What should I do if an Invisalign edge is cutting my gum?

If an Invisalign edge is cutting your gum, stop wearing that tray if it’s sharp or causing pain, apply orthodontic (dental) wax for temporary protection, and contact your Invisalign-trained treating clinician or Invisalign Care for evaluation, adjustment, or replacement. [4, 5]

Quick takeaways

• Stop wearing any tray that is sharp or causing pain.
• Use orthodontic wax as a temporary protective barrier until you can get professional help.
• Contact your Invisalign-trained clinician (or Invisalign Care) to have the tray evaluated, adjusted, or replaced. [4, 5]

Why stop wearing a tray that’s cutting you?

A sharp, painful or badly distorted aligner should not be worn; professional guidance classifies this as an appliance problem needing prompt clinician attention rather than continued wear. [4]

Immediate steps you can take

If the edge is rubbing or cutting, remove that tray until you can get professional help. For immediate symptom relief, press a small piece of orthodontic (dental) wax over the offending edge to create a temporary smooth barrier while you arrange contact with your provider. [5, 6]

Be cautious about accessory alterations: some accessories (for example, stickers) can fold and create sharp edges if not applied flush—check any manufacturer accessory warnings and avoid creating new sharp points. [3]

How your clinician or Invisalign Care can help

Invisalign aligners are custom trimmed to the patient’s gumline for comfort and aesthetics; definitive adjustments, trimming or replacement should be handled through your Invisalign-trained treating clinician or the Invisalign Care contact channels rather than by unsupervised home modification. [1, 2]

Some orthodontic practices offer short-term instructions (for example, smoothing a rough edge with a clean emery board or nail file) as a practice-level workaround, but this is not universal manufacturer guidance. Your clinician’s office can evaluate whether smoothing, adjusting, or issuing a replacement tray is the right solution for your situation. [5]

Using Smilo to track this issue

While you arrange clinician contact, Smilo can help you keep a simple record of wear time and when you switched or removed a tray—logging the affected tray and your out-of-mouth time can make it easier to report the problem to your provider and to track any recommended tray changes.
