Las Vegas is known for its bright lights, world-class entertainment, and around-the-clock excitement. But amidst the fun, many residents and visitors alike face unique dental challenges brought on by the city’s climate, lifestyle, and habits.
Las Vegas is one of the fastest-growing cities in the U.S., with thousands of people moving in and out every year. According to recent statistics, Clark County welcomes over 40,000 new residents annually, while a similar number relocate elsewhere. This constant movement means many people may not have an established relationship with a dentist, leading to gaps in dental care. Additionally, with over 42 million tourists visiting Las Vegas each year, the demand for emergency dental services remains high. Here’s a look at the top five dental issues affecting Las Vegas and how you can keep your smile healthy in the Entertainment Capital of the World.
1. Tooth Decay (Cavities)
Las Vegas is full of delicious dining options, from extravagant buffets to late-night fast food. Unfortunately, frequent indulgence in sugary or acidic foods and drinks (think cocktails, energy drinks, and soda) can lead to cavities. Combine that with busy schedules that often lead to neglected oral hygiene, and tooth decay becomes a widespread problem.
Prevention Tip: Maintain a consistent oral hygiene routine, including brushing twice a day with fluoride toothpaste, flossing daily, and drinking plenty of water to wash away food particles and bacteria. If you’re out late, try chewing Xylitol gum to stimulate saliva production and help protect your teeth.
2. Gum Disease (Periodontitis)
The dry desert climate of Las Vegas can contribute to dehydration, which reduces saliva production. Saliva plays a central role in preventing gum disease by washing away bacteria and neutralizing acids in the mouth. Additionally, smoking—common among casino-goers—further increases the risk of gum disease.
For new residents, adjusting to the desert climate can take time, and many may not realize the impact of dehydration on their oral health. With so many people constantly relocating, some may also delay regular dental visits, increasing the risk of gum disease over time.
Prevention Tip: Stay hydrated by drinking plenty of water throughout the day. Avoid smoking, and if you do smoke, consider quitting for the sake of your oral health. Regular dental check-ups can help detect early signs of gum disease before they become serious.
3. Tooth Sensitivity & Enamel Erosion
Las Vegas’s love for citrus-heavy cocktails, energy drinks, and sodas can lead to enamel erosion, which causes tooth sensitivity. Over time, the protective enamel on teeth wears down, making hot, cold, or sweet foods painful to consume.
Frequent travelers and newcomers may also face changes in their diet that contribute to this issue. Moving from a different climate or region with different water mineral content can sometimes impact tooth sensitivity as well.
Prevention Tip: Limit your intake of acidic beverages and use a straw to minimize contact with your teeth. Rinse your mouth with water after consuming acidic foods and drinks, and consider using toothpaste designed for sensitive teeth.
4. Teeth Grinding (Bruxism)
The fast-paced, high-energy lifestyle of Las Vegas can lead to stress, and one common side effect is teeth grinding. Whether due to job pressures, nightlife, or even dehydration from alcohol and caffeine, bruxism can cause tooth wear, headaches, and jaw pain.
With many new residents moving to Las Vegas for work in the hospitality, entertainment, and tech industries, job-related stress can contribute to increased bruxism. Additionally, long-time residents working in the 24/7 environment of Las Vegas may experience disrupted sleep patterns, which can also lead to unconscious teeth grinding.

Prevention Tip: Stay hydrated, reduce stress through activities like yoga or meditation, and be mindful of your caffeine and alcohol intake. If you notice jaw pain or worn-down teeth, ask your dentist about a nightguard to protect your teeth while you sleep.
5. Dental Emergencies
In a city that never sleeps, accidents happen. Whether it’s a chipped tooth from biting into something too hard, a sports-related injury, or a mishap during a night out, dental emergencies are common in Las Vegas.
The transient nature of Las Vegas means that many people—tourists and new residents alike—may not have a regular dentist to turn to in case of an emergency. This can lead to delays in seeking treatment, worsening the issue.
Prevention Tip: Avoid chewing ice, hard candies, or non-food objects that can cause cracks or fractures. If you participate in sports or recreational activities, wear a mouthguard to protect your teeth. And if a dental emergency does occur, know where the nearest emergency dentist is located.
