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.

Your Dental Makeover: Discover How Plastic Surgery Relates To Cosmetic Dentistry

Cosmetic dentistry and plastic surgery both blend health care with artistry and beautification. However, before we can beautify a person's smile, we must have a complete understanding of your dental makeover, not just an appreciation of, beauty.

Some of the first people to understand beauty were not health care specialists, but rather, artists. Great painters and sculptors studied anatomy, perspective, illusion, proportion, idealism and symmetry in order to recreate the beauty they saw.

Esthetic surgeons and cosmetic dentists create better-looking smiles. A cosmetic dentist creates pleasing-looking teeth, while the surgeon helps you feel more like smiling.

If cosmetic dentists and esthetic surgeons want to create beautiful smiles, they must begin to think like the great dental makeover artists. Michelangelo would never have considered one of his masterpieces complete until it was framed properly. The same goes for cosmetic dentistry. If we think of the teeth as the masterpiece, the frame is the surrounding soft tissue (such as the gums, jawbones, facial muscles, lips, and skin). We cannot consider one without the other.

Let's look at the areas of the face that contribute to the smile.

The Lips Form the Smile

The support of the lips is very important. If the teeth are properly contoured and there is a normal bite, the lip support is nearly always adequate. When it is inadequate, it is correctable.

Aside from the teeth, the chin also plays a role in the shape of the lips. A weak chin can give lips a protruded appearance. The solution is to increase the fullness of the chin through cosmetic plastic surgery.

The Mouth Is the Center of the Smile

The next area of cosmetic dentistry focus in your dental makeover is the shape of the mouth. The lips and the teeth are of primary importance to the support of the lips; however, the facial muscles of expression are what control the smile.

When the corners of the mouth are either turned up or down, they convey the feeling of happiness or sadness. Soft tissue corrections around the mouth should be corrected after the teeth and jawbones are corrected.

Other facial features that can be surgically altered to contribute to a terrific smile are:

• The nose may shadow the smile; The nose helps to proportion the smile in how it relates to the mouth and cheeks.
• The chin aids in determining facial balance; A prominent or deficient chin can affect facial symmetry.
• The jaws help shape the face and smile; A deficient upper or lower jaw can divert attention away from the smile and lay focus on the deficiency.
• The cheeks lift the corner of the smile; Sagging facial tissue that hides nicely-shaped lips, cheeks, and jawbones can be "lifted" to once again feature a pleasing smile.
• The brows and lids usually contribute greatly to the smile; thick upper eyelids that make people look tired or sad can be thinned.
• The skin may be wrinkled by smiling or frowning; Small facial muscles placing tension on the skin sometimes cause fine aging lines. They can be corrected through chemical peels, Botox injections, dermabrasion or a combination of these along with a facelift.

For further information on your dental makeover, consult with a cosmetic dentist, dermatologist or plastic surgeon. Each of these specialists works in close relationship with each other and can further counsel you on the best cosmetic dentistry treatment to improve your smile.
