Crown over live tooth, is it safe?

[amedinaok]

The new dentist I visited took out an old silver filling by drilling it instead of suctioning it, in spite that I had specifically requested suction. He filed my tooth and is planning on putting a crown over it with no root canal.
Does anyone knows if that is safe? Wouldn't the tooth be too sensitive afterwards? I'll appreciate your imput on this issue. Thanks.

What your dentist did is safe, and proper. It's impossible to just suction out an old silver filling, it must be drilled out.

You don't always need a root canal filling.  It depends on the damage and how far the decay has got to.

Having a crown over the top of a restoration will be fine.  
The dentist is the one that is qualified and an expert in his field.
I didn't even know that an old filling can be suctioned out.  I can't see how it can be suctioned out if it is bonded to your enamel.

There may be some sensitivity for a while until things settle down and you may experience a high bite with a new crown.

If there are problems afterwards, you would need to go back to your dentist to check the bite.
