Background: Although international guidelines emphasized that pregnant patients should receive proper dental treatment, many dentists are still hesitant to do so. This study aimed to determine the knowledge, attitude, and practices of dentists towards offering dental treatment to pregnant women in Jordan.Methods: An online survey was distributed to 1000 dentists using social-media applications between August and October, 2019. The survey consisted of three sections; dentists’ knowledge about the association between oral diseases and pregnancy, their participation in training courses, and their practices regarding various dental treatments during pregnancy. Descriptive statistics were obtained and Chi-square tests were used to measure the association between demographic variables and knowledge, attitude, and practices variables. Significance was considered at P-value < 0.05.Results: A total of 547 (54.7%) responded to the questionnaire. Only (37.5%) agreed that periodontal diseases might increase risk of adverse pregnancy outcomes. Almost (75.9%) did not attend any training program. The 2nd trimester was the most preferable time to do all dental procedures. There was a tendency to perform scaling and fillings especially in the 2nd trimester (82.4%), (86.1%) respectively. The majority of dentists would feel comfortable to do RCT (72.0%) or extraction (60.0%) in the 2nd trimester, whereas greater caution was apparent on 1st and 3rd trimester. A proportion of (32.5%) thought that taking x-rays during pregnancy was contraindicated. About (53.7%) didn’t know about the safety to administer nitrous oxide sedation during pregnancy. Around (75.9%) refused to prescribe non-steroidal anti-inflammatory drugs to pregnant women. By far, paracetamol was the drug of choice (96.9%) to prescribe as an analgesic and amoxicillin as an antibiotic (89.2%).Conclusion: lack of knowledge, poor attitude and incorrect practices were observed among surveyed dentists with regards to management of pregnant women. Thus, further education courses about international guidelines are needed to correct the common misconceptions and negative attitudes and practices of dentists in treating pregnant women.
