Patients who breathe through the mouth suffer from crowded teeth and crooked teeth due to the narrowness of the upper jaw and crowding of the teeth. Pressure on the teeth takes them out of their way and orthodontic treatment is required. Mouth breathing should first be addressed by an otolaryngologist.
This treatment is performed by an orthodontist to treat crooked and irregular teeth. Note that if mouth breathing is treated from the start, the likelihood of needing orthodontic treatment will be less felt by reducing orthodontic treatment.
