What affects the cost of dental fillings?

thousandoaksfamilydentistry.com

If you've ever looked at an invoice after dental treatment, you may have noticed that the cost of dental fillings varies from tooth to tooth. In general, the billing prices of fillings are affected by three factors: the material, the location of the tooth in the mouth and the number of surfaces to be filled. Read on to learn how and why the different rates are calculated!

All dental procedures are categorized using the Current Dental Terminology codes, which are maintained by the American Dental Association. These codes allow standardization of information between dental offices, patients and insurance agencies. In regards to dental fillings, these codes can specify the location, surfaces and material used for the restoration. Generally, the number of surfaces to be filled has the biggest impact on final cost. A filling that requires three surfaces is typically more challenging and time consuming than a single surface restoration. This does not account for the size or depth of the cavity to be filled, but merely the number of tooth walls that are to be repaired. The type of dental fillings also affects the price. Materials that are more difficult to place (such as tooth colored "composite" fillings) are typically charged at a somewhat higher rate than others. Finally, the location in the mouth has some affect on filling prices. Fillings towards the back of the mouth tend to be larger and more difficult to place, and thus are coded at a higher rate. 

At Thousand Oaks Family Dentistry, we maintain treatment rates that are on-average with the Thousand Oaks area. However, we must urge against the pitfalls of choosing a dentist based on prices alone. You should choose an office that fits best with you and your family's specific needs.

Stimulating Stem Cells With Dental Fillings

Stimulating Stem Cells With Dental Fillings

You have probably seen headlines across the internet discussing new a newly invented dental filling that stimulates stem cells within the teeth. Researchers at The University of Nottingham and Harvard University came together and created this material that is proposed to change the face of dentistry. While this discovery has huge implications for dental care, many articles oversell its proposed abilities. 

In discussing how this material is supposed to work, it is important to understand the anatomic structure of teeth. Every tooth has three general layers: enamel, dentin and pulp tissue. The enamel is mostly mineral and happens to be the hardest structure in the human body. It is also the layer most resistant to tooth decay. Beneath the enamel lies the softer and porous inner dentin. The pulp tissue is the innermost layer that contains nerves, blood supply and stem cells. These new fillings rely on changing the pulp's response to trauma and inflammation. 

Unfortunately, dental pulp tissue is not very resilient. Trauma, extreme temperatures, deep fillings and bacteria can all cause the pulp to become inflamed and/or die, necessitating a root canal. However, if the attack is moving slowly enough, the pulp may shrink itself by laying down new dentin and "move away" from the irritating source. The new filling material hopes to capitalize on this mechanism when placing deep fillings near the pulp tissue. Instead of causing the nerve to die, the substance hopes to induce the tooth to lay down more dentin, creating a safe and natural barrier between the tooth and filling. 

It is important to understand that (by design) this material is not an end-all solution to cavities and root canals. For starters, it would have little benefit over traditional fillings when used in shallow cavities far from the pulp. It would also not be of use in teeth that need root canals due to fracture, trauma or decay that extends entirely to the pulp. Many times, teeth need root canals not due to deep fillings that aggravate the pulp tissues, but rather because the bacteria have travelled through the enamel and dentin and have infected the inner tooth. Once the pulp comes in contact with outside microbes, it will almost certainly need a complete root canal treatment. 

Still, this new material has wonderful applications in the modern dental office. Many fillings that were previously given with a questionable prognosis can now be provided with increased likelihood of success. Likewise, this invention paves the road for future regenerative dental technologies. Who knows what the future holds in store!

Case Presentation: Polishing an Existing Filling

Case Presentation: Polishing an Existing Filling

Over time, dental fillings tend to pick up stains from the foods and beverages we consume. This isn't a big concern with the posterior teeth, where restorations are generally hidden during daily activities. However, discoloration can become a  genuine cosmetic concern in fillings on anterior teeth.

This patient had a filling placed years ago by a different dentist to correct for abfraction, or the loss of enamel near the gum line due to stress and clenching. This type of restoration is very common and usually affects the canines and premolars (both visible in a typical smile). They were dissatisfied with the dark line around the filling that drew the eye towards that tooth. With a 10 minute appointment to polish and recontour, the filling looked brand new! 

It is important to note that we checked the seal and fit of the filling first, to make sure we weren't just polishing a defective restoration. Many times, discoloration is a sign of recurrent decay, where the entire fillings needs to be replaced. If you would like to know more about fillings, their lifespans and how to care for them, please give our office a call!

Fillings on Decayed Teeth

Fillings on Decayed Teeth

            Tooth decay (also known as caries within our profession) is a condition that affects over 90% of adults in some degree. It is the most prevalent dental condition in the United States and likewise fillings on decayed teeth are the most commonly performed procedures in most dental offices.

 Decay follows two simple equations-

Food + Bacteria + Time = Acid

Acid + Healthy Teeth + Time = Tooth Decay.

          When the decay is shallow, it sits in the top layer of the teeth, called the enamel. Once it progresses beyond the enamel, it reaches the inner layer, called the dentin. Once decay progresses into the dentin (or very deep into the enamel), it becomes problematic and must be treated.

Once the decay progresses past the enamel, it becomes problematic and possibly painful. 

            Some decay can be spotted visually or identified using a tool called an explorer. However, most decay (and the depth of ALL decay) must be identified and confirmed using dental x-rays.  Since x-rays work by showing relative densities, decay will appear as a dark (less dense) spot against light (more dense) teeth.

            Once decay is identified, it can typically be treated by performing a standard dental filling. In our office, a variety of technologies and techniques make this as quick and pain free as possible. We start by getting you numb using a syringeless anesthetic delivery system known as The Wand. From there, a combination bite block and suction called an Isolite is used to keep the area clean, dry and protected while we work in your mouth. Decay is removed quickly and completely, using a combination of electric handpieces (commonly known as “drills” although they do not perform a drilling motion), and diamond tipped burs (analogous to a “drillbit”).

            Once the tooth is “prepared” (cleared of all decay and shaped properly), we begin the actual filing process. At Thousand Oaks Family Dentistry, we utilize the most advanced composite materials for longevity, esthetics and speed of use. The composites we use match or surpass the durability of silver fillings, and thus we only place tooth colored (nonmetal) fillings.

          In fact, we use four different composite filling systems matched to one of three bonding systems in an entire spectrum of tooth colored shades to address a variety of concerns. We firmly believe that there is no one-size-fits-all approach to dentistry, and will curtail our process to each individual person.

         After the teeth are filled, we will give the tooth an anatomically correct shape using a “finishing bur.” After that, we adjust the filling using contact (biting) paper, polishing disks and polishing burs to make sure it looks and feels outstanding. Our ultimate goal with any filling is that you cannot tell where the filling stops and your natural tooth begins!
