dental materials, usually when first wearing braces foreign body sensation is more obvious, some patients due to the first wearing braces, oral mucosa may also be braces pressure marks, but most patients about 1 week to adapt. The interval between each orthodontic review and force is usually 3-6 weeks, in the beginning of the first week, the teeth feel swollen and painful due to the force, when eating feel weak bite or have a slight pain is normal, but in most cases after a week the symptoms basically disappeared, usually do not recommend taking painkillers and so on. However, if the pain is not relieved after a week, but becomes more severe, and there is significant pain when gently biting or without biting, then you need to contact your primary care physician for a timely consultation. Generally speaking, small children are much more tolerant than adults, but instead, one’s ability to adapt diminishes as one gets older. Therefore, there is no need to worry about children being unable to undergo orthodontic treatment because of pain, unless they visit an informal orthodontic clinic.
