You probably expect your physician or pharmacist to ask about your medications. But when your dentist asks for an updated medication list, there’s a good reason. Prescription medications, over-the-counter (OTC) medicines, supplements, and certain medical treatments can affect the teeth, gums, saliva, and other tissues in the mouth. The American Dental Association (ADA) specifically recommends keeping your dentist informed about medications because they can affect both oral health and dental treatment.
From dry mouth and a higher risk of cavities to changes in your gums or even the way food tastes, here’s what to know about medications and oral health.
Dry Mouth Is One of the Most Common Medication-Related Oral Health Concerns
Saliva plays a key role in keeping your mouth healthy. It washes food and debris away from the teeth; helps to neutralize acids; protects soft and hard tissues; and supports chewing, swallowing, speaking, and taste.
Certain prescription and OTC medications can cause or worsen xerostomia, or dry mouth. The ADA lists antihistamines, antihypertensives, decongestants, pain medications, diuretics, muscle relaxants, some antidepressants, and GLP-1 receptor agonists among the medications that can contribute. Reduced salivary flow can also contribute to sensitivity and oral infections.
Why Dry Mouth Can Increase Your Risk of Cavities
If you’re suddenly developing cavities despite feeling like your brushing and flossing habits haven’t changed, dry mouth may be one factor worth discussing with your dentist. Less saliva means less natural protection against acids and food debris, which increases your risk of tooth decay and demineralization.
This issue is especially relevant in older adults. The ADA notes medication-related dry mouth as one reason some people experience renewed cavity risk later in life.
Some Medications Can Affect Your Gums, Too
Certain medications can cause gum tissue to enlarge, potentially making it more difficult to effectively clean around the teeth. Medication classes associated with gingival enlargement include some calcium-channel blockers, anticonvulsants, and immunosuppressants. The ADA specifically notes gingival hyperplasia as a potential effect of calcium-channel blockers used for hypertension.
Patients struggling with medication-induced gingival enlargement may notice:
- Gum tenderness
- Puffy or enlarged gums
- Areas that are harder to brush or floss
- Bleeding, particularly when inflamed
- Changes around the gum line
Medications Can Change How Your Mouth Feels or Even How Food Tastes
Medication-related changes in your mouth aren’t always limited to dry mouth or an increased risk of cavities. Some medications can affect how your mouth feels, how oral tissues look and function, and even how food tastes.
Because saliva plays an important role in taste, a significant reduction in salivary gland function can contribute to changes in taste. Some people may notice that foods taste different than usual, while others may experience an unpleasant, metallic, or otherwise altered taste, a condition known as dysgeusia.
Medication side effects can also contribute to burning or soreness in the mouth and changes to the tongue, lips, or other oral tissues. When dry mouth is involved, you may notice dry or cracked lips, a rough or uncomfortable tongue, or general irritation that makes eating and speaking less comfortable.
Certain medications can also make specific oral conditions more likely. Inhaled medications, for example, can contribute to oral candidiasis, commonly known as thrush. The ADA recommends rinsing your mouth after using an inhaler to help reduce this risk.
These symptoms may seem minor, but they’re worth mentioning to your dentist, especially if they are new, persistent, or began after starting or changing a medication. Your dentist can help identify possible contributing factors and recommend ways to make your mouth more comfortable.
Certain Medications Can Impact the Outcome of Your Dental Work
Beyond spotting side effects, your dentist needs an updated medication list to ensure that your body is primed for healing. More specifically, some medications may affect bleeding or saliva/oral tissues. Knowing your medications allows your dentist to make decisions around certain procedures and avoid potential medication interactions.
As an example, bisphosphonates and some other antiresorptive medications used for conditions including osteoporosis and cancer are associated with a rare but potentially serious condition called medication-related osteonecrosis of the jaw (MRONJ). Risk varies considerably depending on the medication, dose, duration, reason for treatment, and other factors. Your dentist needs to know what you’re taking so they can plan your care appropriately.
Five Things To Do If You Think a Medication Is Affecting Your Oral Health
- Don’t stop taking prescribed medication on your own. If you are experiencing side effects, talk to your prescribing healthcare professional before making any changes.
- Tell your dentist about all medications you’re taking, including prescription and OTC products. Be sure to update the list when something changes.
- Mention new oral symptoms, even if they seem minor. Issues to look out for include persistent dry mouth, new cavities, gum changes, sores, unusual tastes, and more.
- Ask for tips on how to manage your symptoms. For instance, if you’re struggling with dry mouth, you can drink water more frequently, chew sugar-free gum, and focus on incorporating fluoride into your dental care routine.
- Keep up with your preventative dental visits, especially if a medication is increasing your risk of tooth decay or gum problems.
