If you swallow or aspirate an orthodontic appliance, firstly contact your orthodontist Dr. James Noble to manage the situation.

Here is an article that Dr. Noble wrote for general dentists on managing patients who have swallowed their braces, Invisalign retainers or other orthodontic appliances, enjoy!

Context

Patients receiving orthodontic treatment are at a very high risk of having appliances swallowed into the oropharynx during treatment due to the small size of brackets and clipped wires. Orthodontic appliances that can be swallowed include wires, brackets, transpalatal arches, temporary skeletal anchorage devices, and keys for expanders and removable appliances among others.

Foreign bodies entering the alimentary canal rarely represent a serious medical issue as they pass through the gut wall uneventfully. In some instances, a foreign body may result in impaction or perforation of the gut wall. Foreign bodies entering the airway pose much more serious consequences.

Signs & Symptoms

Loose appliance: The patient’s orthodontist must be notified immediately for recementation or replacement.
Aspired appliance:
- Excessive coughing, difficulty breathing, and increased congestion or noisy breathing
- Patient choking or gagging, runny nose or watery eyes
- Dusky bluish or red changes in the face, on or under the eyes or around the mouth
Large object swallowedinto the alimentary canal:
- Difficulty, inability. or pain when swallowing
- Muscle incoordination
- Haematemesis and/or vomiting

Investigation

Perform a complete intraoral exam.
Look for an ulcer that may develop on the mucosa and may have the potential to cause an infection.
Look for an irritation of the mucosa of the inner cheek.
Look for the orthodontic bracket, wire, or appliance that may be dislodged.
Ask the patient if they swallowed it similar to how they swallow food or if they coughed or choked when they swallowed it.

Diagnosis

Based on the intraoral examination, it is determined that a long wire may be irritating the mucosa or a broken bracket may be detached.

Treatment

If aspiration is suspected, referral to the ER or an orotolaryngologist is indicated.
Rule out obstruction of the larynx or the trachea.
If a large foreign body is trapped above the vocal cords, respiratory distress can occur and urgent care is needed, involving back blows and the Heimlich maneuver.
Ask the patient to keep calm, turn their head down and attempt to cough excessively. Stridor is also a common sign.
If the object passes through the airway without obstruction, refer the patient to a hospital for immediate medical attention.
If the object is still trapped, the dentist or a team member should call 911:
- Maintain positive airway pressure with CPR until the paramedics arrive.
- Explain the situation to the paramedics.

Recommendations to mitigate the risk of foreign objects ingestion or inhalation

Attach floss to appliances and objects when appliances are being cemented and placed intra-orally.
Use a barrier, such as gauze, when adjusting orthodontic appliances or placing brackets.
Use radio-opaque acrylic, if possible, to radiographically visualize appliances that are swallowed or aspirated.
Tether bands with an adequate length of floss through the molar tubes during banding procedures, especially for second molars.
Cinch the archwire whenever possible.
Reinforce removable quad-helices and transpalatal arches at the point of attachment by using elastomeric ligatures or, preferably, stainless steel ligatures.
Micro-implants must be adequately attached by steel ligatures to the main appliance.
Advise patients not to try to reseat damaged, ill-fitting, or broken fragments of any appliance. Instead, they should return to the orthodontist to have the appliance checked.
