Root Canal Treatment

Also known as endodontics, root canal treatment becomes necessary when a tooth’s centre, or its root canal system, becomes infected.

The root canal system extends from the tooth’s crown to the root’s end and contains dental pulp, the soft tissue with blood vessels and nerves.

Bacteria in the mouth invade the tooth if there is tooth decay, an injury, or if fillings leak. As bacteria and the substances they give out pass through the root canal, the tissues at the end of the tooth swell up and become red. The tooth then becomes very painful, and, if there is an abscess, the whole face may become swollen.

Once the dental pulp has become infected, this has the potential to spread across the tooth’s root canal system.

Sometimes, the tooth may become darker in colour, and this could be an indication that the tooth’s nerve is either dying or has already died, and so needs to be dealt with through root canal treatment. In time, the end result could be an abscess or gumboil – an area of inflammation that can become filled with pus and cause the tissues surrounding the tooth to swell up.

The symptoms of a pulp infection include pain on chewing or biting, a tooth which has become loose, or pain when eating or drinking things that are hot or cold.

As the tooth pulp dies, sometimes these symptoms can go away, so that it may feel as though your tooth has healed. But what is really happening is that the infection is spreading across the root canal system.

Symptoms of having an abscess can be quite wide-ranging – from having a dull ache to acute pain. Equally, the tooth may feel rather tender as you bite.

The good news is that root canal treatment should involve no more discomfort than you may experience when having a standard filling done. While you may feel some tenderness in your tooth following treatment, this will reduce in time.

When do I need root canal treatment and what is Involved?

You only need root canal treatment if it has become clear that a bacterial infection has harmed the dental pulp, which can be established with an X-ray. But if a tooth has become infected, the pulp will not heal without treatment, and leaving it untreated could make matters worse. Equally, if the infection in your tooth really becomes established, the root canal treatment may be less effective.

Without root canal treatment, removal of the whole tooth may be the only viable alternative. But of course, it's far better if you can avoid this.

The reason why antibiotics will not be effective in dealing with these infections in the long-term is because their active ingredients will only work if they can get to the infection site via your bloodstream, and the bacteria are in the root canal system itself which killed off the blood supply.

Repeated antibiotic courses could mean that the bacteria eventually adapt and develop new ways of resisting the effects of the antibiotic, so that the medication no longer works.

The ultimate goal of root canal treatment is to get rid of all the infection from the root canal. Afterwards, the root is thoroughly cleaned and then filled so that further infection doesn’t occur.

For most courses of root canal treatment, you will need to see your dentist at least twice. During the first visit, the infected pulp will be removed, and at the same time if there are any abscesses, these can be drained. After the cleaning of the canals, they will be shaped and slightly enlarged in preparation for receiving the root filling material. Your tooth will then receive a temporary filling and the tooth will be left to settle down. During the next appointment, the tooth is checked again. Once it’s confirmed that the infection has gone completely the tooth can then receive the root filling which consists of a bio-compatible material that completely seals off the root canal system of the tooth. 

If you are wondering how the appearance of the tooth will be affected, today’s dental techniques mean that the tooth should not darken after treatment. If discolouration does occur, there are a number of options for restoring the tooth’s natural colour.

Rates of success for this routine dental procedure are very high, but if the infection returns, treatment can sometimes be repeated.

Your tooth will be perfectly safe after treatment, and should be treated just like the rest of your teeth, and cleaned and checked up in the same way.

I have been a patient of Dr. Ovidiu Maurer’s for almost two years now and quite simply he is the best dentist I have ever had. Ovidiu is so thorough; obviously highly skilled and talented and deeply interested in all aspects of his work, he is still open to learning. Ovidiu takes time during examinations to explain what he will be doing and to give the best advice, a rare and invaluable humility. His approach and his treatment are meticulous but imaginative when appropriate. As soon as you walk into the building you feel welcomed and confident that you will receive the best possible care, and you do. I was completely amazed by the quality and range of equipment, hygiene and generally relaxed, professional atmosphere. I am absolutely delighted with the finished result and would not hesitate to recommend him to anyone considering dental implants and not only. Thank you Ovidiu and all your Team Cristina Botan

Cosmetic Dentist Harley Street - Where do I begin...... Firstly, a massive thank you to David, Practice Manager and Dr Maurer. I have never come across such polite, warm, friendly professionals and not forgetting the nurse, Justina. The experience is one that you will never forget, it is first class and I cannot highly recommend this service enough. I am thankful for the day I picked up the phone and dialed Diamond Dental of Harley Street's number. Immediately, I just somehow knew that I would be in good hands just from a mere telephone conversation with David. I had been to other dentists and do have some genuine horror stories so I was obviously nervous. However, the first consultation was superb, friendly professional and the advice given was genuinely for my benefit and not just a money making scheme as experienced at other practices I had visited. Dr Maurer is every bit the professional, was attentive and I could tell very passionate about his job so was seeking genuine perfection. He was thorough and gave me the best treatment option. He talked me through the management plan for my teeth and even talked me out of having veneers so saved me money! He will not let you walk away until he is absolutely happy with your teeth. Dr Maurer has created a beautiful set of teeth without any invasive treatment thank you so much.  I am sad that I now no longer need to visit the dentist, but I will find reasons to go back, Harley Street is a beautiful area! I am recommending all my family and friends.  Go on call them you will not be sorry. They are such a friendly bunch you will feel comfortable with them immediately.

Emergency Dentist Harley Street - I write this testimonial long after I had treatment but nonetheless, even on holiday from Spain, I found a bit of time to write, and to thank Dr.Maurer at Diamond Dental of Harley Street for his help. I came in with a severe sub lingual abscess with lots of complications, after spending 2 weeks in Euston College Hospital I had no result but thanks to Dr.Maurer's extra professional help I got better in just days and the complications are no longer. He is very patient, always careful with an inclination towards the customer, all in a clean, friendly, beautiful and healthy environment. I have, and will recommend Dr.Maurer to anyone who has dental problems, or wants to maintain a healthy denture. Thank you guys.

Hygienist Harley Street - I think this is probably the best Harley Street Dentist I have ever been to. I phoned up to ask about getting my teeth cleaned, and was very impressed that it would be done by an actual dentist, not some "hygienist" armed with nothing more than floss. This mattered as I had not had my teeth properly cleaned for 5 years and they were in a terrible state. On the day, the dentist went far beyond the call of duty, and performed miracles. He really put some effort into it and got rid of years of tartar build up and threw in some much needed deep cleaning. Several months later I'm still admiring my teeth and how good they look now. The dentist himself and his assistant were extremely polite and efficient and they didn't waste my time trying to charm me, or foist their products on me, did not patronise me but explained everything in a proper scientific way that I could understand, which was a huge relief. Most important of all, I did not feel at any point that the advice I was being given was simply to present the largest invoice possible - which has also happened to me in a lot of other places. I would recommend this Harley Street practice to anyone, and will definitely be returning.

Veneers Harley Street - Having been to numerous Harley Street dentists looking for a way to fix a front tooth veneer that had cracked in two, I found these guys by accident and visited their website. Rather than a new veneer or a full blown cap, I decided to investigate the composite veneer. From the careful way the anesthetic was administered (NO PAIN!) to the sheer care and effort that was used to make me happy with the outcome, I can't recommend this Harley Street dentist more. The end result was like nothing I had experienced before - much more translucent than a crown, much more real than a veneer. Worth every penny. I want to come back to this Harley Street dentist to replace some of the work I had done in past years - it all looks so much more natural.

Veneers Harley Street - I came all the way from Bath especially to see DR. Maurer at his Harley Street practice to have 4 front veneers. Firstly I want to say a BIG thank you to him for the amazing work he has done. I have had nothing but compliments since receiving my veneers. People always tell me how perfect my teeth are and are shocked when I tell them they are veneers, the veneers have caused jealousy between my friends. As I was going in to hospital to have surgery the surgeons and nurses commented on my teeth and did not believe me when I said they were veneers...Now if surgeons who need an eye for detail can't even tell then all I can say is Dr. Maurer has an incredible eye for detail. He has given me the perfect smile yet looking so natural, my smile fools everyone, even the experts! As I walked into the clinic I could tell immediately that I was only going to get the best and I was right. The clinic is fresh, clean and stunningly beautiful. I instantly felt relaxed and so excited at the same time. The clinic is perfect, the doctor is perfect and my smile...PERFECT! Hands down this is the best Harley Street Dentist you will find

Emergency Dentist Harley Street - I had not been to a dentist for many many many years due to a phobia. Unfortunately I broke a tooth last week and need emergency help. I had to find somewhere that would be patient, helpful and know how to handle a hysterical woman! This is the place...... Amazing. Dr Maurer and his staff were fantastic with me. My tooth is fixed and I even plan on going back soon for some cleaning. Highly recommended.
