Orthodontics and Your Health UK

Yes — diabetes does not prevent orthodontic treatment, but it does require additional care. Poorly controlled blood sugar slows tissue healing and increases infection risk, which can affect how quickly teeth move and how well gum tissue responds to pressure from appliances. Most orthodontists will request confirmation that your diabetes is well-managed (ideally with a recent HbA1c result) before starting treatment. You should also maintain stricter oral hygiene and attend more frequent dental hygiene appointments during treatment. Inform your orthodontist of any changes to your diabetes management or medication during treatment.

Fixed braces that are already in place are generally safe to continue during pregnancy. Starting new orthodontic treatment is often delayed until after birth unless there is a clinical reason to proceed. X-rays should be avoided where possible during pregnancy, particularly in the first trimester — if X-rays are essential, a lead apron is used for protection. Hormonal changes during pregnancy can cause gum inflammation and increased tooth mobility, which may temporarily affect treatment progress. Inform your orthodontist as early as possible if you become pregnant during treatment so a review appointment can be arranged.

Asthma itself does not prevent orthodontic treatment. However, steroid inhalers (particularly if used without rinsing afterward) contribute to dry mouth and can increase the risk of oral thrush. Dry mouth during treatment reduces saliva's protective effect on enamel, making decay and white spot lesions more likely. Using a spacer device with inhalers and rinsing with water after each use significantly reduces these risks. Inform your orthodontist about your inhalers, as this affects the oral hygiene and monitoring plan during treatment.

Tell your orthodontist about any medical conditions, medications, allergies, and recent surgeries before treatment begins. Conditions that affect healing, bone density, gum health, or immune function can have a direct impact on orthodontic tooth movement. Blood thinners, bisphosphonates, immunosuppressants, and long-term steroid use all have specific implications. Allergies — particularly nickel or other metal allergies — affect appliance choice. You should also update your orthodontist if anything changes during treatment, including new medications, new diagnoses, or changes in health.

Yes — in many cases, bruxism and orthodontic treatment are managed simultaneously, though the approach needs to be coordinated. For fixed brace patients, grinding increases the risk of bracket debonding and enamel wear; the orthodontist monitors this at each appointment. For aligner patients, heavy grinding can crack or deform trays faster than expected; additional replacement trays may be needed. A separate occlusal splint (night guard) may be worn alongside aligners in some cases. Once orthodontic treatment is complete, bruxism should be formally managed to protect the result and long-term retention.

Active gum disease (gingivitis or periodontitis) must be treated before orthodontic treatment begins. Moving teeth through inflamed or infected periodontal tissue can accelerate bone loss and lead to irreversible damage. Once gum disease is controlled — confirmed by a dentist or periodontist — orthodontic treatment can usually proceed with more frequent hygiene monitoring during the course of treatment. Mild gingivitis is common and manageable, but moderate-to-severe periodontitis requires specialist periodontal treatment first. This sequencing is non-negotiable for your long-term dental health.
