Toothache can really be very annoying. In fact, sometimes it is considered more agonizing than childbirth. Compounding the problem, many of these pains do not have a quick fix for anything. Analgesics, with or without prescription, can eliminate some of the pain but is sure to return in a few days or even hours. Antibiotics are quite successful treatment for pain, but sometimes it may take several days before they feel some relief. When it comes to permanent treatments for most toothaches, antibiotics are usually the best choice.


The most famous and preferred for treating toothaches that result from a dental infection antibiotic penicillin, which has been used in dentistry since World War II. Derived from a type of mold, there are several side effects associated with the use of penicillin, with only a few reports of nausea, vomiting, diarrhea and black hairy tongue. These symptoms usually end after the patient stops taking penicillin. It is also important to realize that some types of infections have been developed, either partially or completely resistant to penicillin. In these cases, treatment with penicillin is useless.


Amoxicillin, a modified version of penicillin, was developed for the treatment of infections and penicillin-resistant bacteria. This is the antibiotic most often used in dentistry today, is also used in patients who are allergic to penicillin and is often prescribed to those who have never taken an antibiotic. However, there are more side effects associated with the use of Amoxicillin with penicillin; the most common are nausea, vomiting, diarrhea, black hairy tongue, rash, jaundice, stained teeth, hyperactivity, agitation and insomnia. Overdosing can cause kidney failure, crystalluria and interstitial nephritis.


Used less frequently than penicillin and amoxicillin, clindamycin is used to treat infections that are the direct result of penicillin-resistant bacteria and amoxicillin. However, there are many side effects that are reported in this antibiotic consumers, some of which can be very severe; these are: nausea, vomiting, diarrhea, abdominal pain, pseudomembranous colitis, dermatitis and leukopenia. Clindamycin overdose can cause seizures and depression.
