What happens during a root canal?

So you want to know what to expect from endodontics? Well, that is not as straightforward as it may seem. Although most procedures can be performed at our clinic, particularly complex cases may be referred on to an endodontic specialist. For the more common treatment of root canals Essex let’s look at the normal steps and likely outcomes.Root Canals Essex

It is very unlikely that an endodontic treatment will be completed in a single visit, but more likely over two. If there is an active infection, there will be a further pause in treatment and antibiotics will be given to resolve the infection before dental work can begin.

The preparation

Endodontics is by definition under the tooth. Our dentist will start with a set of X-rays, so they can see the scope of the problem and prepare accordingly. Most of the time, an anaesthetic is administered unless the infection has destroyed the nerve, leaving the tooth painless.

An oral dam will be created; the rubber barrier isolates the affected tooth and prevents the patient from swallowing debris generated during the procedure.

Cleaning and pulp extraction

The top of the tooth is opened to expose the pulp. From this, the infected pulp is removed via gentle scraping. If any of the abscess beneath the tooth remains it will be drained.

The root bit of the root canal

With the tooth de-pulped, the canal would be visible in a normal tooth; the canal is very narrow, far too narrow to clean and fill.

So a set of files is used to progressively widen the canal. This is not a quick process, it can take two hours and is therefore done in two sessions.

Not all teeth have the same number of roots, but in general, the front teeth have one, molars have two or three and some wisdom teeth have five. The number of roots varies on ethnicity, and the more roots a tooth has, the longer the root canals Essex will take.

To pause any root canals Essex our dentist will place a sterilising solution into the tooth canal and seal the top with a temporary filling. If at any point the signs of an infection reoccur, like a discoloured swelling or a raised temperature, the treatment will be stopped and a course of antibiotics will be prescribed.

Once the tooth is re-sized and fully cleaned, the filling can begin by replacing the removed pulp.

There is a higher risk of breaking a root-filled tooth than an untreated tooth, so depending on how much of your tooth remains our dentist may suggest a crown. If the tooth was very damaged there may not be enough remaining to support a crown; if so, a peg can be placed in the filled root to support a crown.

You should expect the lifespan of a filled tooth to be shorter than natural teeth, but with good oral hygiene eight to ten years is normal.

A filled tooth may darken after filling, this is normal, but you may wish to consider tooth whitening if a front tooth is affected.
