Pregnancy gingivitis is caused by
Pregnancy gingivitis results from plaque inflammation amplified by hormonal changes in the gums.
The short answer
Pregnancy gingivitis is caused by plaque-induced gum inflammation that can become more pronounced as pregnancy hormones change the gums’ response to plaque.
Which part of the gums does pregnancy gingivitis affect?
The condition affects gingiva along the gum margins. Hormonal changes do not create plaque, but they can make swollen tissue bleed more readily when plaque remains.
How does plaque trigger inflammation during pregnancy?
Plaque bacteria release irritants that activate gingival inflammation. Nausea, vomiting, fatigue, altered eating, or difficult brushing can make plaque control harder.
When should a dentist check possible pregnancy gingivitis?
A dentist examines margins, tartar, and cavities and measures bleeding areas. Care may include cleaning, brushing instruction, interdental cleaning, and treatment of decay or infection.
Which daily cleaning routine can help prevent pregnancy gingivitis?
Use a soft brush with fluoride toothpaste and clean between teeth daily. After vomiting, rinse with water and wait before brushing, and tell the dental team about pregnancy and medicines.
