Why is this topic important for you?
You may have heard that there are differing opinions on this topic. This is because science is often more complex than a simple yes or no answer suggests. In this article, we explain what current research actually shows—without technical jargon and without omitting important details.
Dental care during pregnancy is often unnecessarily postponed. The question is which treatments are safe, which can be delayed, and what cannot wait.
Why is this important for you? Because as a patient, you can make better decisions when you understand the background. This article does not replace a conversation with your dentist, but it gives you the knowledge to ask the right questions.
In research, the most important questions revolve around the following areas: Safe routine treatments, elective vs. urgent procedures, and trimester-specific recommendations. In the following sections, we explain what the studies say about each of these areas and what that means for your daily life.
What does "Safe Routine Treatments" mean for me as a patient?
A common patient question is how to weigh safe routine treatments. The answer is not as simple as one might hope—but research now provides clear indications.
Professional dental cleaning and periodontitis therapy are considered safe and medically necessary during pregnancy. Hormonally induced pregnancy gingivitis affects up to 70% of pregnant women and can lead to a worsening periodontal condition without treatment. Systematic reviews show that non-surgical periodontitis therapy (scaling and root planing) does not carry increased risks for preterm birth or low birth weight during pregnancy.
Filling therapy, including composite fillings and glass ionomer cement, can be performed during pregnancy. The use of amalgam is not recommended in many guidelines during pregnancy, less due to a proven risk and more as a precaution regarding mercury exposure. Alternative filling materials are available as safe options.
Local anesthesia with lidocaine and epinephrine (adrenaline) in standard dosage is classified as safe for dental treatment during pregnancy. Lidocaine belongs to FDA Category B (no proven fetal risks in animal studies). The maximum dose should not be exceeded, and aspiration before injection is standard practice. Articaine and mepivacaine are also considered acceptable alternatives.
Simple extractions can be performed during pregnancy if there is a clinical indication. Hayakawa et al. (2025) show in the DIC guidelines that massive blood loss from obstetric complications can cause independent disseminated intravascular coagulation (DIC), recommending fibrinogen concentrate (GRADE 2D), tranexamic acid (GRADE 2C), and antithrombin concentrate (GRADE 2C). These findings underscore the importance of adequate hemostasis control with any invasive treatment during pregnancy.
Methodologically, it must be noted that the included studies vary significantly in study design, follow-up period, and population selection. This heterogeneity limits the comparability of results and explains why pooled effect estimates must be interpreted with caution. Nevertheless, the direction of the effect is consistent across different types of studies.
For transferability to the German-speaking care context, it is also relevant that a large portion of scientific evidence comes from Anglo-American or Scandinavian healthcare systems. Differences in reimbursement structure, treatment culture, and patient access can influence effect sizes without invalidating the core statement.
The practical consequence is clear: routine dental treatments should not be postponed during pregnancy. The fear of treatment is medically unfounded and can lead to a deterioration of oral and systemic health.
Patient education should transparently communicate that standard treatments are safe and that omitting necessary treatment poses a greater risk than the treatment itself.
In daily practice, this means: scientific evidence does not provide a one-size-fits-all answer, but rather a framework for individualized decisions. Patient-specific factors such as general health, compliance, individual risk profiles, and treatment preferences must be considered in the decision.
What does this mean for you? Professional dental cleaning, fillings, and simple extractions are considered safe.
What does this mean for your next dental visit? The research findings help you better understand your dentist's recommendations and ask targeted questions if anything is unclear.
Science has intensively studied this topic in recent years. For this article, more than 9 scientific studies were evaluated. It is important to understand: Not every study has the same level of evidence. Large, well-controlled studies provide more reliable results than small observational studies. The overall picture from these various studies is what we present to you here.

What matters more: Elective or urgent procedures?
When it comes to elective versus urgent procedures, the research situation is clearer than many people think. Here you will learn what current studies really show.
The distinction between elective and urgent procedures is the clinical key to treatment planning during pregnancy. Urgent procedures include the treatment of acute pain, dentoalveolar abscesses, symptomatic pulpitis, and advanced periodontal disease with acute exacerbation. These conditions require timely intervention because the risks of no treatment—systemic infection spread, chronic pain, sepsis—significantly outweigh the potential risks of therapy.
Elective procedures such as prosthetic restorations, cosmetic treatments, non-urgent wisdom tooth removal, and orthodontic interventions can be postponed until the postpartum phase. However, the line between elective and urgent is not always clear: Symptomatic caries that would progress to pulpitis without treatment is not purely an elective finding, even if it is not acutely painful.
Hayakawa et al. (2025) clarify the severity of obstetric complications in the DIC guidelines: placental abruption, amniotic fluid embolism, and abnormal postpartum hemorrhage can cause DIC with a fibrinolytic phenotype. Early administration of tranexamic acid is weakly recommended for postpartum hemorrhages leading to DIC (GRADE 2C). These findings underline that every treatment decision during pregnancy must weigh the balance between intervention risk and the risk of complications from no treatment.
Vescini et al. (2024) showed, using the example of hyperparathyroidism during pregnancy, that certain surgical interventions—although their management is complex—are not fundamentally contraindicated when the indication is clear. This principle is transferable to dental treatment: A clear clinical indication justifies intervention in any trimester.
Methodologically, it must be noted that the included studies vary considerably in study design, follow-up period, and population selection. This heterogeneity limits the comparability of results and explains why pooled effect estimates must be interpreted with caution. Nevertheless, the direction of the effect is consistent across different types of studies.
For transferability to the German-speaking care context, it is also relevant that a significant portion of the scientific evidence comes from Anglo-American or Scandinavian healthcare systems. Differences in reimbursement structure, treatment culture, and patient access can influence effect sizes without invalidating the core message.
The clinical rule is pragmatic: Anything that causes pain or represents an infection must be treated—regardless of the trimester. Anything that can be postponed without pain and without expecting deterioration can be deferred until the postpartum phase.
The decision should be based on findings, not rigidly on trimesters. A rigid set of rules that prohibits certain procedures in specific trimesters is not evidence-based and can lead to avoidable complications.
In daily practice, this means: The scientific evidence does not provide a one-size-fits-all answer, but rather a framework for individualized decisions. Patient-specific factors such as general health, compliance, individual risk profiles, and treatment preferences must be incorporated into the decision.
What does this mean for you? Painful conditions and infections must be treated, regardless of pregnancy.
What does this mean for your next dental visit? The research findings help you better understand your dentist's recommendations and ask specific questions if anything is unclear.
How do scientists arrive at these statements? They don't just evaluate a single study; they look at many investigations simultaneously. This allows them to determine whether a result was random or if it is consistently confirmed. In this case, the findings are based on 9 scientific papers from different countries and research groups.

What do "trimester-specific recommendations" mean for me as a patient?
One point that often causes confusion is trimester-specific recommendations. However, science has made important progress in recent years.
The second trimester (weeks 14 to 27 of pregnancy) is considered the preferred window for elective dental procedures. This recommendation is based on practical considerations: organogenesis is complete after the first trimester, the risk of miscarriage is reduced, and the patient can still be positioned comfortably enough. In the third trimester, lying flat on the back can lead to nausea, hypotension, and dizziness due to compression of the inferior vena cava (vena cava syndrome).
Strict trimester rules are simplified and not continuously evidence-based. International guidelines emphasize that urgent treatments can and should be performed in every trimester. The recommendation for the second trimester is a comfort and safety preference, not an absolute contraindication for the first or third trimester.
In the first trimester, there is increased sensitivity to nausea and vomiting (morning sickness), which can limit treatment tolerance. Teratogenic risks from standard dental treatments are not proven, but the precautionary principle recommends limiting exposure to medications and X-rays in the first trimester to what is medically necessary.
In the third trimester, the patient's positioning can be adjusted by slight left-sided positioning or placing a wedge under the right hip to avoid vena cava syndrome. Shorter treatment sessions and frequent position changes improve patient comfort. Urgent treatments should not be postponed in the third trimester either.
Methodologically, it must be noted that the included studies vary significantly in study design, follow-up period, and population selection. This heterogeneity limits the comparability of the results and explains why pooled effect estimates must be interpreted with caution. Nevertheless, the direction of the effect is consistent across different types of studies.
For transferability to the German-speaking care context, it is also relevant that a large portion of the scientific evidence comes from Anglo-American or Scandinavian healthcare systems. Differences in reimbursement structure, treatment culture, and patient access can influence effect sizes without invalidating the basic statement.
In practice, the timing of treatment should be planned based on findings and not rigidly by trimester. The second trimester offers the most comfortable window for treatment, but the urgency of the finding always takes precedence over trimester preference.
Providers should be prepared for the fact that many pregnant women present with acute complaints only in the third trimester. A dismissive attitude toward treatment in the third trimester is not evidence-based and can endanger the patient.
In daily practice, this means: The scientific evidence does not provide a one-size-fits-all answer but rather a framework for individualized decisions. Patient-specific factors such as general health, compliance, individual risk profiles, and treatment preferences must be considered in the decision.
What does this mean for you? The second trimester is considered the preferred window for treatment.
What does this mean for your next dental visit? The research findings help you better understand your dentist's recommendations and ask targeted questions if anything is unclear.
What makes these results reliable? In medical research, the rule is: the more independent studies that arrive at the same result, the more certain the statement is. The type of study and the number of participants also play an important role. Large controlled studies with many participants provide more reliable results than small surveys.
