The objective of this phase is to ensure the teeth do not regress back to their previous position. A retainer will be used to maintain the improved position of the teeth. A retainer is a fixed or removable dental appliance which has been custom-made by the orthodontist to fit the teeth. Retainers are generally made from transparent plastic and thin wires to optimize the comfort of the patient.
Retainers are worn for varying amounts of time, depending on the type of treatment and the age of the patient. If the retainer is not worn as directed, treatment can fail or take much longer than anticipated.
The following are some of the most common types of retainers:
There are a few basics to consider for proper use and maintenance of your retainer:
Don't lose the appliance – Removable retainers are very easy to lose. It is advisable to place your retainer in the case it came in while eating, drinking and brushing. Leaving a retainer folded in a napkin at a restaurant or in a public restroom can be very costly if lost. A brightly colored case serves as a great reminder.
Don't drink while wearing a retainer – It is tempting to drink while wearing a retainer because of the unobtrusive nature of the device. However, excess liquid trapped under the trays can vastly intensify acid exposure to teeth, increasing the probability of tooth decay.
Don't eat while wearing a retainer – It can be difficult and awkward to eat while wearing a removable retainer and it can also damage the device. Food can get trapped around a Hawley retainer wire or underneath the palate, causing bad breath.
Clean the retainer properly – Removable retainers can become breeding grounds for calculus and bacteria. It is essential to clean the inside and outside thoroughly as often as possible. Hawley retainers can be cleaned with a toothbrush. Because harsh bristles can damage the PVC surface of a VFR, denture cleaner or a specialized retainer cleaner is recommended for this type of device.
