Are White Fillings Harmful to Kids?

Recently, white fillings (tooth colored)  came under fire for possibly contributing to poor behavior in kids. The media has highlighted that the BPA (bispenol A) containing fillings had a small but significant correlation to behavior issues in children.  The point not highly emphasized was that the level of BPA released from whiteReno Dentist - Tooth Colored Fillings fillings in the mouth was not measured.  It is not known what, or if, any chemicals are actually being released from these fillings. “It’s generally assumed that the amounts leached are tiny”1 Children with multiple white fillings, according to this study, constantly scored up to 6 points worse on a behavior survey answered by their parents.1  Effects from BPA have been noted as being “far from clear,” even looking back to a story from Reuters late October 2011. 

Important Points to Consider about Dental Fillings:

1.  Dental caries is a preventable disease by practicing good oral hygiene habits, limiting exposure to dietary acids (citric acid) and sticky sugars (dried fruits), and keeping regular dental cleaning appointments.

2. White fillings are primarily a silicate glass which is bound by a resin containing small amounts of BPA, which levels of BPA release have not been measured.

3. Silver Amalgam fillings are an alternative to white dental fillings, but a little more tooth is removed in the preparation.  Though it is one of the most researched dental materials and deemed safe by the ADA, they contain small amounts of mercury, and these fillings have been known to discolor and darken teeth. 

4. Any concerns you may have should be discussed with your dentist.

Osteoporosis and Bisphosphonates – Bone Loss is Not Your Only Concern

Oral health is not commonly found in the forefront of everyone’s mind when we think of osteoporosis. For those at risk for osteoporosis, it should be something you not only discuss with your doctor but your dentist as well. Loss of bone in the mouth leads to loss of teeth, which makes it more difficult to properly nourish your body. There are many treatments used to address osteoporosis, but some such as Bisphosphonates severely impact you mouth. Bisphosphonates, such as Fosamax, Boniva, Actonel, and Reclast place a person at risk of developing osteonecrosis of the jaw which means a person’s gum tissue is not fully covering the bone leaving it exposed to the oral environment. This condition is difficult to treat, so if you need to be placed on Bisphosphonate treatment it would be best to see your dentist beforehand to make sure there are not any compromised teeth or teeth that need to be removed. The trauma associated with tooth extraction combined with use of bisphosphonates can lead you down the path of non-vital bone. While the exact cause is unknown, it is thought to be due to possible infection, the jaw’s limited ability to repair itself, or decreased vascularity of the jaw. Bisphosphonates reduce your bone’s ability to turn over so the constant production of bone reduces the blood supply due to the increased bone density. Recently it has been noted that use of bisphosphonates may increase a person’s risk of dental implant failure. A study conducted at the New York College of Dentistry found that women with dental implant failure were about 3 time more likely if they were taking oral bisphosphonates. Managing osteoporosis is a team effort and you should be seen by your dentist on a regular basis to preserve your oral health.

Tooth pain: Don’t wait till it is too Late

All too often, we see patients that have had some sensitivity and ignore it until the tooth pain keeps them from sleeping or functioning in their daily life. Tooth pain can mean several things such as deep cavity, a cracked tooth, clenching or grinding, periodontal disease, a sinus infection, and impacted wisdom teeth. Each source of tooth pain has a different treatment to correct the discomfort. The focus of this posting is the progression of decay, when it should be treated, and the more extensive treatment required to save the tooth if it is allowed to progress.

Tooth Ache caused by a Cavity:

 Generally patients do not realize that the initial onset of tooth decay is a painless, chalky white spot. Depending on a person’s oral hygiene habits this spot can be maintained and sometimes reversed. Once the cavity spreads to the dentin the tooth decay is best treated by removing the infected tooth structure and replaced with a filling.If left untreated the tooth decay will continue to spread and often create an annoying sensitivity to cold, sweets and sometimes pressure. At this point the pulp in your tooth is inflamed from the irritation of the bacteria getting close to the pulp. Most of the time, the symptoms can be resolved by removing the tooth decay and filling the tooth. The problem with a cavity this size is the tooth is considerably weakened by the amount of infected tooth that needs to be removed. The point that too many people address the tooth pain is when the cavity reaches the pulp and there is severe sensitivity to cold or heat that lingers, pain to pressure and tapping. The lingering sensitivity to hot or cold indicates to us that your pulp is irreversibly inflamed or necrotic (dead). At this point the tooth needs all tooth decay removed an root canal therapy to clean out infected tissue and to seal the canals from the rest of the body to treat the tooth pain.

Tooth decay due to a rapid onset of dental caries.

 After the symptoms are treated we then look to restoring the tooth which commonly involves building up lost structure and placement of a crown. Every case has its own special qualities about them and it is always recommended to save what you can, but on occasion you may be faced with having to lose the tooth.
