Is Your Nose Getting Closer To Your Chin? Restorative Dentistry Can Help!

Everyone, even your dentist, knows that when we age, we see certain changes in our face (for example, wrinkled skin, less skin tone, shrunken appearance). The soft tissue in the lower one-third of the face is supported by the teeth and jawbone, and gives support to your smile. As we age, we lose support to our smile and we begin to appear older.

Anatomically, the face is divided into thirds: the upper, middle and lower one-third. The space between your nose and your chin is referred to as the lower one-third. The teeth support the vertical height of your lower face, and more specifically the back teeth support your lower face.

Most dentists agree that minimal and gradual wearing away of the top enamel of the teeth is considered normal during the lifespan of a patient. However, excessive wear on the top surfaces of the teeth can result in abscessed teeth, an irregular bite, decreased chewing capacity and esthetic disharmony. Patients with these types of problems often require extensive restorative cosmetic dentistry treatment.

How Common Is Tooth Wear?

Although the prevalence of tooth wear, or attrition, is not known, it is thought to be very common in adults over the age of 40. The wearing of the top surfaces of the teeth is most often attributed to attrition, which is the wearing away of one tooth surface by another tooth surface. Attrition is the result of bruxism, or the involuntary grinding of the teeth against each other.

How Does Attrition Occur?

Attrition can be the result of one or a combination of problems such as:

• Congenital Abnormalities: Hereditary abnormalities can cause the malformation of the surfaces of the teeth. This can result in a thin and/or brittle outer layer of the tooth. This leaves the tooth more susceptible to surface wear and a more rapid attrition of tooth structure.
• Parafunctional Habits: One type of parafunctional habit is bruxism, as explained above. Other habits often associated with attrition include biting on needles, pipe stems, pencils, or finger nails as well as clenching. Many studies have related stress to attrition.
• Abrasion: It is defined as the wearing away of tooth tissue through mechanical processes. The top surfaces of the teeth are abraded away usually by diet, chewing of abrasives such as tobacco and environmental factors such as constant exposure to dust and grit (in farming).
• Erosion: Erosion is the destruction of hard dental tissues by chemical action. Diets high in acidic content like juices, colas and other carbonated drinks are examples of the foods that cause erosion. Patients who suffer from anorexia nervosa or bulimia are prime examples of erosion due to the high acid nature of stomach acids that are constantly regurgitated into the mouth.

What Is the Result of Worn Teeth?

Depending on the severity of the tooth wear, teeth may be broken, shortened and unattractive. Having worn teeth can result in jaw joint pain (TMJ), a decreased ability to chew and a sunken appearance to the lower face. All of these results can make a person appear more wrinkled and older.

Can Worn Teeth Be Fixed with Fillings?

Generally, the worn teeth will have to have new fillings placed or redone. When severe wear occurs in the mouth, a dental crown or multiple crowns may be the only solution.

Can Tooth Wear Be Prevented?

Yes, tooth wear can be prevented, but only if you make regular visits to the dentist. If detected early enough, your dentist may prescribe a plastic night guard to protect your teeth, much like an athletic mouth guard.

What's a Temporary Dental Crown?

When you decide to have crowns done, especially if they involve your front teeth, you will want to be able to give your input regarding how the final crowns will look. One way to do this is with temporary dental crowns. When your teeth are prepared for crowns, the dentist will place temporary dental crowns for you to wear while the final crowns are being made.

What Are the Main Purposes of Temporary Dental Crowns?

• Temporary dental crowns eliminate any tooth sensitivity by achieving a seal around the tooth.
• They also can keep your gum tissue healthy by recreating the contour of your real teeth. Keeping the gum tissue healthy is of prime importance when it comes time to place the final dental crowns. If the gum tissue is not healthy when the final crown is cemented, there may be contamination of the cement, which can result in a poor bond and/or sensitivity.
• They maintain the current position of your teeth by keeping contact with the opposing teeth when you bite and by contacting the adjacent teeth. This is important because all teeth can move and even a slight amount of movement can prevent your permanent tooth crowns from fitting correctly, requiring either a lot of adjustment or having it remade.
• Finally, the temporary dental crowns should act as blueprints for the final crowns. It is during this time that you can give the dentist your input regarding the position and shape of the teeth (for example, if the teeth are too long, too short, too square, etc.).

Care of Your Temporary Dental Crowns

There are some differences between temporary dental crowns and final crowns that you should be aware of. Temporary dental crowns are made of a different material, usually some sort of a plastic or acrylic. Since these materials are not as strong as your own teeth, you will have to be careful of what you eat. You should avoid hard foods such as nuts, and tough foods such as bagels or French bread.

Another difference is that temporary dental crowns are cemented on with a dental cement. The reason for this is that the cosmetic dentist will need to be able to remove the temporary dental crowns when it is time to cement the permanent ones. Since the cement is not as strong, sticky foods may cause them to come loose.

If your temporary dental crowns come off or are loose, you should call your dentist so that they can be re-cemented. It is important not to wait, as the tooth may be sensitive, it may move, or, if a long enough period of time passes, the tooth may get decay. As far as home care, your temporary dental crowns should be cleaned with a toothbrush, just like your own teeth. When flossing, though, it is important to floss towards the gums and then slide the floss out by one end rather than lifting it back up through the teeth. This will help ensure that your temporary dental crowns do not come off while flossing.
