Previous articles have mentioned that after completing orthodontic treatment, there is an important stage where patients must wear retainers to prevent their teeth from shifting. There are several types of retainers, each with different usage methods and precautions. This article will help readers understand the different types of retainers, answer questions about retainers, and assist patients in properly wearing their retainers to ensure the success of their orthodontic treatment.
1. Fixed Retainers
After completing orthodontic treatment, the dentist will use a bonding agent or the same resin used for fillings to attach a metal wire to the back of the six front teeth. Patients cannot remove fixed retainers themselves.
The advantage is that patients don't need to remove the retainers to clean it daily, so they won't forget to wear it. However, since they can't remove it, cleaning the fixed retainer can be more difficult, allowing food debris and tartar to accumulate. Additionally, if the retainer becomes loose or damaged, the patient must see the dentist for immediate repair, or their teeth will shift. In the past, we've seen many patients come in with broken, dilapidated fixed retainers that required a new retainer to be made or even a repeat of the orthodontic treatment.
2. Hawley Retainers
The Hawley retainer is the most traditional type of retainers, composed of a metal wire frame and an acrylic base.
This retainer has a larger, thicker coverage area, so it is less comfortable and may take longer time to get used to. Patients also need to put it in themselves, and if they don't wear it as prescribed, their teeth can shift. Additionally, the metal wire is visible on the teeth, which is less aesthetically pleasing. However, Hawley retainers are more durable and can be used for a longer period.
3. Clear Retainers
Clear retainers have become the most popular type of retainers in recent years. They are made of clear plastic, similar to aligners, but slightly thicker, and patients can remove them themselves.
The advantages of clear retainers are that they are more aesthetic when worn and more comfortable. Since they can be removed, they are also easier to clean. However, patients need to have the self-discipline to wear them as directed. After completing orthodontic treatment, the recommended wear time is longer, and can later be reduced to just at night, as advised by the dentist. Dentists generally recommend replacing clear retainers every one to two years.
Consult your dentist immediately if your teeth shift
After knowing about the different types of retainers, you should have a deeper understanding of them. Whether you use a fixed or clear retainer, the most important thing is to follow your dentist's instructions for wearing it; otherwise, your teeth may shift, and all the previous work will be for naught. If you haven't worn your retainer for some time and feel pain or are unable to put it back in, you should immediately consult your dentist to see if you need a new retainer or need to undergo a second round of orthodontic treatment.There are also simple clear aligner treatments available for patients whose teeth have shifted without wearing a retainer, so it's best to consult your dentist early before the shift becomes severe.
