No - that's different, I know.
I am talking about nerve damage from the injection itself.
I read in several forums, that during wisdom tooth extraction or
during other dental procedures, the anaesthetic gets accidentally
injected fully into the nerve itself - when this is done, apparently
the patient feelings an enormous pain for a second & then nothing.
But once the procedure is finished after a few hours, everything's
numb because of damage to the nerve.

Is it possible during cavity filling? Anything the patient can do
to do to avoid it.

Yup.

Is it very painful - just replacing the filling - I am assuming drilling
doesn't have to be done again?
Are there any alternatives? After my wife's wisdom tooth
experience, I am really scared about dental procedures.

What are the effects of injury to the pulp?

I have hit the nerve directly many, many times when doing inferior
alveolar injections. While not pleasant (the patient generally feels
something like an electric shock along the distribution of the nerve out
to the lower lip, or to the tongue if the lingual nerve is hit), I have
never had a situation where the patient had numbness or even tingling
for more than a day or two afterwards. Of course, I've only been in
practice 30 years, so it could still happen, I suppose!
Seriously, there have been reported nerve damage after certain
injections with a particular anesthetic called articaine (Septacaine),
and while some dentists use this, I do not because of the reports I've
heard. You should be able to ask your dentist about this.

No. It's the dentist's job to avoid hurting the patient. You should
not have to worry about it.

You've had the tooth filled before--did you not get an anesthetic that
time? If decay or fracture of the filling is present, drilling will
have to be done of course--the majority of the drilling will probably be
to remove the old filling, but if there is decay or a need to reshape
the cavity the tooth may need to be altered by drilling as well. The
unknown is what if anything is going on with the nerve--perhaps nothing,
but if possible the cause of your pain should be determined.

In mild injury the nerve may be sensitive for a day or two; most of the
time an injured nerve will degenerate and you will need either a root
canal treatment or an extraction.

When you hit the nerve, you do not penetrate it. It's also very
difficult to make the needle stop just inside the nerve. So even if you
would try, it would be difficult to inject anesthesia directly into the
nerve.

That's the first time I hear about this. Any references?
We are advised to use articaine 4% with 1/200.000 or 1/100.000
adrenaline, due to higher chances of success (for mandibular
conductivity anesthesia: almost 90% with 1,8 ml). Mepivacaine and
prilocaine are much worse: even around 50% success for prilocaine.

I don't have any at hand, but it has been discussed here in the past
(check the archives). I've heard people claim they get mandibular molar
anesthesia with infiltration. Some have said here they avoid conduction
blocks because they're afraid.

I'm an old stick-in-the-mud--never incorporated Gow-Gates, Akinosi etc.
into my practice. But I'd say I get better than 50% success with
mepivacaine without vasoconstrictor with my mandibular blocks. I prefer
it for shorter procedures, obviously.

Don't you mean something like lido-hyal?

I used Akinosi once. Creepy ;-)

This is apparently (I don't speak German) some kind of preparation with
hyaluronidase. This seems to be an anesthetic. I'm not sure what the
enzyme is there for--perhaps to aid in perfusing the tissues.
I have no problems finding references for prolonged
anesthesia/paresthesia/ nerve damage after nerve conduction block with
articaine.

Update.
Finally got that tooth & 5-6 others filled in
2 sittings. Also had teeth cleaned in another
sitting. Everything was done without
any injected anaesthesia. No pain.
At the end of each filling session, the doc
sprayed some topical anaesthetic onto to
some thin plastic & asked me to hold it
between my teeth for 30 seconds.
Have some other questions, which I will ask
in a separate thread.
