Plastic retainers are prone to cracking due to wear and tear, accidents, improper care, and exposure to heat. Even with proper care, plastic retainers can crack or break, requiring repair or replacement. Identifying cracks in a retainer can be challenging, but some signs include mouth soreness, bite issues, and discomfort. Temporary fixes such as dental wax or adhesive can be applied to minor cracks, but professional attention is necessary to ensure proper repair and prevent further issues. Orthodontists can repair or replace cracked retainers, ensuring optimal oral health and maintaining the results of orthodontic treatment.

What You'll Learn
Poor storage and accidental damage
Poor Storage
Retainers should always be stored in their protective case when not in use. This helps to prevent accidental damage and shields them from environmental damage. For example, if you misplace your retainer and it ends up beside your bed, you might accidentally step on it and crack it. Dogs and other animals may also be attracted to the smell of retainers and chew on them if they find them.
Accidental Damage
Accidents happen, and sometimes they involve your retainer. Dropping your retainer on a hard surface, stepping on it, or bending it can lead to cracks or fractures. Biting down on something unexpectedly hard can also damage your retainer, leaving it cracked or weakened.
To prevent accidental damage, always use both hands when putting in or removing your retainer, and handle it gently to avoid unnecessary stress. Avoid bending or dropping your retainer, and keep it away from hot water, car dashboards, or other sources of heat, as this can warp and weaken the plastic.

Exposure to heat
Plastic retainers are sensitive to temperature changes. Exposure to heat sources like hot water, car dashboards, or leaving them in a hot car can warp the plastic, making it more brittle and prone to breakage. Warping can also cause an uncomfortable fit, with the retainer feeling too tight or too loose in certain areas. In addition, hot water can further distort or damage the retainer, and even cause it to crack.
To prevent warping and cracking, always store your retainer in a protective case when not in use. Avoid storing it in areas exposed to heat or direct sunlight, such as on a windowsill or car dashboard. When cleaning, use lukewarm or warm water, never hot, to avoid damaging the plastic.
If your retainer has been exposed to excessive heat and is now warped or cracked, it is important to consult your orthodontist for advice. They can assess the damage and recommend a suitable solution, such as repairing or replacing the retainer. Temporary fixes, such as dental wax, can be used to hold the retainer together until you can visit your orthodontist for a permanent solution.

Improper cleaning
Firstly, it is important to use the correct products to clean your retainer. Avoid using toothpaste or harsh chemicals, such as mouthwash, as these can weaken the plastic and make it more prone to cracking. Instead, opt for a mild, non-abrasive cleaning solution designed for retainers, such as retainer cleaning tablets.
When cleaning your retainer, ensure you are thorough and cover all areas. Use a soft-bristled toothbrush to gently brush away debris and plaque. Avoid using harsh scrubbing motions, as this can also weaken the material over time and lead to cracks. It is recommended to brush your retainer daily and to soak it in a clear tablet solution weekly to avoid staining. Always use lukewarm water for rinsing, brushing, or soaking your retainer, as hot water can warp or distort plastic retainers, potentially altering their fit and making them more prone to cracking.
In addition to using the correct products and techniques, it is important to clean your retainer regularly. Skipping regular cleaning can allow bacteria and plaque to build up, leading to irritation, bad breath, and even damage to your teeth and gums.

Lack of resin
One of the reasons why retainers crack is due to a lack of resin. The American Association of Orthodontists Journal states that inadequate resin abrasion leads to retainer failure. While small cracks in the acrylic base can be repaired by adding more acrylic material or dental resin, large or multiple cracks reduce the structural integrity of the retainer.
Orthodontic-safe adhesives or dental resins can be used to repair cracked retainers. The process involves sanding the cracked area with fine-grit sandpaper or an emery board to create a rough surface for better adhesion. A thin layer of the adhesive is then applied, ensuring it covers the entire crack and extends slightly beyond it. Once the adhesive has cured, the repaired area is smoothed with fine-grit sandpaper to remove any excess.
It is important to note that repairing cracked retainers is not always straightforward, and minor cracks can sometimes be challenging to fix. In such cases, orthodontists may recommend replacing the retainer to ensure its effectiveness and precise fit.
To prevent cracks and extend the lifespan of retainers, proper care and maintenance are essential. This includes handling retainers gently, especially when inserting or removing them, and storing them in a protective case when not in use. Regular check-ups with an orthodontist and proper cleaning with mild soap and warm water or persulfate-free retainer cleaning solutions can also help prevent cracks caused by bacterial buildup and material fatigue.
Additionally, users should avoid chewing hard foods or biting down on the retainer, as this can place undue stress on the appliance, increasing the risk of cracking. Exposure to high heat and harsh chemicals should also be avoided, as they can weaken the retainer material.

Material fatigue
Plastic retainers are susceptible to material fatigue, which can cause them to crack or break over time. Material fatigue occurs due to several factors, including wear and tear, accidents, improper care, and exposure to high temperatures.
Wear and tear is a common cause of material fatigue in plastic retainers. Over time, the plastic and wires in retainers may weaken and become more prone to cracking. This can be exacerbated by biting down on hard substances or chewing hard foods while wearing the retainer, as this can put additional stress on the material.
Improper care of plastic retainers can also contribute to material fatigue. For example, using harsh scrubbing motions or abrasive toothpaste when cleaning the retainer can weaken the material over time, making it more susceptible to cracking. In addition, improper cleaning can lead to bacterial buildup, which can further weaken the structure of the retainer.
Exposure to high temperatures is another significant factor in material fatigue. Excessive heat can warp and weaken plastic retainers, making them more likely to crack. This includes exposing the retainer to hot water, leaving it in a hot car, or placing it on a car dashboard.
To prevent material fatigue and reduce the risk of cracking, it is important to handle plastic retainers with care. This includes always using both hands when putting in or removing the retainer and storing it in a protective case when not in use. Regular orthodontic check-ups can also help identify any signs of wear and tear before they lead to more significant problems.
While minor cracks in plastic retainers may be temporarily repaired at home, it is important to consult an orthodontist for a permanent solution. They can assess the damage and recommend the best course of action, ensuring the retainer continues to serve its purpose effectively.

Frequently asked questions
Plastic retainers can crack due to several reasons, including wear and tear, improper removal, improper handling while cleaning, biting or chewing on the retainer, accidents, and age.
Incorrect removal can put unnecessary strain on your retainer, which can lead to cracking or breaking over time. To correctly remove your retainer, use one finger on each side to prevent flexing and twisting as you pull it out of your mouth.
Holding the retainer incorrectly during the cleaning process can put stress on your retainer and lead to cracks. When brushing the retainer, ensure that you support it in your hand or on a towel and apply even pressure throughout to prevent flexing.
Yes, biting or chewing on your retainer can contribute to cracks. This habit places undue stress on the appliance, increasing the risk of damage.
If your retainer cracks, you should stop wearing it to avoid possible injuries to your gums and teeth. Contact your orthodontist for guidance on repair or replacement, and do not attempt to fix the crack with glue or other adhesives, as these may contain toxic chemicals.
