While Dr. Kari Woo and our team tell you daily oral hygiene habits, such as brushing and flossing, are essential to optimal oral health, regular dental checkups at Kari Woo, DDS ensure your teeth are treated to a deeper level of cleaning.

We recommend for most of our patients to have a cleaning at our Issaquah, WA office at least every six months. In addition to a thorough cleaning and polishing of your teeth, visits with Dr. Kari Woo help us detect and prevent the onset of tooth decay and gum disease, also known as periodontal disease. During your visit, we will check the health of your mouth, teeth, gums, cheeks, and tongue for signs of any decay or disease. We will also check old fillings and restorations as these can wear away over time due to chewing, clenching, or grinding.

If you are predisposed to any oral diseases, Dr. Kari Woo may recommend checking in with us more often than every six months. We want your teeth to get the professional attention they deserve! If you are overdue for your next cleaning, give us a call at our Issaquah, WA office to schedule a checkup! See you soon!

Nearly 40,000 people are diagnosed with oral cancer annually in the United States, with more than 8,000 dying every year from the disease. Oral cancer has a higher death rate than many other common cancers, including cervical cancer, testicular cancer, Hodgkin’s lymphoma, and thyroid or skin cancers. The high death rate results from the fact that most oral cancers go undiagnosed until the disease is well advanced and has spread to another part of the body, most often, the lymph nodes in the neck.

Dr. Kari Woo and our team want you to know that cancers of the mouth and throat, which account for about three percent of all cancers in the United States, are largely preventable. However, we want you to know about certain risk factors that affect the likelihood of developing the disease.

• Use of tobacco products including smoking cigarettes, cigars or a pipe, or chewing tobacco all elevate risk for developing oral cancer. Tobacco use especially, is a serious risk factor because it contains substances called carcinogens, which harm cells in your mouth.
• Consumption of alcohol in excess can also increase your risk. If you drink alcohol regularly, you have an elevated risk of getting oral cancer. Alcohol abuse (more than 21 drinks in one week) is the second largest risk factor for the development of oral cancer, according to the Oral Cancer Foundation.
• Excessive sun exposure. People who spend lots of time outdoors and do not use proper amounts of sunscreen or lip balm have a greater risk for developing lip cancer. Exposure to ultraviolet (UV) radiation from sunlight may also cause melanoma, the most serious type of skin cancer.

If you notice unusual lumps, bumps, or red or white patches in your mouth that don’t go away, sores that won’t seem to heal, persistent soreness, or pain or difficulty swallowing please consult Dr. Kari Woo and our team immediately.

Other factors that may influence your risk for developing oral cancer include:

• Age: Oral cancer is typically a disease that affects older people, usually because of their longer exposure to other risk factors. Most patients diagnosed with oral cancer are over the age of 40.
• Gender: Oral cancer strikes men twice as often as it does women.
• A history with viral infections, such as human papillomavirus (HPV)
• A diet low in fruits and vegetables

During your next visit, Dr. Kari Woo will examine your mouth for signs of oral cancer. If you have been putting off a visit to our Issaquah, WA office for your regular checkup, now is an excellent time to schedule one. Regular visits can be the first line of defense against oral cancer because we can identify early warning signs of the disease. Give us a call today!

Sometime around the late teens or early twenties, people’s wisdom teeth start to erupt. These are the third and final set of molars. When wisdom teeth come in properly — meaning they are correctly aligned — they offer more chewing power. Unfortunately, more often than not, wisdom teeth are misaligned, crowd other teeth, and need to be removed.

Why do we have wisdom teeth?

It is thought that we have wisdom teeth because — back in the day — we ate a diet that consisted of more rough foods, like roots, leaves, and meat, all of which required more heavy-duty chewing power.

Reasons Wisdom Teeth Need to be Removed

While there is no clear-cut rule that says every single person needs to have their wisdom teeth removed, there are certain situations where one or more wisdom teeth are causing a problem or have a strong likelihood that problems will eventually arise in the future that warrant their removal.

1. Fully Impacted Wisdom Teeth

When a wisdom tooth is “impacted”, it means that the tooth is covered by gum tissue, thereby preventing it from erupting through the gum. This often occurs when the mouth is too small to allow enough room for the tooth to emerge. Because bacteria, food, or other mouth substances can be lodged under the gum that covers the wisdom tooth, it can lead to an acute abscess, known as pericoronitis.

2. Partially Impacted Wisdom Teeth

When a wisdom tooth is partially impacted, meaning the tooth is partially emerged from the gums, it almost always is advised to be removed. Because of its location in the very back of the mouth, a partially erupted wisdom tooth is more susceptible to not only decay and cavities, but also gum disease.

3. Other Reasons to Have Wisdom Teeth Removed

If you experience any of the below dental issues or changes in your dental health, removal of your wisdom tooth (teeth) may be necessary:

• Pain at or surrounding the wisdom tooth site, including the jaw or cheek area
• Repetitive infections
• Gum disease
• Tooth decay (extensive)
• Tumors
• Cysts
• Damage to surrounding teeth

It is important to know that the decision to have a wisdom tooth removed isn’t always cut and dry. It is essential to talk to Dr. Kari Woo about the alignment of your wisdom teeth if they have already erupted, health of your wisdom teeth if impacted or partially impacted, and your overall dental health to determine what is best for your situation.

When acids are allowed to erode tooth enamel long enough to leach calcium and other minerals from your enamel and dentin, a process called demineralization occurs. This rapidly leads to tooth decay unless reversed by good oral hygiene and professional dental cleanings at our Issaquah, WA office. Acids responsible for tooth decay come from the wastes of mutans streptococci and lactobacilli bacteria that thrive in dental plaque, a substance that is the leading cause of periodontitis.

Where do demineralizing acids come from?

Dietary sugars comprise the bulk of tooth-decaying acids, including table sugar, cooked starches, fructose, glucose, and lactose. In fact, as soon as you bite down on a sugary cookie or into a French fry, bacteria start digesting sugars, breaking them down and eventually excreting them as demineralizing acids. As this bacteria colony grows and becomes organized, plaque develops and forms that tough, yellowish coating you often see on the tops of teeth at the gumline.

Plaque is the Problem

Dental plaque is a filmy type of nesting place for bacteria that also keeps acids pressed against tooth enamel. Since plaque cannot be removed by brushing, it is important that a person who suffers tooth decay visit Kari Woo, DDS immediately so we can use special tools to scrape and thoroughly clean teeth.

Signs of Tooth Decay

Early tooth decay and cavities remain asymptomatic until demineralization creates a hole deep enough to reach the tooth’s inner tissues and nerve endings. Eventually, tooth decay will cause tooth sensitivity, toothache, vague pain when biting down on the affected tooth, and possibly pus seeping around a tooth’s gum line if the decay creates an infection. If treatment is delayed long enough, a decaying tooth may loosen, crumble, and ultimately fall out, which leaves an empty or partially empty socket.

Preventing Tooth Decay

Getting regular checkups with Dr. Kari Woo, brushing and flossing twice a day, and eating fruits or crunchy vegetables at snack time instead of a candy bar or doughnut are the three best ways to keep your teeth healthy, white, and where they should be: in your mouth.
