Maintaining good oral health is essential, but for many people, this can be a challenge, especially when taking certain medications. 

Let’s face it: most of us don’t think twice about the medications our doctor prescribes. But did you know that these medications meant to relieve discomfort or treat various health concerns can sometimes have unintended consequences? It’s frustrating, but understanding the issue can help protect your oral health.

In this blog post, we’ll understand why certain medications cause oral health issues and share some tips to keep your mouth healthy.

The Link Between Medications and Tooth Decay

Medicines can cause tooth decay in several ways. To understand this, let’s first look at how tooth decay develops.

The outer layer of your teeth, known as enamel, is protected by minerals that keep it strong and healthy. However, when enamel comes into contact with acids, it loses these important minerals. Acids are created when the bacteria in your mouth interact with the sugars and starches in the foods and drinks you consume.

If your teeth are frequently exposed to these acidic conditions, the enamel continues to break down, eventually giving rise to cavities. Some medications can create an environment in your mouth that is more conducive to this acid-based tooth decay. One common way is by causing dry mouth (aka Xerostomia), a side effect of certain drugs. When you have a dry mouth, you produce less saliva. 

Saliva is crucial for a healthy mouth, and often people aren’t aware of its significance. A typical human adult produces about half a liter to one liter of saliva per day. This saliva is primarily made up of water (99%) and a blend of proteins, electrolytes, and metabolic enzymes (1%). This is why, when people are anxious, they have a dry mouth. The salivary glands cease their functioning under stressful circumstances.

A recent study found that over 500 commonly recommended medicines mention dry mouth as a negative effect. This highlights how widespread this issue is, potentially impacting millions of Americans. Additionally, older adults are particularly vulnerable, with research indicating that over 30% of adults over 65 experience chronic dry mouth.

Saliva breaks down starches in your mouth, maintains a healthy pH balance, and also helps replenish the enamel with the proper minerals. The more saliva your mouth produces, the less acidic it will be. This leaves your teeth at a much greater risk of decay. 

Additionally, some liquid drugs also include sugar as an additive. This excess sugar in the mouth can also cause an increased growth of cavity-forming bacteria. By understanding how certain medications can disrupt the delicate balance in your mouth, you can take steps to protect your oral health and prevent unwanted tooth decay.

The Case of Suboxone: A Wake-up Call

Suboxone is a medication used to treat opioid dependence, but it has made headlines recently. A growing number of people using Suboxone have reported severe tooth decay, leading to the Suboxone lawsuit for teeth decay. As of April 2024, 44 lawsuits were pending in the US District Court for the Northern District of Ohio. 

According to TruLaw, these lawsuits will be consolidated and tried under the Multidistrict Litigation (MDL) number 3092. While investigations are ongoing, this case highlights the importance of being fully informed about any medication’s potential side effects, including those that might manifest over time.

Other Medications and Their Side Effects

While products like Suboxone can contribute to tooth decay, it’s important to note that other medications can also harm your oral health. Understanding these potential side effects is crucial for maintaining a healthy mouth, even when taking necessary medications.

One common issue is tooth discoloration. It is often caused by certain antibiotics that are used to treat conditions like asthma. Medications include tetracycline, the antibiotic ciprofloxacin (Cipro), and inhaled corticosteroids. These drugs can stain the teeth, leaving an unsightly appearance.

Another concerning side effect is gingival enlargement, or the overgrowth of gum tissue. This can be triggered by medications used to treat conditions like epilepsy (phenytoin), organ transplant rejection (cyclosporine), and high blood pressure (amlodipine). Gingival enlargement can lead to difficulties with eating and swelling and inflammation of the gums.

Medications that affect blood clotting, such as anticoagulants like warfarin (Coumadin) and NSAIDs like aspirin, can also increase the risk of gum bleeding. This can make oral hygiene practices more challenging and increase the chances of developing gum disease.

In rare cases, medications like oral bisphosphonates (for osteoporosis) and chemotherapy drugs can even cause a condition called osteonecrosis of the jaw. In this condition, a part of the jawbone begins to break down. While uncommon, it’s a serious side effect that requires close monitoring by professionals.

By being aware of these potential oral health complications associated with various medications, you can work closely with your dentist to implement strategies to protect your teeth and gums, even while undergoing necessary treatments.

Frequently Asked Questions

Q1. Are There Natural Remedies for Dry Mouth?

Yes! Try sugar-free gum and lozenges to stimulate saliva production. Sip water throughout the day. Always consult your dentist first to ensure these remedies are safe for you.

Q2. Can the Tooth Damage Caused by Suboxone Be Reversed?

The extent to which damage can be reversed depends on its severity. Minor decay may be treatable with fillings or crowns. However, in cases of severe decay or infection, tooth extraction might be necessary. Consulting your dentist early is crucial for the best possible outcome.

Q3. How Do I Maintain Good Oral Care While Taking These Medications?

If you’re medicating, discuss the potential oral health risks with your dentist. They can help you develop a plan to mitigate the negative effects and keep your mouth healthy.

First, start by maintaining a diligent oral hygiene routine. This involves cleaning your teeth twice a day, flossing every day, and using fluoride toothpaste. If you’re consuming medications that may potentially cause tooth decay, fluoride is your best friend. 

Drinking enough water can also improve saliva production. Moreover, it also helps cleanse food residue and harmful bacteria.

In addition, chewing sugar-free gum or sucking on sugar-free lozenges can improve saliva flow and relieve acids in the mouth. Regular dental check-ups and flossing are also crucial. Your dentist can monitor for any issues and catch problems early. In conclusion, understanding the potential impact of medications on oral health is crucial for maintaining a healthy smile. Remember, medication is vital, but so is your smile. By being mindful and cautious, you can work with your dentist to minimize side effects. Open communication and a commitment to good oral hygiene will help you keep your smile healthy for years.
