Question
I am going to the dentist in 2 days.  I am having 2 root canals.  One is under a crown which will also be removed.  I have another molar next to that one that is broken and both have some decay.  I was offered Valium or Nitous Oxide (not sure of spelling) because of my high anxiety.  Can you tell me if either is a good thing for me or are there negative side effects?
Thanks so much!

Answer
Wendy,

Congratulations for making the commitment to have your teeth fixed.  Nitrous oxide is a gas that is breathed through the nose during the procedure.  Most people remain completely aware of what is going on, but it makes them not care quite so much.  It is best for mild-moderate anxiety.  You, the patient remain completely in control because you can simply breath through your mouth at any time to make the effects go away.  Nitrous oxide is very safe and has no long term consequences when administered properly.

Valium can be given in several forms.  It is most often administered either as a pill by mouth before the procedure, or through a needle in the arm (intravenous sedation).  At low doses, valium is very safe for most people.  It should not be used for people with Narrow Angle Glaucoma, compromised kidney or liver function, or who are pregnancy or nursing.  The effects of Valium are prolonged, so hazardous tasks should be avoided for the remainder of the day.  It is best to avoid alcohol containing products/ beverages.  Other sedative and psyco-active drugs can have cumulative effects.  Valium should be avoided if there has been any prior addiction tendency.

Valium is safest when delivered intravenously by trained personnel.  Oral doses are fairly safe as long as only low doses are used.  In either case, a caregiver should be available to drive the patient home following the procedure and care for them for a little while.

Hope this helps.  Best wishes.
