Q: I have allergies. Should I be aware of any possible dental implications?
A: Allergies can have an impact on your dental health, particularly if you take antihistamines for relief. Just as they help dry up your sinuses, so too can they contribute to dryness in the mouth. Anything that reduces the flow of saliva can render you less able to naturally wash away food particles. That, in turn, can lead to a buildup of plaque and a problem with cavities.
As with any medication you take for any condition, advise your dentist if you take an antihistamine for allergies. Your dentist may recommend that you increase your intake of water, or that you suck on sugar-free candy to keep your mouth moist. Another concern is that if you are allergic to one substance, say pollen, you may be allergic to other things. That could include drugs that your dentist may normally prescribe, such as penicillin, for an ailment or an infection. Allergic reactions can be as mild as itchy eyes and a runny nose. However, allergic reactions can also be more serious. You should always inform your dentist about your general health and especially about any allergies.
