Torus Palatinus, Torus Mandibularis, Exostosis
Do Bony Knots Have to be Removed?
According to Google, a torus palatinus is a bony knot or protrusion located in the mid line of the palate. A torus is more common on the palate than on the lower jaw or mandible where it is called a torus mandibularis. When the torus is found on the mandible, they are on the inside and usually bilateral, meaning they occur on both sides.
outside of the teeth, they are simply called exostoses (plural for bony knots). They are usually the result of a very strong bite as the body naturally adds bone for its own protection. They are of no concern unless a denture or partial denture is involved. Then they usually require removal.
Tori found in the lower jaw (torus mandibularis) are usually due to excessive stresses on the teeth when chewing, but more especially when swallowing. The body attempts to compensate for this stress by creating more bony support for the teeth. And there is considerable evidence that tori on the upper jaw (palatal) are genetic or inherited.
Although exostoses (bony knots) may be found on other bones in the body, we are mainly interested in those which form on the surfaces of the upper and lower jaws. By definition, exostosis means the formation of additional bone on the surface of existing bone.
If all categories of bony knots are not ulcerated by certain foods, and are not affected by aggressive toothbrusing, they are usually not treated unless the patient has full or partial dentures. These bony knots may be irritated and ulcerated by these appliances and therefore should be removed prior to their placement.
Patients often have exostoses or tori for many years without knowing it. They should not be overly-concerned and it is rare that they are removed unless dentures or partials are involved. They are not malignant and do not cause cancer and should not be a worry to the patient.
