Dental X-rays: The Inside Story

March 19th, 2025

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, Drs. Arti and Ashi 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 Issaquah 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!

Xerostomia: Big Word, Common Problem

March 12th, 2025

Xerostomia might sound like a serious and rare condition, but it’s more common than you think. If you’ve been feeling like your mouth is constantly dry, you may already be having your first encounter with it.

Xerostomia refers to when you have a dry mouth due to absent or reduced saliva flow. Now you might assume this is not a big deal, but a lack of saliva can threaten your dental health or worse, because it can be a sign of a bigger overall problem.

Some of the more common symptoms to watch for are a sore throat, difficulty swallowing, a burning sensation on the tongue, and of course, a significant lack of saliva. Because xerostomia entails a reduction in saliva, you have less of a buffer between your teeth and the food you eat, which makes you more vulnerable to cavities and tooth decay. It also means that food is more likely to get stuck in your mouth.

So what causes xerostomia? There can be many different culprits. One of the most common causes involves medication. If you’re taking antidepressants, muscle relaxers, anti-diarrhea medicine, anti-anxiety medicine, or antihistamines, this could be the reason for your xerostomia.

Dry mouth may also be a warning sign for other health issues. These can include lupus, diabetes, thyroid disease, arthritis, or hypertension. Patients that receive any kind of chemotherapy might also experience xerostomia as a side effect of their treatment.

If you’re experiencing symptoms of dry mouth, there are several things you can do:

  • This may seem obvious, but you should drink generous amounts of water. If you’re taking any of the medications known to cause xerostomia, a glass of water before and after administering the medication could be helpful.
  • Avoid heavily caffeinated drinks, since they will dehydrate you further.
  • Opt for a mouthwash that contains little to no alcohol.
  • Consume excessively sugary or acidic foods in moderation, if at all.
  • Try adding a humidifier to your room while you sleep, to add moisture to the air you’ll be breathing.

As always, stay on top of your brushing and flossing routines, and if you feel you might be suffering from xerostomia, please let Drs. Arti and Ashi know during your next visit to our Issaquah office. We’re happy to recommend products we’ve found to be successful in treating xerostomia.

The Perks of Dairy

March 5th, 2025

We all remember hearing this: “Finish your milk, it’s good for your bones!” If you have kids of your own now, you may catch yourself repeating many of the things you were told growing up.

Though parents occasionally exaggerate to get their kids to do certain things (such as eat veggies or behave), they’re spot-on about milk. Consuming enough dairy every day is crucial for growing children, because this can set them up to have strong and healthy teeth for the rest of their lives.

To understand the effects of dairy on your child’s teeth, take a look at tooth structure. Think of it in terms of layers: the innermost layer is the living tissue, the second layer is dentine (a calcified tissue), and the final one is the enamel, aka the white part of the tooth. Keep in mind that 96 percent of your enamel is made up of minerals like calcium.

Now, milk and other dairy products are excellent sources of calcium, so when you consider the need to build strong enamel for the first line of defense, it’s easy to see the connection between dairy and good dental health. When your son or daughter consumes dairy products, the body sends the incoming calcium to growing bones, which includes teeth.

This makes children’s teeth and bones stronger all around. Growing youngsters who do not get enough dairy in their diet are at risk for improper tooth development, as well as other dental problems.

According to the U.S. Department of Agriculture, children under the age of eight should be receiving at least two and a half cups of dairy per day. Children older than eight require three full cups, which is the same amount recommended for male and female adults.

If you’re looking for easy ways to incorporate dairy into your children’s diet, try snacks like cottage cheese, a milk-based smoothie, yogurt, cheese sticks, non-fat milk, and fruit parfaits, to name a few. Once you get a feel for what they like most, furnishing the ideal amount of dairy to their diet should be no problem!

If you’re concerned about your child’s teeth or have questions about a healthy diet, don’t hesitate to contact our Issaquah office and ask a member of our team.

Dental Insurance Benefits

February 26th, 2025

Dental insurance can be a great addition to your health care plan, but the way benefits are calculated can also make it a confusing one. If you have dental insurance, you might be wondering how you can make the most of your benefits. Let’s look at some of the important things to remember about taking advantage of your dental insurance.

  • Know Your Benefits

Figuring out what insurance will and won’t pay for, what percentage of a procedure is covered, what the insurance company considers an allowable fee, when you have covered your deductible for the year—these calculations are often bewildering. It’s helpful to call our office and check with your insurance provider to learn the final cost of any treatment, and how much, if any, will be covered by your insurance.

  • Use Your Benefits

Don’t lose benefits you have paid for! If you have not used your benefits, the time to do so is before the end of the insurance period (which may or may not be the end of the calendar year). When your dental plan re-starts, you will be paying for these unused benefits all over again. Similarly, if you have used your insurance and covered your deductible for the year, it makes sense to schedule your appointments before a new year brings a new deductible amount you will have to meet.

If you qualify for a certain number of preventive services such as check-ups and cleanings, you should always take advantage of this benefit—not only to find possible dental problems, but to prevent them.

And, if you have set up a Flexible Spending Account (FSA) to cover medical and dental expenses for the year, be sure to use the money in the account or you might lose it at the end of your year’s coverage. Many dental procedures are covered by an FSA—talk to our Issaquah team and your provider for details.

  • Possible Tax Deductions

If you are paying for your own dental insurance, you might be able to take advantage of the deduction for medical and dental premiums and expenses on your taxes. If your employer pays for your insurance, if you take the standard deduction, or if you spend less than a certain proportion of your income on health costs, these expenses are most likely not deductible. Be sure to check with your tax preparer or with the IRS for latest information on dental and medical deductions.

Finally, you should never put off urgent dental work because of insurance considerations. At the same time, you should be able to take full advantage of any dental insurance plan you have purchased, because you deserve to get every benefit you have paid for. Drs. Arti and Ashi and our team are here to help you work with your insurance company in any way we can. Our goal is the same as yours—insuring dental health for you and your family!
