Wearing your retainer is arguably one of the most important parts of your treatment. If you do not wear your retainer as directed by your orthodontist, there is a chance it will not fit over time due to your teeth shifting. Your teeth naturally shift over time due to everyday actions. Whether your retainer feels snug, uncomfortable, or just won’t go in at all, there are steps you can take to fix the problem. Most importantly, don’t force it!

Instead, let’s look at why this happens and what you should do next.

Why Retainers Sometimes Stop Fitting

Even after orthodontic treatment with braces or aligners, your teeth are always on the move. That’s because of everyday habits like:
  • Eating and chewing – puts pressure on your teeth and jaw.
  • Sleeping – nighttime grinding or just resting can shift your bite.
  • Gravity – over time, it naturally affects how your teeth sit.

On top of that, if you skip wearing your retainer for a while, your teeth can shift enough to make it feel tight or impossible to wear. Sometimes, the retainer itself can warp if it’s left in a hot car, cleaned with hot water, or isn’t stored properly.

Can You Try Forcing a Tight Retainer?

Please don’t try to force your retainer in your mouth. If your retainer doesn’t fit, forcing it can cause damage to the retainer, or even your teeth. If it feels slightly snug, you can try wearing it more consistently for a few days to see if it settles back into place. But if it hurts, cracks, or just won’t go in, it’s time to call your orthodontist.

What to Do When Your Retainer Doesn’t Fit

Here’s the plan:
  1. If it’s only slightly tight – Try wearing it full time for a week and then move back to nightly wear. Sometimes your teeth just need a gentle nudge back in line.
  2. If it’s painful or won’t fit at all – Don’t force it. Call Us! Dr. Harris will check your teeth and retainer, then recommend the best solution, whether that’s an adjustment, a new retainer, or another treatment option.

Why Wearing Your Retainer Is So Important

Your retainer is the key to keeping your smile straight after orthodontic treatment. Without it, your teeth can slowly shift back to where they were before braces. Retainers “hold the line,” allowing your teeth, jawbone, and ligaments to stabilize in their new positions. Wearing it consistently protects the investment you made in your smile.
