Did you know there are as many types of dental fillings as there are flavors of ice cream? Okay, maybe that’s an exaggeration. Still, when you visit the dentist with a cavity, there are many filling options. Most of us just sit in the chair, open our mouths, and let the dentist work his or her magic. But have you ever stopped to consider what the dentist is filling and restoring your decayed or broken tooth with?

Five types of dental fillings

There are five basic kinds of dental filing material. The dentist decides which type to use based on the degree of the decay, the cost of the material, and the type of dental insurance you have.

1. Dental amalgam, or silver fillings, have been used to fill cavities for more than 150 years. Dental amalgam is the most common type of dental filling. It's strong, durable, and less expensive than other types.
2. Composite fillings, or white fillings, are popular because the color matches the rest of your teeth. Composite fillings are a combination of resin and plastic. They are more aesthetically pleasing than silver fillings, but are also less durable.
3. Ceramic fillings are durable and visually appealing (tooth-colored), but they are expensive. They are made of porcelain and have been shown to be resistant to staining.
4. Glass ionomers are typically used on children whose teeth are still changing. Constructed from glass and acrylic, glass ionomers are designed to last fewer than five years. The benefit of these dental fillings is that they release fluoride, which protects the changing tooth from further decay.
5. Unless you’re a rock or movie star, gold fillings aren’t common. While a gold filling is durable, non-corrosive, and can last more than 15 years, it not only takes more than one dental visit to place, but, as you can imagine, it is expensive.

We all want our best and brightest smiles, and today there are many options we can explore at home to make those beautiful smiles a reality. Whether it’s healthy habits, a healthy diet, whitening toothpaste, or do-it-yourself home products, we have golden opportunities to achieve whiter teeth.

• Healthy Habits

Proper brushing is the first step in keeping your teeth stain-free. You should devote at least two minutes twice a day to brushing, being careful to cover the areas between and at the base of teeth, where plaque you miss can form visible tartar. Ask us about the most effective brushing techniques. And please, don’t smoke. Smoking is one of the worst offenders when it comes to discoloring teeth. If you are a smoker, quitting at any point in your life will make a big difference in the whiteness of your smile—and your lasting health!

• Healthy Eating

We all know red wine, coffee, and tea cause some of our worst enamel stains. Acidic drinks such as sodas and citrus beverages can cause even more problems by eroding tooth enamel, exposing the yellowish dentin underneath. Moderation and rinsing with water can help prevent damage. But we have some dietary allies as well! Crunchy foods like apples, carrots, and celery provide a mild scrubbing effect. Dairy products such as milk, cheese, and yogurt strengthen enamel. Fruits such as strawberries and pineapples, studies suggest, contain enzymes that are natural stain removers. While no one food takes the place of brushing or cleaning, a healthy diet and a healthy body enhance any smile.

• Brushing with a Whitening Toothpaste

Toothpastes are available which can remove some surface stains, and which can keep teeth their whitest after a professional whitening. They won’t penetrate the enamel surface or change the natural color of your teeth. If these toothpastes are going to work on discolored tooth surfaces, you will usually see results within a few weeks.

• Over-the-counter (OTC) Whitening Kits

These products provide a peroxide-based gel that can be applied in a tray or with strips. If you choose a tray application, make sure trays fit properly so sensitive mouth and gum tissue is not irritated. If you decide on strips, always make sure all of the tooth surface is covered to avoid uneven whitening. These kits have more powerful whiteners than toothpastes, and so you might see better results, but tooth and gum sensitivity can be a problem.

While all these whitening methods can be helpful, there are some circumstances when a professional whitening is best. Professional gel whiteners are more powerful, and can help eliminate darker stains that OTC products can’t remove. We can make sure sensitive gum and mouth tissue is protected from bleaching agents. And, if you are on a deadline, we can provide a much faster result. Some conditions, such as deep stains caused by trauma or medication, or darker-colored caps, veneers, and crowns, require more than whitening, and we are happy to present options for those situations.

If you have any questions or concerns about whitening your teeth, please give our Nassau office a call. Whether it’s advice on how to brush or how to quit smoking, discussing the effects of foods and drinks on our teeth, suggesting OTC whitening products, or providing a professional whitening, Dr. Welmilya Francis-Davis and our team are happy to help you achieve your best and brightest smile!

YES! X-rays have been used in dentistry for a long time, and the amount of radiation has significantly decreased with advances in technology. While there is risk in every health diagnostic procedure at Comfort Smiles, the benefits must outweigh the risks. Dental X-rays do indeed fall into this category.

X-rays are exposed to a type of film to produce an image. The amount of X-rays required to produce this image differs with film speeds. Speed E or F is highly recommended, and digital X-rays require up to 50% less than speed E or F film. The digital X-ray software can adjust the exposure to produce a quality image. Digital X-rays are becoming a new standard and are most common.

Lead aprons have been used to reduce the amount of scatter radiation. All X-ray units have a cone to focus the X-ray beam so the exposure is highly localized. Lead aprons continue to be worn as a precaution for pregnant women, and a thyroid collar should also be worn. In most cases, this is sewn into the lead apron.

We get radiation exposure from environmental factors as well as healthcare diagnostic and treatment tools. To place this in perspective, in one year a person is expected to have 360mRem per year from the sun, air etc. By comparison, a single set of bitewing X-rays is 0.3mRem. Radiation can accumulate in our body over a lifetime, and additional exposure should be avoided whenever possible.

One of the most charming aspects of your baby’s beautiful smile is his brilliantly white teeth. But now that his adult teeth are coming in, the difference in color is very noticeable. Is this something to be concerned about? Happily, probably not.

Both baby teeth and adult teeth have the same basic structure. The inside of the tooth, the pulp, contains blood vessels and nerves. The pulp is covered by a layer of dentin, a hard, yellowish substance composed of living tissue that helps protect the pulp and transmits signals for pain, pressure, and temperature. Enamel is the outer protective covering of the tooth, and its natural color can vary from greyish-white to light yellow.

If primary and permanent teeth are so alike, how can they look so different? As with so many things, the difference lies in the details. In adult teeth, enamel is semi-translucent, so it will allow the color of what is beneath it to show through. And the color of the thick dentin beneath is naturally yellow. Baby teeth have a thinner layer of the yellowish dentin. And while their enamel is also thinner, the enamel in baby teeth is generally whiter and more opaque, so less of the underlying yellow from the dentin is visible.

The result of these small differences is that adult teeth are normally darker than baby teeth to begin with. And when a permanent tooth that is just a bit darker erupts next to a bright white baby tooth, it is going to look even more yellow than it actually is. Once all of the baby teeth in front have been replaced with adult teeth, you will have a much better idea of their real color without unflattering comparisons!

There are times when concerns about tooth color should be looked at by Dr. Welmilya Francis-Davis more closely.

• Unusual discoloration in teeth should be examined. Some discoloration is caused by medical conditions such as hypomineralization, some by environmental factors such as excess fluoride, some by trauma, some by medication. If you notice a discolored section of your child’s tooth, or the tooth has turned a different shade from the teeth around it, give us a call.
• Your child might have naturally whiter or yellower teeth simply as a matter of genetics. If your child is self-conscious about the color of his teeth, we can talk about whitening solutions when he is old enough to use them safely. Home whitening products should never be used on young children.

Give yourself time to adjust to your child’s new, adult smile. You will probably notice no difference at all once all of his permanent teeth come in. And keep those new teeth their brightest with consistent brushing and flossing, and regular checkups and cleanings at our Nassau office. This is the simplest prescription for a charming, white, and healthy smile at any age.
