We would never have to brush our teeth because they would never get dirty if we had a type of guard we could put over our teeth while eating. Since Invisalign exists this would definitely be a realistic invention that I’m surprised doesn’t already exist. It wouldn’t have to be tailored for each person’s teeth, just tight enough to stay on while eating. If this is a bad idea, why so?

You would probably still have to brush your teeth even with a way to fully cover and seal away your teeth while eating – the bacteria responsible for damaging your teeth and gums feed off the residual nutrients left in your mouth, not just stuck to your teeth.
If the cover isn’t full sealing away the teeth, then your nutrient ladend saliva will get into it, feeding those bacteria, causing issues in the long run.
In any case, the bacteria colonies living on your tongue will cause plaque buildup and bad breath even if you were abke to keep them off your teeth.
