Highest Standards

We screen for early detection of oral problems

Current research indicates that problems with your mouth can affect your overall health. The opposite also is very true. It is important to detect dental problems early so that your mouth and your entire body remain healthy.

Periodontal (gum) disease affects three out of four adults at some time in their lives. It doesn't necessarily hurt and you may not even be aware you have it until an advanced stage. Regular dental visits every 6 months are essential for detecting periodontal disease at an early stage, before gums and the supporting bone are irreversibly damaged. We will screen your mouth for signs of periodontal disease every time you visit our office for an oral examination and prophylaxis (teeth cleaning).

During your exam, we also will screen for pre-cancerous changes in your oral tissues, head and neck. Cancer detected at an early stage can be more successfully treated. We will check your head, neck, and oral tissues for lumps, masses, growths, red or white patches, and recurring sore areas.

We will also screen your teeth for signs of tooth decay, examine your bite to make sure that you can chew properly, and check your temporomandibular (jaw) joints for signs of problems.

Digital dental radiographs (X-rays) are usually taken every 6 months as part of your exam. Among other things, dental radiographs can help to assess tooth decay and periodontal disease. In children, radiographs are also used to evaluate growth and development of the mouth.

As a part of your visit, we'll teach you the best way to keep your mouth healthy. We will review your brushing and flossing techniques, discuss good dietary habits, and may suggest additional tools to help keep your mouth clean. Keeping your teeth clean is the most important thing that you can do to prevent tooth decay and periodontal disease.

We stay up- to- date with cosmetic advances in dentistry

While we are primarily concerned about your oral health, we understand the way your teeth look is also very important. With dentistry's many advances, you no longer have to settle for chipped, stained, or misshapen teeth. You now have choices that can help you smile with confidence. These smile-enhancing treatments may be much more comfortable, less time-consuming, and more affordable that you realize.

We'll put your needs and wishes first and advise you on the best long-term preventative plan for healthy, attractive teeth.

  • Implant dentistry is the most advanced theraphy available to replace missing teeth.
  • An alternative to dentures or bridgework for replacing teeth. Implants more closely mimick natural teeth in appearance, feel, and function than bridge work.
  • Dental implants may offer you important advantages compared to other treatment options: improved dental health, enhanced appearance, greater self-confidence and better quality of life.
  • When your treatment is complete, you should be able to chew, speak and socialize without experiencing the negative emotions that having a missing tooth can sometimes cause.
  • Also, a dental implant will help minimize the amount of bone that will be lost in the area of the missing tooth. Preserving oral bone may help maintain your remaining natural teeth and natural facial contours. Replacing your missing tooth may reduce the risk of having poorer nutritional habits often found in patients who do not replace missing teeth.
