Large incisors are not necessarily an adenoid face. Adenoid face is mainly characterized by long maxilla, protruding maxillary bone, anterior extension of incisors, thick lips and expressionless face. Adenoid facies is mainly due to adenoid hypertrophy, hyperplasia, recurrent inflammation , mouth breathing symptoms, dyspnea, snoring, resulting in the occurrence of adenoid facies. Currently, it is believed that adenoid hypertrophy has little possibility of self-healing, and surgical removal is usually performed as early as possible (at the age of 5-6 years) to prevent the occurrence of adenoid facies. If adenoid facies is already present, orthodontic treatment is recommended to improve the appearance by aligning and expanding the arches. Large incisors may be the result of new permanent teeth, not necessarily adenoid facies, so it is important to consult a doctor for timely examination and advice.
