After wisdom teeth extraction, the upper row of teeth feel a little convex forward generally has nothing to do with the extraction of wisdom teeth, it may be caused by bad oral habits such as finger-sucking habits, periodontitis and so on. 1. Bad oral habits such as finger-sucking habits: the pressure of finger-sucking can cause the upper front teeth to protrude forward, which may cause the upper row of teeth to protrude forward a little. 2. Periodontitis: Periodontitis is a common oral disease that can cause alveolar bone resorption, tooth loosening, and in severe cases, the upper front teeth will be shifted in a fan-shaped manner, which may cause the upper row of teeth to protrude forward a bit. Proximal and middle blocked wisdom teeth may have the power to erupt forward, but there is generally no relationship between wisdom teeth extraction and the upper row of teeth projecting forward a little. It is recommended to go to the hospital in time, to clarify the cause of the disease, and to give targeted treatment or treatment under the guidance of the doctor.
