Pets need anesthesia for dental cleanings because they do not sit perfectly still, and procedures like scaling and probing while they are awake can lead to injuries to their teeth and gums. Anesthesia ensures that the pet is completely still, allowing for a thorough and safe dental cleaning. Additionally, obtaining dental radiographs or a CT scan requires the pet to be asleep and motionless to get accurate and clear images. Scaling, particularly under the gumline, can be uncomfortable for pets, making anesthesia necessary to prevent distress and ensure the procedure is completed effectively. Furthermore, a full oral exam cannot be performed on an awake animal, increasing the likelihood of missing potential problems that could affect the pet’s overall health.
