Why You Should Correct Double Teeth
Double teeth are due to the unevenness of the teeth compared to those with well aligned teeth,I have difficulty brushing my teeth and my bite is unbalanced.
Therefore, in addition to appearance, there is a high risk of tooth decay and gum disease due to poor dental cleaning, as well as stress on other teeth due to a poor bite, all of which can lead to problems that affect the life of the teeth.
Improvement of double teeth has the following advantages
- Lower risk of tooth decay, gum disease, and bad breath
- Reduced load on other teeth due to biting
- Improvement of mouth breathing
- It's going to look good.
If you are wondering whether you should correct your double teeth, it would be more beneficial to do so from the standpoint of tooth longevity and oral health, in addition to appearance.
Lower risk of tooth decay, gum disease, and bad breath
Double teeth may protrude more than the adjacent teeth or grow above the gums. Therefore,Stains that cause cavities, gum disease, and bad breath tend to accumulate between and at the base of teeth.
When double teeth are corrected by orthodontics, the unevenness of the tooth line is reduced, making it easier to care for and prevent stains from accumulating,As a result, the risk of cavities, gum disease, and bad breath is lowered.
Reduced load on other teeth due to biting
Teeth are responsible for distributing and receiving the force exerted on them when we chew food or grind our teeth. The canine teeth, in particular, have long roots and can take more chewing force than the other teeth.
In the case of double teeth, the cuspid teeth do not bite together and the bite force cannot be released to the cuspid teeth, which increases the load on the other teeth.
If there is a large amount of continuous dental stress, the teeth are more likely to crack in the future, or the nerves of the teeth may be damaged and die.
He said he would improve the double teeth,The canine teeth bite into each other and distribute the load on the teeth, thus extending the life of the teeth.
Improvement of mouth breathing
If the canine teeth are in the way and the lips cannot close properly, the mouth is left open, resulting in mouth breathing.
Nasal breathing, in which humans normally breathe with their mouths closed, is desirable, and the filtering function of the nose prevents viruses and bacteria from entering the body.
However, mouth breathing allows viruses and bacteria to enter the body directly through the mouth, which can lead to a weakened immune system and cause illness and allergies.
Mouth breathing also causes dry mouth due to dryness of the mouth. Dry mouth increases the risk of tooth decay, gum disease, and bad breath because the antibacterial action of saliva and the self-cleansing action of saliva to wash away stains on the teeth do not work.
Improvement of the double teeth allows the mouth to close, which improves the body's immune system and oral function.
It's going to look good.
Because the unevenness of the double tooth is gone and the teeth line up,The mouth looks beautiful when smiling.
In the case of severe double teeth, the protrusion of the mouth may be reduced and the profile and facial lines may appear cleaner when the teeth are aligned.
Causes of double teeth
Double teeth are caused by insufficient space for teeth to grow due to the following reasons
- Large teeth.
- Excess teeth are present.
- The location of the canine teeth in the jaw has shifted where they can be
Because it is not possible to prevent it by oneself,Orthodontic treatment is necessary to correct double teeth.
If the jaws are underdeveloped due to heredity or some other factor, there is not enough space for the canine teeth to grow because the jaws are too small.It will be.
Canine teeth are relatively the last teeth to erupt during the eruption process. Therefore, if the jaw is small, the space is filled by the permanent teeth that come in first, and the last canine tooth to erupt has nowhere to go, resulting in a double tooth.
He said the teeth are large compared to the size of the jaw,As in the case of small jaws, there is insufficient space for the canine teeth to grow in and they tend to become double teeth.
Excess teeth are present.
Excess teeth are those that are extra than the normal number of permanent teeth (32 including wisdom teeth).
The extra teeth will grow in, and inevitably there will be insufficient space for the canine teeth to grow in, resulting in a double tooth.
Excess teeth may also not erupt. In this case, they may interfere with the eruption of permanent teeth in the bone, causing dental irregularities other than double teeth.
The position of the canine teeth in the jaw has shifted.
Canine teeth are produced in the jaw from about 5.5 to 6 months of age, taking about 12 to 15 years to erupt.
Therefore,During the process of growth, the size of the jaw and the influence of other teeth may shift the position of the canine teeth, resulting in a double tooth.
How to Correct Double Teeth
The most common way to fix a double tooth is to either pull the tooth or to shave a little space between the teeth to make the tooth smaller to make room for the double tooth to line up.
Orthodontic appliances are used to improve double teeth by moving the teeth while allowing space for the double teeth to line up. There are two main types of orthodontic appliances.
- mouthpiece orthodontics
- wire orthodontia
Each device has different features and specialties in moving teeth, so it is advisable to consult with your dentist, taking into consideration your double tooth condition, the features of the device, and your lifestyle.
This orthodontic method uses a transparent, smooth-surfaced mouthpiece to move the teeth.
There are several manufacturers of mouthpiece orthodontics, some specializing in partial orthodontics and others with nearly as much range of indications as wire orthodontics.
- The device is transparent and almost invisible
- Can be removed by yourself, so you can eat and brush your teeth almost as usual.
- Less painful than wire braces
- No metal is used, so people with metal allergies can be treated.
- Good at moving back teeth backward, so may be able to improve double teeth in a non-extraction manner.
The following are some of the features of this system. In addition, the way the teeth are moved can be simulated in 3D before treatment, so the double tooth can be treated efficiently.
- Partial orthodontic treatment focusing on front teeth → about 100,000-700,000 yen
- Total orthodontic correction including back teeth → about 800,000-1,000,000 yen
- Partial orthodontic treatment focusing on the front teeth → about 5 months to 1 year and 6 months
- Total orthodontic correction including back teeth → about 1 to 2 years
The cost and length of treatment depends on the dentist's pricing and the condition of the double tooth.
However,In the case of mouthpiece orthodontics, the pre-treatment simulation shows the exact treatment period and cost, making it easier to predict treatment prospects.
Wire braces are,This orthodontic method involves attaching square devices called brackets and shape-memory wires to the teeth to move them.
- Long history of orthodontic treatment and can improve mild to severe double teeth
- Suitable for improving double teeth with a large amount of tooth movement, involving extractions and osteotomies.
The following are some of the characteristicsSevere double teeth or double teeth with skeletal problems in the bite will often be recommended for wire braces.
There is a wide variety of materials for wires and brackets, including metal devices and white ceramic devices that blend in with the teeth and are less noticeable.
There are two types of braces: front braces, in which the wires are worn on the front of the teeth, and back braces, in which the wires are worn on the back of the teeth. If you do not want the appliance to stand out, we recommend the backside braces, where the wires are placed on the backs of the teeth.
- Surface orthodontics → about 600,000-1,000,000 yen
- Backside orthodontics → about 1,000,000-1,500,000 yen
- Surface orthodontics → about 1 to 3 years
- Backside orthodontics → about 1-3 years
For wire braces, the cost depends on the type of wire used and the position where the wire is placed, in addition to the condition of the double tooth.
The least expensive type of wire orthodontics is the frontal orthodontic treatment using metal wires.The cost tends to be higher when white, less noticeable wires are chosen for front side braces.
The most expensive is backside braces.Unlike front braces, which can use off-the-shelf wires, custom-made devices worn on the backs of complexly shaped teeth are more costly.
If you want to fix a double tooth, you need a reliable dentist.
Orthodontic treatment of double teeth not only improves the mouth and makes the teeth look better when smiling, but also extends the life of the teeth by reducing the risk of tooth decay, gum disease, and bad breath.
Double teeth can be treated with orthodontic treatment using a mouthpiece or wire to move the teeth.
