GLP-1 Medications & Your Oral Health

What patients taking Ozempic®, Wegovy®, Zepbound®, or Mounjaro® should know.

GLP-1 medications have become increasingly popular for managing diabetes and supporting weight loss. While these medications offer many health benefits, they may also affect your oral health in ways you may not expect.

Potential Oral Health Changes
💧 Dry Mouth
• Reduced saliva can increase the risk of cavities, plaque buildup, gum disease, and bad breath.
🤢 Acid Reflux or Vomiting
• Frequent exposure to stomach acid can weaken tooth enamel and increase sensitivity.
🥗 Changes in Diet & Nutrition
• Eating less or making significant dietary changes may affect the nutrients needed to support healthy teeth and gums.
🦷 Increased Risk of Gum Irritation
• Dry mouth and dietary changes may contribute to inflammation and plaque accumulation.

Protect Your Smile
✔ Stay hydrated throughout the day.
✔ Brush twice daily with fluoride toothpaste.
✔ Floss every day.
✔ If vomiting occurs, rinse with water first and wait approximately 30 minutes before brushing.
✔ Maintain regular dental hygiene appointments.
✔ Keep your dental team informed of any medication changes.

Why We Ask About Your Medications

Many patients are surprised when we ask about medication changes at each visit. Your medications can affect far more than your overall health—they can also impact your oral health.

Whether you’re taking a GLP-1 medication or any other prescription medication, it’s important that your dental team stays informed. Certain medications may contribute to dry mouth, changes in appetite, acid reflux, altered healing, or other side effects that can affect your teeth and gums.

Keeping your medication list up to date helps us:
• Identify potential risk factors early
• Recommend personalized preventive care
• Monitor changes in your oral health
• Provide the safest and most effective treatment possible

🦷 Medication Spotlight: GLP-1 Medications
Taking Ozempic®, Wegovy®, Zepbound®, or Mounjaro®? Tell us!

Keeping your medication list updated helps us provide the best care possible and monitor for any oral health changes that may occur. Your mouth is connected to your overall health, and the more we know, the better we can care for you.

We are committed to helping you achieve a healthy smile and a healthy body.

🌸 May This Spring Bring You Better Sleep… Not More Mouth Breathing

Spring is here—but along with flowers and sunshine often comes allergy season, congestion, snoring, and mouth breathing.

Did you know the way you breathe while you sleep can affect your teeth, gums, energy levels, and overall health?

Many people deal with mouth breathing, snoring, or sleep apnea without realizing how much it impacts their body. Waking up tired, dry-mouthed, foggy, or with headaches is often a clue that sleep isn’t as restorative as it should be.

😮‍💨 How Mouth Breathing Affects Your Mouth

Your nose is designed to filter, humidify, and warm the air you breathe. When breathing shifts to the mouth during sleep, several problems can happen:

🦷 Dry Mouth = Higher Risk for Decay

Saliva helps protect teeth by neutralizing acids and washing away bacteria. When your mouth dries out overnight:

- pH becomes more acidic
- Cavity-causing bacteria thrive
- Plaque builds faster
- Bad breath increases
- Tooth decay risk rises

😬Gum Inflammation

Dry tissues become irritated more easily. Mouth breathing can lead to:

- Puffy or inflamed gums
- Tender gum tissue
- Increased bleeding
- More bacteria along the gumline

😴 Snoring & Sleep Apnea: More Than Just Noise

Snoring can be a sign that airflow is restricted. For some people, it may indicate sleep apnea, where breathing repeatedly pauses during sleep.

Sleep apnea has been linked to:

- High blood pressure
- Heart disease
- Stroke risk
- Diabetes
- Memory issues
- Daytime fatigue
- Poor concentration
- Mood changes

Sleep should restore your body—not leave you more exhausted.

💡 Helpful Tips to Try

👃 Support Nasal Breathing

If congestion or narrow nasal passages are an issue, some people benefit from a nasal dilator worn at night to improve airflow.

Try the Intake Breathing Starter Kit here:
https://www.intakebreathing.com/products/starter-kit-10

👄 Mouth Taping (For Appropriate Candidates)

Gentle mouth taping can help keep lips closed during sleep and encourage nasal breathing. This should only be used if you can comfortably breathe through your nose.

📱 Think You Don’t Snore?

Many people have no idea they snore. Try the SnoreLab app to track sounds while you sleep.

🦷 Why Your Dental Team Cares

We often see the signs first:

- Dry mouth
- Worn teeth / grinding
- Inflamed gums
- Frequent cavities
- Tongue scalloping
- Cracked teeth
- Chronic bad breath

These can sometimes point to airway or sleep concerns.

💙 This Month’s Reminder

If you wake tired, snore, grind your teeth, or struggle with dry mouth, it may be time to look deeper into your sleep and breathing patterns.

Better breathing = better sleep = better health = healthier teeth.

We all know citrus fruits, like oranges can be a good source of Vitamin C, but the citric acid in citrus fruits can also do damage to your teeth. To avoid damage from eating citrus fruits and other acidic foods, be sure to brush your teeth at least 30 minutes after eating, as brushing right away can cause more harm than good to your teeth.

🌸 Spring Into April With Us! 🌸

April is all about fresh starts—and we’re excited to bring that energy into your dental care experience! This month, we’re highlighting some exciting new technology in our office and answering a common question we hear all the time: “Do I really need X-rays?” (We promise… we don’t love them either 😅).

✨ Step 1: A Fresh, Gentle Clean with Our Air Polisher ✨

We’re so excited to now offer the PRW Hu-Friedy Air Polisher as part of your hygiene visit!

What is it?
A modern polishing system that uses a controlled stream of air, water, and fine powder to gently remove plaque, stains, and biofilm from your teeth.

Why it’s a game changer:
• 🌿 More gentle and comfortable than traditional polishing • ✨ Removes stains from coffee, tea, and wine more effectively • 🦷 Great for sensitive teeth and gums • 💨 Leaves your mouth feeling extra clean and refreshed

🦷 Step 2: See What We See – GC Tri Plaque ID Gel 🦷

Before we use the air polisher, we apply GC Tri Plaque ID Gel to help guide your cleaning and improve your home care.

What is it?
It’s a special disclosing gel that highlights plaque on your teeth in different colors so we can clearly see where buildup is hiding.

What do the colors mean?
• 🔵/🟣 Purple/Blue: Newer plaque
• 🔴 Pink/Red: Older, more established plaque • 🔷 Light Blue: Acid-producing plaque (the kind most likely to cause cavities)

Why this matters for you:
• Helps you see areas you may be missing when brushing or flossing • Allows us to target those spots more effectively • Gives you personalized tips to improve your routine at home

Key ingredients:
• Food-safe disclosing dyes
• Xylitol to help reduce cavity-causing bacteria • Gentle, non-damaging formula safe for teeth and gums

Think of it as a roadmap to a better clean!

🦷 Let’s Talk X-Rays (Yes… We Know 😬)

We get it—no one gets excited when we say it’s time for X-rays. Honestly, we don’t love taking them either! But they are a crucial part of your care and here’s why:

Why we take X-rays:
• To detect cavities we can’t see during a visual exam • To monitor bone levels and gum health • To check for infections or hidden concerns • To track changes over time and catch issues early

The truth is:
Skipping X-rays can mean missing problems before they become bigger (and more expensive) to treat. We only recommend them when they’re necessary and always keep exposure as low as possible.

Think of them as your teeth’s “behind-the-scenes checkup.”

🌷 Fresh Season, Fresh Smile 🌷

Spring is the perfect time to stay on top of your oral health and experience new technology designed to make your visits more comfortable, personalized, and effective.

If you’re due for your cleaning, we’d love to see you—come experience the difference for yourself!
