Cephalexin and Toothaches

Cephalexin, an antibiotic, is often used to treat bacterial infections--including tooth abscess. Dentists prescribe Cephalexin for an infected tooth or an abscessed tooth, which are very painful and may become very serious if left untreated.

What Is An Abscessed Tooth?

• An abscessed tooth is a severe infection in one or more teeth. The most common cause of an abscessed tooth is decay, when left untreated it becomes infected with bacteria. Abscess can be very painful, causing sharp pains and aches, making it almost impossible to eat at times.

Medication Used to Treat a Tooth Infection

• Once the tooth becomes abscessed, a dentist may prescribe Cephalexin to aid in fighting infection against the bacteria that has invaded the structure in or around the tooth. It is imperative that you follow all of your dentist's orders and take the complete prescription.

How Cephalexin Works

• Cephalexin will help your body's defense system fight off the infection from your tooth. Before and during antibiotic treatment, you may experience swelling and pus but it should subside as you follow along with your medication.

How To Use Cephalexin

• Take all prescribed medication until it is completely gone. Do not take the medication for longer than prescribed as this may cause your body to build resistance against the medication. This is very important so that the infection does not come back. Your dentist will prescribe the medication according to your weight, gender and size. Should you miss a dose, take the missed dose as soon as you remember. If it's time for your next dose, do not take the missed dose. Instead, take the next regularly scheduled dose and continue taking until the medication is gone.

Side Effects Of Cephalexin

• The most common side effect of Cephalexin is diarrhea. You should not take a medication to treat the diarrhea unless directed by your caregiver. Other side effects include sore throat, dry mouth, feeling tired, pale or yellow skin and fever.
