How many canals in the tooth of the upper and lower jaws?

It is possible to determine exactly how many channels are in the tooth, using only an X-ray. Of course, their number depends on the location. For example, the teeth in the back of the jaw have the greatest masticatory load. Therefore, they need a stronger restraint system. They themselves are much larger than other teeth, they have more roots and canals. However, this indicator is not permanent. It does not mean that the upper and lower incisors have only one channel. In this issue, everything depends on the individual characteristics of the jaw system of man. How many channels in the tooth require a filling, the dentist should determine when opening the tooth or by means of an X-ray.

How is the tooth arranged?

If you do not go deep into this question, the structure of your teeth may seem quite simple. Above the gum there is a so-called crown, and under it - the roots. Their number depends on the degree of pressure on the tooth. The more it is, the more its holding system is more powerful. Therefore, it is easy to understand how many channels in the tooth with a high potential of chewing load. Their number is much larger than that of representatives of the "biting" group.

The root itself is covered with enamel, and under it is located dentin. The well, where the base of the tooth is located, is called the alveolus. Between them there is a tiny distance, represented by a connective tissue, - periodontium. Here there are nerve bundles and blood vessels.

Inside each tooth there is a cavity. It contains pulp - a collection of nerves and blood vessels. They are responsible for the continuous feeding of bone formations. If it is removed, the tooth will become dead. Towards the roots, the cavity narrows slightly. This is the tooth canal. It stretches from the top of the root to its very base.

Percentage

As already noted, the body of each person is individual. Therefore, to determine how many channels in the tooth should be in a healthy individual, there are no clear rules. Information on this issue in dentistry is given not in numerical, but in percentage terms.

Number of canals in the tooth of different jaws

The doctors initially start from the fact that the same teeth on both jaws are significantly different. The first three upper incisors usually have one channel. On the lower jaw, the situation with these teeth is somewhat different. It can be represented in the following percentages:

• In the first incisor there is usually one channel (70% of cases). Only every third patient has 2.
• The second tooth in an equal percentage can have one or two channels (56% to 44%).
• On the lower jaw, the third incisor requires special attention. Almost always it has a single channel, but only in 6% of cases there are two.

The premolars are characterized by a larger structure, they are more heavily loaded. It can be assumed that the number of channels in them also increases in geometric progression. However, even here everything is not so simple.

How many channels are in the tooth of the 4th? This figure usually indicates the first premolar. On the upper jaw, only 9% of teeth have a single canal. In 6% of cases, their number may increase to three. The rest are usually found with two branches. The next premolar is 5 teeth. How many channels does he have? This tooth has even greater pressure. However, this does not affect the number of channels. Only 1% of them are three.

On the lower jaw, the situation is different. The first, as well as the second premolars are not generally three-channel. In 74% of cases, the four and 89% of the five have only one branch.

Molars are considered larger teeth. Therefore, the number of channels in them is fairly increased. Sixes on the upper jaw can have as three, and all four branches. The probability in this case is approximately the same. Very rarely the picture changes on the lower jaw. Usually how many channels in the upper teeth, as much in the lower ones.

The posterior molars are characterized by the following percentages:

• Upper Seven: 30% to 70% four and three channels respectively.
• Lower Seven: 77% to 13% three and two branches.

The posterior molars do not differ much in their structure. Therefore, any dentist can almost 100% correctly say how many channels in the tooth 7th of this or that person.

Let's talk about wisdom tooth

The wisdom tooth is a very unique phenomenon that does not fall under the statistics. The top can have from one to five channels, and at the bottom this number is three. Often during the treatment at autopsy, additional branches are found. Therefore, it is very difficult to say exactly how many channels in the lower wisdom teeth.

They also differ in their irregular shape. It is rare to find a straight channel without a narrow stroke. This feature significantly complicates the process of treatment.

Wrong opinion

The tooth, as is known, consists of roots and a subcoronal part. Often there is an erroneous opinion that how many channels in the molars, as much as the roots. This is not so. Branches quite often diverge and even bifurcate next to the pulp. Moreover, in one root, several channels can pass simultaneously in parallel to each other.

Given the above features of the structure of the teeth, dentists need to carefully approach the procedure of treatment. If the doctor misses one of the channels, the therapy will have to be repeated after a while.

Root Canal Treatment

The development of modern dentistry increasingly allows you to keep those teeth that were literally 10 years ago needed to be removed because of the impossibility of treatment. Root canal therapy is a rather complicated procedure. Branches are located next to the pulp. It is represented by a multitude of blood vessels and neural bundles. Any wrong decision by the dentist can lead to the death of the tooth. Today, a separate section of dentistry - endodontics - is engaged in the treatment of root canals.

The most common form of pathology, in which the patient is forced to seek help from specialists in this field, is the inflammatory process. The lack of timely treatment can result in the defeat of soft tissues within the canal. Most often, the pathological process leads to various ailments such as caries. However, appropriate treatment may be needed and with periodontitis.

Measures to prevent dental diseases

That any pathologies associated with the teeth, bypassed, it is necessary to monitor the oral hygiene.

1. Dentists do not recommend cleaning after eating. It is better to wait 20-30 minutes.
2. To avoid the accumulation of pathogens, you need to use special rinses. If there is no opportunity to purchase a finished product, you can make it at home. This is suitable for ordinary chamomile tea or a decoction on the bark of oak.
3. Brush your teeth no more than 2 times a day, as the enamel has the property to gradually thin out.

Such simple recommendations can avoid dental diseases. However, do not forget that the dentist should be visited twice a year.

Conclusion

Now you know the peculiarities of the structure of the teeth and can imagine the procedure for their treatment. If someone suddenly inquires about how many channels are in the tooth of the 6th, such a question will not put you at a deadlock. The information presented in this article is useful for everyone.
