Can retainers substitute for a night guard?

[alexx1202]

The enamel in my teeth has eroded away greatly thanks to lots of acidic drinks and bruxism (teeth grinding) at night. The dentist proposed a treatment plan which involves wearing an occlusal splint (night guard) to prevent further grinding. The splint costs around $500 which I really don’t want to pay especially if wearing my retainers can already solve the problem.

The bottom retainer has had some fragments chipped away but still fits (https://ibb.co/djv8j9x)

I also have a mouthguard from boxing so if retainers won’t work could I just use that instead of spending $ on a splint?

Thanks

Either would be fine - the retainer will wear out in time if you're a bruxer. Have you eliminated all acidic foods and drinks from your diet? e.g. soft drinks, sports drinks, citrus juices, vinegar, chewable Vit C tablets.
