The short answer
Gingivitis is inflammation of the gum tissue from plaque, while periodontitis is gum and supporting-bone destruction that can follow untreated inflammation.

What is the direct answer?
What does this question mean?
Gingivitis begins when plaque bacteria irritate the gingival margin. Periodontitis develops when inflammation extends into the periodontal tissues and causes attachment and bone loss.
What can you do next?
Brush twice daily with a soft brush, clean between teeth, and arrange an examination if bleeding or swelling persists. A dentist may measure pocket depths, assess attachment, and take radiographs when bone loss is suspected.
When should you seek dental care?
Seek care for persistent bleeding, bad breath, gum recession, loose teeth, pus, or pain when chewing. Facial swelling, fever, or difficulty swallowing needs urgent dental assessment.
What should you ask the dentist?
Ask whether the findings are gingivitis or periodontitis, whether pocket measurements or radiographs are needed, and which areas need professional plaque or calculus removal.
