Why Checkups Matter: Gum Disease Is Common

Nearly half of U.S. adults over 30 have periodontitis. Learn the warning signs and how routine checkups protect your teeth.

How common is gum disease in adults?

Gum disease is far more common than most people realize. A CDC-led national study published in the Journal of Dental Research in 2012 found that 47.2% of U.S. adults age 30 and older had periodontitis, and the rate climbed to 70.1% among adults 65 and older. Because early gum disease is usually painless, many people do not know they have it.

Periodontitis is a chronic infection of the gums and the bone that holds the teeth. It starts when plaque bacteria build up along the gumline and harden into tartar that brushing cannot remove. The National Institute of Dental and Craniofacial Research identifies gum disease as a major cause of tooth loss in adults, which is why catching it early matters so much.

How does gum disease progress?

Gum disease usually begins as gingivitis, a reversible inflammation of the gums, and can progress to periodontitis, where the gums separate from the teeth and the supporting bone starts to break down. Without treatment, advanced periodontitis loosens teeth and can lead to their loss. Each stage is easier and less expensive to treat than the one after it.

General stages of gum disease. Only a dental exam can confirm which stage applies to you.
StageWhat happensOutlook
GingivitisRed, swollen gums that bleed easilyReversible with cleanings and better home care
PeriodontitisGums pull away from teeth, forming pockets; bone loss beginsControlled with deep cleaning and maintenance visits
Advanced periodontitisLoose or shifting teeth, painful chewingCan lead to tooth loss without treatment

What are the warning signs of gum disease?

According to the National Institute of Dental and Craniofacial Research, warning signs include bad breath that will not go away, red or swollen gums, tender or bleeding gums, painful chewing, loose teeth, sensitive teeth, and gums that have pulled away from the teeth. Smoking and diabetes raise the risk. Any of these signs is a reason to book an exam.

  • Gums that bleed when you brush or floss
  • Persistent bad breath or a bad taste
  • Gums that look red, puffy or are pulling back
  • Teeth that feel loose or bite differently

How do regular checkups prevent tooth loss?

Professional cleanings remove the hardened tartar that home care cannot, and exams measure the gum pockets around each tooth to spot periodontitis before it causes pain or bone loss. Most patients do well with a cleaning and exam every six months, while patients with a history of gum disease may need more frequent maintenance visits, set by the McLaren Dental Associates team after measuring your gums.
