Why do I need to go to the dentist regularly?

Six months is about the length of time that tartar forms and begins to make its inexorable move under your gumline. No matter how good a brusher and flosser you are, everyone forms some degree of tartar in areas such as the inside of the bottom incisors. When we see you every six months, we also are able to see signs of oral cancer or gum disease before they really take over. Plus, if we catch decay in a tooth early, it's much easier to remove and fill.

How can I prevent cavities?

The basics of good home oral hygiene are usually sufficient to prevent most cavities from forming. When you brush and floss, you remove the plaque, which immediately starts forming again. That's why you need to brush twice daily and floss once a day. You can also help your teeth out by eating and drinking fewer sugary foods and beverages.

If you don't floss between your teeth, plaque gathers and builds there. You may be the best tooth brusher on the planet, but your toothbrush can't get to all of the tooth surface between your teeth. Flossing scrapes away the plaque between your teeth and under the edges of your gums, preventing the start of tooth decay and gum disease.

Why do I need to have X-rays taken?

X-rays are an important diagnostic tool because they allow us to find cavities, look at the tooth roots, determine if your gum disease has affected the jawbone, see developing teeth, track the path of descending wisdom teeth, check all the bony areas of the mouth, and monitor the alignment of your teeth.

What is fluoride and why is it important for dental health?

Fluoride has been proven in dozens of studies to strengthen teeth, even reversing decay in early stages, and to strengthen our bones. Fluoride strengthens your teeth by fighting demineralization. It helps prevent tooth decay by making the tooth enamel more resistant to acids from bacteria and sugars in the mouth.

What can I do about sensitive teeth?

The first step in addressing tooth sensitivity is to come see us at Centennial Dental. We will get to the cause of your tooth sensitivity, and we may place a filling, perform a root canal, place a crown over a fractured tooth, apply fluoride varnish, or cover exposed root surfaces with sealant to protect them.

Do I still need to see the dentist if I have dentures?

Yes. Your oral health isn't just your teeth; it includes your gums and jawbone. As a denture wearer, when you come in to see us at Centennial Dental, we check the changes in your gums and jawbone. We'll check the fit of your dentures, look for sore spots, adjust the fit to alleviate them, and check for oral cancer.

 Trustindex verifies that the original source of the review is Google. Dr. Koeltl and his staff are friendly, so caring and provide excellent care for my teeth.  Recently Dr. Koeltl kept pursuing dryness in my mouth during sleep (potential gum disease) and provided me with options to fix it.  A simple piece of tape to keep my mouth shut during sleep fixed the problem.  My hygienist does a great job each visit cleaning my teeth.
