If you need to remove stitches after tooth extraction, you usually only need to pay for the medication change, which costs about$15 to$25. Normal extractions do not require stitches if the trauma is small, but there are special cases, such as misplaced eruption of blocked teeth, which are also called wisdom teeth. If the wisdom tooth is partially erupted or has an ambiguous obstruction, the gum mucosa usually needs to be cut and sutured after the wisdom tooth is extracted; or if the gum is torn after the other normal teeth are extracted, the gum also needs to be sutured to avoid more bleeding after the gum is torn. The stitches are usually removed in 7 to 10 days after tooth extraction. While waiting for the stitches to be removed, you need to pay attention to your diet and try to eat a light, warm and cool liquid and semi-liquid diet.
