Thank you for responding. I visit my dentist every 6 months. I just had my check up last friday. My dentist said there's nothing in my mouth that could be causing this problem. He said my teeth are perfect, no decay, no gum infections -nothing. The only thing he mention that could be causing my breath problems from mouth is that I stress a lot and have a dry mouth but he could not say anything about the nose odour and why all the sudden I started to suffer from it. I have seen ENT doctor 2 weeks ago and like I said before he believes it is h.pylori and he did say acid reflux. I am really hoping that this will sort out at least the nose odour as you can imagine how depressing my life at the moment is. Thank you again.
You may want to consult with the people who wrote this article or ask your doctors to do so.
This, in addition to my initial response, from the journal, Gastroesophageal reflux, dental erosion, and halitosis in epidemiological surveys: a systematic review
European Journal of Gastroenterology & Hepatology
Issue: Volume 25(2), February 2013, p 135–141
In published studies, it has been suggested that dental wear is associated with gastroesophageal reflux disease (GERD). This systematic review was carried out to evaluate the association of GERD, dental erosion, and halitosis and to compare the indices adopted in epidemiological surveys. The Medline database (until October, 2011) was searched systematically to identify studies evaluating the prevalence of oral alterations, such as dental erosion and halitosis, in patients with GERD symptoms. Two reviewers analyzed all reports and the selected studies were evaluated according to the quality of evidence, using the validated Newcastle–Ottawa Quality Assessment Scale. Full-text copies of a total of 32 publications were obtained in duplicate. Sixteen publications were identified among the citations in the Bibliographic lists of studies that fulfilled the exclusion/inclusion criteria and quality of evidence. The relationship between dental erosion and GERD patients was significant in only seven studies. According to three studies, halitosis could be one of several extraesophageal symptoms or manifestations in GERD patients. In one study, it was found that the mucosa of GERD patients was significantly more acidic in comparison with that of the control group. This systematic review showed that there is a relationship between GERD and oral diseases (dental erosion and halitosis). The epidemiological surveys used different indices to analyze GERD and dental erosion. Further research could investigate the best method for assessing the two diseases.
A condition called phantosmia and is not uncommon. The following explanation is from the Mayo Clinic: “ “Many people are sensitive to certain smells, but in an olfactory hallucination (phantosmia), you detect smells that aren't really present in your environment. The odors detected in phantosmia vary from person to person and may be foul or pleasant. They can occur in one or both nostrils and usually can't be masked by food.”
That your friends “do smell something”, however, is a very different circumstance. When the odor is apparent to others, nine out of ten cases have an oral cause and so the initial evaluation should be by your dentist. Occasionally, in this circumstance the problem may arise from the gastrointestinal tract, such as with acid reflux (and perhaps a secondary effect of this reflux on oral structures, including the gums). In rare instances, other parts of the intestines may be involved and the source of the odor otherwise uncommon bacteria, such as you suggest.
Your best bet would be to start with your dentist and then, if another opinion is desired, with an ENT Specialist with an interest in unpleasant nasal/oral odors. You can find such a person by going to this site and clicking on Rhinology. http://www.entnet.org/findanentmore.cfm
Good luck.
