Can you tell me some alternatives to dental anesthesia for asthmatics?

Not sure of your ?: Asthmatics can generally get local anesthesia. Are you referring to general anesthesia? Iv sedation? Since we can't possibly know your medical and dental history, nor examine you, you would have to discuss your concerns and ask specific questions to the dentist actually treating you as well as the physician treating you for your asthma. All this should be able to be worked out.

Procedure?: what procedure are you getting specifically? That would be important to know. For small procedures, personally I get them done with just local anesthesia. I also encourage most people to do the same.

Local anesthesia: In almost all cases, local anesthesia is safe for patients with asthma. If general anesthesia is recommended, propofol and ketamine inhibit bronchoconstriction. Never hesitate to ask your surgeon or anesthesiologist questions before the procedure.

Local injection: Local injection is the best. Local interligamentary injection can be used to isolately numbing a single tooth. Infiltration of the upper arch is easy. Lower arch teeth may require interligamentary injection to get it numb... Make sure have the asthma medication (spray) when you go to the dentist.
