It is common to experience dentine hypersensitivity, with symptoms ranging from moderate to severe. Why does it happen and how do you know if this sensitivity is something to be concerned about? The first step is to determine the cause.

The most common cause of the sensitivity is exposure of the dentin. Dentin is the layer immediately surrounding the nerve of the tooth. It is alive and usually covered by the gum tissue. When gum recession is present hypersensitivity is common. Other contributors to temporary tooth hypersensitivity include teeth whitening and dental procedures such as fillings, periodontal treatment, and braces placement or adjustment. These are temporary and should be of no concern.

Permanent hypersensitivity, however, may require treatment. To understand the cause of sustained hypersensitivity, let us explain the structure of dentin and why it serves as a ‘hot spot’.

The dentin contains a large numbers of pores or tubes that run from the outside of the tooth to the nerve in the center. When dentin tubes are exposed, there is a direct connection between the mouth and dental pulp, which houses the nerve and blood supply of the tooth. External stimuli, such as mechanical pressure (tooth grinding or clenching - bruising the ligaments holding the teeth in place), temperature changes, as well as chemical stimuli (sweet–sour) are transmitted to the pain-sensitive dental pulp and activate nerve endings. A short and sharp pain is the result. These external stimuli cause fluid movement in the open tube that is transmitted as pain sensations. Something needs to be placed into the dentin tube to plug it and stop this fluid movement.

The first step in doing something about dental hypersensitivity is to determine the cause; our professional team at Northwest Smile Design can help you with this. Whether the sensitivity is due to exposed dentin or an underlying cause such as abscess or decay, corrective measures are needed. Contact us sooner rather than later so Dr. Kelly Peterson can reduce the sensitivity, and provide you with some relief!

Sure, you brush your teeth and floss regularly, so you might think you’re off the hook when it comes to the dental chair. However, it’s just as important for adults to get regular dental exams as it is for kids. Cavities are common among adults, with 92% of people aged 18 to 64 having had cavities in their permanent teeth, according to the National Institute of Dental and Craniofacial Research.

How cavities form

Our mouths are teeming with hundreds of types of bacteria. Some are helpful and maintain good health, while others are harmful. Certain types of bacteria process the sugars in food and release acid in return. Although minor decay can be naturally reversed by your body, Dr. Kelly Peterson and our team at Northwest Smile Design will tell you that eventually the acid wears away the enamel and creates small holes in the surface of teeth.

Cavity prevention for adults

Some people are naturally more prone to cavities than others. However, making a few lifestyle changes can dramatically reduce your likelihood of developing cavities.

• Food choices. Eating plenty of fresh fruits and vegetables increases saliva production, and reduces cavity risk. It is also important to avoid foods that get stuck in the ridges of your teeth. Candy, cookies, and chips should be eaten sparingly.
• Beverages. Most people know that drinking soda contributes to tooth decay. However, fruit juices and energy drinks also contain large amounts of sugar. Whenever possible, replace these sugary beverages with tea or water, which rinses your mouth and prevents decay.
• Fluoridated water. Fluoride is a naturally-occurring chemical that facilitates enamel growth. Most municipal water supplies are fortified with fluoride, so drinking tap water is a great way to keep teeth healthy. People with well water may use fluoridated toothpaste or other supplemental forms of fluoride to decrease cavity risk.
• Brush teeth and floss frequently. Gently brushing teeth several times a day removes the harmful bacteria that cause cavities to develop. If possible, brush your teeth after each meal or when drinking sugary beverages. Flossing regularly removes small particles that get trapped between teeth, which further decreases tooth decay.

One of the most important steps in cavity prevention is visiting your dentist at least twice a year. Consistent dental exams ensure that cavities are caught early, before they cause major damage to your teeth.

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 Dr. Kelly Peterson 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!
