Bruxism “Tooth Grinding”

Patients are often concerned about the nocturnal grinding of teeth (bruxism). Often, the first indication is the noise created by the grinding on your teeth during sleep. Or, you may notice wear teeth becoming shorter and more angular (losing their soft curves). One theory as to the cause of grinding is stress. Other theories are the general neurological makeup of the individual causing the tendency to move the jaws during sleep or simply pressure in the inner ear at night.

Night time tooth grinder (Bruxer)The red line indicates where the enamel of the teeth should be.  Grinding of the teeth has worn the enamel off making this person look much older than they actually are.

The majority of cases of bruxism do not require any treatment. If excessive wear of the teeth (attrition) is present, then a mouth guard (night guard) may be indicated.

    Simple diet changes can help your teeth grinding problems. A powerful natural item to be included in your Teeth Grinding Diet for immediate relief is magnesium. A deficiency in magnesium levels is suspected to be one of the causes of many health problems, inducing teeth grinding, migraines, headaches and diabetes. Some magnesium-rich foods you should eat as often as you can are: artichoke, beans, pumpkin seeds, spinach, sweet potatoes to name a few.

    Thank you Jery for adding low magnesium levels as another potential cause of bruxism or tooth grinding. To be a bit more specific, taking powdered magnesium and calcium in a two-to-one ratio daily seems to help some people. These minerals help the jaw muscles relax, particularly at night. Dosage combinations range from 600 milligrams of calcium along with 300 milligrams of magnesium to 1,000 milligrams of calcium with 500 milligrams of magnesium daily. Begin taking a lower dose, if there is little or no relief after 10 to 14 days, increase the dosages. Calcium/magnesium tablets are also available, but they don’t dissolve as readily. When you use the powdered form, dissolve the mineral supplements in an acidic liquid like orange or grapefruit juice. This assists in a more complete uptake.
