Canine teeth are also called thread cutting teeth, it is the third tooth counted from the middle of the front teeth and it is clear that it has a pointed shape.

 

In Japan, it has been said that it is lovely, calling "irregular teeth alignment disordered" as "tooth teeth". However, in recent years Western values ​​have expanded, and it has come to be said that the well-aligned teeth are beautiful.

 

Not only for beauty but also for the health of the whole body it is important to align the teeth.

 

In the first part, we will introduce the role of the canine tooth and the diseases caused by the eight teeth.

 

 

 

1: What is the role of canine teeth?

 

 

 

1-1: Canine teeth are actually very important!

 

 

 

To clean the front teeth biting food, the back teeth to grind food ... So what is the role of the cuspid teeth? To eat it? That's not all!

 

Actually, the cuspid teeth have a role to "protect the back teeth"!

 

Human back teeth are strong for the application of vertical force, but weak against left and right forces. However, in order to grind food with back teeth, you must move the chin left and right by all means. When moving the jaws left and right, only the cuspid teeth engage, preventing the right and left forces from being transmitted directly to the back teeth!

 

 

 

1-2: The cuspid teeth are very solid

 

 

 

The cuspid teeth are made very sturdy. The root of the tooth is longer than other teeth, and it is tightly buried in the bone of the jaw.

 

 

 

1-3: Canine teeth become standard of correction

 

 

 

Looking at the alignment of teeth, I draw "U character". A place where the curve of the front teeth turns into a straight line across the back teeth. That is a cuspid. By deciding the correct position of the cuspid teeth, you will decide the position of the upper and lower teeth.

 

 

 

2: Why can a cuspid teeth be double tooth?

 

 

 

2-1: Jaw bone is small

 

 

 

If the bone of the jaw is small relative to the permanent tooth, the alignment of the teeth becomes easy to be disturbed.

 

The size of the bone of the jaw is greatly affected by heredity, but dietary life from the time of childhood also has an influence. In modern times, it is hard to chew hard food so it is difficult to grow big jaws.

 

 

 

2-2: It is slow for canine teeth to grow

 

 

 

The cuspid teeth are too slow to come inside permanent teeth, so they are easily extruded into other permanent teeth that have come before, making them easy to become double teeth.

 

 

 

3: Yae teeth cause disease!

 

Correct it in such a case!

 

 

 

3-1: Caries and periodontal disease

 

 

 

In addition to problems of appearance, double tooth causes disease.

 

First of all, it is tooth decay and periodontal disease.

 

It is difficult to clean with tooth brushing if the tooth alignment is disturbed. Then, not only the cuspid teeth, which are eight tooth teeth, but also the neighboring teeth are liable to repeatedly become tooth decay many times.

 

Periodontal disease is a disease in which a lumpy bacteria mass "plaque (also called plaque)" adheres to the teeth, dissolves the bones of the jaw, and the teeth are loose or the teeth come off at the end. Again this is a disease caused by the shortage of cleaning of teeth.

 

 

 

3-2: mouth breathing ~ bad breath · tooth decay · cause of a cold!

 

 

 

If the alignment of teeth is disturbed, you may not be able to close your mouth naturally and you may end up getting mouth breathing on a daily basis. If the mouth dries, the bactericidal action of saliva will not work. Then it causes bad breath, a decayed tooth, it becomes easy to catch a cold by drying throat!

 

 

 

 

 

In the second part, we will introduce about merit and demerit of correction.
