Can You Get a Tooth Filling While Pregnant?

August 12, 2025

Pregnancy is a time of significant change ,  physically, emotionally, and hormonally. But what if you develop a cavity while expecting? You might wonder: can you get a tooth filling while pregnant, or is it better to wait? Good news ,  you don’t have to delay necessary dental care. In fact, maintaining oral health during pregnancy is not just safe, but essential for your well-being and your baby’s.

Let’s dive into the facts and expert advice on dental fillings during pregnancy, safety concerns, ideal timing, and how to manage dental issues safely when you're expecting.

Why Going to the Dentist While Pregnant Is So Important

Hormonal changes during pregnancy can increase your risk of gum disease, tooth decay, and other dental problems. Conditions like morning sickness and cravings for sugary foods can worsen oral health, leading to cavities. If left untreated, these issues may affect both maternal health and fetal development.

That’s why most dentists ,  and even the American College of Obstetricians ,  recommend regular dental care during pregnancy. And yes, this includes getting fillings if you have cavities.

Tooth Filling During Pregnancy First Trimester: Safe or Not?

Many women worry about dental work while pregnant first trimester. The first three months are crucial for fetal development, and elective procedures are usually postponed during this time. However, can you get a tooth filling while pregnant in the first trimester?

If you have an urgent dental issue, your dentist might go ahead with the treatment. But generally, non-emergency procedures like fillings are better scheduled during the second trimester. It's a balance between maternal comfort and fetal safety.

Second Trimester: The Best Time for Dental Fillings

According to most experts, the second trimester (weeks 13–26) is the safest time for dental procedures. During this period:

  • The baby’s vital organs are formed.

  • There’s less risk from medications or local anesthesia.

  • You’re likely to be more comfortable in the dental chair.

So if you're wondering “can a dentist fix cavities while pregnant?”, the second trimester is when the answer is a confident yes.

Tooth Filling During Pregnancy Third Trimester: Proceed With Caution

The third trimester brings different challenges. Lying on your back for extended periods can be uncomfortable due to the weight of the growing uterus. There’s also a higher risk of preterm labor from stress or discomfort.

Still, if the cavity is causing pain or could lead to infection, your dentist may proceed. It’s all about managing the risks versus benefits.

Tooth filling during pregnancy third trimester should be done with extra care and only when necessary.

Is Dental Anesthesia Safe During Pregnancy?

A major concern is the use of dental anesthesia. So, is dental anesthesia safe during pregnancy?

Yes ,  local anesthesia like lidocaine is considered safe during all stages of pregnancy when administered in controlled amounts. Your dentist will avoid any medication that could cross the placenta or trigger contractions.

Make sure to inform your dentist that you are pregnant so they can tailor the treatment accordingly.

Dangers of Dental Work While Pregnant: What to Know

Are there any dangers of dental work while pregnant? If you're receiving routine procedures like cleanings or fillings using non-toxic dental materials, risks are minimal. However:

  • Dental x-rays are usually postponed unless necessary.

  • Invasive procedures like root canals are approached cautiously.

  • Pregnant women may be more prone to gum sensitivity or tooth decay.

With proper care and a knowledgeable dental team, most risks can be avoided altogether.

How to Treat Cavity During Pregnancy Without Risk

If you're pregnant and suspect a cavity, here are safe steps:

  • Schedule a dental exam ,  don’t delay.

  • Maintain strong oral hygiene: brush twice daily and floss.

  • Rinse with a fluoride mouthwash (consult your OB-GYN).

  • Avoid sugary foods that accelerate tooth decay.

If a cavity is confirmed, can you get a cavity filled while pregnant? Yes ,  especially in the second trimester. Prompt care prevents complications and supports overall health.

Pregnancy and Dental Work: What to Expect

If you're receiving dental treatments while pregnant, here’s what to keep in mind:

  • Tell your dentist about your pregnancy and any medications you're taking.

  • Ask if non-mercury filling materials are available.

  • Keep your OB-GYN informed about any upcoming dental appointments.

Modern dentistry is well-equipped to handle the needs of pregnant women safely and comfortably.
