Not everyone will need their wisdom teeth extracted, but it's a common dental procedure for many people as they reach their 20's. In fact, wisdom teethit's estimated that about 85% of people will have their wisdom teeth removed. At Arbor Hills Dental in Newburg, Oregon, Dr. Angela Toy and her team carefully evaluate each of our patients' dental health to determine the best and most beneficial treatments. If you still have your wisdom teeth, you might wonder when and if you'll need them removed. You've come to the right place to learn more!

What are wisdom teeth?

Wisdom teeth, also called third molars, are so named because they tend to come in during the early twenties, a time when you've had some real-world experience from which to gain wisdom. They are positioned at the back of your mouth and are often very large. Some anthropologists speculate that wisdom teeth were a useful part of prehistorical people's anatomy; they needed more teeth with which to chew their diet of meat and raw plants and vegetables. Over time, humans' skulls and jaws have become smaller and many do not have room for their wisdom teeth to grow in properly. This could help explain why wisdom tooth removal is so common today.

Why do wisdom teeth need to be removed?

If wisdom teeth have come in straight and complete, they may not require removal. However, this is not the case for many of your Newburg dentist's patients. Oftentimes the wisdom teeth will only come in partially, leaving spaces under the gums to trap food and lead to infection. They may even be unable to emerge at all, often causing painful cysts to develop around them. Their unusual grown patterns can also cause your other teeth to shift out of place, which could lead to crookedness or other problems. An X-ray taken during an examination can help Dr. Toy determine if wisdom tooth removal can help you.

Eliminating pain and discomfort is one of our major objectives during dental treatment. To that end, our profession has developed a number of anesthetic drugs and deliveries that ensures your experience in the dentist’s chair is as pain-free as possible.

But there’s another experience many people have with dental care that’s different from physical discomfort — emotional anxiety. These negative emotions can range from nervousness about a procedure to extreme fear. Very often the patient has no control over these emotions — they’ve become imbedded from earlier experiences or the influence of others.

Although each can influence and heighten the other, anxiety and physical discomfort are different and require a different approach. Physical pain and sensation is eliminated through anesthesia, either locally through topical application or injection or generally through intravenous medication that renders a person unconscious. Anxiety, on the other hand, requires first building a trustful relationship with an understanding dentist. But it may also call for certain drugs that sedate — promote a feeling of relaxation — rather than numb sensation.

We’ve incorporated a number of sedative medications in dentistry like Valium or Ativan that work well to reduce anxiety before and during treatment. Many are taken orally, usually just before scheduled treatment, and they dissipate from the system quickly afterward. Some medications also have “amnesic” qualities, meaning you won’t remember anything or little at all about the treatment period. This can be helpful in amassing positive treatment experiences that may diminish negative feelings you’ve developed about dental treatment.

It’s important, though, to find the right types of medication that work well for you. For that reason we’ll take a thorough medical history, including prescription or over-the-counter medications and supplements you’re taking and any medical conditions you may have. It’s also important to discuss your diet (certain foods can inhibit the action of some sedatives) as well as if you use tobacco or regularly drink alcoholic beverages.

Taken properly, oral sedation can effectively reduce your anxiety during treatment. As a result, it will be much easier and pleasant for you to receive the care you need for a healthy mouth.

If you would like more information on reducing anxiety during dental treatment, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “Oral Sedation Dentistry.”

We’ve come a long way since the early 1980s when we first identified the HIV virus. Although approximately 35 million people worldwide (including a million Americans) now have the virus, many are living relatively long and normal lives thanks to advanced antiretroviral drugs.

Still, HIV patients must remain vigilant about their health, especially their oral health. ┬áIn fact, problems with the teeth, gums and other oral structures could be a sign the virus has or is moving into the full disease stage, acquired immunodeficiency syndrome (AIDS). That’s why you or a loved one with the virus should maintain regular dental checkups or see your dentist when you notice any oral abnormalities.

One of the most common conditions among HIV-positive patients is a fungal infection called candidiasis (or “thrush”). It may appear first as deep cracks at the corners of the mouth and then appear on the tongue and roof of the mouth as red lesions. The infection may also cause creamy, white patches that leave a reddened or bleeding surface when wiped.

HIV-positive patients may also suffer from reduced salivary flow. Because saliva helps neutralize excess mouth acid after we eat as well as limit bacterial growth, its absence significantly increases the risk of dental disease. One of the most prominent for HIV-positive patients is periodontal (gum) disease, a bacterial infection normally caused by dental plaque.

While gum disease is prevalent among people in general, one particular form is of grave concern to HIV-positive patients. Necrotizing ulcerative periodontitis (NUP) is characterized by spontaneous gum bleeding, ulcerations and a foul odor. The disease itself can cause loosening and eventually loss of teeth, but it’s also notable as a sign of a patient’s deteriorating immune system. The patient should not only undergo dental treatment (including antibiotics), but also see their primary care physician for updates in treating and managing their overall symptoms.

Above all, HIV-positive patients must be extra diligent about oral hygiene, including daily brushing and flossing. Your dentist may also recommend other measures like saliva stimulators or chlorhexidine mouthrinses to reduce the growth of disease-causing bacteria. Together, you should be able to reduce the effects of HIV-induced teeth and gum problems for a healthier mouth and better quality of life.
