What are Teeth? | Indianapolis Cosmetic Dentist

Teeth, , , , , ,

186932212Your teeth outside of your oral care routine are probably not something you think about in depth. Teeth are actually complicated structures.

So we all know the proper care for our teeth, but what IS a tooth? Most of us have 32 teeth – hard, calcified white objects we use to chew, cut, crush, and swallow food.

The visible surface of the tooth is known as enamel. A hard, mineral surface, the enamel is typically light yellow to white in color, but is semi translucent, so the actual color of your tooth is determined by both the enamel and the underlying dentin. Made of a crystalized calcium phosphate known as hydroxyapatite, the enamel is both incredibly strong and incredibly brittle.

While enamel covers to outside of the tooth above the gum line, below the gum line the surface of the tooth is covered in a substance known as cementum. A yellowish substance, it contains less than half of the mineral content as enamel, making it much softer. The primary purpose of cementum is to provide a surface to allow the periodontal ligaments in the gums to hold onto the tooth.

Below the enamel and cementum lies the dentin. Dentin is a combination of mineralized hydroxyapatite, organic material and water, and is both much softer than enamel and much less brittle. However, it’s also more prone to decay, and severe cavities can cause significant dental problems if not treated rapidly.

Finally, within the dentin lies the tooth pulp. The pulp is soft tissue, filled with blood vessels and nerves that provide the tooth with oxygen, nutrients, and also the ability to transmit ‘senses’ such as temperature, pain, and pressure. The pulp also helps to form and repair dentin from within the tooth.

While most people will only see the enamel surface of their teeth, proper dental care will focus on maintaining each layer healthy. By protecting the enamel with proper brushing, and treating cavities formed by decay before they damage the dentin or pulp, dental care will focus on providing a patient with healthy teeth – from pulp to enamel – well into old age.

Dental Crowns & Bridges | Indianapolis Cosmetic Dentist

Bridges, Cosmetic Dentistry, Crowns, , , , , , ,

teeth whiteningAre you in need of dental work and wonder what types of options you will have when planning dental procedures. If a tooth has a very large area of decay, can it be saved? What happens if the tooth is cracked through the middle? If the pulp of the tooth can be felt prior to going to the dentist, does that mean the entire tooth needs to be removed?

While the best answer to these questions will come from your dentist, two likely options that will be presented are crowns and bridges.

Dental crowns are often chosen when the original tooth is compromised – either weakened from decay, broken, or otherwise unable to maintain itself without assistance. Dental crowns are custom-made – molded to match your existing tooth and fit your normal bite – out of a variety of strong materials such as steel, resin, and porcelain. Like the name suggests, a crown is a shell that goes on top of the rest of the tooth – like a hat on a head, the crown fits snugly atop the base of the tooth, providing an artificial bite surface that is stronger and harder than the natural tooth.

Unlike dental crowns, dental bridges are used in cases where the underlying tooth can not be saved. Where a crown is affixed to a single tooth to provide strength, a dental bridge is used when the tooth in question must be fully removed. Like a crown, it will be designed by your dentist to match your existing teeth and bite, and then constructed in a lab. Unlike a crown, it will not sit atop a single tooth, but is generally attached to neighboring teeth (usually one tooth on each side of the removed tooth), providing a fake tooth surface where the missing tooth would have been.

While crowns and bridges are typically only presented as options for patients with significant damage to one or more teeth, they are fairly common. Bridges and crowns are typically recommended as necessities, and as such, insurance will likely cover a portion of the cost. With proper care, bridges and crowns can last 5-15 years, or more, and will allow the patient to chew, drink and speak normally for many years.

Foods to Avoid for a Healthy Mouth | Indianapolis Cosmetic Dentist

Oral Health, , ,

multiple smilesMost people probably don’t look forward to their biannual rendezvous at the dentist’s. But the discomfort from the poking and scraping of routine cleanings is nothing compared to the pain of more intensive procedures, like fillings and root canals. So wouldn’t it be nice to seriously lower your chances of needing dental work with some strategic eating?

There are plenty of foods that people should be avoiding if they want to keep their teeth in good shape. But what’s not in your dentists kitchen?

Soda (even diet):

Your favorite sugary soda is a total smile saboteur.

Hard Candy:

Savoring a sweet sucker might seem innocent enough, but not so fast. Sucking these candies exposes your mouth to harsh sugars for longer periods of time. And chewing on them can break or crack teeth, fillings, and sealants.

Ice:

Sure, ice is sugar-free—but if you tend to chew on the cubes once you’ve finished a beverage, they can cause major damage. Dental experts say nibbling on ice is a major no-no as it can easily crack or break teeth.

White Wine:

Sorry chardonnay fans. While the deep color of red wine can cause discoloration, white wine might actually trigger even more damage. The acidity in wine makes teeth more susceptible to stains, and white wine is generally more acidic.

Chewy Candy:

That dentists avoid taffy and caramels like the plague isn’t exactly surprising. Sticky candies get stuck between braces and teeth, allowing plaque to build up. Plus, a chewy candy in the wrong place at the wrong time can easily take a tooth out.

PB&J:

Noshing a pb&j is reminiscent of childhood, but it’s a surefire way to prematurely age your teeth. The high sugar content of all three ingredients means that as soon as you bite in, enamel-eroding bacteria go on a feeding frenzy. And because peanut butter and jelly are both sticky, they allow the bacteria to adhere to your teeth.

Dried Fruit:

Things like raisins, figs, and dried apricots are bursting with nutrition. Unfortunately, they’re also packed with a dense dose of sugar and non-soluble cellulose fiber, which can bind and trap those sugars around the tooth to the same extent as saltwater taffy. Your best bet? Sticking with the fresh version as much as possible(Source: prevention.com).

Keep your smile healthy with proper oral care and diet!
