If you have a tooth whose internal structures are damaged, you may
benefit from root canal therapywhich is beneficial as of [URL=http://
www.rajkrishnan.com/]Root Canal treatment[/URL]. Also called
endodontics, root canal therapy can restore your tooth to its state of
health by treating the damaged part of your tooth. You may experience
symptoms ranging from occasional sensitivity to hot and cold foods, to
constant throbbing or a dull ache, to pain on chewing. Your dentist
can assess the extent of damage by a comprehensive dental examination.
Your dentist takes a dental history, examines your teeth and gums, and
x-rays your teeth to examine the underlying roots and bone.

Your dentist will begin by asking if you have any symptoms such as
throbbing, aching, or pain when you chew. You may be asked about
previous dental work or injury to your teeth and any medical
conditions you may have. After your history is taken, your dentist
will examine your teeth - looking for cavities, assessing the
condition of any fillings you already have, check to see if your teeth
are sensitive to hot or cold, check for loose teeth, tap on your teeth
to check for pain, and evaluate the condition of your gums.

X-rays allow your dentist to see the inside of your teeth and the
surrounding bone. With an x-ray, your dentist can detect any unhealthy
changes in your teeth or bone, irrespective of whether they are
causing any symptoms or not. Your tooth has two basic parts: the crown
is the part you see above the gum, and the roots anchor your tooth to
your jawbone. Inside the crown and roots is soft tissue (pulp) that
helps keep your tooth nourished.

Crown: An outer enamel layer and the dentin inside protect the tooth's
underlying structures and prevent bacteria from entering the tooth.

Root: the root canals house the pulp and extend to the underlying
bone. The pulp helps nourish the tooth and is made up of tiny blood
vessels and nerves. The blood vessels carry nutrients to the tooth,
and the nerves give feeling to the tooth. The bone holds the tooth
with the help of tiny ligaments attached to the roots. The pulp tissue
enters and exits through openings at the root tips.
