DECA-i 
Strange as it may seem, 
the cause of decay of the 
teeth was unknown till a 
few years ago. It is nothing 
more or less than lactic acid. 
Where does it come from ? 
Is there a way to avoid it? GERMS 
They are in the mouth, 
and alwayswill be ; we can’t 
do anything with them. 
They are probably useful in 
some way unknown ; it may 
never be known. 
They do this mischief, 
however. Their food or soil 
(whichever we ought to call 
it) is sugar and starch. They 
turn both sugar and starch 
into lactic acid; and lactic acid eats the lime of which 
teeth are made. 
And this is decay. 
HOW 
Sugar and starch get be- 
tween the teeth, into cracks 
crevices nooks and corners, 
and stay there. 
The germs are always 
ready. Lactic acid is formed 
whenever the starch and 
sugar stay there long enough 
to give the germs a chance. remedy 
Keep the teeth clean. 
DENTIFRICE 
The use of a dentifrice is 
to clean the teeth. Twice a 
day is often enough. 
WHAT DENTIFRICE 
Whatever will clean the 
teeth and do no harm. 
Chalk is the polishing part, soap and water the washing 
part, glycerine to cut the 
tartar, a little flavor to make 
the duty agreeable. 
Sheffield’s creme 
DENTIFRICE 
Paste is the pleasantest 
form ; the collapsible tube is 
the handiest package; and 
mine is the only paste ihat 
keeps soft and does not 
burst the tube. HULKS 
Brush the teeth on going 
to bed, and again on getting 
up in the movning. 
You can no more clean 
the teeth without dentifrice 
than you can clean your 
hands without soap. 
Medium-soft brush, not 
so stiff as to hurt the gums. 
Warm water is better than 
cold or hot; and rinse the 
mouth. Floss-silk is essential, and 
toothpicks are useful, where 
the teeth are at all crowded. 
Where a tooth has begun 
to decay, you cannot clean it, 
you cannot stop the decay ; 
you must go to a dentist. 
DENTIST 
TARTAR 
There is no way to take it 
off the teeth but the dentist’s 
tool. The dentifrice may or 
may not keep it off. 
If you are not within reach of 
a druggist, write to B F Allen 
Company, 365 Canal street New 
York, who will send the denti- 
frice by mail; 25 cents.
