9 Risk Factors for Tooth Loss
Hint: Unhealthy Older Men Who Smoke, Neglect Their Teeth Are at Risk
Nov. 11, 2005 -- Avoiding tooth loss may be partly within your control, new research suggests.
In the Journal of Periodontology, dental experts list nine risk factors for tooth loss due to periodontal disease.
Here's the list:
The ninth finding was that front (anterior) teeth were more likely to be lost to gum disease than teeth at the back of the mouth.
Some of those factors -- such as your age and sex -- won't budge. But others -- like whether you brush your teeth or smoke -- are largely up to you.
Tracking Tooth Loss
The list was created by Khalaf Al-Shammari, DDS, MS, and colleagues. Al-Shammari works in Kuwait's Ministry of Health.
The study was done in Kuwait. It covered all adults who had a tooth removed at 21 randomly chosen general dental practice clinics -- a quarter of such clinics in Kuwait.
The clinics were all run by the Kuwaiti government. Most Kuwaitis who get dental care go to such clinics as part of the country's health system, the researchers note.
The grand totals: 1,775 patients and 3,694 teeth removed. Fourteen patients had all of their teeth taken out.
Leading Reason for Tooth Loss
Gum (periodontal) disease was the leading reason for tooth loss. It's one of the world's main causes of tooth loss, the researchers note.
Men were more likely than women to have a tooth removed. Tooth loss was also more common among patients aged 35 and older.
About three out of 10 patients were smokers or ex-smokers. The link between smoking and tooth loss might have been stronger if more information had been available on the patients' smoking habits and history, the researchers note.
Consequence of Poor Dental Care
Nearly 40% of the patients reported that they had never gotten professional dental maintenance.
Only 13% said they had gotten professional dental care in the six months before their tooth extraction.
Most patients -- 60% -- said they never or only occasionally brushed their teeth. Only about 16% reported brushing their teeth at least twice daily.
