Default Camshaft seńsor teeth ground off. Tear Down?

My engine was rebuilt a few years ago. The oil pressure dropped to 0. Turns out the camshaft position sensor teeth were ground off. About 3 of them. I took it out and am getting a new one. Would the ground teeth just drop into the oil pan or can that metal get into the engine. I am trying to figure out if I can just drop in a new sensor or do I need to break down the engine to get metal out. If so how far down do I need to go? Take off the valve covers? The heads? I am not sure where the metal could go. When I look down in there I can see the cam shaft gear which looks fine but I cannot see the whole gear. Do I need to take the camshaft out? I am taking the engine out taking off oil pan to see what is in there and if there is metal in the oil pump.

I believe those teeth are composite. Not the best thing to get in your oil, but I'd be more worried about what happened to your bearings when the oil pressure dropped.

Yes I am in process of removing the engine. Once I get the valve covers off do I need to take off the heads to get to camshaft and bearings? Can I take out the camshaft and camshaft bearings to inspect and then just put right back in or does a machine shop need to put the old or new bearings and camshaft back in? Same on bottom. When I take off the oil pan and look at bearings can I just put them back in or is it more complicated. Thanks!

You can inspect the crank and rod bearings yourself. Plastigage will be required for getting the measurements. For the cam bearing you'd need the required tools to remove and replace. If the engine appears to be intact, I'd pay a machine shop to clean the block up and check over all the measurements. They can tell you what needs to be machined, help you order the right sized parts, etc.
