Dentist 's  Response
Most probable cause of bad breath including burning rubber smell is caused by improper oral hygiene and bad habits like tobacco chewing,smoking, alcohol intake, lots of intake of intense smelled food like garlic,onion,fish..etc.. being majority caused by deposits on teeth so he may undergo cleaning/oral prophylaxis by dentist.. (even some times third molar eruption/impaction can be the cause in 20-30yr age group despite of proper hygiene too..) and if then also his smell doesnt go he can go to gastroenterologist who will try to locate any other abdominal origin of the smell..
regarding smoking and chewing tobacco, stoppage of such habits then followed by cleaning will resolve problem completely.. tell him to use mouthwash after every meals and increase his water/fluid intake meanwhile to reduce the intensity of smell..

hi...
thanks for the query...
bad breath can be due to oral, ENT or medical problems...
visit your dentist for complete oral examination... sometime, grossly carious tooth is the source of foul smell... in that case it will require restorations...
or due to presence of plaque and calculus... and inflamed gums and deep pockets... in that case it will require proper scaling and root planing...

brushing twice daily with pea sized tooth paste will help... make sure that you brush your teeth AFTER MEALS instead of before meals... rinse after every meal... also use tongue cleaners... tongue may harbor micro organisms on its surface and can be the source of bad breath...

if still persists, consult general physician to rule out any metabolic disease... consult ENT specialist also...

hope it will help you...
take care...

Hello,
Thanks for writing to us.
There are many factors like:-
diabetes, poor oral hygiene or any that you have eaten.
try scraping your tongue after eating or drinking anything. Before talking to someone, have a sip of cold water then swish it around your mouth a few seconds. It helps!
Start keeping a diary of what you eat and drink each day and how you smell that day. The rubber smell might not be related to what you just ate, it could be what you ate up to a few days ago so that's why you don't see an obvious pattern. Keeping a food diary will help establish a pattern with foods you ate several days earlier.
Hope this helps you.
Wishing you good health...
Regards.

Hello,

Thanks for posting your query.
From what you are describing I feel that your boyfriend has bad breath or halitosis. Bad breath can be caused due to many causes ranging from systemic diseases like diabetes, not drinking enough water, periodontal infections, sinusitis/ tonsillitis which causes a person to breathe from mouth,even certain food cause it. Having too many decayed teeth can also be a factor.
I would advise your boyfriend to go to a dentist . If there are no dental findings, visit to an ENT would be helpful.

Hello and thank you for your question:
Burning rubber is a new one for me. Everyone has a different opinion on smells so I may conclude that it smells like something else. A few things I can think of
-Diabetes or atkins diet (low carb high protein) can lead to acetone breath which is very strong
-gingivitis/periodontits which to me smells like rotten raw chicken
-Coffee/tobacco that can have a pungeant smell
-tonsiliths (hard mineral deposites in the tonsils) these have a very strong odor
-a diet high in garlic, cumen, curry, onions tend to give off a strong odor

Most likely it's due to poor oral hygiene and needs to be addressed.

A lot of bacteria that causes halitosis or bad breath is on the top surface of the tongue. Have him brush his tongue in a back to forward fashion. Floss, brush and rinse with mouth wash daily. If the odor persists, suggest an evaluation with ENT for tonsiliths and to have diabetes ruled out with internal medicine.

Hope this helps.
Best regards and good health

Hello
Welcome to HCM
I went through your problem & would like to inform you that its gingivitis.I would like to tell you few common reasons for foul odor:-
-improper oral hygiene
-dry mouth or xerostomia
-gastric problem
-hormonal imbalance
-alcohol intake
Most common reason is improper oral hygiene.How many times you brush is not as important as how you brush.You hold your brush with 45 degree angulation to your teeth and give gentle strokes.
Change your brush every 3 months. Start using 0.2%chlorhexidine mouthwash once daily half an hour after brushing.Ask him to quit all bad habits for better results.
Also go for oral prophylaxis once every 6 months & start intake of citrous fruits.
Take Care

I support Dr Amit Sharma's response. But one more point, a badly decayed tooth can also lead to such fetid odor in the mouth. Get his oral examination done. When the anaerobic bacterial flora in the oral cavity (which doesn't require oxygen to live) becomes very populous, it leads to extremely foul smell in the mouth. After complete oral prophylaxis, and treatment of any decayed tooth, ask him to use chlorhexidine gluconate based mouth wash, twice daily. To have a pleasant mouth odor, he should: 1) Brush his teeth twice daily in a correct method as described by dentist, 2) Rinse rigorously after every meal, and each snacks he consume, its advisable to use your finger to clean your teeth and gums while you rinse, as it helps to remove sticky items like chocolates, sweets, biscuits etc, which are not removed with plain squishing of water in your mouth. 3) Ask him to clean his tongue daily, which harbors bacterias that cause foul breath & taste.

The only reason I can think of is smoking or chewing tobacco. Few of the cigars and local brands usually emit foul odour. If these are not the case of contention. Then you should simply go in for a gastric exam where endoscopy might help. But before all this his oral hygiene needs to be questioned. The right choice would be a cleaning with a dentist, a decent mouthwash then if it persists you need professional help.

Hello,
Improper cleaning of dental work as well as teeth can cause nasty smells in your mouth. suggest him for teeth cleaned, and FLOSS after brush & after eating food. Keep tongue cleaned as well.If he do that and STILL have a bad smell, he might have medical problem that can be diagnosed by your dentist or doctor.
thanks, take care

Dentist, Implantology Dr. S.Naveen Kumar's  Response
Hi Jeni,
Bad Breath (halitosis)caused by sulphur-producing bacteria that live within the surface of the tongue and in the throat which releases volatile sulphur
compounds .

Major causes are:
Periodontitis or poor oral hygiene,dry mouth & Smoking

Less causes include:
1.Acid and bile reflux from the stomach
2.chronic sinusitis
3.Kidney failure, various carcinomas, metabolic dysfunctions, and biochemical disorders.
4.Foods - such as onions, garlic or cauliflower, which induce certain odours.

Treatment for bad breath can vary, depending on the cause. If your bad breath is thought to be caused by an underlying health condition, your dentist will likely refer you to your physician.

To reduce bad breath, help avoid cavities and lower your risk of gum disease, consistently practice good oral hygiene.

Regards,
dr.naveen
