Once the active period of alignment is completed, the braces are removed and retainers are made to hold teeth in their new positions while the gums, bones, etc. settle into “their” new positions. As children continue to grow, their facial structure may also change. If so, a retainer can be used to keep the teeth in alignment during this growth period. For adults, their facial structure also changes as they age and a retainer can be worn to keep the teeth aligned.
You must wear your retainer(s) faithfully as teeth continue to move and shift throughout life as the tissues supporting them change. Retainers that are in the mouth will not be lost or broken (or eaten by animals wild or domestic)..
Care of your Retainers is very vital to ensure long lasting retainers When brushing your removable retainer you are to only use cold water and hand soap. You can also use a denture cleaning tablet and soak it in luke warm water. Always keep your retainer in the case when you are not wearing it, pets, especially dogs, will eat it. Please be very careful with the care of your retainers, as they are an important aspect to orthodontic treatment. Like other personal items, retainers may also wear over time. Replacing a worn retainer is a wise investment in caring for your smile!
