Retainers for Teeth: What They Are, and Why They Matter

January 25, 2023

Orthodontic treatment, which includes braces or clear aligners, can straighten your teeth and improve your bite. However, the treatment does not end once the braces or aligners come off. Retainers are a crucial part of the post-treatment phase, helping to maintain the corrected position of the teeth. In this blog, we’ll dive into what retainers are, their importance, and how to care for them.

What are retainers? Retainers are custom-made devices made of plastic or metal that fit over the teeth to maintain their position. They are typically worn after braces or clear aligner treatment to prevent the teeth from shifting back to their original position. Retainers can be removable or fixed, depending on the patient’s needs and the recommendation of their orthodontist.

Why are retainers important? After completing orthodontic treatment, the teeth are not fully stabilized in their new position. Without a retainer, the teeth can gradually shift back to their original alignment. This is known as orthodontic relapse and can happen quickly, particularly in the first few months after treatment. The use of retainers is critical to ensure the teeth maintain their new position, reducing the risk of relapse and the need for further orthodontic treatment.

Types of retainers: There are several types of retainers available, including:

• Hawley retainers: This is the most common type of removable retainer. It is made of acrylic and a thin wire that fits around the teeth. It can be adjusted to maintain pressure on the teeth to prevent them from shifting.
• Clear retainers: These are transparent plastic trays that fit over the teeth. They are removable and offer a more aesthetic option for patients who don’t want visible wires or metal.
• Fixed retainers: These are thin wires that are bonded to the back of the teeth. They are not visible and offer a permanent solution for maintaining tooth alignment.

How to care for retainers: To ensure the retainers last as long as possible, it is essential to care for them properly. Here are some tips for caring for retainers:

1. Clean them regularly: Removable retainers should be cleaned daily with a soft toothbrush and mild soap or denture cleaner. Fixed retainers require regular brushing and flossing.
2. Handle them with care: Retainers can be delicate and easily damaged. Avoid bending or twisting them and store them in a protective case when not in use.
3. Avoid exposing them to heat: High temperatures can cause the retainers to warp or deform. Avoid leaving them in direct sunlight or hot water.
4. Keep them away from pets: Dogs and cats can be attracted to the smell of retainers and may chew or swallow them, causing damage to the appliance and harm to the pet.

Retainers are a crucial part of orthodontic treatment, helping to maintain the corrected position of the teeth. There are several types of retainers available, and their care is essential to ensure they last as long as possible. By following the tips provided and attending regular check-ups with your orthodontist, you can ensure your teeth remain in their new position for years to come.
