Pregnancy is a time full of changes — not just emotionally and physically, but also medically. Many expecting mothers begin to evaluate everything more carefully, from what they eat to the medications they take. But what about orthodontic treatment? If you’re wondering, “Is Invisalign safe during pregnancy?” — you’re not alone. Here’s everything you need to know.
Invisalign is a popular orthodontic treatment that uses a series of custom-made, clear aligners to gradually shift your teeth into their desired position. Unlike traditional braces, Invisalign trays are removable, nearly invisible, and typically considered more comfortable.
They’re made of medical-grade, BPA-free plastic and are commonly used by adults who want to improve their smile discreetly — including many pregnant women, according to kieferorthopaedie-zuerich.ch.
Is Invisalign Safe While Pregnant?
✅ The Short Answer: Yes, Generally
Invisalign is generally considered safe during pregnancy. The aligners themselves do not contain harmful chemicals and are BPA-free, meaning they won’t expose you or your baby to toxins.
However, as with any medical decision during pregnancy, it’s important to consult both your dentist/orthodontist and your OB-GYN before starting or continuing treatment.
Key Considerations Before Getting Invisalign While Pregnant
While Invisalign doesn’t involve any medications or invasive procedures, there are a few important factors to consider:
1. Hormonal Changes Can Affect Your Gums
Pregnancy hormones like progesterone and estrogen increase blood flow, which can make your gums more sensitive and prone to swelling or bleeding (a condition known as pregnancy gingivitis). This might make wearing aligners slightly uncomfortable at times.
2. Dental Scans and X-Rays
Invisalign treatment typically starts with digital scans, but sometimes X-rays are required.
While dental X-rays use very low radiation and are usually safe with proper shielding, most dentists prefer to avoid them during the first trimester. If X-rays are necessary, they can usually be postponed or adjusted to ensure safety.
3. Morning Sickness and Oral Health
If you’re experiencing morning sickness, the increased acidity in your mouth can make your teeth more vulnerable to erosion. Wearing aligners right after vomiting without rinsing your mouth can trap acid against your teeth, increasing the risk of decay. Make sure to rinse thoroughly with water or a fluoride mouthwash before reinserting aligners.
4. Dental Appointments May Be Challenging
Frequent appointments might be inconvenient, depending on how your pregnancy is progressing. If you’re dealing with fatigue, nausea, or complications, keep that in mind when committing to a treatment schedule.
Can I Start Invisalign During Pregnancy?
Yes — many women do. But there are a few practical and personal questions to consider:
Are you comfortable with dental appointments during this time?
Is your oral health in good standing?
Will aligners increase discomfort or stress?
If you’re already using Invisalign before becoming pregnant, there’s no need to stop unless advised otherwise by your healthcare provider. But if you’re considering starting while pregnant, make sure to have a thorough conversation with your care team.

Tips for Using Invisalign While Pregnant
Stay Hydrated – Pregnancy can lead to dry mouth. Drink plenty of water to stay comfortable and protect your oral health.
Brush & Floss Diligently – Hormonal changes can make gums more susceptible to infection. Clean your teeth before reinserting aligners.
Communicate with Your Providers – Keep your OB-GYN and orthodontist informed about each other’s recommendations.
Use Aligner Cleaning Crystals or Gentle Soap – Avoid harsh chemicals to clean your aligners.
Final Thoughts: Is Invisalign the Right Choice for You During Pregnancy?
In most cases, Invisalign is safe and effective during pregnancy, especially when guided by a dental professional. It’s a flexible, low-maintenance way to straighten your teeth without compromising your or your baby’s health.
If you’re in the early stages of planning a pregnancy, you might even consider starting treatment before conception — but rest assured that many expectant moms complete Invisalign treatment with no complications.
Always talk to your doctor and dentist first — and then go ahead and smile. You’re doing great.
