Talking Invisalign: What Are the Possible Complications of This Treatment?

Invisalign clear aligners are in vogue! They’ve become a go-to alternative to traditional braces for people who want to straighten their teeth in a more discreet way. The removable trays are convenient, comfortable, and easier to clean than braces. However, like any orthodontic treatment, Invisalign can come with potential complications. Knowing what these possibilities are can set realistic expectations and help you understand when it’s time to contact your orthodontist for help.

Temporary Tooth Sensitivity

It’s common to experience some pressure or mild discomfort when switching to a new set of aligners. This happens because the trays are designed to gradually move your teeth into new positions.

The discomfort is generally temporary and often becomes easier to manage as your mouth adjusts. However, significant or persistent pain should be discussed with your dental provider.

Gum Irritation

Although Invisalign aligners are made from smooth plastic, they can occasionally rub against the gums, cheeks, or tongue. An edge that isn’t fitting properly may cause irritation or a sore spot.

Your orthodontist can check the fit and determine whether an adjustment or replacement is necessary. Don’t attempt to significantly alter the aligner yourself, as doing so could affect how it fits.

Cavities and Gum Problems

Invisalign aligners cover the teeth for much of the day, which makes oral hygiene particularly important. Wearing aligners over teeth that haven’t been properly cleaned can trap food particles and bacteria against the enamel.

Failing to brush and clean between teeth regularly can increase the risk of cavities, plaque buildup, and gum inflammation. It’s important to remove your aligners before eating and clean your teeth before putting them back in.

Bite Changes

The goal of Invisalign is to improve tooth alignment and, in many cases, the bite. However, some patients may notice that their teeth initially come together differently as treatment progresses.

If your bite feels uncomfortable, your teeth aren’t tracking with the aligners, or you notice a significant change that concerns you, contact your provider. Your treatment plan may need to be evaluated or adjusted.

Aligner Damage or Loss

Because Invisalign aligners are removable, they can be misplaced, cracked, or damaged. Pets can also be surprisingly interested in chewing on them!

Losing an aligner can interrupt your treatment schedule. If this happens, contact your dental provider rather than automatically moving to the next aligner. Your provider can tell you what to do based on your treatment plan.

Treatment May Take Longer Than Expected

Invisalign treatment depends heavily on wearing the aligners as directed, generally for 20 to 22 hours per day. Frequently removing them or not wearing them for the recommended amount of time can slow progress.

Teeth also don’t always move exactly as predicted. Some patients may require refinements or additional aligners to achieve the planned result.

Most Invisalign patients complete treatment without serious complications, but paying attention to changes in your teeth, gums, and bite is important. Good oral hygiene, following your provider’s instructions, attending scheduled appointments, and wearing your aligners as directed can help keep treatment on track.
