The Periodontist’s Guide to Chewing Gum and Healthy Smiles

When most people think of chewing gum, they picture a quick way to freshen their breath before a meeting, after lunch, or on the way to see friends. But gum isn’t just about flavor or habit—it actually plays a much bigger role in oral health than many realize. At RVA Periodontics & Dental Implant Center, we care for your gums and teeth from every angle, and chewing gum (when chosen wisely) can be an ally in protecting your smile.

The Science of Chewing Gum

Chewing gum has been around for centuries—ancient civilizations chewed tree resin, while modern gum is made with synthetic bases, sweeteners, and flavors. The real dental benefit of gum doesn’t come from the flavor; it comes from chewing itself.

When you chew gum, your mouth produces more saliva. Saliva is the body’s natural defense system for oral health. It helps to:

• Neutralize acids produced by bacteria and foods.

• Wash away food particles and debris that cling to teeth and gums.

• Deliver minerals like calcium and phosphate to strengthen enamel.

Chewing gum, especially sugar-free gum, has been shown to increase salivary flow by up to ten times the normal rate. This helps reduce the risk of cavities, freshens breath naturally, and keeps your mouth balanced.

Sugar-Free Gum vs. Sugary Gum

Not all gum is created equal.

• Sugary gum: While it may taste good, regular chewing of gum that contains sugar feeds the bacteria in your mouth. These bacteria then produce acids that attack enamel and contribute to cavities, gum irritation, and decay.

• Sugar-free gum: Sweetened with alternatives such as xylitol, sorbitol, or mannitol, sugar-free gum does not feed harmful bacteria. Xylitol, in particular, is noteworthy—it not only starves cavity-causing bacteria but also reduces their ability to stick to teeth and gums.

The American Dental Association (ADA) only awards its Seal of Acceptance to sugar-free gums that meet rigorous testing standards. When choosing gum, look for this seal—it’s a simple way to know your gum is helping, not harming, your oral health.

Gum Health and Chewing Gum

As a periodontics practice, we place special emphasis on the health of your gums and supporting bone structures. So, how does gum affect your gums?

1. Increased Saliva Flow Helps Fight Gum Disease

Since saliva washes away bacteria and plaque, chewing sugar-free gum may support gum health by keeping bacteria levels lower throughout the day. This is especially helpful after meals when brushing isn’t immediately possible.

2. Fresh Breath vs. Masking Problems

Chewing gum can mask bad breath, which sometimes signals deeper issues like gum disease or dry mouth. If you find yourself relying heavily on gum for fresh breath, it might be time for a periodontal exam to rule out gum inflammation or infection.

3. Gentle Stimulation for Gums

Chewing gum lightly massages the gums and keeps tissues active. For most people, this stimulation is healthy. However, if you have advanced gum disease or sore gums, gum chewing may feel uncomfortable—and that’s a sign to consult with your periodontist.

Chewing Gum and Dental Implants

Many of our patients at RVA Periodontics have dental implants, and they often ask: “Can I chew gum with implants?”

The good news is yes—you can, but with some caveats:

• Healing phase caution: Immediately after implant surgery, avoid gum entirely until your periodontist confirms healing is progressing properly.

• Stickiness factor: Gum is sticky and can cling to implant crowns or bridges. Sugar-free gum is less of a problem, but if you find gum pulling at your restorations, it may not be the best habit for you.

• Saliva benefit: Once implants have healed, chewing gum can actually support implant longevity by promoting a healthier oral environment.

Always follow your individual post-surgery instructions before reintroducing gum into your routine.

Chewing Gum vs. Brushing and Flossing

It’s important to remember: chewing gum is not a substitute for brushing or flossing.

• Brushing twice a day with fluoride toothpaste remains essential for removing plaque from tooth surfaces.

• Flossing or using interdental cleaners daily is critical for cleaning between teeth and below the gumline, areas gum chewing cannot reach.

• Gum chewing is a supplemental practice—helpful, but never a replacement.

Think of chewing gum as the “support act” in your oral hygiene routine, not the “main event.”

The Best Times to Chew Gum

Timing matters. To maximize gum’s benefits, chew:

• After meals: 20 minutes of chewing sugar-free gum can reduce acid attacks on enamel and support digestion.

• When water isn’t available: If you can’t rinse your mouth, chewing gum is the next best option.

• During dry mouth: For patients with xerostomia (dry mouth), gum can provide temporary relief by stimulating saliva production.

Special Considerations

Children and Gum

Chewing gum can be safe for children, but supervision is key. Always ensure they understand the gum is not to be swallowed and choose sugar-free varieties. For some children, especially those prone to cavities, xylitol gum may be recommended.

TMJ (Jaw Joint) Issues

Patients with temporomandibular joint (TMJ) disorders should be cautious. Excessive gum chewing can strain the jaw and worsen symptoms. If you have jaw discomfort, limit gum chewing and consult your periodontist.

Patients with Braces or Orthodontic Appliances

Traditional gum may stick to brackets and wires. However, there are orthodontic-approved gums designed not to stick, which can safely provide the saliva-boosting benefits.

Beyond Oral Health: Surprising Benefits of Chewing Gum

Believe it or not, chewing gum has been linked to benefits beyond the mouth:

• Cognitive performance: Some studies suggest chewing gum improves focus, memory, and concentration.

• Stress relief: Chewing can help release nervous energy and reduce stress.

• Digestive aid: Chewing gum after meals may reduce acid reflux by stimulating saliva that neutralizes stomach acid.

While these benefits are secondary to oral health, they demonstrate how something as simple as gum can positively influence daily life.

How RVA Periodontics Recommends Using Gum

At RVA Periodontics & Dental Implant Center, our philosophy is personalized care. While chewing gum can be a healthy habit, it’s not right for everyone. Here’s what we generally recommend:

1. Choose ADA-approved sugar-free gum, ideally with xylitol.

2. Chew for 15–20 minutes after meals to support saliva flow and acid neutralization.

3. Do not rely on gum as your only strategy for managing oral health. It should complement brushing, flossing, and regular professional cleanings.

4. Pay attention to your body: If chewing gum causes jaw pain, gum soreness, or discomfort with implants, discontinue and let us know.

5. Use gum as an opportunity for self-awareness: If you’re constantly masking bad breath with gum, that’s a sign to schedule a periodontal checkup.

Periodontics, Prevention, and the Bigger Picture

Periodontal health is about more than avoiding cavities—it’s about keeping the entire support system of your smile healthy. Gum disease is the leading cause of tooth loss in adults, but it’s also one of the most preventable conditions with proper care.

Chewing gum plays a small but meaningful role in prevention:

• It reduces plaque acids between brushing sessions.

• It lowers cavity risk when sugar-free.

• It supports healthier gums by reducing bacterial buildup.

Combined with professional periodontal care, gum can help patients maintain healthier smiles for life.

When to Talk to Your Periodontist About Gum

While most patients can safely enjoy chewing gum, there are times when you should ask your periodontist for guidance:

• You have gum disease or symptoms such as bleeding gums, swelling, or persistent bad breath.

• You’ve recently had dental implant surgery or other periodontal procedures.

• You experience jaw pain or TMJ discomfort while chewing gum.

• You’re unsure which types of gum are safe for your unique dental situation.

At RVA Periodontics, we believe no question is too small when it comes to your oral health. If gum chewing is part of your lifestyle, we want to help you make it a healthy choice.
