We’re all friends here, so if you sometimes feel a bit nervous before your dental appointment, no judging! Ask us about any worries you might have. We are happy to explain procedures, equipment, and sedation options so you know just how safe and comfortable your experience can be. And if X-rays are a concern, we can put your mind at ease here as well.

What Exactly Are X-rays?

Sometimes patients feel reluctant about the process of imaging because X-rays are a kind of radiation. But the fact is, radiation is all around us. We are exposed to radiation naturally from our soil and water, sun and air, as well as from modern inventions such as cell phones, Wi-Fi, and air travel.

Why is radiation so common? Because matter throughout the universe constantly gives off energy, and the energy that is emitted is termed radiation. This radiation takes two forms—as particles (which we don’t need to consider!) and as traveling rays. This second type is known as electromagnetic radiation, created by photons traveling in regular waves at the speed of light.

We are exposed to electromagnetic radiation every day, because, whether we can see them or not, these different wavelengths and frequencies create various forms of light. Radio waves, microwaves, infrared, visible, and ultraviolet light, X-rays, and gamma rays are all part of the electromagnetic light spectrum.

Different types of radiation on this spectrum have different wavelengths and different frequencies, and produce different amounts of energy. Longer wavelengths mean lower frequencies and less energy. Because X-rays have shorter wavelengths and higher frequencies than, for example, radio waves and visible light, they have more energy.

How Do Dental X-rays Work?

An X-ray machine produces a very narrow beam of X-ray photons. This beam passes through the body and captures images of our teeth and jaws on special film or digital sensors inside the mouth (intraoral X-rays), or on film or sensors located outside the mouth (extraoral X-rays). These X-ray images are also known as radiographs.

Why are X-rays able to take pictures inside our bodies? Remember that higher energy we talked about earlier? This energy enables X-rays to pass through the softer, less dense parts of our bodies, which are seen as gray background in a radiograph. But some substances in our bodies absorb X-rays, such as the calcium found in our bones and teeth. This is why they show up as sharp white images in radiographs.  

There are different types of common dental X-rays which are used for a number of reasons:

• Bitewing X-rays, which are used to check on the health of the back teeth.
• Periapical X-rays, which allow us to look at one or two specific teeth from crown to root.
• Occlusal X-rays, which show the entire arch of teeth in the upper or lower jaw.
• Panoramic X-rays, which use a special machine to rotate around the head to create a complete two-dimensional picture of teeth and jaws.
• Cone Beam Computed Tomography, an external device which uses digital images to create a three-dimensional picture of the teeth and jaws.

Why Do We Need X-rays?

If all of our dental conditions were visible on the surface, there would be no need for X-rays. But there are many conditions that can only be discovered with the use of imaging—infection, decay, a decrease in bone density, or injuries, for example, can show up as darker areas in the teeth or jaws. Among their many diagnostic uses, X-rays can help us find:

• Cavities between teeth or under old fillings
• Damage to the tooth’s pulp which might require root canal treatment
• Injuries to teeth or roots after trauma
• Abscesses, tumors, or other conditions that might be causing swelling or pain
• Position and development of wisdom teeth
• Ideal placement for implants
• Health and density of the jaw and alveolar bone

X-rays can also serve an important preventative role, by discovering small problems before they become major ones.

How Do Dentists Make Sure Your X-rays Are As Safe As They Can Be?

First of all, the amount of radiation you are exposed to with a dental X-ray is very small. In fact, a set of bitewing X-rays exposes us to slightly less than the amount of radiation we are exposed to through our natural surroundings in just one day. Even so, Dr. Welmilya Francis-Davis and our team are committed to making sure patients are exposed to as little radiation as possible.

Radiologists, the physicians who specialize in imaging procedures and diagnoses, recommend that all dentists and doctors follow the safety principal known as ALARA: “As Low As Reasonably Achievable.” This means using the lowest X-ray exposure necessary to achieve precise diagnostic results for all dental and medical patients.

The guidelines recommended for X-rays and other imaging have been designed to make sure all patients have the safest experience possible whenever they visit the dentist or the doctor. We ensure that imaging is safe and effective in a number of ways:

• We take X-rays only when they are necessary.
• We provide protective gear, such as apron shields and thyroid collars, whenever needed.
• We make use of modern X-ray equipment, for both traditional X-rays and digital X-rays, which exposes patients to a lower amount of radiation than ever before.
• When treating children, we set exposure times based on each child’s size and age.

And now that we’ve talked about some things you might like to know,

Please Let Us Know If . . .

• You’re a new patient, with previous X-rays taken during regular exams or for specific procedures. Ask to have your older X-rays sent to our office. With digital X-ray technology, this transfer can be accomplished with e-mail! Having your dental history available lets us notice any changes that have taken place.
• You’re pregnant, or think you might be pregnant. Even though radiation exposure is very low with dental radiographs, unless there is a dental emergency, dentists and doctors recommend against X-rays for pregnant patients.

X-rays play an important part in helping us make sure your teeth stay their healthiest. If you have any concerns, contact our Nassau office. When it comes to making sure you’re comfortable with all of our procedures, including any X-rays that might be necessary, we’re happy to give you all the inside information!

From a student handing out sweets for her classmates to an older married couple exchanging boxes of candy, Valentine’s Day is the time of year when people like to show affection by gifting sugary treats to their loved ones. Whether you’re on the giving or receiving end of Valentine’s Day candy, you can celebrate the holiday in a healthier way by making dark chocolate your confection of choice.

Contribute to Your Health

According to the Cleveland Clinic, studies have shown that the cocoa beans used to make chocolate contain flavonoids, which can help protect the body against damage from various toxins. Flavonoids may also help lower blood pressure and improve blood flow to the heart and the brain. Dark chocolates typically contain a higher amount of flavonoids than other types, making them a great choice for chocolate lovers. However, you should keep in mind that many companies produce chocolate that is so heavily processed that the flavonoids are largely eliminated. Your best bet is to look for high-quality dark chocolates and cocoa powders that have undergone minimal processing.

Protect Against Cavities

If you think there’s no way candy could ever be beneficial for your teeth, think again. The Texas A&M Health Science Center has reported that the tannins present in cocoa beans may actually help prevent cavities by interfering with bacteria’s harmful interaction with teeth. Just like with flavonoids, tannins have been found to be present more often in dark chocolates, rather than milk chocolates, giving you another great reason to choose the richer, sweet varieties.

Avoid a Sticky Situation

One more benefit of choosing chocolate over other candies is that it is less likely to get stuck in the crevices and spaces between teeth. Gooey sweets like taffy can stay lodged in the mouth for longer periods of time, putting you at a greater risk for developing cavities. When you choose your chocolate, be sure to avoid types that also contain sticky ingredients like caramel or marshmallow, and instead opt for the plain varieties.

Remember that the health benefits you can receive from dark chocolate are largely based on eating the candy in moderation. With that being said, it’s easy to make this delicious and health conscious switch when you’re out shopping for your sweetheart, friends, loved ones, and yourself. Have fun satisfying your sweet tooth this year and Happy Valentine’s Day from all of us at Comfort Smiles!

Now that you’re having your wisdom teeth removed at our Nassau office, you’re probably looking forward to spending a few days on the couch with a cool dish of ice cream in hand. Good! Give yourself time to heal, and choose foods that will be soothing and safe for your mouth as you recover. We’ll provide you with detailed instructions on how to take care of yourself immediately after your surgery, and that includes suggesting the best menu options.

But while you’re making your post-wisdom teeth shopping list, there are several kinds of foods and beverages that should be crossed right off. If it’s small, spicy, sticky, or steamy, put it back on the shelf. Spirits? Not this round. Drinks with straws? Absolutely not. Items like these can undermine your healing and recovery.

• Small and Crunchy

Any small particles, such as seeds or grains, or items like cookies, crackers, nuts, and popcorn which turn into small particles, can wind up lodged in the surgical site where your tooth was removed. These particles can also interfere with the blood clot that forms to protect the socket as it heals. If the clot is dislodged, there is a chance that a painful condition called “dry socket” can develop.

• Spicy

Spicy and acidic foods can irritate delicate gum tissue. It’s best to wait until your gums are back to normal before uncapping the hot sauce.

• Sticky

Sticky, crunchy, and chewy foods can be hard on the extraction site, so stick to a soft diet until you have healed. Now is the time to try all the pudding flavors!

• Steamy

Piping hot foods and drinks can interfere with the protective clot—ask us about the best time to resume your morning coffee.

• Spirits

Mixing pain medication and alcohol can be dangerous. Talk to Dr. Welmilya Francis-Davis about possible interactions. And some studies have suggested that alcohol use slows healing, so even without pain medication, it could be a good idea to wait until you are healed to toast your beautiful smile.

• Straws

And last, but by no means least, leave the straws in their little paper wrappers! Any kind of suction brings a real risk of dislodging the protective blood clot that has formed at the surgical site. Milkshakes are delicious, but eat them with a spoon. (And please, no cigarettes!)

Follow our suggestions for a soothing, safe diet, and you will be enjoying your regular menu favorites in no time. So rest, relax, eat sensibly, and enjoy that second bowl of ice cream. Doctor’s orders!

Many parents worry that their children’s teeth are not falling out on time. A lot of concerned parents want to know: When will my child lose his or her first baby tooth? At what age should the last tooth fall out? Is there a specific order in which the teeth are lost?

Dr. Welmilya Francis-Davis and our team explain that a child's 20 baby teeth (primary teeth) typically come in by age three and begin to loosen and fall out on their own to make room for permanent teeth, which usually appear by the time your child is six. It is important to know that timing may vary, and girls typically lose their baby teeth earlier than boys. The last baby teeth will likely fall out by the time your child is 13.

So, which teeth do children lose first? Baby teeth tend to fall out in the order in which they came, which means the lower center incisors are usually the first to go when your child is between six and seven years old. The next teeth your child will lose are his or her top center pair, also called the upper central incisors.

It’s important to note that if a child loses a baby tooth early as a result of decay or an unforeseen accident, his or her permanent tooth may erupt early and potentially come in crooked due to limited space. If your child suffers an injury or has tooth decay, we encourage you to give us a call to set up an appointment with Dr. Welmilya Francis-Davis.

While we know some children couldn’t be more excited to lose their baby teeth, we know others are anxious about this childhood milestone. When your child starts to lose teeth, our team at Comfort Smiles encourages you to stress the importance of proper dental care on a daily basis.

Remember to:

• Remind your child to brush his or her teeth at least twice a day. Supervise and offer assistance as needed.
• Help your child floss his or her teeth at bedtime.
• Limit eating and drinking between meals and at bedtime, especially sugary treats and drinks, such as candy and soda.
• Schedule regular dental visits for your child every six months.
• Ask about the use of fluoride treatments and dental sealants to help prevent tooth decay.
