A protruding mouth, also known as a protruding mouth, can often be improved with braces. Braces are professionally known as orthodontic braces, and their main function is to correct malocclusion. Wearing braces is in fact orthodontic treatment, and protruding mouth is a common manifestation of malocclusion, and wearing braces can usually help to improve the protruding mouth problem. However, some patients with protruding mouths may not be able to achieve good results with braces alone, and may need to have their teeth extracted first to free up some space, and then wear braces to encourage the recovery of the front teeth, thus improving the protruding mouth. Generally speaking, a protruding mouth is a case of teeth protruding forward, which can be treated with orthodontics alone, such as braces, to achieve good results. However, if the dental bed and teeth protrude together, the protruding mouth belongs to the bony protrusion, the effect of braces is poorer, and this situation needs to be treated by orthognathic orthodontics. If the patient finds the protruding mouth, he/she should consult the doctor in time and choose the way of improvement under the doctor’s guidance.
