CHEER Oral Health in Pregnancy Study

Many pregnant people don't get the dental care they need, even though it's safe and important. The CHEER Study offers free dental check-ups, cleanings, and supplies to help participants take care of their teeth and gums during pregnancy. The purpose of this research study is to compare two types of noninvasive oral health interventions to evaluate their effectiveness. We want to learn if one method is more effective in supporting oral health and improving pregnancy outcomes. There are two aims of this study: Aim 1: To evaluate whether a structured oral health intervention reduces periodontal inflammation during pregnancy and postpartum in pregnant people with indicators of periodontal disease. Aim 2: To assess whether a structured oral health intervention is associated with changes in oral health behaviors or birth outcomes in pregnant people with periodontal disease.
