Alcohol and Oral Health: What You Should Know

By Dr. Cassia Braulio – Glen Erin Dental

Dear Patients,

Whether it’s a toast at a celebration or an occasional glass of wine with dinner, alcohol is part of many people's social routines. But did you know that regular or excessive alcohol consumption can quietly take a toll on your oral health?

As your dental care provider, I want to share some important insights into how alcohol affects your teeth, gums, and overall oral well-being — so you can make informed choices for your health.

1. Tooth Decay & Enamel Erosion

Alcoholic beverages — especially cocktails, wine, and beer — often contain sugars and acids that can damage your teeth over time. These acids weaken the enamel (the protective layer on your teeth), making you more susceptible to:

• Tooth sensitivity

• Cavities

• Enamel erosion

If your drink includes sugary mixers like soda or juice, the damage is even greater. These ingredients create an acidic environment where cavity-causing bacteria thrive.

2. Dry Mouth (Xerostomia)

Alcohol can reduce saliva flow, leaving your mouth dry. This may not seem serious at first — but saliva is essential in:

• Neutralizing harmful acids

• Washing away food particles and bacteria

• Protecting your enamel

A dry mouth allows bacteria to build up more easily, increasing your risk for:

• Cavities

• Bad breath

• Gum disease

• Oral infections like thrush

3. Gum Disease (Periodontal Disease)

Research shows that excessive alcohol consumption is linked to an increased risk of gum disease. This can include:

• Swollen, bleeding gums

• Receding gum lines

• Bone loss around the teeth

• In advanced stages, even tooth loss

Alcohol alters your body’s immune response and can promote the growth of acid-producing pathogens — the harmful bacteria responsible for damaging gum tissue.

4. Oral Cancer Risk

Perhaps one of the most serious risks associated with chronic alcohol use is the increased chance of developing oral cancer. This risk is even higher when alcohol use is combined with tobacco.

Long-term alcohol exposure can change the cells in your mouth and throat, increasing the risk of:

• Oral cancer (tongue, cheeks, lips)

• Throat cancer

• Esophageal cancer

Regular dental check-ups are vital, as we routinely screen for early signs of these conditions.

My Advice to You

Here at Glen Erin Dental, our role is not just to treat but to educate and empower you. If you consume alcohol — occasionally or more frequently — consider the following tips:

• Rinse your mouth with water after drinking

• Avoid sugary mixers

• Never skip brushing and flossing afterward

• Stay hydrated to promote saliva flow

• Visit us regularly for cleanings and screenings

And most importantly, don’t hesitate to discuss your habits openly with us. There is no judgment here — only a commitment to helping you protect your health.

Cheers to a healthier smile!

Warmly,
Dr. Cassia Braulio
