If your baby has white bumps on the gums, there are several possibilities. 1. the common name of horse teeth, you can choose to wait for them to fall out on their own, or remove them if necessary. 2. as the new teeth are erupting, they will show the normal shape of the teeth when they are fully erupted, so just wait for them to erupt on their own, no treatment is needed. 3. due to the inflammation of the root tip of the tooth to produce pus, you can do root canal treatment, drilling the tooth to remove the nerve, local flushing and sealing. The nerve is removed and the tooth is rinsed and sealed locally. If necessary, oral anti-inflammatory drugs are given to promote inflammation, and after the inflammation has subsided, the white bumps on the gums will naturally subside. The tooth can be closed and then chewed normally, or in the case of a baby tooth, a pre-crowned restoration can be done.
