Mouthguards from the dentist as good as orthodontist?

I would think so: As long as they are custom lab made on models of your teeth.

Yes. : No reason a general dentist cannot make a night guard as good if not better than an orthodontist. I would think a majority are made by general dentists.

Yes: Usually a custom made mouthguard from a dentist or an orthodontist is just as good. The otc store bought or internet purchased mouthguards are inadequate, including the boil and bite, etc. Mouthguards vary based on the purpose, person's age and the dentition. Don't skimp for a cheap one otherwise it can cost you a lot more than fees in the future. (moving teeth, tmj/tmd, pain, change in bite..

Mouthguard: Yes. As long as both are "competent".

Yes: A mouth guard is there to simply protect your mouth. There are many types and ways they are made, but you can get them from either and it will be more than fine.

What kind?: I think, as an Orthodontist, that General Dentists do a slightly better job fabricating Athletic Mouth Guards. I think Orthodontic Specialists do a better job with Orthodontic Retainers. I think thy both do equally well fitting and adjusting an Occlusal Orthotic for TMJ pain relief. But know that the difference is statistically extremely small.
