  Tooth  \Tooth\,  n.;  pl  {Teeth}.  [OE.  toth,tooth,  AS  t[=o][eth]; 
  akin  to  OFries  t[=o]th,  OS  &  D.  tand,  OHG.  zang,  zan,  G. 
  zahn,  Icel.  t["o]nn,  Sw  &  Dan.  tand,  Goth.  tumpus,  Lith. 
  dantis,  W.  dant,  L.  dens,  dentis,  Gr  'odoy`s,  'odo`ntos, 
  Skr.  danta;  probably  originally  the  p.  pr  of  the  verb  to 
  eat.  [root]239.  Cf  {Eat},  {Dandelion},  {Dent}  the  tooth  of  a 
  wheel,  {Dental},  {Dentist},  {Indent},  {Tine}  of  a  fork,

  1.  (Anat.)  One  of  the  hard,  bony  appendages  which  are  borne 
  on  the  jaws,  or  on  other  bones  in  the  walls  of  the  mouth 
  or  pharynx  of  most  vertebrates,  and  which  usually  aid  in 
  the  prehension  and  mastication  of  food. 
 
  Note:  The  hard  parts  of  teeth  are  principally  made  up  of 
  dentine,  or  ivory,  and  a  very  hard  substance  called 
  enamel.  These  are  variously  combined  in  different 
  animals.  Each  tooth  consist  of  three  parts  a  crown,  or 
  body,  projecting  above  the  gum,  one  or  more  fangs 
  imbedded  in  the  jaw,  and  the  neck,  or  intermediate 
  part  In  some  animals  one  or  more  of  the  teeth  are 
  modified  into  tusks  which  project  from  the  mouth,  as  in 
  both  sexes  of  the  elephant  and  of  the  walrus,  and  in 
  the  male  narwhal.  In  adult  man  there  are  thirty-two 
  teeth,  composed  largely  of  dentine,  but  the  crowns  are 
  covered  with  enamel,  and  the  fangs  with  a  layer  of  bone 
  called  cementum.  Of  the  eight  teeth  on  each  half  of 
  each  jaw,  the  two  in  front  are  incisors,  then  come  one 
  canine,  cuspid,  or  dog  tooth,  two  bicuspids,  or  false 
  molars,  and  three  molars,  or  grinding  teeth.  The  milk, 
  or  temporary,  teeth  are  only  twenty  in  number,  there 
  being  two  incisors,  one  canine,  and  two  molars  on  each 
  half  of  each  jaw.  The  last  molars,  or  wisdom  teeth, 
  usually  appear  long  after  the  others  and  occasionally 
  do  not  appear  above  the  jaw  at  all

  shape,  position,  or  office;  as  the  teeth,  or  cogs,  of  a
