Retainer Use After a Long Break

It's very common for people to just suddenly stop wearing retainers; their lives get busy, and a retainer seems less essential once the teeth have been straightened. But too long off can set the teeth back into their previous positions. If you haven't worn a retainer in years, you should familiarize yourself with the risks and consequences you might face. You may experience discomfort or find that it no longer fits properly. This is a common issue, especially if your teeth shift after not wearing a retainer. Understanding the cause of the pain and knowing when to seek professional help can prevent further dental problems.

Can I Wear My Retainer after Not Wearing It for Months?

Is it bad to put your retainer in after a long time? It is a question many people ask.. The answer lies in how long it has been unused. If it has been a short time, a retainer can still be used, thus helping in preventing any further movement. If it were months, putting it in could not help your teeth maintain results or cause other dental problems. However, it is advised to visit your orthodontist before using your retainers again in such cases.
