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.

Do I Need an Extreme Makeover? Why Do My Dental Crowns Look Fake?

The most common complaint associated with crowns is that they look "opaque," "lifeless," and "fake" compared to natural teeth. Do you need an expensive dental makeover to solve the problem? No!

The appearance of a crown is affected by many factors, but ultimately, the final result is determined by how the crown reacts with light. Natural teeth have a high degree of translucency, which means a certain amount of light passes through the tooth. The result of this is that the tooth appears to have depth and vitality.

Porcelain Dental Crowns With a Metal Substructure

Traditionally, crowns are made of two materials:

• porcelain, which gives it the tooth-colored appearance
• metal substructure, which gives the crown its strength

Generally, it is this type of crown that can appear opaque. The reason for this is that while porcelain is very translucent and lets light travel easily through it, no light can pass through the underlying metal. In order to prevent the metal color from showing through the porcelain, which would make the crown seem dark or gray, the metal has to be "masked out" with an opaquing material. It is this masking or opaquing that can affect the final appearance, giving rise to the opaque or lifeless look.

Do All Porcelain Crowns With a Metal Substructure Appear Lifeless?

The answer is no. One thing that can be done to improve the appearance is to remove the metal margin that goes around the crown. By keeping the metal inside the crown and having porcelain at the junction between the crown and the tooth, the "black line" appearance at the gum line can be eliminated, thereby increasing the translucency in this area. It also is necessary to have an adequate thickness of porcelain over the metal substructure. If the metal that has been masked out is too close to the outer surface of the crown, the appearance of depth is lost. What it mostly comes down to, however, is the skill level and artistry of the technician who is making the crown. When done correctly, porcelain crowns with a metal substructure can give you the best of both worlds without the expense of an extreme makeover. They can be made to exactly match your other teeth while still appearing lifelike, and since there is metal in it, they have increased strength.

Dental Crowns

Today, there are dental crowns available that do not require a metal substructure and are made of only porcelain. Depending on the specific type, they get their strength either from the bond to the remaining tooth structure or from a dense tooth colored substructure. Since there is no metal, these types of dental crowns allow more light to pass through, which enables them to have more depth and vitality, much like natural teeth. So why isn't this type of crown used all the time? The main reason is that they are not as strong as crowns with a metal substructure. So, if a person grinds their teeth, these crowns have a greater risk of fracture. Another reason why an all-ceramic dental crown cannot be used in all situations is if the underlying tooth structure itself is dark. Very dark teeth are difficult to mask with these types of crowns because of their translucency. In these instances, the dark color may show through the crown. So, for situations where a lot of force will be placed on the teeth (such as grinding habits) or if a tooth is really dark, a well-made porcelain crown with a metal substructure may be a better restoration.
