Dogs generally require anesthesia or very heavy sedation before dental cleanings, dental x-rays, or complete dental examinations.
Sometimes, local anesthesia and general anesthesia are used together for the same procedure.
For example, some veterinarians use general anesthesia to place the patient into a state of unconsciousness, then inject a local anesthetic agent into the skin and underlying tissues where surgery will be performed.
General anesthesia is used for more invasive types of surgeries or for procedures likely to be very painful.
Examples include repairing a broken bone or performing surgery involving the abdominal or chest cavities.
