Periodontal disease, pregnancy hormones and osteoporosis can also cause loose teeth, according to Colgate. Loose teeth signify an underlying dental problem, requiring the services of a dentist.
Gum disease not only affects the gums, but causes loosening of teeth as well, according to WebMD. Gum disease is a result of germs that reside on the gums and teeth and feed on sugar present in food, leading to the formation of plaque. The plaque hardens over time, forming tartar or calculus. This material irritates the gums, causing them to separate from the teeth.
Increased levels of progesterone and estrogen during pregnancy can also lead to loosening of teeth, reports the American Family Physician. This type of loosening happens without the presence of gum disease. Loosening of the teeth occurs due to the effect of hormones on the bone and ligaments that support the teeth.
Osteoporosis is a bone disorder that reduces bone density, therefore weakening bones in the body, explains Delta Dental. Weak bones cannot hold teeth in place, leading to loosening of the teeth. This disease doesn’t discriminate between age and gender, though it's more common in women who are 50 years and older. Osteoporosis does not stop at loosening of the teeth; it can lead to tooth loss.
