What is the bump/gland called behind a dogs front teeth?

Just behind the two middle incisors, there’s a bump in cat and dog mouths called the incisive (from the word incisor) papilla (bump). Near the center of it, there’s a hole leading to a duct. That duct leads to Jacobson’s organ, otherwise known as the vomeronasal organ (pronounced: vo- mare- oh). That organ lives in the septum of the nose and connects directly to the amygdala, The amygdala is the seat of emotions in the brain. This means the incisive papilla gives your pet direct access to the emotions through a chemical analysis of the molecules that make their way up the incisive duct. Molecules like pheromones are thought to be analyzed this way.

You are most likely looking at a salivary gland behind the teeth, and most likely looking at the parotid gland that comes down through the soft palata and behind the upper teeth. If you are looking at the lower teeth/tongue, the gland just under the tongue is likely the sublingual gland.

If you are seeing anything abnormal with the glands, such as swelling, redness, pain or discomfort, then having your vet take a look at it is best. Your vet can help determine if there is anything out of the ordinary that may need care.
