About wisdom teeth: I personally suggest pulling them out. Because your wisdom teeth are not aligned with the jaw teeth, it is estimated that they will be elongated in the future, which may be bad for the temporomandibular joint. Moreover, wisdom teeth themselves do not bear any chewing force, and they are considered as a kind of abandoned degenerated organs, and often their positions are not very good. It is estimated that your teeth are decayed because you often plug things with your front teeth. This tooth is prone to problems, so it is better to pull it out as soon as possible.
About filling teeth: it is best to fill a small hole as soon as possible. A small hole will only grow bigger and bigger, and will not disappear automatically. After a long time, the small hole will become a big hole, and it is likely that the nerve will be reprocessed, and the treatment cost will be much higher. You know which is more cost-effective. If you want to delay when you are sick, it will only get worse.
