The clear, thermoplastic retainer is a removable appliance designed to maintain the position of your teeth after orthodontic treatment. Proper care is necessary for maintaining good oral hygiene and preserving the structural integrity of the material. Since these devices are in constant contact with the mouth, they accumulate plaque, bacteria, and tartar, which can lead to odor, cloudiness, and potential oral health issues. Following a consistent cleaning regimen is crucial to ensure the retainer remains functional and effective.
Essential Daily Cleaning Routine
The daily cleaning routine should begin immediately upon removing the retainer, while it is still wet with saliva and before debris can dry and harden onto the surface. This immediate rinsing helps remove loose plaque and food particles, preventing the formation of hardened calculus. The primary method for mechanical removal of plaque involves gently scrubbing the retainer with a soft-bristled toothbrush.
Instead of regular toothpaste, which contains abrasive particles that can scratch the plastic surface, use a non-abrasive cleaning agent. Scratches create microscopic crevices where bacteria can collect and multiply, leading to odor and cloudiness. Suitable cleaning alternatives include mild liquid dish soap or specialized cleaning solutions designed for orthodontic appliances. Always rinse the retainer thoroughly with lukewarm water after brushing to ensure no soap residue remains before reinsertion.
Protecting the Retainer from Damage
The plastic used in clear retainers is highly sensitive to elevated temperatures. Exposure to heat sources, such as boiling water, a dishwasher cycle, or being left in a hot car, can cause the material to soften and distort its custom-molded shape, a process known as warping. Even minor warping compromises the fit and prevents the retainer from holding the teeth correctly. Always use cool or lukewarm water for cleaning and rinsing to prevent this structural damage.
When the retainer is not being worn, it must be stored inside the protective case provided by your orthodontist. This prevents accidental damage from being dropped, sat on, or exposed to pets. Avoid using harsh chemicals, such as alcohol-based mouthwashes or bleach, for cleaning or soaking, as these can degrade the plastic material. While the retainer should be kept in its case, it should not be stored in a completely air-tight environment while still damp, which promotes bacterial growth and odor.
Troubleshooting Common Retainer Issues
Despite consistent daily care, plastic retainers may sometimes develop a cloudy appearance or a persistent odor, often caused by bacterial buildup or mineral deposits. For intensive cleaning, you can briefly soak the retainer in a solution of equal parts white vinegar and water for about 20 minutes. White vinegar acts as a mild disinfectant, helping dissolve mineral deposits and neutralize odors.
Specialized effervescent cleaning tablets, designed for retainers or dentures, offer another effective deep-cleaning option to address stubborn buildup. After soaking, the retainer should be brushed gently and rinsed thoroughly to remove the cleaning solution. If the retainer becomes cracked, warped, or the fit feels noticeably loose or painfully tight, contact your orthodontist right away. A damaged retainer cannot be repaired by the user and may not properly hold the teeth, necessitating a replacement.
