Retainers After Aligners: Why You Still Need to Wear Them

You’ve just completed your teeth straightening journey with clear aligners, and your smile looks better than ever. But before you tuck away your last aligner tray and celebrate, there’s one final step you can’t skip, wearing retainers.

Retainers play a crucial role in preserving your results. Without them, your teeth can gradually shift back to their original positions, undoing all the progress made during your aligner treatment. Here's why retainers are essential and how they help maintain your straight smile long term.

Why Teeth Shift After Aligners

Even after months of wearing aligners for teeth, your smile isn’t "locked in" the moment you finish treatment. Teeth are naturally inclined to return to their previous positions due to something called orthodontic relapse. This is because:

• Your gums and bone take time to stabilise around the new position of your teeth.

• Everyday habits like chewing and speaking put pressure on your teeth.

• Ageing and jaw movements can subtly shift your bite over time.
  

That’s where retainers come in, they hold your teeth in place as your mouth adjusts, ensuring your smile stays as perfect as the day you finished your aligners.

Types of Retainers: Which One Is Right for You?

There are two main types of retainers:

• Removable Retainers: Typically made of clear plastic, these resemble your aligners and are worn overnight. They’re convenient and discreet.

• Fixed Retainers: A thin wire bonded behind your front teeth. These stay in place 24/7 and are ideal if you prefer a no-maintenance option.

At Smileie, we provide custom-fit clear retainers that are comfortable, virtually invisible, and designed to fit your post-treatment smile perfectly. You can explore our retainer options here.

How Long Do You Need to Wear Retainers?

The short answer: forever, but don’t worry, it’s not as intense as it sounds.

• First 3–6 months: Wear your retainers full-time (about 20–22 hours a day), removing them only to eat or brush.

• After 6 months: Most people can switch to night-time wear only.

• Long-term: Wearing retainers a few nights a week will likely be part of your routine for life.
  

This simple habit can help you avoid repeat treatment and keep your teeth beautifully straight without effort.

What Happens If You Don’t Wear Retainers?

Skipping your retainers, even for a few days, can cause:

• Subtle shifting you might not notice until it’s too late.

• Tightness or discomfort when trying to put retainers back on.

• Visible misalignment that might require a new aligner treatment to fix.
  

If you’ve lost or damaged your retainer, don’t wait, order a replacement immediately through Smileie’s retainer replacement service.
