Pregnancy changes a lot; your routine, your energy, and sometimes even your smile.
So if you’ve been thinking about getting clear aligners, it’s only natural to ask: Can you use clear aligners while pregnant?
The short answer is yes, you usually can. With the right guidance from your dentist and the right aligner system, it can be a comfortable, safe, and surprisingly easy process.
Clear Aligners and Pregnancy: How They Work Together
Clear aligners are an alternative to braces that use a series of thin trays to move your teeth gently over time. For adults, they’re especially appealing because they’re discreet, easy to remove, and fit right into a busy lifestyle.
During pregnancy, hormonal changes can make your gums more sensitive or prone to swelling.¹ That doesn’t make aligners unsafe, it simply means your dentist will monitor your gum health closely and ensure every aligner continues to fit comfortably.
Starting Aligners During the First Trimester
If you’re in your first trimester and battling morning sickness or fatigue, your dentist might suggest waiting a few weeks before starting. The goal is comfort, not rushing.
OrthoFX aligners are made from BPA-free, medical-grade materials, so they’re perfectly safe to use once you’re ready. Beginning treatment when you feel settled makes it easier to stay consistent with daily wear and care.
So, can you use clear aligners while pregnant in the first trimester? Yes, you can, as long as your dentist approves.
Second Trimester: The Sweet Spot for Starting Treatment
Most expectant moms find their second trimester to be the smoothest part of pregnancy. You have more energy, fewer symptoms, and a steadier routine. It’s also a great time to start or continue your aligner journey.
The second trimester is usually the most comfortable window for dental appointments and orthodontic check-ins.² The early nausea of the first trimester has eased, and the physical discomfort of the third trimester hasn’t set in yet. You’re more settled into your routine, which makes it easier to visit your dentist, handle adjustments, and stay consistent with your aligner plan.
Third Trimester and Beyond
Can you use clear aligners while pregnant in the third trimester? Absolutely.The only challenge is keeping up with appointments when your schedule fills up.
That’s where OrthoFX simplifies everything.
The FXOnTrack app connects you with your dentist through secure remote monitoring. You can send quick photos or updates, and your doctor can let you know exactly when an in-office check is needed, or when you can stay home and keep progressing.
Less travel, less stress, and more confidence that your smile is moving in the right direction.
