"We have identified that 247 patients were treated by this dentist. Of these, we are unable to find addresses for 14, almost certainly because they no longer live in Dumfries and Galloway.
"If you were seen at a Sunday emergency dental clinic at Nithbank between April 2004 and April 2007 and have not yet received a letter, it is unlikely that you were treated by the dentist in question.
"Nevertheless, if you are concerned that you may have been missed off the list please contact the helpline."
Around 250 dental patients in Dumfries have been warned of a 'slight risk' that they may have been exposed to HIV, after a former dentist who treated them was found to have the disease.
The former dentist, who has not been named to protect patient confidentiality, treated people in Dumfries over a three year period.
The dentist provided locum Sunday emergency cover at Nithbank Hospital between April 2004 and 2007.
Patients in the NHS Dumfries and Galloway area have been warned as a precaution of "a very slight risk that they might have been exposed to the virus".
