Hi, is torus mandibularis a symptom of an underlying condition? maybe a mineral or nutrient deficiency or adrenal glands problems? thanks

No its not a problem: No this is not A sign of an underlying condition. It may be hereditary or due to a heavy bite And possibly grinding or clenching.

No: Common occurrence. Check your parents and siblings -- likely that one or many have this as well. Nothing to worry about. If becomes a problem, it can be removed. Simply a benign bony growth.

Clenching: Very frequently seen in people who clench or grind their teeth - perfectly normal bone, just an excess amount. Unrelated to diet or any disease state..

Unclear etiology: The etiology of tori is unclear. Most tori are benign, but they can occasionally cause problems and removal is warranted.
