general and preventive dentistry

Dr. Manami Yamaguchi has been assisting dental patients for years, helping them to get the healthy, brilliant smiles that they deserve. She offers general and preventative dentistry in addition to cosmetic and restorative dental treatments because she knows that if you do not enjoy good dental health, then no cosmetic or restorative treatment is going to deliver good results. She starts from the ground up, working to make sure that you have no decay and no gum issues. To do this, she expects that you will see her for regular dental examinations, and see her friendly hygienists for ongoing cleanings. Once you have a healthy mouth, then, if you like, you can work on improving your smile.

Dental Exams

When you first visit Dr. Yamaguchi, she will do a complete dental examination in order to determine if you have any issues that should be corrected. Often, patients think that there is nothing wrong, but that is because they cannot see tooth decay in its early stages. Dr. Yamaguchi can find tooth decay before it ever has a chance to get hold. Then, she will recommend a course of treatment that will not only treat the early decay, but stop it before it has a chance to spread to adjacent teeth. Caught early, tooth decay can be halted before it begins to trouble you in later years.

Dr. Yamaguchi is also very sensitive to patients who have not seen a dentist in a long time, and who may have serious dental issues. Full mouth restorations for elderly patients are a specialty. Giving back life to patients is a high priority.

Dental X-Raysdental x-rays general and preventative dentistry

Often, aging patients are reluctant to have dental x-rays done, and it is no wonder. Not all that long ago, having dental x-rays meant having a metal plate slammed into your mouth, and being made to sit still for what seemed like forever while the images were taken. Then they had to be developed, and if they did not come out just right, the whole procedure had to be re-done.

Older patients, and younger ones as well, will appreciate that this is no longer the case. Today, dental x-rays are done digitally. The camera is very small, and will not need to go in your mouth. Usually, too, it’s taken correctly on the first try. Dr. Yamaguchi can see a clear image of what is going on in your mouth in a single shot.

Dental Cleanings

Are you afraid of dental cleanings? If you are not, then you are probably a young person who knows that much of the cleaning is done by means of ultrasound – there is very little scraping needed.

Unless your teeth have not been professionally cleaned in a long time, the ultrasound will usually be able to simply blast away the plaque and tartar without the need for any invasive procedures.

Occasionally, you may need a bit of manual scaling, but the ultrasound will typically do most of the work, so you can depart the dentist office with wonderfully clean teeth, having experienced very little, or even no, discomfort.

Dental Hygiene

Unless you have been living in a cave for the past century, you know that you have to brush your teeth and floss regularly. It is amazing, though, how many people do brush and floss, but fail to do it the right way. You might be vigilant about brushing, but not getting at the most important areas.

At Dental Arts and Wellness, our dental technicians can show you the right way to brush and floss. They can even suggest the best products for you to use.

You may know how to brush and floss properly, but still not consider the health of your gums. The fact is good oral care is not just about your teeth; it is about your gums as well. If you do not take care of your gums, then your teeth could end up decaying, become loose, and even fall out. Gum disease is actually the foremost cause of tooth loss, and nearly 80% of Americans will experience gum disease to one degree or another by the time they reach the age of 40.

Does this sound as if there is no hope? No. Remember, 20% of Americans will not develop gum disease. These are the Americans who will brush and floss as they should, get regular cleanings and checkups, and work toward good oral health. These are the people who will live all their lives with their natural teeth.

Composite Fillings

Dr. Yamaguchi is a Japanese dentist who often sees senior patients who still have metal tooth fillings. If you have metal fillings that contain mercury, Dr. Yamaguchi can remove them for you and replace them with tooth colored fillings. You will never have to worry about how much mercury your body can tolerate because there will be none at all.

Oral Cancer Screenings

Do you ever worry about the possibility of oral cancer? Probably not, unless you are a heavy drinker or a smoker. But the fact is even if you live a completely “clean” lifestyle, you can still be vulnerable to oral cancer. It can happen to anyone.
When you see Dr. Yamaguchi for a regular dental exam, she will also check you for signs of oral cancer. This will involve not just a visual screening, but an Oral ID assessment, which is a high-tech technology that can identify oral cancer in its very early stages.

You will always know when you visit Dr. Yamaguchi’s office that she will assess you for oral cancer, and order a biopsy if anything looks unusual. Most of the time, your biopsy will come back showing nothing out of the ordinary, but if it does, Dr. Yamaguchi will look after you.

Oral DNA

Dr. Yamaguchi is one of very few dentists who is authorized to perform oral DNA testing. This is a means of allowing her to treat the whole patient more effectively, and ensuring better overall wellness. With this method, a more comprehensive diagnosis is possible. It is easier to identify periodontal disease, respiratory problems, bad nutrition, and other complications. It is easier to identify adverse outcomes.
