Tooth Worms? The History of Cavities and Tooth Fillings

January 14th, 2026

Scientists have discovered tooth decay in specimens that are more than 15,000 years old. The ancients once thought that cavities were caused by something called “tooth worms” … Eew! They didn’t exist, of course, but how else could humans explain the holes that cavities make in teeth?

The appearance of cavities on a widespread basis is often traced to the rise of farming. The new diet filled with grains and carbs made our mouths a haven for cavity-causing bacteria. As we added more sugar to our diets, our teeth got worse.

The “tooth worm” idea didn’t completely disappear until the 1700s when scientists finally began to understand the process of dental caries. Once that part of the puzzle was solved, they began focusing on filling existing cavities and preventing new ones.

Dental Fillings Come of Age

Many different materials, including beeswax, cork, aluminum, tin, and even asbestos, have been used to fill the holes caused by dental decay. Sometime in the mid-1800s, however, dentists began to use metal fillings such as gold, platinum, silver and lead amalgams.

The amalgam we use today is mixed from liquid mercury, silver, tin, copper, zinc, and other metals, but some patients still like the look of a gold filling. Newer options include composite-resin fillings, which are made from a tooth-colored mixture of plastic resin and finely ground glass-like or quartz particles that form a durable and discreet filling. Porcelain or ceramic fillings are natural in color, but more resistant to staining.

Drs. Jay Corley and Rebecca Lauck can help decide which filling is best for you, based on cost as well as your dental and lifestyle needs. You may not have “tooth worms,” but if you have cavities, contact our Keller, TX office so we can take the proper action to protect the health of your mouth.

Is Charcoal Teeth Whitening Safe?

January 7th, 2026

Health and beauty trends surface on the web every day, and it can be difficult to tell which ones are worth your time, or even safe, for that matter. Perhaps one of the biggest dental trends recently on Facebook, YouTube, and Instagram has been teeth whitening through brushing with activated charcoal.

Unfortunately, charcoal whitening isn’t everything the Internet makes it out to be. Activated charcoal isn’t what you use to grill at a summer barbecue; it’s an oxidized substance made from peat, coal, wood, coconut shell or petroleum heated with a gas.

Toxins and surface stains can cling to charcoal due to its adhesive qualities, which is why some people declare it’s perfect for removing discoloration on teeth. Although it may show quick results initially, charcoal is nothing more than a temporary solution.

The abrasive texture may roughen up enamel, which will make it easier for future stains to stick to the surface of your teeth. They may show stains shortly after you use charcoal on them, and may become even more discolored than before.

It’s crucial to emphasize the results of damaged tooth enamel because it cannot replenish itself, which means any damage is permanent. People with receding gums or sensitive teeth especially should steer clear of charcoal because it can make brushing too harsh and worsen sensitivity.

Long-time use can deplete enamel, which over time exposes dentin: the soft, yellowish layer in the tooth. This puts you at a higher risk for cavities, tooth discoloration, and complicated dental problems such as periodontal disease in the future.

The American Dental Association does not approve of charcoal as a safe means for whitening teeth. If you do choose to use it, do so with caution.

Charcoal should be used once every other week at the most, even if your teeth feel fine. The only proven ways to whiten teeth safely are with ADA-approved whitening products or in-office bleaching treatments overseen by a dental professional.

Before you begin any whitening treatment at home, consult with Drs. Jay Corley and Rebecca Lauck to make sure your teeth won’t be harmed in the process. If you are already experiencing sensitivity, stop charcoal use immediately and make an appointment with our office right away.

December 31st, 2025

It’s no secret that New Year’s Eve is one of the most widely celebrated holidays in the world. Drs. Jay Corley and Rebecca Lauck and our team love it too. It’s a fresh start, another year of surviving the crazy world we live in, a time to refocus on the things we want for ourselves, a celebration with those we love … the list goes on.

Dozens of countries welcome the New Year with over-the-top parties and celebrations. Because it’s a public holiday, many offices, businesses, and schools close for the day. As you think about your plans for this holiday, here are some fun facts about New Year’s that might surprise you!

Can you guess what the most common New Year’s resolutions are? You may already have one or two of these on your own personal list. The top five New Year’s resolutions are: to quit smoking, get a new job, lose weight, increase personal savings, and return to school. Just remember that coming up with a concrete plan to reach your goals is the surest way to achieve your resolutions!

About one million people brave the cold to watch the New Year’s Eve ball drop in New York City’s Times Square in person. Yes, that’s one million! This event is one of the most iconic celebrations in the world. People travel from all over just to experience it, but you can watch from the warmth and comfort of your living room.

If you’re not a fan of cabbage, collard greens, black-eyed peas, or ham hocks, you might want to revise your tastes. All these foods are all regarded as lucky fare on New Year’s Day. Unless you’re allergic, of course!

For many people in Mexico and Latin America, eating 12 grapes at midnight is a tradition that brings good luck in the 12 coming months. Most people even make a wish per grape!

Tips for a Whiter Smile

December 24th, 2025

Everyday life can take a toll on the whiteness of our teeth: Foods we love as well as soft drinks and coffee can stain them over time. Poor brushing and flossing can also leave behind tooth stains. Even injuries to teeth or gums can cause some yellowing, and in certain cases, medicines can contribute to discoloration.

So don’t get discouraged if you notice your smile has dimmed. You can definitely take action to restore the natural beauty of your teeth. Here are some of the best ways to whiten them:

  1. Drink through a straw or cut back on coffee and soft drinks to reduce risk of stains.
  2. Brush and floss every day.
  3. Try a whitening toothpaste or mouthwash.
  4. Visit our Keller, TX office every six months for regular cleanings.

We also offer in-office professional whitening at our Keller, TX office. These whitening products are much more effective than whiteners you can buy at the store and are completely safe. Since they’re stronger, application by a member of our team is essential to achieve the best results.

Still, some teeth can resist bleaching. If that’s the case, we can try several other techniques, such as deep bleaching that applies whitening agents over several visits, veneers and bonds that cover existing stains with a whiter, brighter surface, or laser whitening.

If a whitening session is something you’d like to pursue, be careful about whom you trust to perform the procedure. Avoid using “bleaching stations” in shopping malls or at fairs. These so-called whitening techniques can irritate your teeth and gums, and leave them highly sensitive to pain.

Also, operators of these whitening stands will make customers apply the bleach themselves, to avoid charges of practicing without a license. That should serve as a red flag and a caution to seek trained professionals like Drs. Jay Corley and Rebecca Lauck, instead.
