Xray showed one of my teeth has infection. might rinsing with salt water solution draw out this infection?

No: Dental infections require physical removal of infected tooth material by root canal treatment or extraction, often under the protection of antibiotic coverage, sometimes with incision and drainage. Chance of successful cure by salt water rinse alone = 0%. Please see your Dentist and follow his/her professional advice to the letter. Treatment of infection is not a DIY project.

No.: An infection caused by a tooth is usually called an abscess.This a pocket of infection(pus?) that is in your jawbone.Rinsing with salt water will not reach the area.You may need a root canal or an extraction,

Um, no: You need to have your dentist treat the infection by treating the tooth. Root canal therapy or extraction appear to be your options... salt water rinsing will do nothing for this infection. If it were that easy there would be no need for dental care.

Dental Infections: Dental infections require specific treatment by a qualified dentist. The cause of the infection needs to be determined and the proper treatment rendered. Antibiotics are also required to prevent spread of infection. Unfortunately nothing you do yourself at home will have any significant effect or reducing or eliminating the infection. Left untreated these infections get worse. See a dentist now.

No, see any DDS: to drain the dental abscess. If not treated, a serious dental abscess can eventually kill. The infection may spread to your jaw, cheeks, sinus and to other areas of your head and neck. The antibiotics or rinsing with salt water will give you only a temporary relief. See any dentist for examination, x-rays and treatment.
