About Your Tooth
Your tooth consists of two main parts:
What is Endodontics?
In order to preserve a tooth that is 'dying', it is necessary to remove the infected and inflamed pulp tissue from inside the roots to prevent further spread into the surrounding tissues. The roots are then filled and sealed. This procedure is known as endodontic or root canal therapy. Endodontic therapy is concerned with removing only the pulp from the root canal, so the root and tooth will remain intact and continue to function normally in jaw bone after the treatment.
Afterwards, you return to your own general dentist who will place a permanent filling and crown on the tooth to protect it's long-term function.
Who performs Endodontics?
Your own general dentist has received basic training in endodontics during their degree course at dental school. BUT they may refer you to a Specialist Endodontist due to the complexity of an infected tooth or simply to ensure maximum predictability of health of the tooth if expensive, cosmetic, or complex restorations are to be made.
Endodontists have completed formal University-based postgraduate training. Dr Bhanderi is registered as a Specialist in Endodontics with the General Dental Council.
This pulp may become irreversibly damaged because of infection associated with decay, very deep fillings, repeated dental procedures, a crack in the tooth, trauma, or advanced periodontal (gum) disease. Once it has been confirmed that the pulp is irreversibly damaged then the pulp must be removed and the root canals thoroughly cleansed, disinfected, and filled.
Decay - When decay in a tooth becomes so extensive that it penetrates into the pulp of the tooth, then the bacteria that are associated with the decay infect the pulp. Eventually, the pulp and all its contents will become inflamed (sometimes causing pain) and will die. The infection will then spread throughout all the root canals and may seep out through the end of each root into the surrounding jaw bone.
Pain and swelling - If the infection is left untreated for a considerable time then it will percolate through the end of the roots and cause an infection in the jaw bone. Sometimes this is very aggressive, called an abscess. Other times it can remain quiescent, slowly destroying the jaw bone at the end of the infected roots. It may then spread up the side of the tooth's roots and infect the supporting bone and gums, with or without any symptoms.
The whole procedure is performed under complete local anaesthesia, so you will feel no pain and will always be awake. If at any time you feel discomfort, I will stop immediately and identify the cause and try and alleviate it. We then will 'isolate' the tooth by wrapping it up with a clip and rubber sheet (a 'rubber dam').
You can find more information on the procedure on the British Endodontic Society website.
Signs and symptoms to look for include prolonged and spontaneous pain, prolonged sensitivity to cold but especially to hot, swelling and tenderness in the overlying gums, and sometimes discoloration of the tooth. But occasionally there may be no other obvious symptoms.
If the tooth looks too infected at the first visit or there have been problems in identifying or cleaning all the root canals, then the tooth will be filled with an antiseptic dressing and you will need to return for another appointment for the final root-filling.
Usually, the whole appointment will last for between 1-1½ hours. I will keep you informed throughout the procedure.
Occasionally, we may want to review the tooth after the root filling has been done on a 6-monthly basis in order to monitor your healing response. These appointments are very important as they allow us to intervene swiftly if the situation appears to be deteriorating. These review appointments are very short and simply involve looking at the tooth and taking an x-ray to see how well the bone and gums are healing. There is usually no further charge to you for these short review appointments.
Usually we will ask your own dentist to keep an 'eye on things'.
Immediate Post-treatment care
For the first few days after treatment the tooth may feel a little 'achy', especially if there was pain or infection before the procedure. This discomfort is sometimes caused by the fact that we have instrumented and disturbed the infected area just outside the end of the roots and the pressure of applying the root-filling. This can be relieved with over-the-counter or prescription medications.
Evidence shows that taking an anti-inflammatory just before and after the treatment (e.g. 400 mg Ibuprofen, "Nurofen Plus"), or if you have a medical condition that precludes you taking his type of painkiller (e.g. asthma, gastric ulcer), then 1000mg Paracetomol will help in minimising the discomfort.

Others causes of 'toothache':
Momentary sensitivity to hot or cold foods - this generally does not signal a major problem. The sensitivity may be caused by a loose filling or by gum recession that exposes small areas of the root surface (dentine). Try using 'sensitive formula' toothpastes. If this is unsuccessful, see your dentist.
Sensitivity after dental treatment - Dental work may inflame the pulp inside the tooth, causing temporary sensitivity. Wait 4 to 6 weeks. If the pain persists or worsens, see your dentist.
Lingering pain after hot or cold foods - This probably means the pulp has been damaged by deep decay or physical trauma. See your general dentist who may need to refer you to an Endodontist to save the tooth.
Sharp pain when biting down on food - There are several possible causes of this: a loose filling or a crack in the tooth. This may damage to the pulp tissue inside the tooth. See your general dentist for initial evaluation. If the problem is a cracked tooth, your dentist may need to send you to an Endodontist to treat the dying pulp, followed by a crown. The prognosis of the tooth is determined by the extent of the crack.
Constant and severe pain, swelling of gum and sensitivity to touch - A tooth may have an abscess causing the surrounding bone and soft tissues to become infected. Your general dentist will need to immediately assess the extent of the infection and then may refer you an Endodontist to try and save the tooth. Take over-the-counter analgesics until you see the Endodontist.
Dull ache and 'pressure' - Pain in upper back teeth (the premolars and molars) may be caused by sinusitis (result of a viral cold or influenza) mimicking toothache. For sinus headache/pain, try over-the-counter analgesics or decongestant sinus medications and see your GP. If persistent then consult your general dentist who may need to investigate further.
Other causes of dull aches/tenderness in teeth - grinding of teeth (a condition known as 'bruxism'), or periodontal infection (in the gum and surrounding jaw bone) may also cause this type of ache.
