Emergency Treatments At Home

Only the most severe emergencies may require immediate attention by an orthodontist. The majority of these are easily treated at home with a follow-up by the patient’s orthodontist.

Mouth Sores

Some patients are susceptible to episodes of mouth sores. While braces do not cause them, the mouth sores may be precipitated or exacerbated by an irritation. One or several areas of ulceration of the lips or tongue may appear. This is not an emergency, but may be very uncomfortable for the patient. Prompt relief may be achieved by applying a small amount of topical anesthetic (such as Orabase or OraGel) directly to the ulcerated surface using a cotton swab. Instruct the patient to reapply as needed.

Food Caught Between Teeth

This is not an emergency, but can be a little uncomfortable or embarrassing for the braces-wearing patient. It is easily fixed with a piece of dental floss. Try tying a small knot in the middle of the floss to help remove the food, or use an interproximal brush or toothpick to dislodge food caught between teeth and braces.

Ligatures Come Off

Tiny rubber bands or small, fine wires, known as ligatures, hold the wire into the bracket.  If a rubber ligature should come off, you may be able to put it back in place using sterile tweezers. If a wire ligature comes loose, simply remove it with sterile tweezers. If the wire ligature is stick­ing out into the lip but is not loose, it may be bent back down with a Q-tip or pencil eraser to eliminate the irritation.

Of course, when one ligature pops off or breaks, others may follow. Be sure to examine all liga­tures. Missing or broken ligatures should be brought to the attention of the orthodontist.

Irritation of Lips or Cheeks

Sometimes new braces can be irritating to the mouth, especially when the patient is eating. A small amount of non-medicinal relief wax makes an excellent buffer between metal and mouth. Simply pinch off a small piece and roll it into a ball the size of a small pea. Flatten the ball and place it completely over the area of the braces causing irritation. The patient may then eat more comfortably. Let the patient know that if the wax is accidentally ingested, it’s not a problem as wax is harmless.

Loose Brackets, Wires or Bands

If the braces have come loose in any way, the parent/guardian needs to be notified, and they should call the orthodontist to determine appro­priate next steps.

Brackets are the parts of braces attached to teeth with a special adhesive. They are generally positioned in the center of each tooth. The bracket can be knocked off if the patient has eaten one of those hard or crunchy foods ortho­dontic patients are instructed to avoid, or if the mouth is struck while at play. (We encourage all patients, especially those with braces, to wear a protective mouth guard while playing sports.)

If the bracket is off center, the adhesive may have failed. Inform the parent/guardian, and then inform the orthodontist.

If the loose bracket has rotated on the wire and is sticking out and the patient cannot immediately be taken to the orthodontist, you can perform a temporary fix to alleviate discomfort and prevent further damage. But take care to prevent swallowing or other injury.

To put the bracket back in place, use sterile tweezers to slide the bracket along the wire until it is between two teeth. Rotate the bracket back to the proper position, and then slide it back to the center of the tooth.

If a rubber or wire ligature is lost, notify the parent/ guardian and phone the orthodontist who may advise whether the patient should be seen.

Protruding Wire

Occasionally, the end of a wire will work itself out of place and  irritate the patient’s mouth.

Use a Q-tip or pencil eraser to push the wire so it is flat against the tooth.  If the wire cannot be moved into a comfortable position, cover it with relief wax and make the orthodontist aware of the problem. If the wire is extremely bothersome, and the patient will not be able to see the orthodontist, you may, as a last resort, clip the wire.

Reduce the possibility of the patient swallowing the snipped piece of wire by using folded tissue or gauze around the area. Use a pair of sharp clippers and snip off the protruding wire. Relief wax may still be necessary to provide comfort to the irritated area.

Piece of Appliance is Swallowed

This is rare, but when it does happen, it can be fairly alarming to the patient. Encourage the patient to remain calm. If you are able to see the piece, you may carfully attempt to remove it. But do not make the attempt if you could cause harm. If the patient is coughing excessively or having difficulty breathing, the piece could have been swallowed or aspirated. If you are unable to see the piece and believe it may have been aspirated, notify the parent/guardian and the orthodontist immediately.

If appropriate, under the circumstances, examine the patient’s braces for problems that may resulted from the missing piece, such as looseness or irritation, and treat as specified above.
