A 36-year-old female asked:

if allergic to penicillan can i take keflex for a tooth abscess?

Dr. Theodore Davantzis

Keflex: Keflex is a cephalosporin antibiotic and is not normally prescribed for dental infections. Since an antibiotic will not resolve your dental issues, your best bet is to see a local dentist and have the tooth evaluated.

Penicillin Allergy: If you are allergic to Penicillin there is a 10% chance you will be allergic to Keflex. I often use this antibiotic as an alternative to Penicillin. However this needs to be discussed with the doctor who knows your complete medical history and is personally treating you as there are other alternatives also available!
Dr. Robert Douglas
Orthodontics 51 years experience
Keflex : is an excellent antibiotic but there's a one in ten chance that you are also allergic to it. Your dentist will decide the appropriate medication. In the meanwhile you should have the tooth treated to eliminate the source of infection as no antibiotic will cure it.
Dr. Corey Clay
Allergy and Immunology 10 years experience
Alternative?: Depends on the type of allergy. If the history is consistent with an immune mechanism, then an alternative should be used if available. Then, once improved, an Allergist can perform penicillin skin testing to see if the allergy is still present so that in the future, if it is not, options will not be limited. The test takes 40 minutes and most patients are found to no longer have allergy.
Dr. Arnold Malerman
Orthodontics 53 years experience
Don't self medicate: Antibiotics do not cure Dentel abscesses. Meds reduce severity and spread of infection, but specific Dental Treatment (root canal/crown or extraction/implant/crown) required for "cure." If tooth not properly treated infection will come roaring back when meds discontinued. Inform Dentist of your Penicillin allergy. Numerous appropriate alternatives are available.

A member asked:

Is it true that fluoride can cause tooth discoloration in children?

8 doctor answers22 doctors weighed in
Dr. Michael Coogan
Pediatrics 48 years experience
Yes: Fluoride, which occurs naturally in some city water supplies, is incorporated into children's developing teeth and helps to prevent tooth decay. Many municipalities have carefully added Fluoride to their water. Unfortunately, too much Fluoride may cause discoloration of the enamel. You should speak to your pedodontist or pediatrician about the proper amount of Fluoride for your child.
Dr. Andrew Killgore
Cosmetic Dentistry 16 years experience
The potential systemic health consequences to our pediatric population far outweigh the benefits of strengthening enamel and caries prevention. I have attached a brief Harvard overview to reference one of many potential concerns. http://www.hsph.harvard.edu/news/features/fluoride-childrens-health-grandjean-choi/

Dr. Anthony D'Amico

In addition there can be potential consequences to the adult population. Some areas have naturally ocurring very heavy concentrations of fluoride in their water and flourosis or dark discoloration is common in these localities. I am a dentist but have never been in favor of medicating a total population to treat one segment-especially when they can receive the benefits of flouride in other ways.

I agree to some extent with Drs. D'Amico & Coogan, but want to add that injested (drops, pills, drinks high in fluoride, swallowed toothpaste) is difficult to control dosage that could lead to discoloration of developing adult teeth for a specific child. Discolored baby teeth is usually caused from something injested or illness of mother during pregnancy. See: http://www.888-smile.com/Ask_Dr.html

Can keflex cause colitis or swelling of the intestines?

Yes: Virtually every antibiotic has the potential to cause a type of colitis called c. Difficile colitis. Antibiotics kill bacteria. Even as normal people we have thousands of different kinds of bacteria in our colons. When you take antibiotics, it kills some, which allows other types to thrive. When clostridium difficile thrives, it causes colitis. This can be life-threatening and require surgery.
