رائحة الفم الكريهة



 
 
يعاني ملايين البشر حول العالم من رائحة الفم الكريهة, وهي مشكلة تحمل كثيرين على تجنب المحادثات القريبة وتسبب إحباطاً للبعض لاسيما الذين يحرصون على الحفاظ على أسنان صحية ونظيفة. لكن كثيرين يجهلون أن رائحة الفم سببها الرئيس صحة اللسان وليس الأسنان.

ورائحة الفم الكريهة في أغلب الأحيان لا يلاحظها الشخص نفسه لأن الدماغ يتأقلم مع رائحة الفرد الشخصية. لكن هناك طرقاً للتشخيص الذاتي, أولها اختبار اللسان، من خلال تحديد لونه.

فإذا كان وردياً ولامعاً, فذلك يشير إلى نفس جيد، أما إذا كان اللسان أبيض ومتقشراً يشير إلى رائحة فم كريهة. ويتم الاختبار الثاني يكون بلعق الجزء الخلفي من اليد، وتركها تجف لبضع ثوان، ثم يقوم الشخص بشم رائحة المكان ذاته.

ورائحة الفم الكريهة ليست عادة دليلاً على صحة الأسنان. فصحة اللسان تلعب الدور الأبرز في هذه المشكلة علماً بأن معدل أنواع البكتيريا في فم الإنسان تناهز الـ600.

ويعتبر جفاف الفم أهم أسباب تكاثر البكتيريا عليه. لأن اللعاب فيه أوكسجين وهو ما يجعله العدو الطبيعي للبكتيريا كريهة الرائحة التي لا يمكنها العيش بوجوده.

ومن الممكن أن يتم التغلب على المشكلة عبر شرب الماء وحتى مضغ العلكة الخالية من السكر ما سينتج اللعاب بشكل طبيعي. كما يمكن أيضاً استخدام حبوب النعناع الخالية من السكر أو غسول الفم. ولكن هذه الحلول مؤقتة تحجب الرائحة لكنها لا تقتل البكتيريا.

كما يحتوي الشاي الأخضر على خصائص تتيح التغلب على مشكلة رائحة الفم، لكون تلك الخصائص مضادة للبكتيريا ويمكن إضافة قليل من القرفة إليه ففيها زيوت أساسية تقتل عدداً من أنواع بكتيريا الفم.

وينصح الأطباء أخيراً بتناول الفاكهة والخضراوات لاحتوائها على فوائد إيجابية ومزدوجة، ففضلاً عن غناها بمواد تكافح رائحة الفم الكريهة, ينتج مضغ المزيد منها كمية أكبر من اللعاب

Bad breath (Halitosis)

Bad Breath.

Bad Breath

More than 70% of teens say bad breath is an instant turnoff. About 85% believe it's the most important thing to avoid when meeting someone for the first time. And while bad breath can be treated and avoided, you often don't even know that you have it!
Bad breath (called halitosis) is a common problem not only for teens, but also for everyone. So what exactly is it, what causes it, and, most importantly, how can you get rid of it?

What Causes Bad Breath?
Bad breath has a variety of causes, including:
  • Bacterial infections
  • Medications and medical conditions
  • Post-nasal drip
  • Poor hygiene (yep, you have to brush teeth more frequently)
In most cases, bad breath comes from the gums and tongue. Some bacteria in your mouth may produce compounds that result in an odor.
Certain foods, like garlic and onions, not only leave lasting odors in your mouth, but are also absorbed into the bloodstream. The odors are then expelled from the lungs. Until these foods are eliminated from the body, mouthwash, chewing gum, and toothpaste can only mask the odors on the breath.
For some people, a dry mouth causes bad breath. Dry mouth can result from taking antihistamines for allergies or a cold, or from antidepressants. It can also result from localized infections, diabetes, gastrointestinal disturbances, or liver or kidney ailments.
The post-nasal drip that streams down the back of your throat during colds, allergies, or sinus infections can result in bad breath. Sometimes, tiny food nuggets lodge in the crypts of your tonsils or on the tongue and cause a foul odor.
But most bad breath is the result of poor oral hygiene. Basically, that means you don't brush or floss frequently enough. How many times have you heard that from your dentist?
Bacteria that build up on the back of your tongue or in between your teeth are the main culprits. Certain types of bacteria love to breed on the tongue, in the crevices between your teeth, or in untreated cavities.
Finally -- yet most important -- tobacco products cause bad breath. If you smoke tobacco or chew smokeless tobacco, ask you dentist or your primary health care professional for tips on kicking the habit.
How Can I Tell If I Have Bad Breath?
Believe it or not, the most common method doesn't work to diagnose your own bad breath. Many teens think that they can blow into their hands and smell their breath. That simply doesn't work.
Instead, do this. Lick the back of your hand, let the saliva dry, then take a whiff. What you smell there is your true breath.
Another good way? If you have a trusted friend, ask them to smell your breath. Parents can also tell you if you ask.
How Do I Control My Bad Breath?
Here are some tips for controlling bad breath.
  • Practice good oral hygiene. Brush and floss after every meal, or at least twice a day. Proper brushing also involves brushing your tongue, cheeks, and the roof of your mouth to remove bacteria and food particles. Flossing removes bacteria, plaque, and food particles that may be trapped between teeth. Many dentists and dental hygienists also recommend cleaning your tongue with a tongue scraper, a plastic tool that scrapes away bacteria that builds up on the tongue. Mouthwashes and rinses can also temporarily relieve bad breath.
  • Remember your retainer. If you wear a retainer or have some kind of removable appliance, clean it thoroughly each time you brush. If you have braces, take extra time and care to clean all the nooks and crannies. Your orthodontist is a good source of information about keeping your braces clean.
  • Chew sugar-free gum. Chewing sugar-free gum helps stimulate saliva. This helps cleanse the teeth and gums and prevents dry mouth.
  • Stop using tobacco. Get help and kick the habit.
  • Use an anti-bacterial mouthwash. Gargling once or twice a day is good for teeth and gums and kills bad-breath bacteria in your mouth.
Where Does My Dentist Fit In?
While there is no dental specialty that deals just with bad breath, your family dentist should be able to address your concerns about oral hygiene.
If your dentist determines that your mouth is healthy, he or she may refer you to a general physician or a specialist to determine the cause of your bad breath. Your doctor can tell you if you are taking medications that can cause dry mouth, or if you have other medical conditions that may make you more likely to have dry mouth and bad breath.
Seeing your dentist regularly (at least every six months) and following his or her advice will reduce or eliminate any bad breath problems you may have. Then you won't have to worry about those potential "close encounters."
