My tooth did not get numb at a previous visit: what should I tell a new dentist?
Tell the new dentist exactly what happened: which tooth, upper or lower, what procedure, whether the tooth was painful or infected at the time, how long you waited, whether more anesthetic was given, and whether you felt lip or tongue numbness but still felt the tooth. One failed numbing usually points to a reason that can be planned around, not to a patient who "cannot be numbed".
Common reasons
- Inflamed or infected teeth are harder to numb than calm ones; acid in inflamed tissue reduces the anesthetic's effect
- Lower back teeth rely on a nerve block that can miss by a few millimeters
- Anatomy varies: extra nerve branches, dense bone
- Too little waiting time before starting
- Anxiety and fatigue lower the pain threshold
- Rarely, a true difficulty with a class of anesthetic
The American Dental Association describes local anesthesia and the options dentists have (ADA).
What the dentist can plan
| Situation | Approach often used |
|---|---|
| Infected tooth | Settle the infection first where possible; supplemental techniques |
| Lower molar block missed | Supplemental injections around the tooth or into the ligament; a different block |
| Short waiting time | Longer wait; test before starting |
| Anxiety | Comfort options; explanation; stop signal; the studio lists longer appointments, nitrous oxide and anti-anxiety medication after a health history (studio) |
| Repeated difficulty | Different anesthetic type or technique; referral if needed |
What to record
Date, tooth, procedure, whether it hurt before the visit, what you felt during, what the dentist did, and how the visit ended. Bring it to the new office.
During the next visit
Agree a stop signal; ask the dentist to test the tooth before starting; say at once if something is sharp. More anesthetic or a different technique is standard.
This page gives no doses and names no anesthetics.
Next step: Request a consultation or call (805) 565-5111. A request is not a confirmed appointment; the office confirms times during its listed hours (Monday to Thursday, 8 am to 5 pm, plus select Fridays).
Past anesthesia experience record
| Item | My answer |
|---|---|

Questions for the new dentist: what likely happened; what you will do differently; test before starting; stop signal.
