Sometimes..when there is absces in the tooth that need treatment..the injection didn't work because of the pH..the absces is acidic while the local anaesthesia is alkaline..so they neutralized each other..Variation in anatomy i.e location of the nerve is slightly out of its usual course also a possible caused...i've suffer similiar problem where i try to numb this particular patient on the first shot but failed..only after the second shot she's totally numb..Lastly..no offense..the psycholigical..the teeth are actually numbed but ur brain still think it has not been numbed..
But i think 7x is kinda too much for a patient to handle.

I'm a dentist.
Good God Allmighty!! The answers I'm seeing here are so utterly clueless.
Cocaine use causing resistance? I cannot believe a dentist said that.
Drinking causing resistance to the anesthetic?
Let me address these two points.
Cocaine is an ester that is metabolized in the blood. Lidocaine is an amide that is metabolized in the liver. Metabolism of the two are apparently unrelated. You become "resistant" (i.e. addicted) to cocaine because of its effects on your nervous system, not because your body is better able to metabolize it causing you to require more of it. Additionally, Lidocaine (when used as an anesthetic and NOT as a cardiac anti-arhythmic) works directly on the nerve that you're trying to numb. It binds to the membrane channels at the Nodes of Ranvier and blocks the influx of sodium into nerve's axon, thus preventing action potentials and thus nerve function.
Someone who was a heavy drinker, but with no liver damage, would likely have more liver enzymes capable of metabolizing the lidocaine and would thus be able to metabolize lidocaine more quickly and thus handle higher doses of lidocaine without suffering the effects of lidocaine toxicity, but they'd still get numb because their nerves are just as susceptible to the effects of the anesthetic. Heavy drinkers, in reality, should be given limited doses of lidocaine because they may have liver damage that would make them less able to metabolize the drug.
Anyways, to answer the original question:
It can happen from time to time that we cannot get a tooth numb. There can be variations in anatomy, such as additional nerves providing sensation to the tooth, or perhaps the inferior alveolar nerve your doctor was trying to block was in a different position than the nerve is found in most patients.

One can argue the dentist made a mistake, but come on 7 times in a row? highly unlikely. If you are a heavy drinker, or drug user, you will build a resistance to the anesthetic. It also might be in your head, if you're someone who is afraid of the dentist in general.

I don't know, she may not have been injecting where she was supposed to. The same exact thing happened to me. Only on the 7th time he did it, it did go numb. It stayed numb, too, for 6 hours later.

She might not have given you enough the first time! The same thing happend to me! My Dentist numbed my gum about 4 times once! I had to have my last baby tooth pulled and every time he started to pull..................my gum around the tooth would start to hurt. After he numbed it for the last time, he waited for 30 minutes. It was really numb that time!

next time try letting her hit you in the head with a ball bat that will make you forget about not having a numb mouth.

an occasional problem occurs in which the nerve is not easily affected by the anesthetic. usually the dentist has no problem, but in a few cases he/she may not hit the nerve just right to get it numb. also, you may not be as suseptible to the medication she used.

That happens to me as well. It's a matter - according to my dentist and I don't know if he's guessing here - of a resitance to the drug.

I had the same prob. The dentist said it was because of excessive cocaine use in my past, although I'm clean now. Not sure if that helps.
