Specifically, a prosthodontist works with fixing issues that have to do with tooth loss or jaw problems. You would see a prosthodontist if you needed dentures or were having a prosthetic tooth inserted into a spot where you lost a tooth. Prosthodontists deal with both the appearance and the function of your teeth and gums. Along with fixing dental problems so that you have a functional bite, prosthodontists also work to ensure that your teeth look natural and attractive. If you have any extensive dental surgery, a prosthodontist will help you.
