A Few Things Your Dentist Would Never Put Inside Their Mouth

Dentists are the unsung heroes of oral health, diligently working to ensure that our teeth remain as healthy, bright, and beautiful as possible. But did you know that their expertise extends far beyond just cleaning and fixing teeth? They also know quite a bit about how to maintain a safe and hygienic environment inside the mouth—and this includes knowing what objects to never put near their pearly whites! Continue reading below to learn a little more about a few of the things your dentist thinks you should never consume or stick inside your mouth, to avoid an unexpected and unpleasant dental injury!

What Does My Dentist Avoid Eating?

Everyone loves food—even your dentist! However, there are certain items out there that can cause many problems for your teeth and gums, including:

  • Hard candies – Items like lollipops, jawbreakers, Jolly Ranchers, and more can all pose a serious threat to one’s teeth. When you eat these, your mouth is exposed to their high amounts of sugar for a longer period of time! They can also chip or crack your teeth.
  • Lemons and other citrus – Lemons are highly acidic and can cause enamel erosion and a pH imbalance inside of your mouth, as can other citrus items like limes and grapefruit.
  • Potato chips – Chips might be a tasty snack, but they’re high in both starches and sugars which can lead to enamel erosion. Opt for something healthier instead, like fresh fruit, yogurt, or cheese.
  • Ice cubes – Biting into ice cubes is an easy way to fracture your teeth. Be sure to only use them to chill your drinks!

What Non-Food Items Are Problematic?

Sometimes we might find ourselves putting objects into our mouth that aren’t food; as convenient as this might seem at times, it’s ill-advised. Here are some items your dentist would absolutely never put in their mouth:

  • Fingernails – Biting your fingernails is pretty unsanitary, as it can easily transmit bacteria into your mouth. It can also flatten the edges of your front teeth, creating cracks in your enamel.
  • Pens, pencils, and office supplies – These items are also often riddled with germs that can easily spread throughout your body once they enter your mouth. Plus, many of them are hard and can damage your teeth.
  • Cigarettes – Smoking and using tobacco is notoriously bad for your health in general, and regularly smoking cigarettes can lead to some serious health problems including oral cancer. It’s simply not worth it!
  • Other people’s toothbrushes –Sharing toothbrushes can spread bacteria and make you very sick, not to mention it can expedite all sorts of problems—even cavities are contagious!

It’s also worth noting that you should never try to use your teeth as tools to open packaging or unscrew bottle caps, nor should you hold items like car keys or jewelry inside your mouth. Your dentist is perhaps your biggest ally when it comes to keeping your smile healthy and beautiful, so it’s in your best interest to heed their advice when it comes to these problematic items.

I've been coming to this practice for years now since moving to the Raleigh area. The office is always clean and organized and the staff have always been friendly and communicative. Also, the TV's mounted to the ceiling are a nice touch! I've been seeing Dr. Laster for several years before our insurance changed causing me to change to Dr. Rensch. Both are so easy to talk to and always made me feel at ease.

From beginning to end 5/5! I thought I was experiencing a dental 911. I submitted an inquiry at 11:30pm and by 8am the next morning, Deidra (front office staff) was already leaving me a message. She was so sweet and patient at 8am lol. After our initial conversation, I informed all follow up dentists “I found my dentist office” but thank you so much! Today I was welcomed with the same energy from Diedre to Britany then finally Dr.Wrench. The music playing throughout the office was fantastic; ie music selection and volume. The TV’s on the ceiling and wall made my procedure so painless and enjoyable! I watched an entire Christmas movie lol! Dr. Wrench (apologies for spelling) made my teeth absolutely perfect! I left telling my friends and family I have a million dollar smile! 😊 I can tell he wanted them perfect and he did! Thank you all so much for being amazing! Sincerely, Your next patient.

Dr. Laster and Dr. Rensch go above and beyond for their patients. I have seen both for various treatments and I always feel comfortable and heard. They take time to listen and to talk with you. They explain your options and work with you to develop the best plan for your care. They are always upbeat and positive and you can tell they truly love what they do. The front desk staff is exceptional as well. Deidre is so caring and very sweet. She’s efficient, understanding and conscientious of your time. I highly recommend.

Connections Dentistry was great! The staff is so friendly and truly cares about their patients. My appointment was quick, and honestly the best dental experience I’ve had. They are great about offering helpful solutions without making you feel like you are being reprimanded… which was the reason I was putting off the dentist. 100% recommend!
