composites and sealants. BPA exhibits hormone-like (estrogen) properties that raise concern about its suitability in consumer products and food containers. Some laboratory testing has suggested that BPA may effect reproduction and development in animals by mimicking the effects of the female hormone estrogen. This testing is raising concerns about its safety.

Health Effects Of BPA

BPA is thought to  mimic a form of estrogen, called estradiol, and may lead to negative health effects. The earlier the exposure, greater the sensitivity to its effects. Some studies have linked prenatal exposure to later physical and neurological difficulties. The FDA have determined safety levels for humans, but those safety levels are currently being questioned or are under review as a result of newer, more in depth research  studies. A 2011 study that investigated the number of chemicals pregnant women are exposed to in the U.S. found BPA in 96% of women.

BPA and Dentistry

There are three ways BPA can become a part of dental materials:

-As a direct component from manufacturing in dental composites or dental sealants.

-As a by product of degrading dental composites or dental sealants in the mouth. Composite resins are formulated from a mixture of monomers that are commonly based on bisphenol A glycidyl methacrylate (bis-GMA). Some composite resins may contain other monomers, in addition to bis-GMA, that are added to modify the properties of the resin. An example is bisphenol A dimethacrylate (bis-DMA). Bis-DMA-containing materials can release very small quantities of BPA because bis-DMA is subject to degradation by salivary enzymes.

-As a trace material during manufacture of dental materials. BPA may be used in the production of other ingredients found in some dental composites and sealants. Bis-DMA and bis-GMA are both produced using BPA as a starting ingredient, so residual trace amounts of BPA may be present in the final product.

There are many products utilized for “white” fillings. You can ask if your dentist is BPA free. The products utilized should not contain BPA, and even better if there is also no Bis DMA.

BPA Conclusion

There have been numerous studies conducted. One of the most recent ones linked BPA to children’s behavior a few years following placement of BPA containing dental restorations. The studies showed their was some effect but it was quite small and not known if it was a direct link or not. Further studies need to be completed over the long haul, but most dentists and manufacturers are moving away from dental materials containing BPA.

There are many articles on line about the effects of exposure to BPA, posing different levels of concern. Hopefully, future research will continue with the evolution of even better products to keep us all healthier.

 

 

Dental Bonding (also referred to as Adhesive Dentistry) is the process whereby your dentist or cosmetic dentist rebuilds, reshapes, and/or covers tooth defects using tooth-colored materials (composite resins).

Chipping a tooth is one of the most common dental emergencies  that patients and dentists face. Luckily, with modern materials and techniques, it is a situation that is can very easily and quickly be fixed. If the chipped or missing area of tooth is less than about 1/3rd of the tooth surface, dental bonding can be utilized as an option to replace the missing tooth structure with a matching tooth colored material. In situations like this, the dentist can restore your tooth in as little as 45 minutes, sometimes, with no need for local anesthesia. If the chipping covers more than 1/2 of the tooth surface, dental bonding is not generally, a good long term answer. The dentist may instead, recommend a traditional crown PFM (Porcelain fused to a metal framework crown) ,an all porcelain crown or a porcelain veneer.

What is Dental Bonding?

Dental Bonding is a procedure used in cosmetic dentistry to restore a tooth after it has discolored, decayed, broken or chipped. The cosmetic dentist will use a tooth colored material called a dental composite to rebuild the tooth to its former shape,color, and size.

Steps Involved in Dental Bonding

-Preparation. Very little preparation is needed for dental bonding, especially in the case of a chipped tooth. Anesthesia is usually not even needed unless the dental bonding is needed to restore a deeply damaged or traumatized tooth, a fracture close to the nerve, a sensitive tooth, or a tooth damaged by a tooth cavity. Your dentist will need to roughen up the surface and clean the edges to prepare the area to accept the dental bonding. Your dentist will also select a color match for the composite resin they will use. This is generally done by matching to your existing tooth structure.

-The Actual Dental Bonding Process. As mentioned earlier the surface of the tooth will be roughened and an acid etch (phosphoric acid), will be applied to the tooth. The etch removes surface debris and  opens up tiny tubules to bond to. Next, a primer is applied to wet the surface and allow the adhesive  to flow into those tubules. Third, the adhesive bonding agent is applied, this  allows for the material to adhesively bond to the remaining tooth structure. The tooth-colored composite resin is then applied to the effected area, molded, and smoothed to the desired shape. A special light is then used to harden or cure the material. Once the material is hardened, your dentist will need to do more shaping and polish it to match the sheen of the rest of the tooth surface. One of the most important parts of the entire process is in the final shaping and polishing. It is important to blend the composite resin properly to get a result that looks and feels like your natural tooth structure. Once the dentist is happy with the result, they will check your bite. By checking your bite the dentist ensures that your teeth are all biting evenly and not hitting the new restoration first when biting and chewing. The correct bite will allow the bonding a better chance to last.

The entire process should take anywhere between 30-60 minutes depending on size of chip. If done properly, dental bonding should not be noticeable to anyone. It should match your existing tooth structure perfectly.

Dental Bonding – Chipped Front Tooth

Advantages of Dental Bonding

-Dental bonding is probably one of the most fulfilling cosmetic dentistry procedures to perform.

-Dental bonding can be completed in office in one short visit. As opposed to a porcelain crown or porcelain veneer which take 1-2 hours . Crowns and veneers take multiple visits to complete and need a dental laboratory to custom fabricate the porcelain crown or porcelain veneer.

-Local Anesthesia is usually not needed unless there is trauma or tooth decay involved.

Disadvantages of Dental Bonding

-Dental bonding can stain over time

-Dental Bonding can break down over time. It is not as strong as an all porcelain crown or even a porcelain veneer.

-Dental Bonding can chip just like a natural tooth. Precautions need to be taken when eating and chewing.

Dental Bonding – Replacing older Metal Restorations

 

Dental bonding is an effective and cost effective way to repair and reshape damaged teeth. If you think you may need dental bonding, your dentist can let you know if this procedure is a good option for you.

White fillings are a dental restorative material used to restore function, integrity and morphology of missing tooth structure. The missing tooth structure can occur from cavities, external trauma, and also lost intentionally via preparation of the tooth by the dentist for the dental filling. The development of tooth colored or white fillings has provided the cosmetic dentist and patients with a far more cosmetic alternative to traditional metal fillings.

Because the white fillings can be blended and mixed, a skilled cosmetic dentist is able to precisely match the tooth color of the fillings with the natural color of your teeth. Thus, they are able to place fillings that are virtually undetectable. This means only you and your dentist will know you have these fillings. These fillings are commonly called composite resins after their ingredients. These resins are metal free and are composed of a variety of materials. The most popular ingredients include acrylic resin and powdered particles similar to glass.

Tooth colored white fillings are done in one visit, in a procedure much like that for metal amalgam fillings, except that a high intensity curing light is used to bond the composite material to the tooth. Most patients will select tooth-colored composite fillings when they have a new cavity. As the availability of white fillings has increased more and more patients are having their cavities filled with cosmetic tooth colored fillings.

Metal fillings do not bond with the tooth structure. They merely rested on it and provided a degree of protection but over time the margins will open causing bacteria to leak inside. This causes a new cavity to form. Decades of research has led us to know so much more about the interface Tooth Colored Fillingsbetween dentin and enamel. This has led scientists to discover new ways of bonding fillings to teeth to create a stronger, more sealed connection between filling and tooth and also to be more aesthetic.

Composite resins allow us to keep more of your natural tooth structure intact than amalgams. Most dentists believe in being as conservative as possible. The more natural tooth structure we maintain, the better teeth you will likely have in the future.

Mild sensitivity is felt by some patients following the placement of composite resin fillings. This is usually temporary in nature and resolves on its own, usually in a few days. The only caution that is usually mentioned is that coffee, tea, and other staining foods and beverages may discolor your white fillings over time. These restorations have been shown to last an average of 7-10 years. It is vital to see your dentist regularly so they can be evaluated at every visit for possible breakdown of the material or further cavity formation.

Dental bonding can provide dramatic, aesthetic results in a very short period of time, usually in one appointment. With dental bonding, we can:

-Close gaps or spaces between teeth.

-Restore decayed teeth.

-Change the contours of small, misshapen teeth.

-Repair chipped or cracked teeth.

-Cosmetic tooth color fillings.

-Replace old metal amalgam fillings with a cosmetic alternative.

-To protect an exposed root surface following recession of gums.dental bonding

Cosmetic dentists can shape and color a single tooth, or they can change your entire smile.
