The left infraorbital nerve block anesthetizes which teeth?

Left maxillary molars
Left mandibular premolars and molars
Left maxillary premolar, canine, and incisors
Left mandibular canine and incisors

The correct answer is: Left maxillary premolar, canine, and incisors

The left infraorbital nerve block is a local anesthetic technique used to numb the teeth and tissues on the left side of the upper jaw. The infraorbital nerve provides sensory innervation to the maxillary premolar, canine, and incisor teeth. Option A is incorrect because the maxillary molars are innervated by the posterior superior alveolar nerve and do not receive anesthesia from the left infraorbital nerve block. Option B is incorrect because the mandibular teeth, including premolars and molars, are innervated by the inferior alveolar nerve and do not receive anesthesia from the left infraorbital nerve block. Option D is incorrect because the mandibular canine and incisor teeth are innervated by the mental nerve and do not receive anesthesia from the left infraorbital nerve block.
