<s>[INST] My boyfriend got hit by a baseball about 5 weeks ago and had to get stitches above his lip & inside his mouth.  The doctor took out the stitches above his lip but said the stitches inside his mouth would "dissolve" or fall out.  However, not all of them have fallen out.  Is it normal to take this long or should he call the doctor? [/INST] Thanks for your query, I have gone through your query.The absorbable sutures dissolve or absorbed by the enzymatic process, this might take around 1 to 2 weeks. sometimes it might take months to get disolved. If the sutures are not absorbed even after a month then consult a surgeon and get it checked. Nothing to worry it will not harm you. Maintain hygiene in that area.I hope my answer will help you, take care. </s>
