Can the last two molar tooth together be removed and replaced? - Bottom right. They are crowned and haven't seen dentist yet.

More info. depends on the situation you will need an evaluation and xrays by a dentist to determine your alternate treatments. Implants work well in the lower jaw if there is sufficient bone.
Yes. Yes, they can be removed if they are indicated to be removed but I wouldn't necessarily replace both of them unless they were definitely needed for full function or support. Generally I would restore the first molar first. Please see a dentist to eval area.
