Please tell me, could my orthodontic retainer work as a bite guard to protect against nighttime teeth grinding?

Most likely no: An orthodontic retainer is not designed to protect the occlusal surfaces from contact and trauma. I bruxism guard can actually serve both purposes. Speak to your orthodontist about options for your situation.

It's possible: If you had invisalign trays for your orthodontics, then you could use the tray as a brux guard, however there is not much thickness there and could be abraded very easily. If you have a traditional retainer without the surfaces of your teeth covered, then the answer is no. Ask your dentist if you have any questions.

Depends on the type: A traditional hawley retainer (acrylic and wires) normally will not work as a 'bite guard'. However, a full occlussal coverage bit guard (gelb) can work as a retainer. Speak to your orthodontist to get one that will work to protect against grinding and serve as a retentative appliance.

Not good: Retainers are designed to preserve new tooth positions. Night guards are designed to prevent grinding. Different functions, different designs.

Different functions: Retainers and night. Guards have different functions, ask your dentist or orthodontist if he or she can make some modifications to your existing retainers.To acumodat your brauxisem symptoms.

Ortho retainer: I just saw a patient with the same problem. He has retainers and he has used an nti for chronic grinding/clenching. I talked to his orthodontist who said he could make a comination appliance. Talk to your orthodontist about a combination appliance.

Of course: The full coverage bite guard will also help keep the top from moving. This is simply a night time retainer.
