Restorative Dentistry for Natural-Looking Tooth Restoration

In dental materials, composite resins are just about the most exciting thing to come down the pike in a long while. Resins may well symbolize the value of long-term, persistent research. From humble beginnings in 1956, the search for an effective adhesive dental filling has culminated in resin materials - versatile, relatively strong, with cosmetic superiority. Quite a return from plastic mixed with glass beads and such.

What's amazing about filling a tooth with resin (vs. gold or silver amalgams) is the nature of the bond to the tooth. The enamel is first treated with a mild acid to create microscopic pores on the surface of the tooth. Once the resin is applied, a mechanical - not chemical - bond is formed. Sort of like dental velcro. Then the resin can be sculpted, tinted, and polished to look like the real thing.

So what do composite resins mean for cosmetic dentist patients? Let's count the ways.

Pit and fissure sealants

The best bargain in cosmetic dentistry, and proven cavity fighters to boot, are pit and fissure sealants. Sealants are a composite resin painted on back teeth, where tooth decay typically occurs in children. One sealant session, with check-ups now and then, provides cavity prevention - indefinitely.

Tooth bonding

Dental bonding is an umbrella term for placing composite resin restorations, from tooth-colored inlays to reshaping chipped teeth. For the right candidate, bonding is a comfortable, quick alternative to dental crowns, and a real boon to simple cosmetic dental care procedures. Less of your healthy tooth is removed, so it's essentially a conservative tooth restoration procedure.

Protecting exposed roots

In adults, a receding gum can expose the roots of teeth, an uncomfortable situation at best. Along with other adhesives, we apply resins directly to the root surface to help prevent tooth decay, and make the teeth less sensitive to hot and cold.

Orthodontic appliances

Teeth straightening just became easier. We can use resins to bond braces directly to teeth, so heavy bands around teeth, in some cases, can be dispensed with. The new invisible braces, along with bonding, make adult orthodontics an appealing alternative to crooked teeth.

Move over, amalgam

Well, not really. Composite resins may never replace old standby filling materials, especially on back teeth. But resins have taken their rightful place in cosmetic dentistry, complimenting metal amalgams, and they can only get better.

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.
