For tooth ankylosis, what would you do to the tooth if there are no symptoms?

I will leave it as long as there’s no symptom. When a tooth is ankylosed, it means that it is fused together with the bone. So unless it’s giving issues I would leave it alone. The only consideration is that if ankylosed teeth are cracked or require a root canal, eventually if the root canal fails you will need to remove the tooth. It is very difficult to extract ankylosed teeth because the tooth and the bone is fused together. The extraction is very difficult and 99% of the time it’s got to be surgery to remove the tooth.
