Tooth Worms? The History of Cavities and Tooth Fillings

May 15th, 2015

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. Thomas and Andrew Watkins 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 Bloomington, IN office so we can take the proper action to protect the health of your mouth.

What should I use to clean my baby’s teeth?

May 8th, 2015

You might think babies don’t need to brush their teeth, especially when they don’t have any. But by starting good habits like brushing when your child is young, you can lay the foundation for them to continue those good habits into adulthood.

When do I start?

The best time to start brushing your baby’s teeth is before he or she has any. Develop the habit of wiping your baby’s gums with a wet, soft washcloth or gauze every day. There is no need to use toothpaste, just wrap the gauze or cloth around your finger, moisten it with a little water, and gently rub it over the gums.

This helps your little one get used to brushing while it eliminates bacteria in the mouth that can harm emerging teeth. You don’t need to apply a lot of pressure or even take very long: just a quick, gentle rub over the gums will do it.

What do I use?

When your child’s teeth begin to come in, you will need to switch from a cloth to a baby toothbrush. Find one that has a grip big enough for your hand, but a head that is small enough to maneuver easily in your infant’s mouth.

You don’t need to use any toothpaste until your son or daughter is about a year old. Even then, though, you’ll want to use just a tiny amount: about the size of a grain of rice. When your toddler is about two years old, you can use a pea-sized amount.

By around six years of age, your child will probably rinse and spit without your help. At that point, you may want to introduce a child-friendly fluoride mouthwash.

How do I do it?

Your child probably won’t be able to brush his or her teeth alone until about the age of five or six. This means that you will need to do it. To brush your child’s teeth, gently use the brush over all the teeth and gums, even areas where the teeth have not come in yet.

As your child grows and becomes more independent, you can allow him or her to hold the toothbrush while you guide your child’s progress. Make sure you talk to your child while you are brushing, and explain why you brush: what you are doing and how you are doing it.

In addition to regular visits with Drs. Thomas and Andrew Watkins, instilling good oral health habits in your child early on will ensure a lifetime of good dental health.

Proper Brushing Techniques

May 1st, 2015

Brushing your teeth properly removes the food particles and bacteria that can lead to tooth decay and gum disease. However, you do not want to scrub your teeth or gums heavily. A heavy hand can lead to tooth and gum erosion, as Drs. Thomas and Andrew Watkins and our staff see all too often.

You should also use a soft bristle toothbrush to avoid damaging the surface of your teeth. Make sure the head of the brush fits in your mouth, because if it is too large you will not be able to reach all tooth surfaces. Follow these steps to ensure you are brushing properly.

  1. Use a small amount of toothpaste on your brush. The recommendation is a pea-sized amount or thin strip on the bristles.
  2. Hold your toothbrush at a 45-degree angle to the surface of your teeth, angling towards your gums. Use a circular motion on all exterior tooth surfaces, and avoid back-and-forth “scrub” brushing.
  3. Once you have cleaned the outer surfaces, hold the brush vertically and clean the inner teeth surfaces — the side of your teeth that face your tongue. Do not forget the inner surfaces of your front teeth.
  4. Finally, finish by cleaning all the chewing surfaces of your teeth. You need to maintain a gentle touch, but make sure you get into the full depth of your molars. The entire process should take about two minutes.

Drs. Thomas and Andrew Watkins and our staff recommend changing your toothbrush every three to four months for best results. Do not forget to clean your tongue, which helps remove excess bacteria from your mouth. Special brushes are available just for cleaning your tongue, and they are easy to use.

Proper care of your teeth also requires flossing on a regular basis. Flossing can be performed before or after you brush. Following up with a quality mouthwash will provide you with even more protection. Do not be afraid to ask the Watkins Family Dental Care team for tips on proper brushing and flossing.

What exactly is a root canal?

April 24th, 2015

Hearing that you need a root canal can be highly intimidating. What is a root canal? It is the removal of the nerve supply from the tooth. Here, Drs. Thomas and Andrew Watkins will describe the parts of a tooth and explain the reasons for a root canal and how it is done when you visit us in our Bloomington, IN office.

Your tooth is made up of many layers. The outside layer is called enamel and is made of minerals. The middle layer is dentin, which is also a calcified tissue, but less dense. The center of the tooth is called the pulp, and that hosts the nerves and blood vessels. A root canal is the removal and replacement of this center with a sterile filling.

A root canal is needed when an infection spreads to the center of the tooth. This can be from trauma (recent or previous), a cavity, a severe crack, or other compromise that causes nerve damage. An X-ray and examination are required to see if a root canal is needed. Symptoms may include but are not limited to pain, swelling, change in tooth color, and over-reaction to temperature change or pressure.

When it is time to begin, you’ll receive local anesthesia (via injection) to make you most comfortable. A rubber dam is used to isolate the tooth, while other equipment determines the nerve location and maintains a sterile working environment. All of the infected area is removed including the nerve tissue and blood vessels. Then, medicines are used to sterilize and alleviate any pain. Next is the placement of a filling material in the spot where the nerve used to be.

When your nerve and blood supply are taken away, the tooth is non-vital, or dead, and can become weak and fragile. If your tooth is badly decayed, a large portion of it will have to be removed. It is recommended to place a crown on the tooth to keep the enamel from breaking or falling apart. If you do not get a crown, you could eventually lose the tooth to more decay or infection. The tooth could also break off completely and you would have to have an extraction. The crown fits over the top of the tooth and secures it from breaking down.

A root canal saves the life of a tooth that would otherwise succumb to further infection and eventually extraction. Infection is the cause of most-needed root canals. If you are ever unsure what is happening at your appointment, don’t be afraid to ask questions so you understand the procedure completely.
