Medications That Affect Oral Health San Rafael, CA
It is important to consider the oral-systemic link and understand how medications you are taking can affect your oral health. When deciding whether or not to perform a procedure or prescribe medication, we take a couple of things into account. Though it is easy to think of the mouth as an isolated ecosystem, the medications you take to help regulate other body systems can play a role in your oral health.
To better understand this connection, our team at Kirby M. Yee DDS in San Rafael is here to help. Call us at (415) 223-2043 to learn more about our services or schedule an appointment.
Cancer Medications
Certain medications used as a part of cancer treatment could affect a patient's oral health. Many cancer medications, including chemotherapy, are notorious for causing symptoms such as dry mouth (xerostomia), mucositis (sores), and taste changes. A dry mouth, in particular, is an environment that is more vulnerable to the overgrowth of bacteria, which cause tooth decay, infections, or gum disease.
This is why a dentist needs to know if a patient is receiving cancer medicine. Patients who are experiencing oral side effects from cancer medications should inform their doctor and dentist. We may be able to help by prescribing a saliva substitute.

Behavior or Mood-Altering Drugs
Patients who are taking behavior or mood-altering medication may notice an impact on their oral health in more than one way. For instance, many medications that enhance mood can cause dry mouth (xerostomia) due to decreased saliva production. When we are producing a smaller amount of saliva, we become more vulnerable to developing conditions such as tooth decay or gum inflammation.
Some mood-altering medications can also cause side effects such as bruxism (tooth-grinding), which can negatively affect oral health. Additionally, many mood-altering drugs can cause fatigue or forgetfulness, which can create lapses in a person's dental care routine, particularly around bedtime hours. Patients who struggle with their oral health while taking medication for a mood-related condition should ask about how to manage side effects.

Medication for Diabetes
Diabetes can affect any area of the body, including the mouth. In both types of diabetes, Type I and Type II, elevated blood sugar can cause mouth symptoms such as dry mouth, taste changes, delayed wound healing, and increased inflammation and bleeding.
However, once a patient begins taking medication for diabetes, such as metformin or insulin, they may notice a positive impact on their oral health. When blood sugar is well-controlled with diabetes medications and a patient receives regular dental care, they can reduce the risk of developing oral conditions such as periodontal disease.

Regulation Medication
Cardiovascular
Certain regulatory medicines, including cardiovascular medications, cause gum enlargement, also known as gingival overgrowth. The enlargement is caused by inflammation of the gums from plaque build-up. According to Pharmacy Times, about a million North Americans are affected by drug-induced gingival overgrowth. Dentists can help cardiovascular patients limit their gum overgrowth to prevent further oral complications.
Thyroid
Patients with a thyroid imbalance often experience dry mouth syndrome, burning mouth syndrome, increased cavity development, enlarged tongue and gums, slow-healing mouth sores, delayed or rapid tooth growth, and osteoporosis. Thyroid medications alter the taste senses as well, which could limit a patient's nutritional intake. Drugs that balance hormone levels may increase incidences of mouth sores, tooth decay, and difficulty swallowing.

How to Keep Your Mouth Healthy While on Medication
For patients on a medication that affects their oral health, it is especially paramount that they follow disciplined dental hygiene measures. The American Dental Association recommends the following practices to maintain optimal oral health:
- Obtain regular, professional dental care
- Use a manual, powered, or ultrasonic toothbrush twice a day
- Use dental floss daily
For patients who are on cancer medication, in particular, the American Society of Clinical Oncology recommends the following additional tips:
- Gently brush twice daily, potentially using a soft child-sized brush or a soft brush that has been soaked in warm water.
- Avoid irritating foods and sugar intake to reduce the risk of infection or decay.
- Ensure they are getting an adequate supply of vitamin D and calcium to fortify the teeth and bones.

Frequently Asked Questions About Medications Linked to Dental Health
Q. What can I do to improve my oral health while taking psychotropic medications?
A. Once you are aware of the connection between your medications and your oral health, you can make changes to your routine that can positively impact your dental condition. According to the Oral Health Foundation, changes as simple as reducing your sugar intake, and brushing with fluoride toothpaste, can help mitigate the impact of your medications.
Q. What kinds of heart medications can cause changes in my gum tissue?
A. The most common cardiovascular medication that contributes to gum changes is known as a calcium channel blocker. Examples of calcium channel blockers include verapamil, amlodipine, and nifedipine. If you are noticing changes in your gums from a medication, your dentist may be able to discuss an alternative medication with your physician.
Q. What types of medications affect oral health?
A. Many different types of medications affect the oral cavity. It also largely depends on the form and dosage. Among them are antihistamines, decongestants, painkillers, high blood pressure medications, muscle relaxants, drugs for urinary incontinence, Parkinson's disease medications, and antidepressants.
Q. What can my dentist do if I am taking a medicine that affects my oral health?
A. A dentist considers your oral-systemic connection when conducting assessments of your oral health. If you are taking a medication that affects your oral health, your dentist may be the first healthcare professional to identify this. If we do so, we will collaborate with your prescribing physician to make necessary changes or adjustments. We can also consider medications, such as saliva substitutes, to help with symptoms.
Q. Does the dentist work with primary care doctors to alter medications?
A. Patients who require treatment may need to alter their medications in order to undergo the procedure. We can communicate with your doctor to suggest certain medications that are safer or measures to take until you recover from the procedure. We can also work with you on questions to ask your doctor about oral medications.
