I have a strong instinct to faint from low blood-pressure because of blood and injury. How do I get a molar surgically extracted (large root filling, tooth cracked and decayed) and deal with the bleeding wound afterwards? Can the amount of bleeding be reduced. Can any dressings, gels etc. be applied? Would sedation help me or would it lower my blood pressure and so add to my problems ? Have you treated any other patients with this blood/injury fainting problem ?
