Hello Everyone. I am a newby here and need some advice. I know
absolutely nothing about dentistry. What little I do know comes from
various Google searches.

I had 17 teeth extracted last Tuesday for new dentures. When the
extractions and alveoplasties were done, my dentist reached to his
table and picked up my new Valplast for the lower jaw and commented,
"Where's 19?"(he said this twice). I had no idea at that time what he
was talking about. He showed his assistant the Valplast and told me
he'd be back in a minute. Upon returning I noticed he had removed one
or two of the "teeth" on the Valplast. He then placed this in my mouth
and basically said I was done. The assistant gave me the information
that I needed to control the bleeding, etc. Being that my jaw was
completely numb and could not talk at all, I left it at that. The
receptionist handed me an appointment slip for this Tuesday. Several
hours later when I could feel my tongue, I noticed the slot for tooth
#19 in the Valplast.

The problem:

This Valplast has a hole for tooth #19 but there is no tooth #19. The
tooth or teeth he removed from the Valplast were #'s 26 and/or 27
which I still have. When he removed the tooth # 26 from the Valplast
I'm guessing the retainer that was supposed to wrap around tooth # 27
was also removed as I have only one retainer and that is on tooth #21.
There is a retainer around the hole on tooth #19. This is a temporary
partial which is to be replaced with the permanent in 6 months time.
It is very unstable with only the one retainer. What do I do? My
dentist is a man of very few words and didn't even tell me to come
back for any adjustments. I'd like to have a plan when I see him on
the 23rd. The charge on the temporary Valplast is $300.

The Upper Immediate Denture is OK.

One further question. Why do I have to wait 6 months for the permanent
lower partial?
