Why Did Your Retainer Snap While You Slept?


If your retainer snapped while you slept, the choice of retainer cleaner is worth considering. Opt for a persulfate-free retainer cleaner to address potential issues. Traditional cleaners may contribute to the weakening of retainers, possibly causing them to snap. Choosing a purple cleaner tablet is a simple step to ensure effective cleaning and reduce the risk of your retainer snapping during sleep.

In this article, we will delve into the various factors that can contribute to retainer breakage during slumber and provide insights into how to prevent it from happening.

1. Nighttime Teeth Grinding (Bruxism)

One of the primary reasons retainers break during sleep is nocturnal teeth grinding, also known as bruxism. Bruxism involves the clenching or grinding of teeth during sleep, and this force can be significant. The pressure exerted on your retainer can cause it to crack or snap over time. To address this issue, your orthodontist may recommend a nightguard, a special device that cushions your teeth and prevents direct contact between your retainer and your teeth.

2. Retainer Material Quality

The material your retainer is made from plays a crucial role in its durability. If your retainer is made from low-quality or aged material, it may become more brittle over time, making it susceptible to breaking. High-quality retainers, such as those provided by orthodontic professionals, are designed to withstand daily wear and tear, including nighttime use.

3. Incorrect Retainer Care

Improper care and maintenance of your retainer can also contribute to its breakage. If you fail to clean your retainer regularly, bacteria can accumulate, weakening the material. Additionally, exposing your retainer to high temperatures, like hot water or direct sunlight, can cause it to warp or become more fragile. Ensure you follow your orthodontist's care instructions to maintain your retainer's integrity.

4. Accidental Biting

Sometimes, you might accidentally bite down on your retainer while asleep. This can happen if your retainer isn't properly seated or if it's designed in a way that allows for contact with your teeth. To minimize the risk of accidental biting, ensure your retainer is correctly positioned, and if you notice discomfort or irritation, consult your orthodontist for adjustments.

5. Aging and Wear

Retainers, like any orthodontic appliance, have a lifespan. Over time, the materials may weaken or degrade naturally. If you've had your retainer for a long time, it might be more prone to breaking. Regular check-ups with your orthodontist can help identify signs of wear and allow for timely replacements.

6. Physical Trauma

In some cases, retainer breakage during sleep might result from physical trauma, such as accidentally dropping your retainer on a hard surface or applying excessive force when cleaning it. Always handle your retainer with care, and avoid exposing it to situations where it could be damaged.


Discovering a broken retainer in the morning can be frustrating, but understanding why it happened can help you prevent it in the future. Nighttime teeth grinding (bruxism) is a common cause, and using a nightguard can mitigate this risk. Ensure your retainer is made from high-quality materials, follow proper care instructions, and be mindful of accidental biting. Additionally, be aware that retainers have a lifespan, so regular check-ups with your orthodontist are essential to identify signs of wear and tear.
