Gingivitis is very common. Public health and dental sources say it is an early form of gum disease, and one source notes about 1 in 5 Australians has it while another reports gingival bleeding affects 55% of adults in the UK; U.S. sources also describe gum disease as affecting a large share of adults and being especially common with age.

What that means

  • Gingivitis can happen to almost anyone, because it usually starts when plaque builds up along the gums.
  • It often causes red, swollen, or bleeding gums, but it can be mild enough that people do not notice it right away.
  • It is usually reversible if treated early with better brushing, flossing, and dental care.

Why it matters

If gingivitis is left alone, it can progress to periodontitis, which is a more serious and harder-to-reverse form of gum disease. That is why even though it is common, it is worth taking seriously.

Quick take

  • Common: yes, very.
  • Dangerous by itself: usually not if caught early.
  • Worth treating early: definitely, because it can get worse over time.

TL;DR: Gingivitis is one of the most common dental problems, but it is also one of the easiest to improve early with good oral hygiene and a dental checkup.
