Root Canal Treatment : A root canal treatment is a dental procedure to remove inflamed or infected pulp on the inside of the tooth which is then carefully cleaned and disinfected, then filled and sealed. Root canal treatment is designed to eliminate bacteria from the infected root canal, prevent reinfection of the tooth and save the natural tooth.
What happens during root canal treatment? 
There's no need to be worried if your dentist or endodontist prescribes a root canal procedure to treat a damaged or diseased tooth. Millions of teeth are treated and saved this way each year, relieving pain and making tooth healthy again.  

Inside your tooth, beneath the white enamel and a hard layer called dentin, is a soft tissue called pulp. This tissue contains blood vessels, nerves and connective tissue, which help grow the root of your tooth during its development. A fully developed tooth can survive without the pulp because the tooth continues to be nourished by the tissues surrounding it.

A modern root canal treatment is nothing like those old sayings! It's very similar to a routine filling and can usually be completed in one or two appointments, depending on the condition of your tooth and your personal circumstances. Getting a root canal is relatively painless and extremely effective. You'll be back to smiling, biting and chewing with ease in no time.
Saving the natural tooth with root canal treatment has many advantages:

       Efficient chewing

       Normal biting force and sensation

       Natural appearance

      Protects other teeth from excessive wear or strain
How do you know if you need a root canal?

Root canals are needed for a cracked tooth from injury, a deep cavity, or issues from a previous filling. Patients generally need a root canal when they notice their teeth are sensitive, particularly to hot and cold sensations. 

There are a few symptoms that mean you might need a root canal-

      Severe pain while chewing or biting

      Pimples on the gums
      A chipped or cracked tooth

      Lingering sensitivity to hot or cold, even after the sensation has been removed. 
      Swollen or tender gums

      Deep decay or darkening of the gums.
