My husband had the first stage of a tooth implant done 4 weeks ago. He had a CT scan prior to the procedure which showed excellent bone density etc. His dentist did NOT prescribe antibiotics. He is not a smoker or diabetic. A few days after the procedure he developed a severe infection and was prescribed antibiotics at the ER. The infection cleared but today the entire screw fell out. The size of the the screw is approx. 3-4 mm wide x 10mm long and has a thread. What are his options now?
