How Can Medications Affect Your Oral Health? What Patients in Dubbo Should Know
When we think about the side effects of medications, we often consider nausea, fatigue or dizziness. But what many patients don’t realise is that the medications they take every day can also significantly affect their oral health. From dry mouth and enamel erosion to gum overgrowth and oral infections, the impact can be far-reaching – especially if you’re not aware of the risks. If you live in Dubbo and take regular medications, understanding their effects on your teeth and gums is an essential step in preserving your long-term dental wellbeing.
What Types of Medications Commonly Affect Oral Health?
Several everyday prescription and over-the-counter medications can influence the health of your mouth. The following types are particularly known for their oral health side effects:
Antihistamines: Often used for allergies, they can cause significant dry mouth (xerostomia).
Antidepressants: These may suppress salivary gland function and increase gum sensitivity.
Blood pressure medications: Especially calcium channel blockers, which are associated with gum overgrowth.
Chemotherapy drugs: Known to cause mouth ulcers, mucositis, and increase susceptibility to infections.
Painkillers and opioids: These may reduce saliva flow and alter pain response in the mouth.
Asthma inhalers: Can lead to fungal infections like oral thrush due to changes in oral flora.
Immunosuppressants: Often prescribed after organ transplants or for autoimmune conditions, they can increase gum inflammation and infection risk.
Diuretics: May contribute to dry mouth and change the pH balance of the oral cavity.
How Does Dry Mouth Impact Your Teeth and Gums?
Dry mouth, or xerostomia, is one of the most common medication-related side effects. Saliva plays a crucial role in maintaining oral health by neutralising acids, washing away food particles, and providing disease-fighting substances.
When saliva production is reduced, the following issues can arise:
Increased risk of tooth decay
Bad breath
Oral thrush (fungal infections)
Gum irritation
Difficulty chewing or swallowing
According to the Australian Dental Association, patients taking multiple medications, especially older adults, are at higher risk of developing dry mouth due to cumulative side effects.
What Are Some Visible Signs That Medications Are Affecting Your Mouth?
If you take regular medication, watch for these warning signs in your oral cavity:
Persistent dry or sticky feeling in the mouth
Burning sensations or changes in taste
Red, inflamed or swollen gums
Excessive plaque build-up despite regular brushing
Sores, ulcers or fungal infections
Delayed healing after dental treatments
These symptoms can develop gradually, making them easy to overlook. Regular dental check-ups help ensure any issues are caught early.
Can Certain Medications Cause Gum Overgrowth?
Yes, some medications can cause an overgrowth of gum tissue, known as gingival hyperplasia. This is particularly common with:
Calcium channel blockers (e.g. for hypertension)
Anticonvulsants
Immunosuppressants
This overgrowth can make brushing and flossing more difficult, increasing the risk of gingivitis and periodontal disease if not managed appropriately.
What Are the Hidden Risks of Medication on Your Jaw and Bones?
Long-term use of bisphosphonates or similar medications for osteoporosis may increase the risk of a rare but serious condition called medication-related osteonecrosis of the jaw (MRONJ). This condition affects the bone's ability to heal after injury or dental extractions.
Signs may include:
Pain, swelling or infection in the jaw
Loose teeth
Poor healing of gums
This highlights the importance of informing your Emergency dentist of all the medications you are taking.
How Can You Minimise the Oral Side Effects of Medications?
There are several proactive steps patients in Dubbo can take to protect their oral health while taking essential medications:
Stay hydrated throughout the day
Brush twice daily with a fluoride toothpaste
Use fluoride mouthrinses if recommended by your dentist
Avoid mouthwashes containing alcohol
Chew sugar-free gum to stimulate saliva
Attend regular dental check-ups and cleanings
Inform your dentist of any medication changes
Ask your GP or pharmacist if sugar-free alternatives are available
