Is it possible to have both gingivitis and bone loss?

Sequential: Gingivitis is a reversible form of gum disease and typically does not have bone loss associated with it. The swelling makes the gums very puffy and red. If allowed to go on long enough, it will progress to damaging the bone that surrounds and supports the teeth and can eventually lead to tooth loss. So as you can see, one can lead to the other. Best to stop the infection in the early stages.

Yes. : Having gingivitis alone doesn't mean that you have bone loss, but if you have bone loss, then you likely have gingivitis as well. Gingivitis left untreated can lead to periodontitis which is categorized by bone and attachment loss.

No: Not in the same place at the same time. If the disease has affected the supporting bone of the teeth, you now have the more advanced stage of the disease, periodontitis.

Yes: If not properly treated gingival inflammation (gingivitis) can progress to periodontitis (bone loss).

Indirectly, Yes: Nearly everyone has gingivitis. If you have any plaque on your teeth anywhere, you'll have some associated gingivitis. However, this is reversible with a professional "cleaning" & excellent oral hygiene. If it's left untreated, however, it very often progresses to "periodontitis, " which leads to irreversible bone loss. So, gingivitis by itself does not destroy bone, but it can get worse over time.

Yes: If the gingivitis becomes severe it can lead to bone loss around the teeth. However, gingivitis is easily treated by your dentist.
