No one knows. Seriously. It just happens. But it's not something bad that needs to be fixed. You can get them on the root of your mouth too (palatal tori). They only time you need to worry about them is if you are having dentures made, because they can keep the dentures from staying in place.
Torus mandibularis (pl. tori mandibular) (or mandibular torus (pl. mandibular tori) in English) is a bony growth in the mandible along the surface nearest to the tongue. Mandibular tori are usually present near the premolars and above the location of the mylohyoid muscle's attachment to the mandible.[1] In 90% of cases, there is a torus on both the left and right sides, making this finding an overwhelmingly bilateral condition.
The prevalence of mandibular tori ranges from 5% - 40%. It is less common than bony growths occurring on the palate, known as torus palatinus. Mandibular tori are more common in Asian and Inuit populations, and slightly more common in males. In the United States, the prevalence is 7% - 10% of the population.
It is believed that mandibular tori are caused by several factors.[1] They are more common in early adult life and are associated with bruxism. The size of the tori may fluctuate throughout life, and in some cases the tori can be large enough to touch each other in the midline of mouth. Consequently, it is believed that mandibular tori are the result of local stresses and not solely on genetic influences.
Mandibular tori are usually a clinical finding with no treatment necessary. It is possible for ulcers to form on the area of the tori due to trauma. The tori may also complicate the fabrication of dentures. If removal of the tori is needed, surgery can be done to reduce the amount of bone, but the tori may reform in cases where nearby teeth still receive local stresses.
clenching or grinding your teeth can cause tori.
mandibular tori-mostly harmless
There is bony lump in the roof of my mouth. They say is is called a tori. What is a Tori and what causes it ?
the mandibular condyles open the jaw
The mandibular frenum is a little tag of tissue that connects the bottom of the tongue to the floor of the mouth. It aids in speech. Some are attached too close to the front of the tongue and it causes speech impediments, but can be fixed by an oral surgeon clipping it.
The mandibular condyle articulates with the mandibular fossae of the temporal bone.
The sub mandibular gland is part of the neck and not the face.
The mandibular arch forms the tooth bearing bones of the upper and lower jaw.
The main causes of a sub mandibular gland tumor are attributed to being exposed to radiation and smoking. Exposure of these substances?æover the course of 10 to 20 years contributes to the form of this tumors.

The tooth that is coming in behind the mandibular tooth is not deciduous, it will be a permanent tooth. These permanent mandibular teeth should be coming in anywhere from 6-10 years of age.
