10 Causes of Mouth Ulcers
Cause #8: Syphilis
Syphilis is a sexually transmitted infection that is caused by the bacterium Treponema pallidum. The signs and symptoms of syphilis depend on the stage of infection. In the primary stage, there can be multiple sores and chancres that are painless, firm, and non-itchy. In the secondary stage, there can be a diffuse rash along with sores or ulcers in the mouth or genitals.
Latent syphilis has little to no symptoms, while tertiary syphilis can lead to neurological and cardiovascular symptoms. Syphilis can be diagnosed through blood tests and treated with antibiotics such as benzathine benzylpenicillin, doxycycline, and tetracycline.
