What's the difference between periodontist and a regular dentist, and would you be able to find one who takes self pay?

Simple: Periodontists specialize in gum diseases, generally not hard to find a dentist that takes cash check or charge.

Yes: Any dentist/periodontist should be wiling to accept self pay. A periodontist specializes/limits their practice to treatment of the gums/jaw bone after having received an extra 2-3 years of training.

See below: A general dentist is trained in all areas of dental treatment. A peridontist specializes in treatment of diseases of the gums and supporting tissues of the teeth. Your general dentist can handle many gum problems, but if your needs are extensive or unique, he/she may refer you to a periodontist for more advanced treatment options. Self pay? Do you mean payment plans? Call around to see.

A specialist: A periodontist is dentist who specializes in the diagnosis and treatment of gum diseases and the placement of dental implants. In addition to their dental degrees, periodontists have an additional 2-3 years of training specifically in their field.
