Root canal fillings: methods of root canal filling

No cavities teeth and root canal is difficult to imagine modern dentistry, because these procedures are the most popular, because they allow to keep the tooth and restore its appearance. Sealing – the process is time consuming, there are several kinds of material for its production, as well as some recommendations for the care of the tooth after the procedure, all people have to learn before going to the dentist.

When you need a filling

Sealing – the method of treatment of morphological changes in the tooth, the procedure allows not only restore appearance, but to protect the open for some reason the tooth cavity. When you want to put a filling? Fillings required:

  • when damage to the tooth by caries;
  • in case of strong thinning of the enamel, causing inflammation of the pulp or nerve of the tooth;
  • the mechanical integrity of the tooth because of an injury;
  • at loss of old fillings.

Caries is an infectious disease of the teeth, the microorganisms cause destruction of the enamel due to excretion of acidic metabolites. When violated the integrity of the dental crown, begins the inflammatory process in the pulp, the nerve endings begin to send pain signals when temperature fluctuations or mechanical stress on the aching tooth. The cleansing of the cavity and coating with special material on top will help to stop inflammation and the spread of caries.

Severe damage to the enamel by acids or alkaline products is rare, but if it does happen, tooth cavity, as in the first case, becomes inflamed, and filling of root canals or the surface of the crown will help to restore the tooth.

When you wear old fillings or complete loss of the required pereplanirovka channels, because the open tooth cavity can become clogged with remnants of food or bacteria, leading to inflammation.

The types of seals

There are several types of fillings, which the dentist should inform the patient before installation, because they differ not only in cost but also in durability, density, «perseverance» on the spot. The most popular fillings are:

  • cement;
  • composite;
  • metal and ceramic.

About each is to talk separately, because they have their own drawbacks and advantages, as well as features to install and wear.

Cement fillings

This type of popcorn can be called a classic, because dental cement began to be used for a long time. There are three types of cement mixtures:

  • phosphate;
  • silicate;
  • steklovarenie.

Phosphate cement – the cheapest material for dental fillings and this affects the quality of the products. The seals are quite inexpensive but they will last considerably less in comparison with other compounds. Phosphate cement may crack, change color due to food coloring, but it practically does not communicate with the pulp of the tooth. If the patient needs to establish a coating of phosphate, but I want to increase its life, it will help in this admixture of silver.

Silicate fillings will cost a bit more expensive than the previous, but the expiration date is higher. Their feature is that they release fluoride ions, which inhibit secondary caries formation. This type of cement is recommended for people with carious destruction of the tooth, who have a limited budget. But this filling material has a significant drawback – it allocates phosphate acid, which irritates the pulp is healthy, so under the seal you will need a special gasket.

Steklovarenie cement appeared relatively recently, it costs more than their other «brothers», but is a budget version of the material for fillings. It is characterized by long service life, easy installation. Steklovarenie cement, as lime, to release fluoride ions inhibiting tooth decay. The only disadvantage of this material – colouring food dyes.

Composite fillings

Composite fillings the second generation, that is modern, belong to the middle price segment. They differ from the previous ones in that they have photosensitive elements in the composition, so once installed they are almost impossible to distinguish from tooth enamel. Moreover, composite materials are stronger and more durable, and safe root canal (the first generation of this category contained a toxic substance, but the second completely ruled them out).

There are two types of composite fillings:

  • light from Heliconia;
  • photopolymer.

First stiffen under the action of ultraviolet light, well-worn, practically does not differ in color from the enamel and do not stain food. Photopolymer filling of root canals is a great investment, because the procedure is not cheap, but this material almost does not wear out and does not fall out, not dark and prevents the formation of dental caries, its only drawback – the need for regular polishing once a year.

The first generation

Above it was a question about composite fillings the second generation. There is also the first generation of materials used for fillings informed. They were not as durable, less adjust the color of the enamel, but their main drawback – they are toxic to the patient and can worsen the condition of the healthy pulp of the tooth.

Composite materials of the first generation of cheap, but despite this, today they are rarely used, because the cement floor, for example, harms the body is much smaller, and costs about the same.

Metal and ceramic seals

Metal fillings are made of special alloy metals, they are heavy duty, they do not develop caries, but their main disadvantage is the unsightly appearance, because the shade they clearly differ from the other teeth. Sealing root canals with ceramics know-how in dentistry, which is now very popular, but to implement it is problematic because of the very high cost. Ceramic seal heavy-duty, durable, aesthetic, closes the gaps of any size, which can not afford the cement.

Method of sealing

The process of installation of the seal is not as simple as it might seem at first glance, especially if the patient is severely carious damage of tooth. The method of sealing consists of several stages:

  1. Fill the tooth is carefully cleaned when there is caries must be completely removed, because in the future this may lead to the development of infection under the filling.
  2. In the oral cavity of the patient set saliva ejector and around the tooth lay out cushions or latex pad to prevent the ingress of liquid to the working area.
  3. The treated tooth is applied special anti-microbial solution and then the acid liquid to carry out a thorough cleaning of the tooth from infection.
  4. In the tooth cavity is entered, adhesive a thin layer of flowable filling.
  5. Doctor preparing material for temporary fillings.
  6. After some time, put a permanent seal.

It is worth dwelling on the last two paragraphs, because they are key. Many do not understand why you need to put the temporary filling, because it is a waste of time and money. In this case, you should carefully read the following information.

Temporary and permanent fillings

After the tooth has been treated with antimicrobial and acidic drug, there is a small inflammation, especially if the channels and the root of the tooth was deeply affected by caries. If the infection was serious, on top of the previous tools apply a special anti-bacterial paste. On top of all of this necessarily establishes a temporary filling. Why? The inflammation must go down before the installation of permanent seal, but it may take from several days to one month, and since leaving the cured tooth in the open state is impossible, as after a few hours it will be full of bacteria and food. In this case, come to the aid of a temporary filling that protects the tooth cavity.


When the doctor finish to treat the tooth, the inflammation subsides, he can carry out root canal therapy with the use of more permanent material. If you set a permanent seal on the inflamed pulp, the risk of infection or pulpitis will be high. In this case, the patient runs the risk of spending even more money, because «unsuccessful» the seal will have to delete it and start over the whole process of installation.

Removal of the nerve

If the caries has reached the deeper layers of the pulp, it is necessary to remove it. In people, this procedure is called root canal, because the pulp contains many small blood vessels and nerve endings, that when the damage appears severe pain.

Method of filling root canals with the removal of the pulp is practically no different from the above described scheme, with the exception that in this case you should carefully monitor the complete filling of the canal root of a tooth, as in the formation of some voids there is a risk of infection and the appearance of cracks.


It’s clear how sealed the tooth, but what happens next? After installation-permanent – permanent seal it dry and start the finishing work.

  • First, to seal the tooth must be sanded, because the excess solidified material may hinder the person to chew and break his bite. To check the height of the seal the patient is given to eat parchment paper, which clearly shows the position of the teeth. This is followed by grinding with constant «fitting» on the parchment. At this stage it is important not to miss the moment when the seal will be normal height, because too low a position of the material also cause inconvenience.
  • Second, permanent seal requires polishing. This will help to smooth the surface of the filling material that will significantly reduce the risk of infection inside it and cracking. Also polishing the seal will improve its appearance, will further merge with the color of tooth enamel.

The pain after the sealing

After the installation of the temporary filling pain is likely to appear, because it takes time to eliminate the infection, to dampen the activity of nerve and reduce inflammation in the pulp. The nature of the discomfort is unbearable or aching.

When the tooth will be decorated with a permanent filling, the pain disturb the patient 3-5 days, they appear due to the fact that in the process of cleaning the tooth cavity, installation and polishing of fillings damaged gum tissue and pulp.

If since the installation of the permanent seal, it’s been a week and the pain continues to bother you – you need to go to the dentist. Usually the discomfort is not due to defective material, insufficient purification of the cavity of the tooth, an infection that was not killed before the end for other reasons. In this case, do not wait and regret the money spent, because over time the inflammation under seal will lead to chronic pulpitis, erosion of tooth and jaws (the latter happens extremely rarely).

Care after the sealing

After sealing it is necessary to observe simple rules which will help extend the shelf life of seals, as well as retain its appearance. First, it is necessary to limit the consumption of coffee and tea, because they can color filling material if without these drinks do not do – is to use a tube. Second, brushing must be a 2-3 times a day using a brush of medium hardness. Third, after each meal should rinse mouth with a special solution or plain water to particles of food remained on the seal.

Many seals, particularly cement, are not compatible with acids, so after sealing have been more careful with fruit juices, drink them without a straw. By eating citrus and apples you should definitely rinse your mouth with water, but it is not necessary to brush your teeth with a brush – the acid will quickly damage the surface of seals.

Dentists also recommend to completely abandon the sweet and starchy foods, but as practice shows, the majority of patients violate this rule, using chocolate and other sweets, but in moderation and they have no problems with the seal. Therefore, eat sweet and flour is possible, but it is necessary to follow a number between 20 and 30 grams chocolate 200 grams or muffin won’t hurt. After their use it is necessary to use the gum.

Fillings and root canal is one of the most important procedures in dentistry. The seal installation allows to save the tooth, restore it after the action of mechanical or chemical factors and to protect from recurrent carious lesions.

Methods of root canal filling and the tooth surface is different, because on the market today there are many different materials that will suit different budget. It is important to remember that this procedure requires special care, which will help extend the shelf life of the coating.
