Once you finish your Invisalign treatment, your dentist will give you the retainers. Retainers are used to keep your teeth in the perfect position after you are done with your Invisalign treatment. It is vital to wear a retainer because the teeth tend to move back to their original position, and retainers will help you prevent that. Your dentist will give you custom-made retainers to avoid any dental relapse. There are two types of retainers: metal retainer, and the other is plastic retainer. Both the retainers work similarly and prevent your teeth from shifting. It depends on you and your dentist which retainer you must wear after the Invisalign treatment. Both the retainers provide almost equal effectiveness in improving your teeth straightening process.

Both metal and plastic retainers are made using the patient’s teeth impression. Plastic retainers are made of clear plastic and are easily removable, whereas metal retainers consist of metal and acrylic parts that come in a permanent and removable form. In addition, it depends on your teeth condition for how long you have to wear retainers, and your dentist can guide you about that. In different cases, you can be told you wear your aligners at night only while sleeping or during the day several times a week.
