There is much misinformation about the idea of taking antibiotics for bad breath.  Some assume that since most cases of bad breath are caused by germs, bacteria, and infection then it's of course a good idea to try antibiotics.  But before you talk to your doctor about such a prescription, there are some things that you need to consider.

Things To Consider Before Taking Antibiotics
The first is that antibiotics are something that you take only for a short period of time, either to fix an infection or to fight one off.  Thinking that antibiotics for bad breath are a permanent cure is just not accurate.  They are only a short-term solution to fight a temporary condition you may have at the moment.

Another consideration when it comes to antibiotics for bad breath is that not all cases of halitosis are caused by infections but by surface germs and bacteria.  Very often this is because of poor oral hygiene.  If you fail to brush and floss regularly and properly, food particles remain in the mouth and start to decay, bringing about these bacteria and the germs that are causing bad breath.  In cases such as this, antibiotics for bad breath will be ineffective because there is no real infection that is causing the halitosis.

It's also true that an overuse of antibiotics is very bad for a person.  Germs can build up their resistance to such medications so that when you have a real infection that requires antibiotics, you will not respond so readily to the medicine.  Using antibiotics for bad breath helps the germs and bacteria in your body build up that resistance.  In the long run, you can be doing harm to your body and your system by misusing antibiotics in this way.  When you really need them, they're ineffective.

Consult Your Doctor
Of course, only your doctor can know for sure if antibiotics for bad breath are necessary in your case.  If your halitosis is caused by an infection in your mouth or the throat, then they may be necessary.  The antibiotics are treating the infection that's causing your bad breath, and not just the bad breath itself. 

If your doctor does prescribe antibiotics for bad breath for you, be sure you're following the dosage instructions carefully and are aware of the symptoms of an allergic reaction.  And don't stop taking the medicines until your doctor says that it's fine for you to do so.
