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.

Dr. Huynh and Dr. Parks 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 McKinney, TX office so we can take the proper action to protect the health of your mouth.

Summer is almost here, which means a season full of vacations, adventures and great memories is just around the corner for our patients at Pebble Path Pediatric Dentistry.

Everyone wants a glowing and radiant white smile when the sun comes around and we have a few reminders to keep your pearly whites healthy and beautiful over the summer! Try to stay away from drinks that will stain your teeth like coffee, soft drinks, or dark colored juices. Not only will drinks like this weaken your enamel but they will also darken that fabulous smile you're working on! Another tip is to try and focus on brushing your teeth; everyone knows that when busy schedules start picking up, getting a good brushing session in tends to take the backseat! A good tip for keeping your mouth safe from staining and other possible pitfalls is to rinse your mouth with water after any meal you can’t fully brush your teeth after. Your teeth, inside and out, will benefit!

And remember, whether you are headed to a barbecue, a camping trip, or just having fun in the backyard this summer, we want to hear all about it! Make sure to let us know what you’re up to below or on our Facebook page! We also encourage you to post any photos from your adventures!

An overbite is one of the most common malocclusions. If Dr. Huynh and Dr. Parks and our team have diagnosed you with an overbite, you probably have lots of questions. Let’s try to answer some of them!

Just what is an “overbite”?

A malocclusion is another way of saying that you have a problem with your bite, which is the way your jaws and teeth fit together when you bite down. In a healthy bite, the front top teeth project slightly beyond, and slightly overlap, the bottom teeth. A normal overlap is generally considered one or two millimeters.

An overbite is a Class II malocclusion, and means that the upper front teeth cover more of the lower teeth than they should. But that’s a very general definition, and we will diagnose and treat your own, very specific, bite and teeth alignment.

Because overbites aren’t all alike. They might be barely noticeable. Upper teeth might overlap lowers by an extra millimeter or two. In more severe overbites, the upper teeth might cover the lower teeth completely. The amount of overlap and the cause of the overbite will determine your treatment.

What causes an overbite?

Overbites can be dental, caused by tooth alignment, or skeletal, caused by bone development, or a combination of both. They are usually hereditary, so, most often, an overbite is something you’re born with.

The size and position of your jaws, the shape and position of your teeth, all affect your bite alignment. But early oral habits, such as prolonged and vigorous thumb-sucking or pacifier use can contribute to overbite development. Missing teeth and bruxism, or tooth grinding, can also affect the alignment of your bite.

How do we treat an overbite?

There are many types of treatment available. Dr. Huynh and Dr. Parks will recommend a treatment plan based on the type and severity of your overbite. Because some treatments are effective while bones are still growing, your age plays a part as well.

• Braces and Aligners

If dental issues are the main reason for your overbite, braces or clear aligners can be very effective. Rubber bands are commonly used to help bring teeth and jaw into alignment.

• Functional Appliances

If the overbite is caused by a problem with upper and lower jaw development, devices called functional appliances can be used to help guide the growth of the jawbones while a child’s bones are still forming.

For young patients, there are several appliances that can help correct an overbite. Some, like the Herbst appliance, work inside the mouth, while others, like headgear, are worn externally. Your orthodontist will recommend the most effective appliance for your needs.

• Surgical treatment

In some cases, where the problem is skeletal rather than dental, surgical treatment might be necessary to reshape the jawbone itself. This is especially true for adults, whose bones have finished forming.

If we recommend surgery, oral and maxillofacial surgeons are experts in surgical procedures designed to create a healthy and symmetrical jaw alignment. Dr. Huynh and Dr. Parks will work with your surgeon to design a treatment plan, which will usually include braces or other appliances following surgery.

Why treat your overbite?

Sometimes, a very slight overbite won’t require treatment. A serious, moderate, or even mild overbite, though, can lead to many dental and medical problems, including:

• Crooked, crowded teeth
• Worn teeth and enamel
• Problems speaking or chewing
• Difficulty sleeping
• Headaches, facial, and temporomandibular (jaw) joint pain

When you work with our McKinney, TX team to correct your overbite, you’ll not only prevent these unpleasant consequences, but you’ll achieve major benefits as well—a healthy, comfortable bite, and an attractive, confident smile. If you’d like more than an overbite overview, Dr. Huynh and Dr. Parks can provide the specific information and treatment plan you need to make that healthy bite and that confident smile a reality!  

Earth Day began in 1970 as an event to raise awareness of our environment. What began as a single day in April is now recognized around the world to bring attention and education to global environmental issues. Conserving our natural resources, reducing water and air pollution, and developing green technologies are all ways in which we can improve the environment around us.

Reduce, Recycle, and Reuse

One of the easiest ways to participate in Earth Day is by simply reducing the amount of refuse that ends up in landfills. Many communities have recycling programs for paper, plastic, and metal refuse. By keeping recyclable items out of landfills, we reduce the need for new disposal space and the amount of energy needed for burning refuse. Recycling products also helps conserve the resources that are used in making new products.

You can save money by reducing your consumption of many everyday products. Single disposable water bottles can be recycled but they are costly. By using filtered faucet water, you can conserve your financial resources. Disposable paper towels can also be wasteful. Consider reusable cleaning rags for the majority of your chores.

Reusing items saves both the environment and your finances. A large number of products can be re-purposed to create a new item. Old furniture can be remade into a new piece. Old clothing can be used for craft items. If you are not able to find ways to reuse your old items, donate them to a charity. Remember to continue your positive environmental steps on a daily basis.

Other things you can do to improve the environment

Everyone, young or old, can find ways to participate in improving the environment. Some ideas include:

• Planting trees
• Picking up litter
• Reducing energy consumption
• Walking, bicycling, or carpooling to work or school
• Disposing of hazardous waste properly
• Using rain barrels to conserve water for plants

Earth Day is designed to appreciate and celebrate the health of the earth. Keeping the earth healthy is important, but keeping your mouth healthy is important, too. Healthy teeth and gums contribute to your overall health and well-being, so remember to call our team at Pebble Path Pediatric Dentistry to schedule an appointment. Have a happy and healthy Earth Day, from Dr. Huynh and Dr. Parks!
