While a weak chin is often caused by genetics, physical trauma can also be a contributing factor. Some people may develop a weak chin as they age due to a reduction in collagen and elastin in their facial tissue, which causes the chin to lose volume and appear to recede. This can be corrected without surgery.
If you have a family history of a weak chin or have experienced physical trauma or excessive thumb-sucking during childhood, you may be more likely to develop a weak chin. While a weak chin is usually harmless, severe cases can cause pain and problems with speaking, eating, and sleeping. If you’re experiencing any of these symptoms, contact your doctor for advice on whether surgical treatment may be necessary.
