When should an SCMS blade be discarded?

[strangerep]

In a recent accident, one tooth of the aluminium cutting blade on my
SCMS got bent slightly sideways. I hammered it gently back into alignment
but I was surprised how easily the bent tooth went back into position.
So now I'm wondering whether this means there's a lurking stress fracture
in there that's waiting to injure me if I try and use the blade again.

Should I risk using the blade again, or just toss it and buy a new one?

If it's usable, then there's another problem: while hammering I accidentally
knocked off some of the carbide coating of a neighboring tooth.
Can teeth be recoated if I take it to a sharpening specialist, or is just
better to buy a new blade?

It definitely needs professional help.

They can fit new teeth or advise if it is not worth it.

If I damage or bend a tooth, I put another blade on and mark the damaged section with a marker and take it to the saw blade man.

Thanks for the rapid reply! I'll do as you suggest.
