Underlying problem for root canals?

Question

I know what root canals are, but is bad oral hygiene the only cause for one?

Answer 1

Not necessarily. Sometimes ones saliva is so acidic that the enamel on the tooth is eaten away , causing tooth to  decay faster , Also due to hereditary and genetic factors tooth  may be too  soft and decay faster . Lack of certain vitamins and Calcium also can cause tooth decay which would lead to root canal eventually.

Answer 2

No, trauma is a main cause (knocking your tooth, being punched in the mouth, any hard bump may cause the nerve to die off... Deep decay which eventually makes it to the nerve..

People who REALLY grind their teeth can wear away the enamel and dentine to eventually expose the nerve .. fractured or cracked teeth allow bacteria into the nerve canal causing infection and necrosis.

Gum disease doesnt cause a nerve to die....(unless decay is under all the calculus & it eats its way to the nerve) it causes receeding gums, bad breath, sensitive teeth, stroke and heart disease...

Answer 3

of course not, basically anything that could cause ur tooth nerve be damaged meant u need a root canal. for me though, it's because of my huge cavity, but if u break your tooth completely or something like that, i'm sure you'll also need one
