Retainers are essential for maintaining the alignment of your teeth after orthodontic treatment. However, they are not immune to wear and tear, and sometimes, the plastic part of the retainer can break. This can be a frustrating experience, but fear not! There are several ways to fix a broken retainer plastic, and in this article, we will explore various methods, from the most practical to the most creative.
Understanding the Problem
Before diving into solutions, it’s important to understand why the plastic part of your retainer might break. Common reasons include:
- Wear and Tear: Over time, the plastic can become brittle and crack.
- Improper Handling: Dropping the retainer or applying too much pressure can cause it to break.
- Chewing on Hard Objects: Biting down on hard foods or objects can damage the retainer.
- Temperature Changes: Extreme temperatures can cause the plastic to expand or contract, leading to cracks.
Practical Solutions
1. Using Dental Adhesive
One of the most straightforward methods to fix a broken retainer plastic is by using dental adhesive. This is a special type of glue designed for use in the mouth. Here’s how you can do it:
- Clean the Retainer: Thoroughly clean the broken pieces with soap and water to remove any debris or bacteria.
- Apply the Adhesive: Apply a small amount of dental adhesive to the broken edges.
- Press the Pieces Together: Carefully align the broken pieces and press them together firmly.
- Let it Dry: Allow the adhesive to dry completely before using the retainer again.
2. Using Super Glue
If you don’t have dental adhesive on hand, super glue can be a temporary solution. However, it’s important to note that super glue is not designed for use in the mouth and may not be as safe or effective as dental adhesive.
- Clean the Retainer: As with dental adhesive, clean the broken pieces thoroughly.
- Apply Super Glue: Apply a small amount of super glue to the broken edges.
- Press the Pieces Together: Align the pieces and press them together firmly.
- Let it Dry: Allow the glue to dry completely before using the retainer.
3. Using a Retainer Repair Kit
There are retainer repair kits available that include all the necessary materials to fix a broken retainer. These kits typically include a special adhesive, a moldable material, and instructions on how to use them.
- Follow the Instructions: Each kit may have slightly different instructions, so be sure to follow them carefully.
- Mold the Material: Use the moldable material to fill in any gaps or cracks in the retainer.
- Apply the Adhesive: Use the included adhesive to secure the pieces together.
- Let it Cure: Allow the adhesive and moldable material to cure completely before using the retainer.

Sugru is a moldable glue that can be used for a variety of DIY projects, including fixing a broken retainer. It’s safe for use in the mouth once it has cured.
- Clean the Retainer: Clean the broken pieces thoroughly.
- Mold the Sugru: Take a small amount of Sugru and mold it to fit the broken area.
- Press the Pieces Together: Align the pieces and press them together, using the Sugru to fill in any gaps.
- Let it Cure: Allow the Sugru to cure for 24 hours before using the retainer.
2. Using a 3D Printer
If you have access to a 3D printer, you can create a custom piece to replace the broken part of your retainer. This method requires some technical skill and access to the right materials.
- Scan the Retainer: Use a 3D scanner to create a digital model of your retainer.
- Design the Replacement Piece: Use 3D modeling software to design a replacement piece for the broken part.
- Print the Piece: Use a 3D printer to print the replacement piece using a safe, biocompatible material.
- Attach the Piece: Use dental adhesive or another safe adhesive to attach the new piece to the retainer.
3. Using a Heat Gun
If the break is minor, you may be able to use a heat gun to soften the plastic and mold it back into place. This method requires caution to avoid burning yourself or further damaging the retainer.
- Heat the Plastic: Use a heat gun to gently warm the broken area until the plastic becomes pliable.
- Mold the Plastic: Carefully mold the plastic back into its original shape.
- Let it Cool: Allow the plastic to cool and harden before using the retainer.
Preventive Measures
While fixing a broken retainer is possible, it’s always better to prevent the breakage in the first place. Here are some tips to help you keep your retainer in good condition:
- Handle with Care: Always handle your retainer gently and avoid dropping it.
- Store Properly: When not in use, store your retainer in its case to protect it from damage.
- Avoid Hard Foods: Try to avoid chewing on hard foods or objects that could damage your retainer.
- Regular Check-ups: Visit your orthodontist regularly to ensure your retainer is in good condition and to address any issues early.
