My wife had number 37 (lower molar) removed after it split. Some weeks later
she bit down hard while eating and number 36 split as well. That also had to
be extracted (yesterday) as it had become infected. So now she has two
missing on the same side.

What would be next logical step? Is it possible/wise to do inserts for these
teeth (assuming everything else is ok). What are the risks involved with
inserts?

The fillings in those teeth wern't particularly large and the two teeth the
other side appear to be similar. Would it make any sense to do any
precautionary work on these or is that tempting fate?

Step One:

A complete survey and diagnosis about ALL of someone's teeth.

Then when there is an unexpected splitting, the patient is informed
beforehand! And the dentist is more-or-less on the line.

Yes inserts are a good idea.

The insert can be an IMPLANT after the bone thoroughly heals (3 mo- 6
mo) or it can be a fixed, non-removable bridge, or it can be a
removable partial denture.

The defining characteristics have to do with what is doing on the
other side of the mouth and what is doing with the patient's financial
ability and/or committment. False teeth can appear and function like
natural teeth.

Thanks for the reply  - it seems those numbers she gave me must be local
Belgian numbers or something. They don't match drawings on the web.
According to this diagram...
http://www.mistupid.com/health/teeth.htm
the numbers are...

18 - extracted a few months ago
19 - extracted yesterday

1, 16,17 and 32 were all extracted 20 years ago.  So she has three missing
now on one side 17,18&19.

I guess with 17 missing that would limit the bridge options?

> The defining characteristics have to do with what is doing on the

The dentist/consultant that extracted 18 and 19 suggested her regular
dentist might recommend capping 29,30,32 to prevent them going the same way.
These teeth have amalgum fillings in the center of the tooth but they don't
look really huge.

I think she's mainly worried about the other side failing in the same way.

An NTI device.

Arent they usually worn at night? Can they stop you chewing too hard while
eating?

You  cannot use enough force *while chewing* to damage teeth.  IF the teeth
are already damaged from years of night-time clenching, or if the enamel is
undermined from caries, then normal eating can be the tiny bit of pressure
required to chip pieces off.  But, chewing will not damage the teeth.

Amatus,

Although isn't it possible to wear teeth down if your bite is off?  My
husband has an underbite.  One of his top front teeth  (sorry I do not
know the number) is becoming significantly worn down due to chronic
(and inappropriate) contact with his lower teeth.

His dentist has suggested buildng this tooth up and re-setting his jaw.
(The whole break the jaw, realign, rewire etc.).  He relaly does not
want ot undergo this extensive procedure.

But my point is, chewing can wear teeth down prematurely when they are
not aligned properly.. correct? (or not)

Thanks,
Sue

If he is short on money his wife can do it for him.

Thanks. I think it must have been the caries. She actually felt one tooth
crack when eating. The dentist removed the filling and told her that it had
a vertical crack/split.

I hate to sound like a broken record, but vertical cracks, fractures,
splits, are not due to caries nor are they due to chewing.  Those are
created by parafunctional activity.

I was thinking more like parafunctional jeans designers ........

There is another set of nightguards for night-time chewing and daytime
clenching .......
