Many complicated anatomical structures are involved in the tasks we take for granted as part of our daily lives. Did you know your mandibular foramen is essential for talking, chewing, and even creating the look of joy on your face when you bite into a delicious treat? We're here to cover exactly where it is, what it does, and when it's important.
The opening of your mouth consists of two parts: your upper jaw (maxilla) and lower jaw (mandible). These vital bones work in sync to help you eat, speak, and create facial expressions. The lower jaw is the only bone in your skull that moves. It moves up and down during these actions to chew, help create sounds, and change the shape of your mouth. Your lower jaw connects to your skull via your temporomandibular joint (TMJ).
Your mandibular foramen itself is the canal opening on each side of your lower jaw (which explains the “mandibular” part of the name). While it doesn’t contain any muscle itself, it is connected to your face and neck muscles.
This essential structure houses nerves and blood vessels as they traverse from your mouth to elsewhere in your body. These nerves and vessels ensure you can feel sensation from your teeth and supply your bones, skin, muscles, teeth, gums, and other tissues with blood.

Some individuals have even been found to have an extra canal or multiple inferior alveolar nerves. The location of your foramen may be asymmetrical on opposing sides of your jaw.
Helpful tip: Your dental or medical professional may use X-rays or other imaging technology to help determine the various characteristics of your mandibular foramen.
Your dental or medical professional's understanding of your mandibular foramen is essential in any related procedure. This is because it protects vital nerves and arteries, so damaging them could cause nerve pain and other complications. Additionally, the location of your mandibular foramen helps trace the path of your mandibular canal and the tissues it protects.
Fortunately, dental and medical professionals are specially trained to navigate this challenge to limit any procedure or treatment risk. If you have questions or concerns about your mandibular foramen, they'll be happy to address them and put you at ease.
Your mandibular foramen may be important for:
You've done a great job reading up on this unique feature of your lower jaw. You now have a great understanding of what your mandibular foramen does to protect your nerves and arteries and why that's crucial for speaking, eating, and even making facial expressions, all of which are important for that delicious treat we mentioned earlier.
