A dentist in Portland, Oregon is suing one of his former patients for writing a negative review on a popular website.

Dr. Mo Saleh filed suit after Spencer Bailey wrote about his experience at Dental Dynamics on Yelp.com, DoctorOogle.com, and Google.

Dr. Saleh claimed that the posts damaged his reputation, caused profit loss, and emotional distress.

Bailey wrote that the care he received was "improper and insufficient" and urged others to "GET A SECOND OPINION" if informed of the existence of caries by Dr. Saleh.

Saleh's attorney, Jennifer Gates, says the review posted online contained false information and therefore is not speech that is protected by the United States Constitution or Oregon law.

She seeks 300-thousand dollars for her client.

Bailey's lawyers contend that after Bailey went to Dr. Saleh, he went to another dentist who found unnecessary and poorly placed fillings.

The attorneys also claim that Dr. Saleh made threatening phone calls to Bailey, demanding that he remove the online comments.

Bailey complied, but Dr. Saleh moved forward with his lawsuit.

Dentists who have tried to combat negative comments posted online have often been unsuccessful.

In 2011, a California dentist who filed a defamation case over negative reviews on Yelp.com had to pay $80,000 in attorney fees to a young patient's parents, whom she sued.

Do you think the dentist has a case? Is it defamation or freedom of speech?
