The upward curling of the upper lip requires correction based on the underlying cause. Common reasons include bad habits, maxillary protrusion, dental protrusion, and hypertrophy of the soft tissue of the upper lip. It is necessary to alleviate the symptoms through behavioral correction, orthodontic treatment, surgical treatment, and other methods based on the specific cause. It is important to seek medical attention promptly for diagnosis. Here are some common causes and corresponding treatment methods:

1. Bad Habits

If one does not develop good habits in daily life and frequently curls up the upper lip, it may lead to changes in the shape of the upper lip. It is necessary to correct one's behavior to avoid the continuous worsening of the condition.

2. Maxillary Protrusion

If there is maxillary protrusion, orthodontic treatment should be promptly received to push the maxilla backward and avoid further protrusion. However, the treatment process can be lengthy, and regular diagnosis and further treatment are required during this period.

3. Dental Protrusion

If there is poor dental development or dental malformation, orthodontic braces should be worn promptly under medical supervision to fix the position of the teeth.

4. Hypertrophy of the Soft Tissue of the Upper Lip

If the local soft tissue is hypertrophic, it may lead to symptoms such as swelling and enlargement, which may also affect appearance. Surgical treatment should be promptly received to remove the hypertrophic part. In addition, this condition may also be related to genetics, which generally does not require special treatment and has no impact on physical health.

It is important to maintain local cleanliness and care. If the condition affects appearance, it is necessary to avoid feelings of inferiority and anxiety.
