There are different types of retainers in the market. Mainly there are three types of retainers: removable wire retainers, removable plastic retainers, and bonded permanent retainers. Retainers are given to hold your teeth in the palace so that you can have a straight smile for life. 

Various factors contribute to the fact of how long your retainers would last. In particular, plastic retainers can last for 4-5 years if you take proper care of them. Understanding that your oral hygiene routine plays a key role in keeping your retainers up-to-date is vital. 

Plastic retainers are custom-made, just like your Invisalign. They are more delicate and require daily care to prevent them from damage. Apart from oral hygiene, the fitting of your retainers also determines how long they will last.

If you cannot floss your teeth properly due to the fitting of your retainers, it can reduce the span of your retainers to up to 2 years. Moreover, you can not wear one retainer for life no matter how much good care you take of them; it is necessary to replace them after 3-5 years.

Steps to follow to keep your retainers in good condition
