Many people overlook the fact that retainers do not last forever. Like any dental appliance, they can wear down, warp, or break over time. So, how often to replace retainers? In this blog, we’ll explore how long do retainers last, what affects their durability, and how you can make the most of them. If you're wondering when to get a new retainer or noticing signs of retainer wear and tear, keep reading. This guide covers it all.
Types of Retainers and Their Average Lifespan
Retainers are custom-made dental devices designed to help keep your teeth in their new, straight positions after you have finished orthodontic treatment like braces or aligners. Wearing your retainer as instructed helps stop your teeth from gradually moving back to their original positions—a process known as orthodontic relapse .
Not all retainers are created equal. Your choice of retainer, based on your lifestyle, comfort, and orthodontic needs, can greatly influence its durability and replacement frequency. Read further to know the types and retainer lifespan.
Hawley Retainers

Made of acrylic and metal wires, Hawley retainers are long-lasting, durable, and adjustable. They are often recommended for their durability and ease of repair.
- Retainer lifespan: 5–10 years (with proper care)
Clear Plastic Retainers

Clear retainers, also known as Essix retainers, are nearly invisible and comfortable, making them a favorite for those who want a low-profile look. They’re also easier and more comfortable to wear.
- Retainer lifespan: 6 months to 2 years
Some providers like ALIGNERCO offer affordable clear retainers as part of their aligner treatment to ensure you retain the results you have achieved.
Permanent Retainer

Permanent retainers are also known as bonded retainers. They are attached to the back of your teeth and stay fixed in place 24/7. While they are not visible, they can be harder to clean and may need repair over time.
- Retainer lifespan: Can last up to 20 years, depending on dental hygiene and wear
Factors That Affect Retainer Lifespan
Several variables impact how long your retainers last, including:
- Oral hygiene habits: Poor cleaning can lead to plaque buildup or discoloration of your retainer.
- Teeth grinding: Teeth grinding, or bruxism , can distort or damage the retainer over time.
- Storage and care: Exposing retainers to heat or not using a protective case reduces their lifespan.
Signs You Need a New Retainer
No matter how well you take care of them, all retainers will eventually wear down over time. Knowing when to get a new retainer can save you from the cost and time of undergoing orthodontic treatment again. Here are key signs that might indicate you need to replace your retainer:
Poor Fit or Discomfort
If your retainer suddenly feels too tight, too loose, or just uncomfortable, it’s a sign that something’s not right. A proper fit is crucial, and ignoring this can undo all the progress you’ve made with orthodontic treatment.
Visible Retainer Wear and Tear
Cracks, bending, or warping are clear signs that your retainer needs to be replaced. For plastic retainers, this kind of wear and tear often comes from habits like teeth grinding or chewing on the retainer.
Persistent Odor or Discoloration
Even after cleaning, if you experience a bad odor from your retainer, or it appears discolored or stained, it may be harboring bacteria, which can cause these issues. These are the indicators that it's time to replace your retainer.
Your Teeth Begin to Shift
It is one of the most obvious signs. If your teeth start to shift back to their original misaligned state, it indicates your retainer is no longer doing its job.
