A dental crown, otherwise known as a cap, covers an infected tooth and can vary in function, depending on the position of the tooth. Crowns cover all the visible parts of a tooth and vary in size, appearance, and functionality.

A crown can be used to protect a weak tooth from breaking, hold together an already broken or worn tooth, cover the tooth with a large filling or dental implant, hold a dental bridge in place, or support a cosmetic modification.

Several types of crowns are available, depending on the tooth to be treated. Stainless-steel crowns are used on permanent teeth, usually as temporary measures in children because they’re more cost-effective for baby teeth that naturally come out over time.

Metal crowns are another option that includes gold alloys, or base-metal alloys. Metal crowns are notable for their ability to withstand biting forces, rarely break or chip, and therefore offer the best results in terms of normal wear and tear.

Porcelain fused to metal crowns most closely resemble a normal tooth and are a good choice for front or back teeth. Other, less common types include all-resin, all-ceramic, all-porcelain, and zirconia crowns.

If you’re getting a crown, you can expect a few things during your visit with Dr. Nymberg. Crown placement usually requires two appointments. The first entails preparation to get an impression of the tooth, shape it, and place a temporary crown. The impression is sent to a lab where a technician makes the crown to be fitted.

During the second appointment, the high-quality porcelain crown is placed on the problematic tooth.  

If you notice any signs of discomfort in your mouth, always let Dr. Nymberg know by calling our Mason office. We will determine which type of crown is best for your tooth to give it the added strength it needs. Crowns can be very helpful for your oral health if you have any teeth that need extra support.

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. Nymberg 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 Mason 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!

The electronic toothbrush has undergone several technological advances since the 1960s. Everything from design and bristle motions to rotation, oscillation, and sonic vibration has led to dramatic changes in this necessary tool over time.

Rotation oscillation happens when the head of the toothbrush rotates from one direction to the other. The benefit of powered toothbrushes is that they can produce 50,000 strokes per minute, compared to 300 strokes with a manual toothbrush.

When you’re thinking about brush head size, smaller brush heads are best for hard-to-reach areas and small mouths. Brush heads should be replaced every three to six months as needed. A good way to save money is to designate a brush head for each family member which can be taken on and off a shared base motor.

Having a base motor or rechargeable toothbrush can deliver enough power on a full charge for a week of brushing, which makes it convenient for travel or when life gets busy. Some toothbrushes include audible signals that let you know when to switch the area of your mouth you’re brushing or when a full two minutes has gone by.

Do you have sensitive teeth? Studies have indicated that people tend to apply more pressure on their teeth when they use a manual toothbrush. This makes an electric toothbrush a preferable option if you’re having issues with sensitive teeth or gums.

There are even electric models with pressure sensors that will stop the brush from spinning when you press too hard against your teeth!

Everyone can benefit from having an electric toothbrush. A large handle size can be taken into consideration if a member of the household is young, or has a physical disability or arthritis. They’re even recommended for children in order to maintain good oral hygiene from a young age.

Biofilm is a term used for plaque or debris that builds up in your mouth. If not properly addressed, this can cause serious bacterial infections to your gums and teeth. If you want to remove biofilm in the most efficient way, an automatic toothbrush is the way to go.

When you're ready to make your decision, make sure to consult with Dr. Nymberg at our Mason office to decide which electric toothbrush is right for you!

Dr. Nymberg will tell you that while you are sleep, your mouth may be very active. If you find yourself waking up with headaches, facial pain, neck aches, or a sore jaw, you may have tooth grinding, a condition we also call bruxism.

We see many people who experience some extent of tooth grinding, but a very small percentage of the population actually experiences symptoms severe enough to warrant visiting a doctor. If you continually experience any of the symptoms listed above, we encourage you to give us a call at our Mason office so that we may be able to diagnose and treat the problem.

The most common treatments include:

• Reducing your stress level to help relax your jaw muscles and prevent grinding
• A custom-made night guard to cushion your teeth and protect them from damage
• Changing your eating habits. Coffee, tea, or alcohol before bed can increase your chance of nightly grinding
• If your jaw or teeth are misaligned, Dr. Nymberg may also recommend a brace to decrease grinding.

Grinding your teeth can have serious consequences that, if left untreated, can lead to tooth fractures and damage to the TMJ (temporomandibular joint).

If you think your teeth may not be getting the rest they need at night, we encourage you to give us a call and schedule an appointment with Dr. Nymberg. Call us today!
