My 20 year old daughter had her 4 wisdom teeth pulled 2 days ago.  She had has very little swelling and little pain.  Her tongue is almost dark purple/black looking from blood stains and this morning she has a \"blood blister\" or what looks like one in her mouth near one of the extractions.  Anything we can do at home for this?  Is this normal?
Hello, She most likely has a hematoma. This can be from the injection or bruising trauma from biting the tongue. The body will take care of this with time. Healing may involve some tissue changes and even an area of solid feeling tissue can be part of normal healing. You can expect a slow healing process that can take 3 to 6 weeks to totally resort the hematoma. Warm salt water rinses and anti-inflammatory medication such as ibuprofen may assist healing. If the area increases or does not continue to heal, visit the dentist to evaluate if Chat Doctor.  In general, this is not considered an unusual event, and you do not need to worry. It is a very positive sign that there has been little pain and little swelling. This indicates healing is progressing well. Thank you for your inquiry. I hope your daughter will continue to feel better.
