I just came back from a checkup at my dentist; same dentist last few years. She seems on the ball but lacking that last bit of ability...

Anyway. Two years ago, I went to her for a filling and no amount of anaesthetic would work; I ended up having three injections and waiting for half an hour; I could still feel the work being done. She said she'd never had that before. So, fast forward to present day - I apparently need a filling replaced. I said straight away, I'm not sure I'll be going through with it - and then reminded her of the saga, last time.

She then talked about sedation and the like. I said, I've never had a problem with anaesthetic working before - and I don't like the idea of sedation.

Has anyone here ever been given enough anaesthetic to numb a dinosaur limb; but it not work? And, should I be going to a different dentist? Could it have been her technique in delivering the injections?

No idea but I found conscious sedation to be very restful though does seem a bit much for a filling.

Was it an upper or lower tooth?

Sometimes lowers can be bit tricky to numb, the anatomy can be a bit variable.
Uppers are usually easier.

Sedation can be helpful if you're a bit anxious, lowers the pulse rate and gives the local anaesthetic a bit more of a chance to work. Other techniques for administering the local can help too.

Yes.

I needed a root canal last year that I ended up putting up with for nearly 10 months as the anestitic didn't work. Dentist who is usually fantastic tried all sort of stuff, techniques and different spots. Nothing worked and in the end I had to just squeeze the chair whilst he drilled through and relieved the pressure of the gas building up underneath the tooth.

It can happen, I can't remember the science but I believe it was to do with the shape of the tooth and position of the "angry" nerve.

I've had plenty of work done before by him with no problems and will be returning when nessacary.

Yes. Genetic condition that makes local anaesthetic not work very well here. Are you unusually bendy and/or have joint issues?

I've had fillings before and the anaesthetic has worked - and so this was a lone incident and made me think that the dentist was not up to the job - or she used the cheap stuff (do different brands of anaesthetic even exist?)

I have the opposite 'problem'. If I have muscle pain I take half an ibuprofen and it knocks me out for a day. It's like thinking through treacle.

I had a biopsy with a full anaesthetic and my heart stopped beating for 7 minutes. This is, I am reliably informed, bad for you.

I had a chat with my doctor about it and he reckoned that only abut 40% of people find any effect from paracetamol - half a pill for me - and about half find ibuprofen any use, that's once the placebo effect is taken into account.

It would appear that there is a whole range of effects from all types of painkillers and at the time, some 20 years ago, I was told that no one knows why.

There are lots of different generic brands but they are all manufactured to the approved formulation laid out by the various regulatory agencies so there shouldn't be any massive differences in performance, providing they are used correctly, have been stored correctly and are in date.

I had a root canal that took a lot longer than anticipated and the dentist was trying to get the tooth closed before giving me a top up of lidocaine. He didn't want to risk removing the surgical dam and getting contamination in the root canal. Needless to say, having hot latex poured into an open tooth with partial sensation was not pleasant, I nearly tore the arm off his chair......

The silver lining being that he didn't charge me for the procedure.

I'd be tempted to go for the filling with the proviso that if you have any sensation after the lidocaine the procedure is stopped or sedation is offered before continuing.

Erm, yes.

I had some root canal work done where the local anaesthetic hadn't worked as well as I'd have hoped, however the worst was when I had an apicectomy (sp?) and the anaesthetic just didn't seem to be effective; that smarted a bit.

I've experienced similar and ended up with 5 injections before the pain was reduced. Snag is, I got facial palsy for a few hours afterwards - couldn't blink so they taped my eyelid shut to avoid the eye getting dry.

I'm pretty sure when I had a triple root canal treatment done a couple of years ago I ended up with nine injections and about a 90 minute wait before they could crack on.

I say pretty sure because after the first half a dozen injections the rest became a bit of a blur.

I've had teeth like that. Unexplained as I'm usually pretty accurate with local. A mate is impossible to numb. We had to cancel drilling as wasnt working..then on his way home he phoned to inform me it now was numb..returned and sorted..bizzarre.

You may want to think about not bothering with being numbed up - I'm not a fan of needles & don't take an injection, except on the rare occasions when I've had to have a tooth out. Only this week I had an old filling replaced & I honestly didn't feel a thing.

I've had the injection fail once; she started drilling, I nearly jumped out of the chair. Got another shot, waited another twenty minutes...same thing.

She'd numbed the wrong nerve apparently; I was told that I had several in the roof of my mouth and she'd got the one that numbed everything else. With the dose I'd got from the two shots, I was numb for about 8 hours, not much fun.

Back again a week later, no drama.

My current dentist uses a metered system that bings and bongs at you and works in about 5 minutes flat. Excellent stuff, except when it bongs for what seems like 15 minutes, they stop, change the cartridge to give you some more....you know you're in for it then.

Some people are more susceptible to it than others. I'm like you, unless it's the kind of dosage that will knock out a dinosaur then it has no effect on me. I went through this myself about 5 years ago when I needed some root work doing (on the NHS). What I didn't realise at the time is the dentist is up against the clock to do the work because they only get paid buttons from the NHS so they need people in and out ASAP. I got in the chair and he fired in a couple of jabs of anesthetic and 2 mins later started digging around in the cavity. Unsurprisingly I hit the roof and strong words were exchanged before he tried again and the same thing happened. I was that angry over it and no longer trusting of his abilities that I walked out in disgust.

Unfortunately that didn't solve my broken tooth issue but I was extremely lucky to find another NHS dentist with a free space from a recommendation. This was a woman dentist and I told her of the experience I'd just been through. She said it wasn't a problem and I should come in 30 mins before my appointment time and she would quickly give my the injections so that the anesthetic had time to take effect. Sure enough, worked like a charm and when I went in at my appointment time I couldn't feel a thing. Ultimately the tooth had to come out as there was some complications so she did the same thing on my next visit and I was sat there perfectly calmly as my tooth got chopped into pieces in order to get it all out.
