There are multiple reasons for shortness of breath after Dental Surgery.  Pre-existing lung issues, asthma, COPD, smoking, marijauna use  are some.  Others related to anesthesia include mild inhalation of saliva or bleeding from the surgical site, residual action of muscle relaxants (neuromuscular blocking drugs) used during surgery, genetic variations changing drug metabolism.  Is there a family history of problems with anesthesia?  Plasma cholinesterase deficiency is a possibility if succinylcholine was used.
The best source of information is the anesthesiologist who gave you the anesthetic.  Give them a call and arrange a follow-up appointment to review your anesthesia record.

Can anesthesia cause an irregular heartbeat?

Modern General anesthetic drugs are unlikely by themselves to cause a serious irregular heartbeat in a young healthy individual, taking no medications and not using street drugs.  READ MORE
Modern General anesthetic drugs are unlikely by themselves to cause a serious irregular heartbeat in a young healthy individual, taking no medications and not using street drugs.  Irregular heartbeats can be caused by surgical stimulus, or other drugs used by the anesthesiologist or surgeon.  Anesthesiologists are well trained to respond to serious heartbeats when they do occur.  Everybody has some insignificant heartbeat irregularity on a daily basis.

If you are a healthy 34 year old male with normal back and normal spinal cord, the risk of paralysis is extremely rare.  Your chance of paralysis from being in a motor vehicle accident is greater.
I have had 3 spinal anesthetics for knee surgery, to avoid having a general anesthetic, so you see where my personal bias lays.

Can a spinal epidural cause back pain?

Back pain is possible after c-section, but it is difficult to know whether it was caused by the changes in your back due to pregnancy, lying on a hard operation room table or by READ MORE
Back pain is possible after c-section, but it is difficult to know whether it was caused by the changes in your back due to pregnancy, lying on a hard operation room table or by the spinal or epidural anesthesia.  (Usually an elective c-section is done with a spinal not an epidural).  Your anesthesiologist will discuss the risks and benefits of the various options prior to your surgery.
For women who go into labor, the incidence of back pain is similar in patients with no epidural and with an epidural.

This website has a reasonable discussion of lidocaine.  The type and probability of a side effect or complication depends on the location and quantity of the drug that is injected.  Some of the side effects noted are usually caused by extreme anxiety at the time of, just before or after the injection causing a patient to faint (vasovagal reaction)!

Do you feel pain during anesthesia awareness?

I really don't have any statistics on this issue.   There are 3 components to a general anesthetic: analgesia (pain control), amnesia (can't remember what happened) and loss of consciousness.  Different medications used during surgery and anesthesia contribute to 1 or more of these components by acting on different drugs receptors in the body.  Awareness occurs when there is insufficient medications to cause amnesia and loss of consciousness.   
If the anesthesiologist or surgeon administers a sufficient amount of pain medicine or local anesthetics in the area of surgery to block all the pain, one should not have any pain on the rare chance there is awareness during a general anesthetic.

How long does local anesthesia last?

Why do they tape your eyes shut during surgery?
