Accurately determine how many channels in the tooth, it is possible only with the help of an x-ray. Of course, their number depends on the location. For example, the teeth in the back of the jaw have the greatest chewing load. Therefore, they require a stronger restraint system. They themselves are much larger than other teeth, have more roots and canals. However, this indicator is not constant. It does not mean that the upper and lower incisors will have only one channel. In this matter, it all depends on the individual characteristics of the human jaw system. How many channels in the tooth require filling, the dentist must determine when opening the tooth or by x-ray.
How is a tooth made?
If you do not delve deeply into this issue, the structure of the teeth may seem quite simple. Above the gum is the so-called crown, and under it are the roots. Their number depends on the degree of pressure on the tooth. The larger it is, the more powerful its retention system is. Therefore, it is easy to understand how many channels there are in a tooth with a high chewing load potential. Their number is much larger than that of representatives of the "biting" group.
The root itself is covered with enamel, and dentin is located under it. The hole where the base of the tooth is located is called the alveoli. Between them there is a tiny distance represented by connective tissue - periodontium. Nerve bundles and blood vessels are located here.
There is a cavity inside each tooth. It contains the pulp - this is an accumulation of nerves and blood vessels. They are responsible for the continuous nutrition of bone formations. If removed, the tooth will become dead. Towards the roots, the cavity narrows slightly. This is the dental canal. It stretches from the top of the root to its very base.
Percentage ratio
As already noted, the body of each person is individual. Therefore, to determine how many channels in a tooth a healthy individual should have, there are no clear rules. Information on this issue in dentistry is not given in numerical but in percentage terms.
The number of channels in the tooth of different jaws
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. In the lower jaw, the situation with these teeth is somewhat different. It can be represented in the following percentage ratio:
- The first incisor usually has one channel (70% of cases). Only every third patient has 2.
- The second tooth in equal percentage may 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, and only in 6% of cases there are two.
Premolars are characterized by a larger structure, they are subjected to a stronger load. It can be assumed that the number of channels in them also increases exponentially. However, here it is not so simple.
How many channels in the 4th tooth? Such a number is usually designated the first premolar. In the upper jaw, only 9% of the 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 tooth. How many channels does he have? This tooth has even greater pressure. However, this does not affect the number of channels. Only 1% of their number is three.
On the lower jaw, the situation is different. The first, as well as the second premolar, are generally not three-channel. In 74% of cases, the four and 89% of the five have only one branch.
Molar teeth are considered larger teeth. Therefore, the number of channels they are rightly increasing. Sixes on the upper jaw can have either three or all four branches. The probability in this case is approximately the same. It is extremely rare in the lower jaw that the picture changes. Usually there are as many canals in the upper teeth, as many in the lower teeth.
The posterior molars are characterized by the following percentage:
- Upper Seven: 30% to 70% four and three channels respectively.
- Lower seven: 77% to 13% three and two branches.
Rear molars are not very different in structure. Therefore, any dentist can almost 100% correctly say how many channels in a tooth 7th in a given person.
Talk about the tooth of wisdom
A wisdom tooth is a very unique phenomenon that does not fall under statistics. The top one can have from one to five channels, and the bottom one has three. Often, during the autopsy treatment, additional branches are found. Therefore, it is very difficult to say exactly how many channels in the lower teeth of wisdom.
They also differ in their irregular shape. It is rarely possible to meet a direct channel without a narrow passage. This feature significantly complicates the treatment process.
Erroneous opinion
A tooth, as you know, consists of roots and a subcortical part. Often there is an erroneous opinion that how many canals in molars, the same number of roots. This is not at all true. Branches quite often diverge and even bifurcate next to the pulp. Moreover, several channels can pass simultaneously in one root almost parallel to each other.
Given the listed features of the structure of the teeth, dentists need to carefully approach the treatment procedure. 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 save those teeth that just 10 years ago had to be removed due to the inability to treat. Root canal therapy is a rather complicated procedure. Branches are located next to the pulp. It is represented by many blood vessels and nerve bundles. Any wrong decision by the dentist can lead to death of the tooth. Today, a separate section of dentistry - endodontics - deals with root canal treatment.
The most common form of pathology in which the patient is forced to seek help from specialists in this field is the inflammatory process. Lack of timely treatment can result in soft tissue damage within the canal. Most often, various ailments such as caries lead to the pathological process. However, appropriate treatment may be needed with periodontitis.
Dental Disease Prevention
So that any pathologies associated with the teeth are bypassed, it is necessary to monitor the hygiene of the oral cavity.
- Dentists do not recommend cleaning immediately after eating. Better to wait 20-30 minutes.
- In order to avoid the accumulation of pathogenic microbes, you need to use special rinsing agents. If there is no way to purchase a finished product, you can make it at home. For this, ordinary chamomile tea or a decoction on oak bark is suitable.
- Teeth should be brushed no more than 2 times a day, since the enamel tends to thin out gradually.
These simple recommendations help to avoid dental diseases. However, do not forget that the dentist should be visited twice a year.
Conclusion
Now you know the features of the structure of the teeth and can imagine the procedure for their treatment. If someone suddenly wonders how many channels are in the 6th tooth, such a question will not baffle you. The information presented in this article is useful to everyone.
