Alternative pain relief to injections during dental work?

Does anyone know of anywhere (I'll pay if I have to) where I can get an alternative such as gas to dental injections? I have a serious needle phobia and am completely unable to let anyone inject in my mouth. Up to now I have been lucky and have no fillings (i'm 26) but have had to have treatment for gingivitis without injection which is agony. The dentist originally refused to do it and couldn't believe I went through with it, but frankly I'd take a whole load of pain to invoid an injection. My concern is that if I need root canal work or deeper gingivitis treatment I won't be able to cope... Will anyone give me gas in the UK?

you should ask your dentist about sedation rather than gas. You aren't knocked out you are still conscious but really relaxed and it also causes amnesia so you wont remember getting the treatment afterwards. You'll still need to have injections either way and root treatment would be extremely painfull without them as you are removing the nerve from the tooth. Personally I would rather get the injections as they aren't that bad, you could ask your dentist to put on a anaesthetic gel before the injections and you hardly feel them.

Reply:Just wanted to say, I am completely needle-phobic too and had to have a root canal filing last year (Harley St). I was given an anaesthetic injection but they put this gel/spray on my gum before so I actually didn't feel the injection at all. I also had my eyes closed the whole time so didn't see any horrible needle! So, if you can't find anywhere then ask if you can have this gel/spray thing put on first as it really really makes the whole thing bearable! Good luck!

Reply:In kids some dentists use gas, which is actually protossido of nitrogen. But in my opinion it is always better the injecton.Try to understand if it is about seeing the needle or the small pain you feel while they do that.In the first case it is all about working on yourself.In the second case you should understand that is just a second.Anyway dentists use a lidocaine spray (if you ask for it)on the gum before the injection,so you won't feel anything.
