First of all, we need to understand this question: why do we need to correct our teeth? It seems that your writing is because the doctor thinks that your upper teeth are protruding and your lower teeth are not aligned properly, which needs to be corrected. However, you don't think it will affect your image or your life. You have to listen to your doctor if you are sick, but it is a little cosmetic surgery to make your teeth more beautiful through orthodontics (if it is only uneven, it is not serious enough to affect your function). So this requires your subjective consciousness, do you want to be more perfect? This is very important.

Let me answer your other questions.

1, because of crowded teeth, uneven tooth arrangement and protrusion, it is generally necessary to extract teeth. Extracting teeth and killing nerves are two completely different things. It won't be too painful to extract teeth under local anesthesia. After tooth extraction, the fossa will slowly heal and grow back to the bone. (2 ~ 3 months)

2. The teeth are moving in the process of correction, and this slow movement invisible to the naked eye is the principle of correction-alveolar bone reconstruction. This is more professional, but the action is certain.

3. Age is not a problem, but it will affect the correction effect and increase the difficulty of correction. For example, when you are old, you will feel sore and the treatment time will be longer.

4. Money is not a problem. There are domestic systems and imported systems ranging from 4,000 to 20,000 yuan.

5. Normal treatment has no terrible sequelae.

6. Now that the technology is very mature, the cost of orthodontics has not increased much in the past 10 years (relative to the current price), which is relatively cheap and will never decrease, which is certain.

In addition, I suggest you choose a good doctor with experience or regular study to correct it. Because the so-called sequelae are actually caused by unreasonable treatment.

Finally, I wish you a happy and smooth treatment!
