Pregnancy often brings questions about which medical procedures remain safe, and orthodontic treatment is a common concern. Many individuals successfully undergo teeth straightening with braces or aligners throughout their pregnancy, but the process requires careful coordination. The materials used in orthodontic appliances are generally safe and pose no known risk to the developing fetus. However, the physiological changes of pregnancy necessitate significant adjustments to care. It is important to discuss your plans with both your obstetrician and your orthodontist to ensure a tailored and safe treatment protocol.
Feasibility of Starting or Continuing Braces
The physical appliance itself, whether traditional braces or clear aligners, is not inherently dangerous to a pregnancy, as the metals and plastics used do not transmit harmful effects to the developing baby. For those who become pregnant while already in treatment, continuing with regular adjustments is typically safe and recommended.
However, the question of starting new treatment is often approached with more caution by orthodontists. Many practitioners prefer to delay the initiation of new braces until the second trimester or even until after delivery. This preference is primarily due to the diagnostic procedures, such as X-rays, and the potential discomfort of the first trimester. If a full set of diagnostic images was taken before conception, starting treatment is generally less complicated.
Physiological Changes Affecting Oral Health
Pregnancy hormones, particularly the dramatic increase in estrogen and progesterone, significantly alter the oral environment. This hormonal surge increases blood flow to the gums, making the tissue much more reactive to the presence of plaque. This heightened sensitivity often leads to pregnancy gingivitis, characterized by swollen, reddened, and easily bleeding gums.
For patients with braces, this inflammatory response is exacerbated because the hardware creates additional surfaces where plaque can accumulate. The hormones can also temporarily affect the periodontal ligaments, which hold the teeth in the jawbone. This effect can sometimes result in a slight increase in tooth mobility, making the gums more vulnerable to irritation from the braces.
Another challenge is the increased risk of tooth decay and enamel erosion. Morning sickness, which involves frequent exposure to stomach acid, can wear down the protective enamel layer of the teeth. Additionally, changes in diet, such as increased cravings for sugary or acidic foods, can further increase the risk of cavities. Maintaining exceptional oral hygiene becomes necessary to prevent these issues from worsening.
Clinical Modifications and Safety Protocols
The primary modifications to orthodontic care during pregnancy revolve around minimizing exposure to radiation and controlling medication use. Most orthodontists avoid new radiographs unless absolutely necessary for diagnosis or managing a severe complication, even though a single dental X-ray poses a negligible risk to the fetus. If X-rays are required, protective lead aprons are used, and the dosage is kept as low as reasonably achievable. Initial treatment planning may rely on older scans to avoid new exposure, especially during the first trimester.
Medication management is another area of strict protocol, with orthodontists consulting the patient’s obstetrician before prescribing any drugs. Pain relief options are limited, and over-the-counter medications like acetaminophen are generally preferred for discomfort following adjustments. Non-steroidal anti-inflammatory drugs (NSAIDs) and certain antibiotics are typically avoided or used only with specific clearance due to potential risks. Local anesthetics, such as those used for minor procedures, are generally considered safe throughout the pregnancy.
Logistical adjustments are also made to ensure patient comfort during appointments, particularly in the later stages of pregnancy. Longer procedures are often broken into shorter sessions to prevent discomfort from remaining in one position for too long. In the third trimester, the patient may be positioned with her right side slightly elevated to prevent the uterus from compressing the inferior vena cava. Patients are also advised to schedule more frequent professional cleanings and maintain a meticulous daily hygiene routine to counteract the heightened risk of gingivitis.
