recent dental cliric in New York city
showed d number of wonderful new ad-
vances in dentistry, but most of all it
proved how little the average man knows
about the work done to his teeth.
For instance. how many patients are
aware that half the hard cement Filings,
known as porcelain cen,ents or arliii-
cial enamcls, are spoiled BY heating when
the dentis. trims theri into shape with
his little whirling disk? If the dentist
ereases his disk with cocoa butter o.
sonie other lubricant no heating and no
harm results. Heat causes the fillins TO
expand i'll the cavity and later. in con-
tracing. to pull away from the tooth
and leave space Cor saliva and decay TO
enter.
As every one knows, either chloroform,
laughing gas and other narcotics vii,

as ''analgesia." Analgesia is way sta
ton on the road to Alae sthesia, where
the patient is conscious, can hear, see
and talk, Tut cannot feel pain. At the
clinic were two new devices for producing
analgesia
Both work by Insans of a li.tie mask
which fits over the nose, but leaves the
mouth free for the dentists work, and
for tile patient to breathe air whenever

While the other causes analgesia through

IL, the patient rds himself of the last
fumes of the analgesia and steps out of
the chair feeling just as he did when he
got in. There is no di2znes or nausea
This is real. painless dentistry, and any
