It is a bony growth that develops on the lower jaw, beneath and on the side of the tongue. Tori affects about 27 out of every 1,000 adults, reports the National Institutes of Health, though it's not as well-known as other oral health conditions.
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.
Mandibular tori are usually present on the tongue side of the jaw near the bicuspids ( also known as premolars). They usually – 90% of the time – occur on both sides of the mouth (bilaterally). Mandibular tori are not particularly common – about 5 – 10% of the population will have noticeable mandibular tori.
The most common bony outgrowth was torus mandibularis. Our results show that the genetic factor is dominant in the etiology of oral bony outgrowths.
Torus mandibularis is thought to be caused mainly by environmental factors, such as bruxism, vitamin deficiencies and calcium-rich supplements, although genetic background also plays a key role. Clinical diagnosis is usually straightforward, and investigations are generally not required.
This oral abnormality normally does not cause any serious damage. It will cause discomfort and if the growth continues, mandibular tori can cause pain or disturbed mouths functions.
Because mandibular tori are bone growths, you cannot get rid of them without surgical treatment from your dentist.
This condition is more common in early adult life, and consequently, it is believed that mandibular tori are the result of local stresses and not solely on genetic influences.
In most cases tori are benign and do not require treatment. However, tori will need to be surgically removed to accommodate upper or lower dentures and upper or lower partial dentures (flippers). Tori may also be removed to aid in minimizing food impaction under the excess bone, which will promote improved home care.
The prevalence of mandibular tori in the population can range from 5%-40% and is less common than tori on the palate. Tori has been shown to be more common in Asian, Native American, and Inuit populations.
Believe it or not, clenching and grinding can actually change the shape of your bone. Though not particularly common, some people with bruxism develop bony growths on the inside of their lower jaw, under the tongue. These growths are called mandibular tori, and they are harmless and benign.
Torus mandibularis is a bony sublingual protuberance, typically near the canine and premolar teeth. The etiology of tori is unclear. Possible causes include masticatory hyperfunction, continued bone growth, genetic factors and environmental factors such as diet.
While there is a hereditary component to tori, this does not explain all cases. Tori tend to appear more frequently during middle age of life. Certain ethnic groups are more prone to one torus or the other.
Tori are simply an abnormality; a random bone growth. They do not pose any immediate threat or harm once they have been identified in the mouth, though they do continue to grow over time, and have the potential to cause pain or discomfort if they become too large.
Unfortunately, tori do not shrink over time. They will grow to a certain point, and then stop growing. A surgical team will need to remove them if your dentist deems it necessary.
Dental tori factors include: Trauma or injury to the mouth's interior. Jawbone stress due to teeth grinding and clenching. Lifestyle/diet influences, such as vitamin deficiencies, fish consumption, and calcium-rich diets.
I was given an I.V. for the 1.5-hour procedure on a Thursday. Before I knew it, I was coming out of the anesthesia, and they were helping me up. My mouth was packed with gauze. I wasn't feeling much pain at the time.
The existence of torus mandibularis is not all too common — it's estimated that 12 to 25% of the adult population has these bony overgrowths in the lower jaw. People who have this tori mandibularis usually have two, but they can exist on their own.
A general dentist or oral surgeon can excise the tori and then stitch up the surrounding gum tissue. While tori can be removed under local anesthetic, some offices opt for IV sedation - especially if you have a poor gag reflex. The surgery is like a tooth extraction in terms of recovery.
Due to laser technology, tori dental removal can be virtually pain-free.
TP forms along the midline of the hard palate, whereas TMs form along the lingual aspect of the mandible and is usually bilateral. Tori typically develop during late adolescence and gradually increase in size throughout adulthood.
Dental Bone Spur Removal
An oral surgeon can remove a benign growth using specialized tools. The surgeon removes the soft tissue over the area, finely trims and smooths the bone out, and stitches the tissue back into place.
Osteonecrosis of the jaw (ONJ) is a condition in which one or more parts of the jawbones become dead (necrotic) and exposed in the mouth. These fragments of bone poke through the gums and may easily be mistaken for broken teeth. Both the upper (maxilla) and lower (mandible) jaw can be affected.
Abstract. In this study the presence of mandibular tori was related to conditions associated with parafunctional activity. Parafunction in the form of tooth clenching or grinding has been associated with temporomandibular disorders (TMD) and recently migraine.
Torus mandibularis is a structure that can appear on the inside of the mandible. Therefore, it is possible for tori to influence airway volume by occupying the space for tongue and cause sleep apnoea.
