The present invention relates to a novel teeth

reach the areas of the gums which require stim

In the cutting of teeth by’ an infant there is
normally little dii?culty with the cutting of the
ances may be of any shape or design effective for
' the purpose, although it is to be understood that
the device may be made smooth, if desired.
Further objects are to provide a construction
of maximum simplicity, emciency, economy and

six lower teeth. These are the ?rst to arrive objects, advantages and capabilities as will later

However, in
the cutting or eruption of the posterior teeth or
molars, since these are Y formed with a broad
erupting surface having spaced cusps, they most
generally cause considerable pain and soreness
in the gums ‘and require stimulation and aid in
their eruption.
The present invention has for an object to aid

Another distinct advantage of the present in
vention is that when thedevice is inserted in the
mouth of the infant, there is nothing that inter-_
,feres with the tongue or which would be of a
sufiicient length to touch the soft palate. Thus
it will be noted that no portion of the device will
overlie the tongue su?icient to interfere with i
or cause gagging or choking. ‘
- " further object of the invention is to provld
a teething device with suitable raised portions in
the form of ridges, corrugations or protuberance-s
these'projections preferably increase in thickness
and width from the central portion 4 to substan-- 45
tially the point 5 which is adjacent the outer
ends. The shape of these projections is such that
a vertical cross sectional viewtherethrough would _ -
be substantially elliptical, the purpose of which
is to provide a maximum contact area for engage- '50 V '
ment with the gums. while the shape of the en- ‘
tire‘ device lends itself to the contour of the
dental arches and permits the central portion 4
thereof to be placed or located intermediate the
anterior teeth which have already erupted. The 55 L I
