Kidney Trouble Could Mean Tooth Loss for Older Women | Health


  • Kidney disease may cause tooth loss in older women

  • Older women were 40 percent more likely to have fewer than 20 teeth, the minimum number needed for adequate chewing and speech

  • Kidney health is linked to oral health

WEDNESDAY, June 12, 2024 (HealthDay News) — Older women with chronic kidney disease may lose so many teeth that they can't chew and speak effectively, a new study warns.

Postmenopausal women with kidney disease have fewer than 20 teeth, the minimum number needed for adequate chewing and speech, researchers report June 12 in the journal. Menopause.

Researchers note that this type of tooth loss is also associated with an increased risk of stroke and other systemic diseases, such as diabetes, thyroid disease and osteoporosis.

The research team, led by Dr. Ki-Ho Chung, associate professor at Chonnam National University School of Medicine, concluded: “Our findings suggest that preventing and managing mineral and bone metabolism disorders in postmenopausal women with chronic kidney disease may be useful in preventing tooth loss to It's important.

In a background note, the researchers explain that kidneys play a vital role in health by filtering waste and toxins from the blood.

Kidney function tends to decline after menopause and is associated with decreased estrogen levels in women going through menopause.

For the study, researchers analyzed the health records of nearly 65,000 Korean women aged 40 to 79.

They found that the kidneys' ability to effectively filter blood was related to the number of teeth in a woman's mouth.

The results showed that adults have 32 permanent teeth, but women with poor kidney function were at higher risk of having fewer than 20 permanent teeth. This is especially true for women ages 66 to 79.

Researchers note that chronic kidney disease can significantly affect bone health and mineral metabolism, both of which can lead to tooth loss.

Inflammation and reduced salivation caused by kidney disease can also lead to tooth loss, they added. Salivation is important for dental health, and inflammation plays a role in gum disease and bone health.

“This study highlights the known link between chronic kidney disease and bone metabolism,” said Dr. Stephanie Faubian, medical director of the Menopause Society.

“For postmenopausal women with chronic kidney disease, in addition to careful efforts to protect kidney function, more attention needs to be paid to oral and bone health. Rather, oral health is a window into overall health, and good oral hygiene is important for all ages. Women all matter,” Faubion added in a society press release.
