After just a few days, the gums (gingiva) react to dental plaque with an inflammation called gingivitis.
The inflammation at the gum line (gingivitis) turns the gums red to dark red, because the blood vessels in the connective tissue there are dilated due to the inflammation.
If optimal oral hygiene at home is practiced, the bacterial plaque is removed regularly and the gums can recover within a few days.
Gingivitis is not a rare inflammation. Every person has several of these areas in their mouth throughout a lifetime. However, they are a sign that these areas were not cleaned properly. Such areas also pose a risk for developing periodontitis.
During pregnancy, there is an increased tendency for gingivitis due to hormonal changes. Pregnant women should pay particular attention to good oral hygiene and see a dentist during their pregnancy.
