How many anaesthetic injections would someone require to have a molar root canal!

Best Answer - Chosen by Voters

$220 for a molar root canal is a screaming good deal. In some areas they are charging about six times that.

It's not so much the number of injections ("sticks") but the quantity and type of anesthetic used. Local anesthetic can be toxic. Each type has a recommended maximum dose, however the toxic levels of different types of anesthetic are not additive. In other words, if your dentist administered the maximum safe dose of lidocaine and you were still experiencing discomfort, he/she could switch to carbocaine or another local anesthetic and then give you the maximum safe dose of that anesthetic.

You should not be in pain during the procedure. There are various adjuncts for administration of local anesthetics - different types of nerve blocks, intraosseous injections, periodontal ligament injections, specialized syringes, etc., but when a tooth is "hot" it can be a challenge to achieve satisfactory anesthesia. More than one method of administering local anesthetic may be used during an appointment to achieve patient comfort.

Personal experience. I'm a dentist.

I've starred my friend will answer, she's a DSA.

The number of injections required depends on the individual. I can't imagine why they would not give you a third injection, if you were still feeling pain. That seems to me to be uncaring or lazy, as if they were on a schedule, and it would put them behind if they had to wait another 5 minutes for the third injection to take effect.

When I had a root canal, my dentist started with two injections, left the room for a few minutes, and when he came back, he asked if I was completely numb. When I hesitated, he joked, "That's fine, I have lots more anesthetic if you need it." :-) I only needed one more shot, but I could have had more than that, if necessary. I don't think you were anywhere close to the safe limit.

In any event, the point is that a good dentist makes every effort to keep his patients pain-free. That is how the dental school should be training its students. I think you should bring this issue up before you have the next root canal. You may be like me, someone who needs more than the average amount of pain killer. They need to adjust their timetable to take that into account.

Good luck, and I hope this is helpful.

I was at the dental hospital once i needed a tooth pulling out i had 2 injections and then a student tryed pulling the tooth out he was trying for 5 mins and couldnt do it, then all of a sudden a proper dentist walked in the room and said il do it and the tooth came out straight away, but i suppose the students have to learn somehow but personally i would of rather he didnt as it was very painfull. it should be 1 injection if not 2 to make sure the area is numb

OK, first of all you don't state if it's an upper or lower molar you are having treated. Totally different injections, Upper is a infiltration and the lower is an ID block (which can be difficult and do take longer to work sometimes). Secondly, it shouldn't take 3, 4 or 5 attempts to get the area anaesthetised. If you're needing a root filling, it could be you've got and infection there at the root. In which case the local anaesthetic won't work properly and you'll need a course of antibiotics to clear it. Never in all my years as a dental nurse have I seen more than 3 cartridges of anaesthetic used to numb one tooth, and I've never seen one of my dentists attempt to carry out treatment unless the area was completely numb.

You really need to be asking whoever is supervising the student this question. I can't give a clearer answer without more information.

Ok upper or lower jaw?

It's not the amount of TIMES they inject you it's the AMOUNT of anaesthetic they use. They can inject many many times using the SAME cartridge, administering small amounts at a time. That's why you need to ask whoever is there supervising why the anaesthetic isn't working. Nobody else can give you an accurate answer without knowing what sort of anaesthetic and how much they are using, how and where they are injecting. Every patient is different.
