Dental FAQ

Woman with many dental questions at Nancy Shiba, DDS.General, family, and restorative dentistry all involve a lot of different aspects about our teeth, gums, mouth, and jaw. When you come in for a dental exam, you may have questions about the different aspects of these fields of dentistry, or about something in particular that you are experiencing inside of your mouth. At Nancy Shiba, DDS we are here to help address all of your dental needs and concerns. Below are a few of our most frequently asked questions by our patients.

Gum Disease

What is Gum Disease?

Gum disease occurs when the bacteria that builds up in your mouth begins to build up on the surfaces of the roots of your teeth. These bacteria infect your gums the same way it infects your teeth and causes them to be tender and bleed easily.

What Are the Symptoms of Gum Disease?

It can be hard to know if you have gum disease because there are often no symptoms, unless you start to experience pain or sensitivity in your teeth and gums. That is why it is important to have regular dental exams and cleanings, so the dentist can monitor any changes to your teeth and gums over time.

Is Gum Disease Dangerous?

Gum disease is the leading cause of tooth loss in the United States. The disease is the result of the harmful bacteria found in plaque. If plaque and tartar build up around the teeth, our immune system produces toxins that also target healthy tissues, causing the infection known as gum disease.

Teeth Whitening

Why Do Our Teeth Get Stained?

It turns out that there are actually two ways that your teeth become discolored, and they can have very different consequences for your smile. Extrinsic stains are the kind that we are all familiar with. These stains sit on the surface of your enamel, so with a little bit of brushing and a high-quality whitening toothpaste you can remove them easily on your own. Unfortunately, not all stains are quite so easy to remove. In fact, some stains cannot be removed at all with brushing and toothpaste, no matter how hard you try. These are known as intrinsic stains, which penetrate past the enamel. When you come in for a professional whitening service, these intrinsic stains are most of what we remove.

Is Teeth Whitening Safe?

Many of our patients ask us about how safe whitening really is. The truth is — extremely safe! We would never perform any treatment that does not have a long history of safe administration based on peer-reviewed research. Our whitening treatments are so gentle that few patients even report sensitive teeth afterward.

Are All Tooth Whitening Products the Same?

Of course, not all whitening treatments are the same. While our professional services are quite safe, the same cannot necessarily be said for the kits that you can buy at the store. Charcoal treatments erase stains by eroding your enamel, while other techniques damage the gums by bleaching or even burning them. Needless to say, this is not something we do!

Dental Implants

What is Implant Dentistry?

Implant dentistry is using an implant for teeth replacement. The implant itself, which is made of titanium, is surgically fixed into the jawbone. After placement, it is left to heal for several months. The titanium implant fuses with the jawbone in a process called osseointegration. This implant then acts as the root of the missing teeth, and over this implant, a crown or a bridge is placed that becomes the replacement tooth.

Who is a Candidate for Dental Implants?

The most important aspect that we must consider before determining whether you can be a candidate for implant dentistry is the reason for your missing teeth. Tooth loss is often the result of periodontal disease, and this will need to be treated before any other treatment or surgery can be recommended. The overall health and the lifestyle of the patient matter when looking into treatment options. Good health and habits determine the best course of action in your teeth replacement journey. We may ask smokers to quit smoking before we can consider an implant, as smoking greatly slows the healing process. We may also recommend that you maintain good oral hygiene and schedule routine check-ups.

How Long is the Dental Implant Process?

One of the requirements required from patients seeking implant dentistry is patience. The entire process may take several months from start to finish, and the patient needs to follow our recommendations to fully recover.

Porcelain Veneers

What Are Veneers?

Dеntаl veneers are also commonly rеfеrrеd tо аѕ роrсеlаіn veneers. Thеѕе are porcelain ѕhеllѕ thаt аrе bonded tо thе front of the teeth to improve the cosmetic appearance of your teeth.
