Tiny organism called germs cause tooth decay.
This hole or cavity in the tooth should be filled by a
dentist. Otherwise, it will get bigger and bigger.
Eventually you will end up with a very bad toothache
and the affected tooth may even have to be removed.
Germs grow and multiply on and between the teeth.
They form a white material called plague on our teeth.
Germs grow and multiply on and between the teeth.
They form a white material called plague on our teeth.
If the plague is not removed, it becomes a hard material
called tartar.
Tartar can spread to other teeth and make the gums red and sore.
The gums may even bleed.
The gums surrounding the teeth may become weak.
Hence, the teeth become loose.
Gum diseases can cause bad breath.
