My Dog Chewed My Retainer: What Should I Do?

If your dog chewed your retainer, stop wearing the damaged appliance and contact your orthodontist promptly about a replacement. If your dog may have swallowed any of it, contact your veterinarian too. A replacement retainer and a possible swallowed object need separate attention.

Start with two calls, not a DIY repair

The American Association of Orthodontists recommends notifying your orthodontist when a dog damages a retainer. Ask what to do about your wear routine while a replacement is arranged. Retainers help maintain tooth position after treatment; a damaged one is not something to keep using while you wait. See the AAO's guidance on dogs and retainers.

If pieces are missing or you think your dog swallowed plastic, call your veterinarian for advice. Explain what the object was and when it happened. Swallowed objects can cause an intestinal obstruction, which requires prompt veterinary care; do not assume a piece will pass harmlessly. Cornell's veterinary guide explains the risks.

What to tell your orthodontist

A short, specific message makes the next step easier. For example: “My dog chewed my upper clear retainer this morning. It has a split near the back. My lower retainer is undamaged. What should I wear, and how can I arrange a replacement?”

• Which appliance: upper, lower, or both.
• What happened: chewing, missing pieces, or a case that was damaged with the retainer inside.
• When you last wore it: give the actual day rather than guessing how long you can safely wait.
• What you have available: mention any spare set and ask whether it is appropriate to use.

A photo can help explain visible damage. Keep recovered pieces away from pets while you seek advice. Do not glue, heat, or bend the retainer back into shape as a home repair. For other damage scenarios, see why retainers crack or break.

Choosing a replacement

Start with your orthodontist's guidance, especially if your teeth feel different or you are unsure about fit. Replacing a retainer is about maintaining position, not moving teeth back into alignment.

If an at-home replacement is suitable for you, Mavira's process starts with an impression kit. You take impressions at home, return them using the prepaid shipping materials, and the lab makes your custom retainers. Review the Mavira retainer kit and set options before ordering. Tell the team what you need to replace rather than assuming a damaged appliance can be copied or repaired.

Make the storage spot harder to reach

Put your retainers in their case whenever you remove them, then store the closed case in a closed drawer or cabinet your pet cannot access. A bedside table or an open bag can still put the case within reach. Do not leave retainers wrapped in a tissue or napkin.

Make the habit practical: choose one storage spot you can use every day, including during meals. If the case was chewed too, replace it rather than relying on a damaged lid. Our retainer case guide covers choosing and caring for that everyday storage essential.
