hello. Director Kim Hyun-soon no see.
Orthodontics is not simply a procedure to straighten teeth.
Tooth movement is a process in which various factors such as the alveolar bone (gum bone), muscles, tongue position, and habits interact in a complex manner.
that How long the correction will take It is difficult to explain this solely based on the type of device or the hospital's capabilities.
In fact, even when using similar orthodontic devices One and a half years People who end in ten minutes more than 2 years There are people who get caught.
One of the important factors that makes that difference is precisely lifestyle habits no see.
Today, it can prolong the orthodontic treatment period and, in some cases, affect the treatment results. lifestyle habits Let's take a closer look at this.
1. The habit of breathing through the mouth
We are basically designed to breathe through our noses.
However, nasal breathing becomes difficult due to rhinitis, allergies, or decreased oral muscle function. If the habit of breathing through your mouth becomes ingrained, it can affect the alignment of your teeth.
Especially if mouth breathing persists from childhood, The growth direction of the facial skeleton itself changes, and the maxilla narrows. malocclusion The risk of it leading to increases.
For adults Even so, oral pressure imbalances can occur, which may delay tooth movement during orthodontic treatment.
✔️ Reasons that hinder tooth movement
- - The tongue drops downward, pushing the teeth outward.
- - Weakness in lip strength causes the front teeth to protrude or separate.
- - Occlusal problems occur as the growth balance of the upper and lower jaws is disrupted.
✔️ Improvement Method
- - Press your tongue against the roof of your mouth, lightly close your lips, and slightly separate your teeth.
- - Problems that obstruct breathing, such as rhinitis and tonsil hypertrophy, should be treated in conjunction with ENT care.
- - Consistently practice MFT (Myofunctional Therapy)
✔️ Super Simple MFT Practice
- - Pucker your lips 10 times
- - Inhale through the nose and exhale quietly.
- - Pronounce 'h' 10 times with your tongue pressed against the roof of your mouth
→ Repeat 3 sets a day, make it a habit for morning, noon, and evening
2. The habit of clenching teeth
unconsciously The habit of clenching teeth It is a lifestyle habit that many people have without realizing it.
In particular, you often tense your jaw when you are stressed, concentrating, or sleeping.
This habit is jaw joint pain, tooth wear, periodontal tissue damage It can cause, and if you are undergoing correction Inhibits tooth movement This becomes a major cause.
✔️ Reasons that hinder tooth movement
- - Continuous vertical pressure is transmitted to the correction device, reducing movement force
-
- A force acting in the opposite direction to the correction direction delays the correction time
-
- Increased risk of tooth root resorption during orthodontic treatment
✔️ Reasons that hinder tooth movement
- - Use of occlusal adjustment devices to avoid molar contact
-
- Self-awareness training to prevent unconscious bad habits
-
- Concurrent Botox treatment for jaw muscle relaxation if necessary
※ If the habit of clenching teeth is severe, the period of wearing the retainer after correction may be prolonged, so habit correction is necessary in advance.
3. If you want to enhance the effectiveness of treatment, start with your lifestyle habits.
Orthodontics is not simply about attaching devices to the teeth. It is a treatment based on physiological changes that move the teeth.
thus daily lifestyle habits This can have a direct impact on the success of the correction.
for example,
✅ position of the tongue If it is not done properly, the front teeth may separate again.
✅ mouth breathing If you continue this, your face shape will change, and
✅ teeth-grinding habit If this is present, tooth movement does not occur properly, delaying treatment.
| Lifestyle habits items | Desirable habits |
|---|---|
| breathing method | Nasal breathing, quietly inhaling and exhaling through the nose |
| position of the tongue | Position the tip of the tongue so that it touches the roof of the mouth behind the upper teeth. |
| Lip posture | Lightly close your lips and keep them closed without excessive force. |
| jaw strength | Keep your jaw relaxed and avoid bringing your teeth together. |
| Sleeping position | Sleep on your back, without lying on your side or stomach. |
| Eating habits | Chewing using both sides evenly |
What is just as important as the dental procedure is How I live no see.
Changing small habits effort With just this, the treatment period can be shortened and the results can be maintained more stably.
To maintain healthy teeth and function for a long time, try practicing this starting today. 😁
