Fixed braces some FAQs

Fixed braces some FAQs

While there are different brands of fixed braces, they work in the same way and common issues crop up. Read on to find out the answers to some commonly asked questions which arise for patients in fixed braces.

Fixed braces some FAQs - Protruding Wire

Protruding Wire

Occasionally, the end of a wire will work itself out of place and irritate the mouth. Use a Cotton bud or pencil eraser to push the wire so that it is flat against the tooth. If the wire cannot be moved into a comfortable position, cover it with relief wax (see irritation of lips or cheeks above for instructions on applying wax).

In a situation where the wire is causing extreme pain and you are not able to see the orthodontist soon, you may, as a last resort, snip off the protruding wire using a sharp pair of nail scissors or clippers. To reduce the possibility of swallowing the snipped piece of wire, use a folded tissue or gauze around the area. Use a pair of sharp nail scissors or clippers to snip off the protruding wire. Relief wax may still be necessary to provide comfort to the irritated area.

Fixed braces some FAQs - Loose Brackets, Wires or Bands

Loose Brackets, Wires or Bands

If the braces have come loose in any way, the orthodontist should be called to determine appropriate next steps.

Brackets are the parts of braces attached to teeth with a special adhesive. They are generally positioned in the centre of each tooth. The bracket can be knocked off if hard or crunchy foods have been eaten.

If the loose bracket has rotated on the wire and is sticking out and you cannot immediately reach the orthodontist, you can do a temporary fix to ease discomfort and prevent further damage. This must only be done as a last resort. Take care to prevent swallowing or other injury.
To put the bracket back in place, use clean tweezers to slide the bracket along the wire until it is between two teeth. Rotate the bracket back to the proper position, then slide it back to the centre of the tooth.

Fixed braces some FAQs - Ligatures Come Off

Ligatures Come Off

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

When one ligature pops off or breaks, others may follow. Examine all ligatures adjacent to the missing ligature. Please notify your orthodontist to check whether the ligature needs to be replaced.

Mouth Sores

Some patients are susceptible to episodes of mouth sores. While braces do not cause them, they may be made worse by an irritation from braces. One or several areas of ulceration of the cheeks, lips or tongue may appear. This is not an emergency, but may be very uncomfortable. Prompt relief may be achieved by applying a small amount of topical anaesthetic (such as Bonjela® or Brace Relief) directly to the ulcerated surface using a cotton swab. Re-apply this when needed or as directed by the instructions on the product.

Fixed braces some FAQs - Irritation of Lips or Cheeks

Irritation of Lips or Cheeks

Sometimes new braces can be irritating to the mouth, especially when eating. A small amount of non-medicinal relief wax makes an excellent buffer between brace 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. Eating will then become more comfortable (avoid hot drinks as this will melt the wax). If the wax is accidentally ingested, it’s not a problem as the wax is harmless.


It is quite normal to experience discomfort for a day or two after braces or retainers are fitted/adjusted. It can make eating uncomfortable - the discomfort is both normal and temporary. Keep to eating soft foods. The use of a mild analgesic such as Ibruprofen or paracetamol is advised for the first few days if discomfort is experienced.

Fixed braces some FAQs - Food Caught Between Teeth

Food Caught Between Teeth

This is not an emergency, but can be a little uncomfortable. It is easily fixed with 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.
