If it is not a deciduous tooth, it is generally a genetic problem. Being born feels a bit ugly like a mouse tooth, but it generally has no effect on health, no matter what it is.

However, if you don't think it looks good, you can usually make a tooth veneer. I just made porcelain veneers, only two. I didn't know until I went to see a doctor that many people would have such small teeth, which is quite common. Let me show you the effect. This is a comparison chart of my teeth sent by Director Lu Yuanfeng at that time. This comparison is very obvious and natural. Porcelain veneer looks much more normal now.

It is also said on the internet that porcelain teeth are made, but porcelain teeth should be ground once, or porcelain teeth have little effect on teeth.
