Endodontic therapy is also known as root canal therapy. It is a treatment of the tooth aimed at clearing infection, as well as protecting the tooth from subsequent infections.
The word “endodontic” comes from the Greek words “endo”, meaning “within”, and “odons”, meaning “tooth”.
I am delighted to be able to offer a referral service for endodontic treatments in South East England (London, Surrey, Sussex, Kent).
My aim is to provide high quality root canal treatment in an efficient manner, using the latest techniques and equipment. I enjoy the challenge of treating nervous patients and changing their often unfavourable opinion of root canal treatment.
Once I have received your referral, you will be invited to attend an initial consultation appointment. Following this you will receive a customised treatment plan, so you will always know exactly the treatment you require and how much it will cost. Treatment options may vary depending on your clinical need and personal preference.

I qualified from the University of Athens, School of Dentistry, in 1991. Additionally,
I gained the Diploma in Implants-Biomaterials, a postgraduate qualification in
“Mentoring in Dentistry” from the Faculty of General Dental Practice (FGDP) in
the UK and I hold an MSc in Endodontics from Queen Mary, University of London. (QMUL). I am a Certified member of the European Society of Endodontology (ESE).
Over the years I have focused my activities on Endodontic treatment based mainly in private practices providing my service on a part time and sessional basis in South East of England where I have been living since 2003. I hold an Enhanced Dental Practitioner position within the Surrey and Sussex Area Team, NHS England, accepting referrals for Complex Endodontic Cases.
Since 2009 I have been working as a Specialty Dentist in Endodontics at the Royal London Dental Teaching Hospital and as a Clinical Lecturer at The Bart’s and the London School of Medicine and Dentistry, Queen Mary University of London, where I teach endodontics to undergraduate and postgraduate students.
I hope you will regard me as part of your team and will contact me for your referrals and to discuss cases, and I can offer you help and advice on Endodontics.
My aim is to offer your patients endodontic treatment, carried out in a relaxed environment using the latest techniques and equipment and returning
them to you pain-free, confident and happy with the quality of treatment they have received. Your patient will only be offered treatment for which they
have been specifically referred, with no other involvement with the practice where the treatment will be carried out.
The services I can offer include:
During their consultation patients will be fully informed of the procedure, cost and number of visits.
Most treatments are completed in a single visit but badly infected or complex cases may require a second visit.
The treatments are carried out using high magnification (Global operating microscope and/or Loupes), tooth isolation
(rubber dam) and a variety of modern endodontic equipment and techniques.
On completion of the endodontic treatment patients will be returned back to your care for a definitive restoration and routine dental treatment.
Patients and referring dentists will be able to contact me should any queries arise before, during or after an endodontic case is undertaken.
My aim is to provide high quality root canal treatment in an efficient manner, using the latest techniques and equipment.
I enjoy the challenge of treating nervous patients and changing their often unfavourable opinion of root canal treatment.
If you require endodontic (root canal) treatment or advice, your dentist will make a referral. You may also contact me direct or one of the dental practices where I carry out treatment.
It is important that you find it easy to contact me at any time with queries, fully understand the procedure and the stages of the treatment, as well as the associated costs (all discussed during your consultation) and feel comfortable throughout the treatment.
Your registration and regular dental care will stay with your own dentist.
At the Billis Endodontics clinic you will only receive advice and treatment relating to the root canal treatment for which you have been referred. We will send you and your dentist the details of any treatment you receive at Billis Endodontics.
With proper care, even teeth that have had root canal treatment can last a lifetime. But sometimes, a tooth that has been treated doesn't heal properly and can become painful or diseased months or even years after treatment. If your tooth failed to heal or develops new problems, you have a second chance. An additional procedure may be able to support healing and save your tooth.
Why do I need another endodontic procedure?
As occasionally happens with any dental or medical procedure, a tooth may not heal as expected after initial treatment for a variety of reasons:
In other cases, a new problem can jeopardize a tooth that was successfully treated. For example:
What will happen during retreatment?
First, the endodontist will discuss your treatment options. If you and your endodontist choose retreatment, the endodontist will reopen your tooth to gain access to the root canal filling material. In many cases, complex restorative materials—crown, post and core material—must be disassembled and removed to permit access to the root canals.
After removing the canal filling, the endodontist can clean the canals and carefully examine the inside of your tooth using magnification and illumination, searching for any additional canals or unusual anatomy that requires treatment.
After cleaning the canals, the endodontist will fill and seal the canals and place a temporary filling in the tooth. If the canals are unusually narrow or blocked, your endodontist may recommend endodontic surgery. This surgery involves making an incision to allow the other end of the root to be sealed.
After your endodontist completes retreatment, you will need to return to your dentist as soon as possible to have a new crown or other restoration placed on the tooth to protect and restore it to its full function.
Is retreatment the best choice for me?
Whenever possible, it is best to save your natural tooth. Retreated teeth can function well for years, even for a lifetime.
Advances in technology are constantly changing the way root canal treatment is performed, so your endodontist may use new techniques that were not available when you had your first procedure. Your endodontist may be able to resolve your problem with retreatment. As with any dental or medical procedure, there are no guarantees. Your endodontist will discuss your options and the chances of success before beginning retreatment.
How much will the procedure cost?
The cost varies depending on how complicated the procedure will be. The procedure will probably be more complex than your first root canal treatment, because your restoration and filling material may need to be removed to accomplish the new procedure. In addition, your endodontist may need to spend extra time searching for unusual canal anatomy. Therefore, you can generally expect retreatment to cost more than the initial endodontic treatment.
While dental insurance may cover part or all of the cost for retreatment, some policies limit coverage to a single procedure on a tooth in a given period of time. Check with your employer or insurance company prior to retreatment to be sure of your coverage.
What are the alternatives to retreatment?
If nonsurgical retreatment is not an option, then endodontic surgery should be considered. This surgery involves making an incision to allow access to the tip of the root. Endodontic surgery may also be recommended in conjunction with retreatment or as an alternative. Your endodontist will discuss your options and recommend appropriate treatment.
What are the alternatives to endodontic retreatment and/or endodontic surgery?
The only other alternative is extraction of the tooth. The extracted tooth must then be replaced with an implant, bridge or removable partial denture to restore chewing function and to prevent adjacent teeth from shifting. Because these options require extensive surgery or dental procedures on adjacent healthy teeth, they can be far more costly and time consuming than retreatment and restoration of the natural tooth. No matter how effective tooth replacements are—nothing is as good as your own natural tooth. You’ve already made an investment in saving your tooth. The payoff for choosing retreatment could be a healthy, functioning natural tooth for many years to come.
Why would I need endodontic surgery?
Although there are many surgical procedures that can be performed to save a tooth, the most common is called apicectomy or root-end resection. When inflammation or infection persists in the bony area around the end of your tooth after a root canal procedure, your endodontist may have to perform an apicectomy.
What is an apicectomy?
In this procedure, the endodontist opens the gum tissue near the tooth to see the underlying bone and to remove any inflamed or infected tissue. The very end of the root is also removed.
A small filling may be placed in the root to seal the end of the root canal, and a few stitches or sutures are placed in the gingiva to help the tissue heal properly.
Over a period of months, the bone heals around the end of the root.
Are there other types of endodontic surgery?
Other surgeries endodontists might perform include dividing a tooth in half, repairing an injured root, or even removing one or more roots. Your endodontist will be happy to discuss the specific type of surgery your tooth requires.
In certain cases, a procedure called intentional replantation may be performed. In this procedure, a tooth is extracted, treated with an endodontic procedure while it is out of the mouth, and then replaced in its socket.
These procedures are designed to help you save your tooth.
Will the procedure hurt?
Local anaesthetics make the procedure comfortable. Of course, you may feel some discomfort or experience slight swelling while the incision heals. This is normal for any surgical procedure.
Your endodontist will recommend appropriate pain medication to alleviate your discomfort. Your endodontist will give you specific postoperative instructions to follow. If you have questions after your procedure, or if you have pain that does not respond to medication, call your endodontist.
Can I drive myself home?
Often you can, but you should ask your endodontist before your appointment so that you can make transportation arrangements if necessary.
When can I return to my normal activities?
Most patients return to work or other routine activities the next day. Your endodontist will be happy to discuss your expected recovery time with you.
How do I know the surgery will be successful?
Your dentist or endodontist is suggesting endodontic surgery because he or she believes it is the best option for saving your own natural tooth. Of course, there are no guarantees with any surgical procedure. Your endodontist will discuss your chances for success so that you can make an informed decision.
What are the alternatives to endodontic surgery?
Often, the only alternative to surgery is extraction of the tooth. The extracted tooth must then be replaced with an implant, bridge, or removable partial denture to restore chewing function and to prevent adjacent teeth from shifting. Because these alternatives require surgery or dental procedures on adjacent healthy teeth, endodontic surgery is usually the most biologic and cost-effective option for maintaining your oral health.
No matter how effective modern artificial tooth replacements are—and they can be very effective—nothing is as good as a natural tooth. You’ve already made an investment in saving your tooth. The pay-off for choosing endodontic surgery could be a healthy, functioning natural tooth for the rest of your life.
At your first consultation, the history of your problems will be discussed. A clinical and radiographic examination, based on the referral,
will be carried out. At this stage, we will fully explain the treatment proposed,
and we will provide you with a written treatment plan outlining costs and the number of proposed appointments.
Following the consultation, an appointment will be arranged for you and the endodontic treatment will be carried out in accordance to European Society of Endodontology Guidelines.
The referring dentists will be kept informed of their patients' progress and a discharge letter and a copy of the final radiograph will be sent upon completion of the treatment. The patient will also receive a copy of this.
No other treatment, other than that for which the patient has been referred, will be undertaken.

Knocked a tooth out?
Don't panic! Here's what to do to help save your tooth:
Step 1: Pick the tooth up by the crown only (do not touch the root)
Step 2: Lick the tooth clean if it is dirty, or rinse it in water
Step 3: Stick the tooth back in position (adult teeth only). Never try to re-insert a baby tooth
Step 4: Bite on a handkerchief to hold it in place and go straight to the dentist
If it is not possible to put the tooth back in position, place the tooth in milk and go straight to the dentist (out of hours go to A&E). For more details see poster below:
Broken a tooth?
Tooth fragments can sometimes be stuck back into position. Find the fragment (keep it safe) and go to the dentist to see if it can be glued back into position. Don't worry if you can't find the fragment as a tooth-coloured filling can be used to build the tooth up.Further information : www.dentaltrauma.co.uk

The word 'Endodontics' comes from the Greek meaning 'inside' (endo) the 'tooth' (odons). Endodontic treatment, also known as root canal (treatment), is a treatment of the tooth aimed at clearing infection, as well as preventing the tooth from subsequent infection. This damage may occur for a variety of reasons, for example, dental caries (decay), trauma, or damage resulting from old fillings, crowns etc. The alternative to root canal treatment is often extraction of the tooth.
Endodontic treatment can often be performed in one or two visits and involves the following steps:
The endodontist examines and x-rays the tooth, then administers local anaesthetic. After the tooth is numb, the endodontist places a small protective sheet called a “dental dam” over the area to isolate the tooth and keep it clean and free of saliva during the procedure.
The endodontist makes an opening in the crown of the tooth. Very small instruments are used to clean the pulp from the pulp chamber and root canals and to shape the space for filling
After the space is cleaned and shaped, the endodontist fills the root canals with a biocompatible material, usually a rubber-like material called gutta-percha. The gutta-percha is placed with an adhesive cement to ensure complete sealing of the root canals. In most cases, a temporary filling is placed to close the opening. The temporary filling will be removed by your dentist before the tooth is restored.
After the final visit with your endodontist, you must return to your dentist to have a crown or other restoration placed on the tooth to protect and restore it to full function.
If the tooth lacks sufficient structure to hold the restoration in place, your dentist or endodontist may place a post inside the tooth. Ask your dentist or endodontist for more details about the specific restoration planned for your tooth.
"Could not recommend highly enough. I'm a nervous patient and George made me feel comfortable and safe."
"I found Dr Billis on doing an internet search and he was one of the few dentists that actually has the full qualifications to do root canals. I was quite nervous about having the root canal done as it was my first one but after doing some research I came to the conclusion that he was the best person for the job. My dentist had tried to persuade me to spend a fortune at a Harley Street clinic. The treatment was gently done and I had no pain or trouble with my tooth and it has settled down nicely and I didn't even need a new crown as Dr Billis managed to drill through my existing one. I thought that the surgery in Crawley offers a very affordable treatment for patients like myself living in London and needing a root canal. I was willing to travel south to have the treatment done in Crawley which saved me a lot of money. I would highly recommend Dr Billis."
Director Innovative Relationship Marketing
“I am a very nervous patient and when my dentist suggested that I needed root canal treatment to save the tooth I was terrified. But on the consultation appointment Dr Billis made me feel relaxed and comfortable. He explained everything with professionalism and he answered all my questions even the ones I knew were ‘really silly’ because of my fear. After the treatment, I felt I really don’t have to worry anymore for my dental appointments. Well done and thank you!!”
“Excellent treatment, first class. Would recommend to anybody. Thank you!”
“Dr Billis, Thank you very much for the incredible work you have done! You and your team are so experienced and very caring. Felt good afterwards!”
“Dear George, Adam and dentist nurse,
I would just like to thank you all for the wonderful work you did on my tooth last month, the thought of having the root canal treatment was very daunting although essential, but you were great. I felt reassured at every step and even though it took 2 appointments it has been very well worth it. I can’t tell you how it has changed my life, sounds silly I know but honestly it has, the pain I was in before affected my whole day, I couldn’t eat, drink, brush my teeth or even breath with my mouth open! But all that pain has now gone. And the procedure wasn’t half as bad as I was expecting either! There was obviously no pain during the work and nothing a couple of Ibuprofen didn’t fix after the anaesthetic wore off and then by the next morning pain free.
Thank you all so much.”
“George is without doubt the best dentist I have ever met! It was a pleasure to have the root canal treatment with him. His work is spot-on! He is outstanding and the service impeccable!”
“Dr Billis and his team have been fantastic. It was my first experience with such treatment and they made it an easy one for me! Highly recommend for root canal treatment!’
“The information, the reassurance, the kind approach and the results made me feel that it was worth it!
“Everything went smoothly, from the moment I entered the practice until the moment I left. I expected a lot of discomfort and pain but during the procedure I didn’t feel anything bad. Root canal treatment is not as bad as I thought! I would recommend Dr Billis for saving your tooth!”
“I have been referring all my endodontic patients to Dr George Billis for the past year, I have been very happy with his excellent work. All my patients have commented that he is a nice man and that he explains all treatment in detail and that he is reassuring and also makes them feel very comfortable and confident in his ability. I would highly recommend Dr Billis as an Endodontist.”
Dr. Nigel Graves
“I have had the pleasure of referring patients for endodontic treatment to Dr George Billis for the last four years. He has proven to be an excellent endodontist, making confident diagnosis and decisions. As a periodontist, I have to deal with many endo-perio cases and George has given me great support and helped me achieve the best possible results for my patients. Dr. George Billis has excellent interpersonal skills, is honest, sincere and completely reliable.”
Dr. Stavros Kolonidis
“I have been referring patients to Dr Billis for the last two years. All my patients come back with compliments for his attitude and care. I am always pleased with his work and with the information he provides me. I myself had to have a root canal treatment and even as a dentist knew the whole process, his clinical skills and experience made me feel comfortable and reassured. I highly recommend Dr Billis to my family, friends and off course my patients.
Dr. Antoaneta Ciotaru
“I refer my endo cases to Dr George Billis as I have full confidence in him. He is always happy to give advice and help with difficult cases. Patients love him, feel very comfortable with him and they are happy with their treatment.”
