Root Canals

What are Root Canals

Root Canals are actually one of the most common dental procedures in Ireland. If your tooth has become infected, or you've damaged its nerve beyond repair, this procedure can save it: through removal and disinfection by filling in any remaining space with sealant to keep bacteria out. Root canal treatment typically takes an hour-long appointment for preparation (such as x-rays), then generally two appointments spaced about six weeks apart - with some exceptions, but be sure to ask before deciding on extraction!

A root canal is designed specifically to eliminate bacteria from the infected root cavity, preventing reinfection while saving natural teeth that would otherwise need extracting under more extreme circumstances like severe damage caused by infection, among other things including broken off pieces of roots left behind. The procedure removes diseased nerves and blood vessels, leaving behind an empty space for filling with special cement, hence alleviating pain associated with dentin hypersensitivity (which often occurs when there's exposed raw nerve).

What is a Root Canal used to treat?

Root canals are an essential procedure for teeth that have been cracked or otherwise injured. This is because they help seal up the tooth and prevent any infection from travelling through to nearby parts of your mouth, which could result in a serious dental emergency. A root canal may also be necessary if you’ve had old amalgam fillings replaced with composite (white) ones as these sometimes lead to cracking over time; this causes pain when chewing on one side of your jaw.

What are Endodontics

Endodontists specialised in the treatment of the inside of the tooth (tooth pulp) to save it from tooth pain, disease, and infection. The tooth pulp has blood vessels, nerves, and connective tissue. It can get inflamed or infected, so an endodontist ensures your root is in great shape and fixes it when something goes wrong.

They receive at least two more years of training that helps them perform especially root canals, which is a special procedure to save an infected or decayed tooth. They also perform apicoectomies.

Root Canals

It's a procedure to clean the infected pulp area, relieve pain and save the tooth. Most infections are caused by advanced decay or a deep cavity very close to the pulp, so sometimes a root canal is the best and only way of saving a damaged tooth. They remove infected material from the pulp-filled cavity or root of a tooth, cleaning out the cavity and replacing the infected area with inert material, which saves the tooth.


If a root canal isn't enough to remove an infection that affects the root and the adjacent tissues, your endodontist will recommend surgery to save your tooth. The most common type is apicoectomy. It treats an infection by removing a tip of a tooth root, where bacteria lie. The hole is then cleaned and sealed.

Endodontic retreatment

Occasionally, a root canal treated tooth doesn't heal properly because root canals are narrow, curved or branched, and it may be difficult to clean them, or even because the tooth may have extra canals that weren't located during the initial procedure. Your tooth can become painful or diseased after the treatment that didn't clear up the initial infection, so endodontic retreatment helps you save your tooth.

Traumatic dental injuries

Traumatic injuries to teeth as a result of accidents or sports injuries can cause tooth pulp to become necrotic. It involves chipped teeth that weren't fully dislodged, and this treatment depends on the location and severity of the injury, so we at College Gate Dental Clinic will take a look at it and give you a solution, especially if your neighbouring teeth suffered additional harm which requires dental examination.

Follow the instructions of your dentist and spend the rest of the day at rest. Take your medication as indicated, eat soft foods, be careful when brushing the tooth, chew on the other side of your mouth if possible, and most importantly, keep track of your progress. Avoid eating after the procedure and brushing your teeth aggressively.

Frequently Asked Questions

Questions about Root Canals?

A root canal may take around 90 minutes in general, and it’s normally performed in one appointment. However, complex cases may take up to 3 hours to complete, and they are normally done by an endodontist. 

It may be a bit scary, but there will be little to no pain because of the anaesthesia that will be used by your dentist to numb your tooth and surrounding area so that you are comfortable and at ease. 

General symptoms to have a root canal done are a hole in your tooth, pain while chewing, swelling of the gum or face, sensitivity to heat or cold and a dark discoloration of your tooth. If you notice any of these signs, a cavity may have formed, and you need to call us as soon as possible to handle the situation.

It’s perfectly fine if you feel discomfort or tenderness in the surrounding area because the gums and nerves may have been irritated, but if you feel tooth pain when you apply pressure to it after a few days, there must be a problem with it, so call us, and we will take a look at it.

You will normally feel mild pain, but don’t worry, it will go away after a few days. If you are very sensible and it bothers you, you can take painkillers such as ibuprofen, and you will feel no pain.

Unless you were sedated with general anaesthesia, you can drive home safely because local anaesthesia only numbs the tooth and surrounding gum, so you don’t need to worry, you can drive.

During the procedure, your endodontist will remove the infected pulp and clean the inside of the root canal, then they will fill the space. If you require a crown, you may have to come back another day.

It’s one of the most usual procedures that will save your teeth and prevent the need for dental implants. It implies the removal of the infected nerve or dental decay from the root of your tooth so that your tooth is back to being in top shape.

A root canal treatment will preserve your tooth cleaning out the nerve tissue infected so that you don’t need to extract it. Thanks to a special root filling, we can help you restore the tooth to its prior state in order to avoid paying for an implant. 

Your dentist will use local anaesthesia to numb your tooth and gums, so you will feel no pain at all! Besides, with today’s technology there are no added complications. You don’t need to worry.

Yes, it’s usually successful at saving your tooth with a high success rate. 9/10 teeth treated with a root canal survive up to 10 years. If you have a crown fitted to your tooth as well, it will increase your survival rates.

It may discolour after a root canal treatment, so in case it does because the dentin darkened over time, there are some options available for you. Don’t hesitate to contact us at College Gate Dental Clinic, and we will offer you the one suited for you.

A root canal treatment might take from 1 to 3 hours, so there are instances where we need two appointments to perform such a procedure.

It’s normal that you feel mild pain for a few days after, but if you have good oral health habits and take care of your tooth, this discomfort will fade away. If it won’t go, call us to make an appointment and we will look at it.

In some instances, you may have problems with the filling used to cap your root canal, so if it hurts when you bite, it means that filling was insufficiently filed, and the pressure of your bite is transmitted to one tooth and compressed into the socket.

You should eat soft foods such as fruits, yoghurt, eggs, hummus, mashed vegetables, and pancakes. You should avoid carrots, apples, gum, candy, or nuts, because they may pull out the filling. Avoid alcohol as well.

Yes, it’s possible that you need two root canal treatments to be performed in the same tooth, as some of them have two roots, but it’s difficult for the dentist to discover. If you mean your tooth needs another root canal after a while because it decayed and you need another one, it’s also possible. 

They usually heal after a few days, but sometimes and if your case is complex, it can take up to two weeks even.

It’s fine if your tooth turned darker in colour because deposition of pigment from the nerve may cause your tooth to turn grey or brown. If you want its colour back to how it was, you can whiten it. 

Nerves are not killed during the treatment. It consists of removing the inflamed pulp tissue, and afterwards, disinfect it and then seal it with a material called gutta-percha. So, your nerves don’t need to grow back.

When a tooth is decayed, the infectious process builds pressure within the tooth, which results in pain. Unless your dentist removes the degraded tissue, this process will continue, and ultimately, the tooth will die.

It’s the removal of the tip of the root, named apex. The aim of this minor surgery is to get rid of any infection following a root canal treatment, and it is performed if there is no way your dentist can seal the root with a normal root filling.

It’s necessary to save your tooth from the infection arisen after a root canal treatment while keeping your tooth and crown intact, so if you feel pain or swelling after a standard root canal procedure, you should contact us.

A Glidepath in endodontics is a radicular tunnel from the canal orifice to the physiologic terminus of your tooth. Without its discovery in case it is present or preparation if not, endodontics cannot be achieved.

Endodontics focuses on the connective tissue, nerves, and blood vessels of a tooth. Endodontists perform treatments such as root canal treatments or apicectomies. 

“Endo” is the Greek word for “inside”, and “odont” means “tooth.” Thus, endodontics involves the inside of the tooth called the pulp, which is a soft tissue under the enamel and dentin.

Root Canals Treatment Process

What is the process in getting root canals?

A root canal treatment is performed by a dentist and typically takes two or three visits to complete. These appointments include the preparation of the tooth, filling the root canal, and finally completing the treatment with a crown.

The first visit should be a consultation before any work is done. This is an evaluation to determine if the procedure is necessary and if you are a candidate for root canal therapy. Our dentist here at College Gate Dental Clinic may take x-rays of your teeth at this point or refer you to another doctor for this service. There will also be an examination of your teeth and gums, as well as any other problems that might exist that need to be addressed.

A root canal procedure begins with a cleaning of your teeth that includes removing plaque and tartar. If you have experienced a broken tooth, your dentist may have to perform an emergency root canal right away. In some instances, your tooth can be saved with a crown and sometimes it will need to be extracted.

The next step is drilling into the tooth to access it at its center, which is called the pulp chamber. This is where the nerve of your tooth is located. Once there, the dentist will clean out all infection and inflammation. Then, they will make a space to fit a temporary filling called an obturator.

This is usually done with gutta-percha – a pure latex rubber material that contains disinfectants. This creates a barrier between the tooth and the nerve, which is where bacteria can’t enter. The dentist will make a final impression of your tooth at this point. From here, they will create a permanent filling that includes cement and porcelain.

After your final appointment to place the crown on your teeth, you are free to proceed with your normal life again.
