When braces are first applied, a person might not feel pain or discomfort right away. However, within a few hours, the gentle pressure exerted by the braces begins to take effect. This pressure gradually moves the teeth into alignment, which can cause pain and discomfort lasting from a day or two up to a week.

During the first week, some common experiences may include:

- Sore gums

- Scrapes or sores on the inside of the cheeks from the metal brackets

- Potential cuts on the tongue if the person touches the braces with their tongue

- Sore teeth, particularly when eating

As time goes on, the discomfort from the braces typically lessens as the body adjusts. However, to continue the alignment process, an orthodontist needs to periodically tighten the braces.

When braces are tightened, the orthodontist may:

- Replace the wires

- Adjust or add springs

This tightening usually occurs once a month or as needed, based on the individual's progress. After tightening, the discomfort experienced is often similar to the initial pain felt when the braces were first applied, though it may be less intense. At this stage, most people primarily feel discomfort in their teeth and gums, while the cheeks and tongue, having adjusted to the braces, are less likely to develop new abrasions.
