Those Small Elastics Have a Specific Job
Orthodontic elastics follow a prescribed pattern and schedule. Learn what to confirm, how to handle a shortage and why doubling up is not a shortcut.

The little packet looks simple. The instructions matter. Orthodontic elastics add force in a direction selected for your bite, and the connection points can differ between people. A friend's triangle pattern or a video showing both sides of the mouth is not a substitute for your own prescription.[1]
Practise the exact pattern
Ask the clinician to identify each hook and watch you place an elastic yourself. Confirm whether the instructions apply to one side or both, which packet to use and how many hours to wear them. If a diagram is supplied, keep it with the packet rather than relying on a memory of which back tooth was meant.
Say if you have a latex allergy or sensitivity. Some elastics contain latex, and the team needs that information when choosing the material. Keep the supplied packaging so you can identify the correct replacement instead of ordering a similar-looking bag online.[1]
Fresh elastics, prescribed force
The AAO recommends washing hands before handling elastics, replacing them as instructed and using fresh ones after removal. Follow your team's directions about eating and cleaning. Carry spares and contact the office before a shortage becomes several days without the prescribed elastics.[1]

Doubling up does not make missed hours disappear. The AAO warns that extra elastics can apply harmful force and slow movement. If wear has been inconsistent, tell the team what happened and ask how to resume. Do not change the pattern or add a stronger elastic to compensate.[1]
Know what needs a call
Ask in advance what to do if a hook breaks, you cannot identify a connection point or the prescribed pattern becomes impossible to use. Describe the exact problem and send a photograph only if requested. The useful question is which instruction applies now, not which improvised arrangement feels strongest.
