Sucking your thumb does influence the development of your palate and maxilla, though the effects might be subtle and depend on various factors such as the duration and intensity of thumb sucking, as well as individual differences in growth and development.
- Palate Development: The act of thumb sucking can apply pressure to the roof of the mouth (the palate). In young children, whose palates are still developing, this pressure might influence the shape and size of the palate. If thumb sucking is persistent and the thumb is placed in the mouth in a way that exerts upward pressure, it could theoretically encourage a slightly wider palate over time.
- Maxillary Projection: The maxilla is the upper jawbone that forms part of the face and holds the upper teeth. Prolonged thumb sucking might affect the position of the maxilla by influencing the way the upper teeth and surrounding bone structure develop. If thumb sucking leads to changes in the position of the teeth or the way the mouth closes, it might indirectly influence maxillary projection.
- Dental and Orthodontic Considerations: Orthodontists often observe that thumb sucking can lead to misalignment of teeth or changes in the bite. In some cases, this might include an anterior open bite (where the front teeth do not meet when the mouth is closed), which could affect the appearance of the maxilla.
