Hello, I suggest calling your dentist to report these symptoms. Your dentist will review the medical history and most likely Schedule a follow up visit to check the extraction site and further diagnosis any problems. Continue to rinse the area well with warm salt water. Are there any symptoms such as soreness, swelling, drainage or pain at the extraction site? A delayed healing may require antibiotic medication. Take some antiinflammitory medication such as Tylenol or Advil to assist healing. Make sure a proper diet with balanced vitamins has been resumed. Blood loss, if excessive, can result in dehydration and low iron. Kerp well hydrated. Infection can have some systemic effects that can cause weakness as your body heals Next steps include further diagnosis with your physician and blood tests to diagnosis other medical conditions that could cause these symptoms. I hope these suggestions are helpful. Thank you for your inquiry.
