In most cases braces or aligners can continue safely throughout pregnancy, but there are clinical considerations around x-rays, gum changes, and treatment timing that are worth understanding before you begin or continue.

Yes — continuing orthodontic treatment that is already underway is generally safe throughout pregnancy. Fixed braces, clear aligners, and retainers do not present any direct risk to the pregnancy. The physical forces applied to teeth are localised and do not affect the uterus, placenta, or foetal development. The main clinical consideration is not the orthodontic appliance itself but the changes that pregnancy causes in the mouth — particularly to the gums — and the need to avoid routine x-rays during the first trimester. ## How pregnancy affects your gums and teeth Pregnancy hormones — primarily progesterone and oestrogen — cause increased blood flow to gum tissue and alter the immune response in ways that make gums more susceptible to inflammation. This condition, called pregnancy gingivitis, affects the majority of pregnant patients to some degree and typically begins in the second month, peaks in the eighth, and resolves after delivery. Gums become more swollen, sensitive, and prone to bleeding. In patients with fixed braces, maintaining good oral hygiene becomes more important than usual, and more frequent hygienist appointments may be recommended. Left unmanaged, pregnancy gingivitis can progress to periodontitis, which has been associated with adverse pregnancy outcomes in some studies. ## Starting new orthodontic treatment during pregnancy Starting a new course of treatment during pregnancy is more complex than continuing existing treatment. Routine orthodontic records include dental x-rays, which are best avoided in the first trimester and approached with lead shielding and minimal exposure thereafter. Some orthodontists prefer to delay starting new comprehensive treatment until after delivery, particularly where records would require multiple x-rays. However, for patients with clear clinical need or who are part-way through treatment planning, starting with a modified records approach (fewer x-rays, use of digital scans) is a reasonable option. Discuss timing and the records process with your orthodontist early in the pregnancy. ## X-rays during pregnancy Standard dental x-rays during orthodontic treatment involve very low radiation doses, and modern digital x-rays produce significantly lower doses than older film-based systems. The risk to a developing foetus from properly shielded dental x-rays is extremely small. However, by convention, routine x-rays are generally avoided in the first trimester when organogenesis is occurring, and kept to the minimum clinically necessary during the second and third trimesters. Emergency x-rays — where a clinical problem requires imaging to manage safely — are appropriate at any stage with appropriate shielding. For routine orthodontic records, your orthodontist will typically use digital scans and photographs where possible to minimise any x-ray exposure. ## Aligner treatment during pregnancy Clear aligner treatment (Invisalign and similar systems) is particularly compatible with pregnancy because the aligners can be removed for cleaning, do not trap food around brackets, and make gum hygiene easier to maintain than fixed braces. The main practical consideration is that aligner treatment requires compliance — wearing aligners for 20 or more hours per day — which can be affected by nausea in the first trimester. If morning sickness is severe, aligner wear may temporarily reduce and treatment may progress more slowly. Inform your aligner provider if compliance is affected so the treatment plan can be adjusted. ## After delivery: resuming or starting treatment Many patients choose to delay starting orthodontic treatment until after the baby is born and initial recovery is complete. This avoids the x-ray and gum considerations and allows treatment to begin from a stable baseline. If you were mid-treatment during pregnancy and took a break, or if treatment was delayed, your orthodontist will take new records and assess any changes to tooth position before resuming. Breastfeeding does not affect orthodontic treatment; the forces applied to teeth do not produce substances that transfer to breast milk. ## Practical advice for pregnant patients with braces If you are pregnant and in orthodontic treatment, tell your orthodontist as early as possible. Increase the frequency of your oral hygiene routine — brush after every meal if possible, floss daily, and use a fluoride mouthwash. Book a hygienist appointment in the second trimester if you have not had one recently. Attend all scheduled orthodontic adjustment appointments; missed appointments during pregnancy can extend treatment time. If your gums become very swollen or painful, contact your orthodontist and dentist — this is manageable and should not be left until after delivery. ## Useful related pages [Adult orthodontics](https://virtualconsultant.online/adult-orthodontics-decision-guide) [Orthodontic retainers](https://virtualconsultant.online/guides/orthodontic-retainers-uk) [Invisalign UK guide](https://virtualconsultant.online/invisalign) [Fixed braces guide](https://virtualconsultant.online/treatments/braces) [Long-term retention](https://virtualconsultant.online/long-term-orthodontic-retention) This guide is for general information only.

Aligner treatment requires dental scans and in some cases x-rays for initial records. Most orthodontists prefer to avoid routine x-rays in the first trimester. Aligner wear compliance may also be affected by first trimester nausea. Starting in the second trimester is common for patients who want to begin treatment during pregnancy. Many patients prefer to wait until after delivery for a fresh start with a full set of records. Will pregnancy make my teeth move? Pregnancy does not directly cause teeth to move. However, the gum changes associated with pregnancy — particularly if gingivitis develops around fixed braces — can affect the health of the supporting structures. Gum disease over time does contribute to tooth movement and looseness, which is why managing pregnancy gingivitis is important. Teeth can also feel slightly more mobile during pregnancy due to changes in the periodontal ligament from hormones, but this is usually temporary and resolves after delivery. Is it safe to have a dental x-ray while pregnant? Modern digital dental x-rays produce very low doses of radiation. A full set of orthodontic records x-rays delivers a fraction of the natural background radiation a person receives in a single day. With appropriate lead shielding over the abdomen and thyroid, the risk to the foetus is extremely small. However, routine x-rays are conventionally avoided in the first trimester, and kept to the minimum clinically necessary thereafter. Emergency dental x-rays are appropriate at any stage when clinically needed. Do I need to tell my orthodontist I am pregnant? Yes — inform your orthodontist as early as possible. This allows them to adjust your appointment schedule to avoid routine x-rays in the first trimester, plan for potential gum changes, and discuss whether any modification to your treatment timing or approach is appropriate. Your orthodontist cannot make informed clinical decisions about your care without knowing you are pregnant. Can I wear a retainer during pregnancy? Yes. Wearing a retainer during pregnancy is safe and important — particularly if you have completed active orthodontic treatment. Pregnancy gum changes can slightly affect tooth position, and consistent retainer wear helps prevent any drift. If your retainer feels uncomfortable due to gum swelling, see your orthodontist rather than stopping wear entirely. Should I pause treatment during pregnancy? For most patients in existing treatment, continuing is the better clinical choice. Pausing treatment allows teeth to drift back and extends total treatment time. Unless there is a specific clinical reason — such as needing multiple x-rays that cannot be deferred — continuing treatment throughout pregnancy is generally recommended. Discuss your specific situation with your orthodontist rather than assuming treatment should stop. Explore your options Quick links Not sure where to start?
