Beware of BPA: Found to Damage Tooth Enamel

January 12th, 2014

girl looking in the mirrorThere has been much talk about the dangers of ingesting BPA through plastic sippy cups and even water bottles that we bring on the go. BPA, also known as bisphenol A, is a chemical found in hard plastics of food and drink containers and acts in a similar way to estrogen, and other hormones in the body.

The Food and Drug Administration (FDA) had originally deemed BPA to be a safe substance, but recent studies have shown that this chemical has lead to disruption of normal hormone levels, possible brain and behavior problems in infants and young children, and an increased risk of cancer and heart problems.

Recently, researchers have tied enamel damage to early exposure to BPA. A team led by Ariane Berdal of the Universite Paris-Derot showed that rats that have been treated daily with low doses of BPA resulted in damaged enamel. The rats were observed during a 30-day development window where researchers exposed the rats to the doses of BPA. The earliest observations founds on the rats were white marks found on their incisors. On a macroscopic level, the teeth with white marks were found to have fragile and brittle BPA. On a microscopic level, the enamel showed a decreased level of crucial minerals, the teeth were more susceptible to cavities.

The damage found on the teeth of these rats is comparable to damaged tooth enamel found in 18% of children between the ages of 6 and 8. These researchers believe that enamel damage is another effect of BPA damage to the body. It is important to check products for a “BPA-free” label before they are bought. While the FDA has cracked down on plastics containing, be cautious when buying baby bottles, sippy cups, baby formula cans, and other products for young children.

I’m pregnant! But what about oral health?

July 24th, 2013

During pregnancy, women tend to look towards an overall healthier way of living. Many primarily seek out medical professionals that can keep them on track with a good diet and care for the coming baby. However, many expecting mothers tend to put oral health on the back burner during pregnancy.

 

It is highly recommended that good oral health be maintained before, during and after pregnancy. Pregnancy is known to kick start hormonal changes that can increase the risk of gum disease, which can in turn affect the coming baby. Because dental procedures have the potential of influencing the baby’s growth and development, it is recommended that mothers should avoid dental treatments during critical times for the baby, notably the first trimester and second half of the third trimester. But, routine dental care can be done on mothers in their second trimester. This also means that expecting mothers should be extra careful in keeping up with good oral hygiene during these critical stages of pregnancy.

 

It is important to keep the dentist informed of all the drugs that are taken during pregnancy; this can range from medications and even prenatal vitamins that have been prescribed. Dentists can potential modify the dental treatment plan based off of the drugs that are ingested. There are key drugs, including tetracycline, which can influence the expecting child’s teeth and should be avoided during pregnancy.

 

With these pointers in mind, it is essential to understand that being pregnant does not mean that it is a ticket out of a dental appointment. In fact, it should be more of a reason to make a visit to the dentist. Regular gum exams are very important during this time, for hormonal changes increase the risk of periodontal disease. It is important to pay close attention to any changes in the gums, whether there are signs of swelling or even bleeding.

 

The months of pregnancy can be both an exciting and stressful time, but with proper maintenance of both oral and overall systemic health, expecting mothers are then set on a path to a smoother pregnancy.  If you have any more questions, feel free to contact Drs.

Bleeding Gums: What Can This Mean?

July 23rd, 2013

When the topic of oral health is brought up, the focus is usually placed on teeth and the possibility of getting cavities. However, there is definitely more to the mouth! Gums can be a good indicator of oral health as well as one’s overall health! Individuals may find that after brushing their gums may look red and they may even start bleeding. Many tend to dismiss these signs and just attribute them to good and thorough brushing. But wait! This is not the case.

First things first, there is a misconception that to get clean teeth, brushing needs to be done vigorously to get all the grime off. While afterwards your teeth may feel clean, your gums are not too pleased.

Remember: gums are made of soft tissue and when aggravated they can become sore and red. When choosing a toothbrush, it is important to opt for soft nylon bristle with blunt ends. Stores may carry brushes with medium or hard bristles; however they may damage the enamel on teeth and can cause swollen gums. The idea of being gentle goes the same for flossing. The goal of flossing is to remove leftover food and plaque stuck between teeth; it does not mean these particles need to be forcefully taken out. It is important to refrain from forcing the floss in between teeth; instead, carefully slide the floss up and down, following the curve of each tooth.

Aside from proper brushing and flossing, bleeding gums is actually a sign of gum disease. When proper dental hygiene is not practiced, bacteria takes over and plaque starts forming. The same bacteria that jumpstarts the formation of cavities as makes gums irritated and swollen. Bleeding gums is an early sign of gum disease, also know as gingivitis, and symptoms can be reversed with good oral hygiene. But if these symptoms are ignored, gingivitis can get worse, eventually leading to tooth loss. Be on the lookout for these symptoms:

- deep pockets between teeth and gums
- changes in the way teeth come together
- gums that bleed during/after toothbrushing
- shifting teeth
- red, swollen, tender gums

If you experience these symptoms, be sure to set up an appointment with the dentist to determine the necessary steps to keep these symptoms from getting worse. Feel free to contact Drs. Ali & Ali and the caring team at Wellesley Dental Group if you have any thoughts or concerns; they will be happy to answer your questions!

Stick with Mussels: they can help strengthen and rebuild teeth!

July 19th, 2013

Good news for all you seafood lovers out there. The Journal ACS Applied Materials and Interfaces have found something very special about mussels’ adhesive nature. Not only does it let these creatures hold fast to rocks in the ocean, researchers have found that they also can be beneficial for teeth.

Quan-Li Li, Chun Hung Chu, and other researchers noted that there are three out of four people who have teeth sensitive to hot, cold, sweet or sour foods and drinks. These scientists were determined to look for ways to rebuild enamel and dentin, which are important factors that determine tooth sensitivity. They found that mussel’s natural adhesive, which allows them to attach to rocks, can be a synthetic substance used to reform the eroded enamel and dentin. They worked under the hypothesis that the sticky substance in mussels would have the ability to keep essential minerals in contact with dentin long enough for reformation to occur.

In 2011, an international team of scientists that mussel’s adhesive proved to be a successful alternative to other coatings used in teeth. While most coatings tend to make teeth weak and brittle over time, the synthetic coating created from mussel adhesive had the ability to heal itself when damaged. The researchers also found that minerals in other coatings were only able to reform enamel while the synthetic adhesive was able to reform both enamel and dentin. Phil Messersmith of Northwestern University have taken into account mussels’ incredible adhesive properties and have created a polymer used in coating that can mend tears in just a matter of minutes!

While these scientists continue to incorporate this newfound adhesive to the clinical setting, there are still ways to battle sensitive teeth. Doctors continue to recommend that individuals practice good oral hygiene (brushing twice a day and making sure to floss carefully). Those with sensitive teeth can also be extra careful when consuming acidic foods such as juices, vinegar in salad dressings and soft drinks. A good way to protect teeth is to rinse the mouth with water after consuming these foods. Teeth grinding can also leave teeth susceptible to sensitivity; ask the dentist about a mouth guard for nighttime use to prevent teeth grinding.

Safety First: Protecting Your Teeth in Sports

July 18th, 2013

When people go out for a game of basketball or soccer, many don’t usually think about teeth. Dentists recall numerous stories where patients have come in with chipped or even missing teeth due to an intense game on the court. In order children and a

dults, sports injuries tend to be common. It has been estimated that 13-39% of dental-related injuries happen when an individual is engaged in sports. About 80% of the injuries are located in the front teeth or even the tongue and cheek. The American Academy of Pediatric Dentistry (AAPD) recognizes high rate of sports-related dental injuries in today’s youth and continues to look for means for prevention. 

Even if an individual takes one to the mouth and ends up with a missing tooth, a dentist is able to save the tooth. Cracks and chips in tooth can be repaired through using tooth-colored materials that are just as strong as the original tooth. Although dentists can easily come to the rescue, these injuries can turn out to be pretty serious and procedures are not a small cost. Dentists have strongly recommended the use of mouth guards for football players. With this movement, mouth guards have been able to prevent about 200,000 injuries annually.

There are various means of protection when playing a sport. Here are two types of protection that are recommended:

Mouth guards: like it was previously mentioned, mouth guards have done a great job in protecting sports players. They can prevent injury to one’s teeth, tongue and lips. Dentists tend to recommend athletes to get a custom-fit mouth guard; however, individuals can opt for ready-made mouth guards that can be found in sporting-goods stores.

Helmets
: people usually do not think that protecting their head means protecting their teeth as well. As a matter of fact, helmets are very effective in protecting both the head and the oral cavity in high speed and impact sports. These sports usually include hockey, football, bike riding, and skating. It is important to note that there are helmets specially made for a certain sport. When purchasing a helmet, be sure to check and see if the helmet fits correctly.

Sports are definitely a healthy way to distress and have some fun. But make sure that safety is first! If you have any more questions, feel free to contact Drs.

General and Oral Health Benefits of Breastfeeding

July 16th, 2013

The American Academy of Pediatrics (AAP) issued a policy statement back in 2012 stating that breastfeeding and the use of human milk have show to reduce health risks for infants, children, and mothers, also including advantages such as developmental, nutritional, immunological, and psychological benefits. The APP exclaims that breast milk is the best nutrient source for babies. It contains immunological agents, including secretory immunoglobulin (g) A and IgG, along with anti-inflammatory properties that act as protection for the infant’s immune system.

Researchers found that compared to formula-fed children, children who were breast-fed had a lower risk of diarrhea by coating intestinal lining and killing dangerous pathogens that leave babies prone to infection. Breast milk also combats severe lower respiratory infections, including pneumonia and virus bronchiolitis; a child’s risk of developing asthma is also reduced. The immunological and anti-inflammatory properties of breast milk controls to onset of infection and illnesses, reducing sudden infant death syndrome (SIDS). Breastfed-children are also less likely to develop obesity, which is a prevalent disease that 12.5 million children and teens suffer from today. Breastfeeding helps protect against obesity by improving self-regulation of energy intake and recognizing when one is full. On top of these general health benefits, breast-fed children showed better occlusion, where their top and bottom teeth came together more favorably.

The American Academy of Pediatric Dentistry (AAPD) suggests that parents should clean infants’ gums even if they do not have teeth. Parents can use a soft washcloth to clean the gums. The AAPD also recommends that breastfeeding should be exclusive for about the first six months of life; this should continue past six months with the gradual introduction of foods fit for the baby.
