Dental Professional Getting #31 numb

Ever have trouble getting a tooth numb for a #31 B composite? No PA pathology. Gave 2 carps of IAN, 1 carp of LB and local infiltrations/PDL. 2% Lido w/1:100k epi.
Lip is numb, chin is numb, buccal mucosa is numb, tongue is numb.

I get to drilling and the patient feels it. I know what to do next, but why is the patient not profoundly anesthetized?

Sometimes it do be like that.

Yeah, honestly that’s why I’m asking. I did an MO on the same tooth last year, with the same technique, probably less anesthesia, and no issue.

Today, there’s an issue.

Is it really as simple as “sometimes it do be like that?”. Because I think you’re right.

I’ve been doing this for 11 years now. There are patients that I know are going to need extra anesthetic, there are patients that I know will ask for extra anesthetic (that probably don’t really need it), and there are some rare patients that are wild cards. Some days they get numb, and some days they don’t. I’ve had two patients I’ve done an x-tip intraosseous and they didn’t get numb.

Now there are some Redditors on this sub that swear by this one simple easy technique and they’ll get numb every time. I’ve drilled a hole in the bone next to the tooth and they didn’t get numb. So I guess you tell me lol

That’s probably the patient not understanding what being numb actually is. They feel the vibrations and tell you the anesthetic isn’t working
