A strong, healthy smile is built on a strong, healthy foundation. Let’s take a moment to explore just what creates that foundation—your roots.

The Root of the Matter

The visible part of your tooth is called the crown. And while we spent the great majority of our time thinking about what goes on above the gum line—brushing, flossing, whitening, sealing, preventing cavities—the roots, the parts of the teeth below the surface, are also essential to our dental health.

• What’s inside the root?

The inside of each tooth holds pulp, which is living tissue made of nerves, blood vessels, and connective tissue. The nerves in the pulp allow us to feel pain when a tooth is damaged, decayed, or infected. Tiny blood vessels provide oxygen and nutrients to the cells.

The inside of each root also contains pulp, located in one or more root canals. These canals are small tunnels that travel from the pulp chamber to the tip of each root. Nerves and blood vessels connect pulp tissue to the nervous and circulatory systems in the body, entering and exiting the tooth from very small openings in the root tip.

• What’s outside the root?

On the outside, while roots look like crowns, they’re covered with a different protective surface. Roots are covered by cementum rather than enamel. This is a hard tissue, but not as hard as enamel. But cementum has another advantage—it not only helps protect our teeth, it helps them stay anchored in our jaws. (More on this below.)

• How many roots are we talking about?

The number varies, not just depending on the tooth, but depending on the individual. Most adults have 32 adult teeth: eight incisors, four canines, eight premolars, eight molars, and four wisdom teeth, or third molars. Because the number of wisdom teeth can range from four to zero, though, that total can be smaller.

Rooted to the Spot

The reason that you can rely on your teeth for a lifetime of chewing, biting, and grinding food is the fact that they’re so securely anchored in the jaw.

• Alveolar bone in the jaw contains a socket for each tooth.

• A thin layer of connective tissue called the periodontal ligament lines the socket and surrounds each root. It’s filled with fibers that attach to the root’s cementum covering and to the alveolar bone, holding the tooth securely in place.
• The periodontal ligament not only anchors the tooth, it cushions it from the daily pressure of biting and chewing.
• Finally, the gums surround the teeth and bone, protecting them from bacteria and plaque.

Even though this design is very secure, there are situations where the root becomes vulnerable. In that case, you should see our doctor at our Ashland office right away. Our goal is for you to keep your teeth healthy and strong, and for a lifetime!

our doctor and our team at Ashland Dental Care get this question a lot. Wisdom teeth are the last teeth to come in, once young people get their adult teeth. Because they are the last teeth to break through the gums, they are often called the third molars. There are four wisdom teeth: two on each side of the top and bottom of the mouth.

There is no hard-and-fast rule that says everyone must have the wisdom teeth removed. There are certain situations in which they either cause problems directly, or create a situation where there is a greater likelihood problems will arise eventually.

Impacted wisdom teeth

If our doctor and our team say you have a soft tissue impaction, it means your wisdom tooth is covered by gum tissue that is preventing it from erupting — most likely because your mouth is too small to provide the tooth with the room it needs to emerge.

The term “partial bony impaction” means that gum tissue is covering the wisdom tooth, but part of the jaw bone is also covering it, in which case there is no room in your mouth for the tooth to erupt. The opposite end of this spectrum is a complete bony impaction, where the wisdom tooth is completely covered by gum tissue and the jawbone, which prevent it from ever erupting.

The importance of removing impacted wisdom teeth

Dentists often want to remove impacted wisdom teeth because of the likelihood that they will cause problems, or because a problem already exists. One such problem is pericoronitis, an acute abscess that affects partially impacted wisdom teeth. Food, bacteria, and other mouth debris can become lodged under the gum flap that covers the wisdom tooth, which prevents it from erupting. Pericoronitis symptoms include pain, swelling, and the presence of an abscess.

Regular dental checkups will enable your dentist to keep an eye on your wisdom teeth, especially if they have some type of impaction. our doctor and our team at Ashland Dental Care typically recommend removal of impacted wisdom teeth because of the likelihood that severe infections such as pericoronitis will develop.

Cancer has become a common word, and it seems like there is new research about it every day. We know antioxidants are important. We know some cancers are more treatable than others. We know some lifestyles and habits contribute to our cancer risk.

Smoking increases our risk of cancer, as does walking through a radioactive power plant. But there is a direct link to oral cancer that you many may not know about—the link between HPV (Human Papilloma Virus) and oral cancer.

This may come as a shock because it has been almost a taboo subject for some time. A person with HPV is at an extremely high risk of developing oral cancer. In fact, smoking is now second to HPV in causing oral cancer!

According to the Oral Cancer Foundation, “The human papilloma virus, particularly version 16, has now been shown to be sexually transmitted between partners, and is conclusively implicated in the increasing incidence of young non-smoking oral cancer patients. This is the same virus that is the causative agent, along with other versions of the virus, in more than 90% of all cervical cancers. It is the foundation's belief, based on recent revelations in peer reviewed published data in the last few years, that in people under the age of 50, HPV16 may even be replacing tobacco as the primary causative agent in the initiation of the disease process.” [http://www.oralcancerfoundation.org/facts/]

There is a test and a vaccine for HPV; please discuss it with your physician.

There are some devices that help detect oral cancer in its earliest forms. We all know that the survival rate for someone with cancer depends greatly on what stage the cancer is diagnosed. Talk to our doctor if you have any concerns.

Please be aware and remember that when it comes to your own health, knowledge is power. When you have the knowledge to make an informed decision, you can make positive changes in your life. The mouth is an entry point for your body. Care for your mouth and it will care for you!

As adults, we often wish our teeth could be as white as they were when we were small children. Baby teeth have thinner and whiter enamel than adult teeth, and those brilliant smiles are a result! But occasionally, you may be surprised to discover some staining or discoloration on those lovely first teeth. You might be tempted to apply a whitening product to your child’s teeth, but, please—read on!

Causes of Staining

• Improper Brushing—Often, a loss of tooth whiteness means that plaque has built up on the tooth surface. Careful brushing is needed to remove bacteria and plaque, and if your child isn’t brushing at least twice a day for two minutes, discoloration can be the result.
• Medications—When given in liquid form, or when added to formula or food, iron supplements can cause dark grey staining on the teeth. Medications taken by a mother while pregnant or breast feeding, such as tetracycline, can also lead to discoloration.
• Injury—If a tooth suffers a serious injury, the tooth can darken because of changes inside the enamel.
• Health conditions—Certain health problems can cause tooth discoloration, or sometimes children are born with weaker enamel that is more likely to stain.

If you have noticed any staining on your child’s primary teeth, call our Ashland office. Simple stains can often be removed with better brushing techniques, and we can clean other surface stains in the office. Staining caused by an injury or a health condition is something we can discuss in detail with you. We can even use some professional whitening methods if those are indicated.

Why not just buy a home whitening kit for your child? There are several important reasons to leave these products on the shelf while your child is young.

• Whitening kits are designed for adults. They have been tested for adult teeth in adult trials. Check the box for age appropriate use. Most products are not recommended for pre-teen children.
• Remember that thinner enamel we mentioned earlier? Add to that the delicate skin of young children, and it’s sensible to be cautious about using a bleaching agent that can cause mouth and tooth sensitivity even in adults.
• There is no body of evidence available as to the short and long term effects of using these products on children.

If you are concerned about the brightness of your child’s smile, please talk to our doctor. We can recommend better ways to brush at home, clean your child’s teeth in the office, or suggest professional methods of whitening if there are physical or psychological reasons that it would be valuable. But while your child is young, those off-the-shelf whitening products can wait a few more years.
