Xrays...why we take them and how they are used.

Xrays...a frequent cause of confusion for patients. Often, we hear from patients that they beleive xrays are unnecessary, expensive, and unwanted. We are writing this blog to help patients to understand why xrays are so important in the diagnostic process.

There are a variety of xrays that are used in dentistry. The most common films that we use are cavity detecting or 'bitewing' xrays. Doctors use these to diagnose decay, see the margins of restorations, view bone levels and more. We normally take these films once a year. In some cases, doctors request them more often. If a patient has a high rate of decay, progressive periodontal disease, multiple restorations, and even a major change in health can dictate the need for taking these xrays.

Panorex films are a single film and show the upper and lower teeth including sinuses, the upper and lower jaw, nerve canals and more. This film will show abnormalities that doctors cannot see with other types of films. Panorex films are often used in orthodontics and oral surgery.

Full Mouth Xrays This is a series of 18 films that normally taken every 3-5 years. This set of xrays shows the roots of teeth, in between teeth, the margins of restorations, bone levels and more. These xrays are an excellent diagnostic tool and they provide the doctor with a complete view of the teeth.

Xrays are a vital part of the diagnostic process. They provide information that a visual exam cannot. Our doctors will utilize xrays when needed. The digital xray technology that we use provides safety for patients and staff.

What Can I Do To Keep My Mouth Healthy?

You can do a lot to keep your mouth healthy during chemotherapy. The first step is to see a dentist before you start cancer treatment. Once your treatment starts, it’s important to look in your mouth every day for sores or other changes. These tips can help prevent and treat a sore mouth:

Keep your mouth moist.

• Drink of lot of water. 


• Suck ice chips.


• Use sugarless gum or sugar-free hard candy.


• Use a saliva substitute to help moisten your mouth.

Clean your mouth, tongue, and gums.

• Brush your teeth, gums, and tongue with an extra-soft  toothbrush after every meal and at bedtime. If brushing hurts, soften the bristles in warm water.


• Use a fluoride toothpaste. Talk to your dentist about using a prescription fluoride toothpaste or having custom trays made for home fluoride treatments.


• Don't use mouthwashes with alcohol in them.


• Floss your teeth gently every day. If your gums bleed and hurt, avoid the areas that are bleeding or sore, but keep flossing your other teeth.


• Rinse your mouth several times a day with a solution of 1/4 teaspoon of salt or 1 teaspoon of baking soda in 1 cup (8 ounces) of warm water. Follow with a plain water rinse.


• Dentures that don't fit well can cause problems. Talk to your cancer doctor or dentist about your dentures. 

How Does Chemotherapy Affect the Mouth?

Chemotherapy is the use of drugs to treat cancer. These drugs kill cancer cells, but they may also harm normal cells, including cells in the mouth. Side effects include problems with your teeth and gums; the soft, moist lining of your mouth; and the glands that make saliva (spit).

It’s important to know that side effects in the mouth can be serious.

• The side effects can hurt and make it hard to eat, talk, and swallow.


• You are more likely to get an infection, which can be dangerous when you are receiving cancer treatment.


• If the side effects are bad, you may not be able to keep up with your cancer treatment. Your doctor may need to cut back on your cancer treatment or even stop it.

What Mouth Problems Can Chemotherapy Cause?

You may have certain side effects in your mouth from chemotherapy. Another person may have different problems. The problems depend on the chemotherapy drugs and how your body reacts to them. You may have these problems only during treatment or for a short time after treatment ends.

• Painful mouth and gums.


• Dry mouth.


• Burning, peeling, or swelling tongue.


• Infection.


• Change in taste.

If your mouth is sore, watch what you eat and drink.

• Choose foods that are good for you and easy to chew and swallow.


• Take small bites of food, chew slowly, and sip liquids with your meals.


• Eat soft, moist foods such as cooked cereals, mashed potatoes, and scrambled eggs.


• If you have trouble swallowing, soften your food with gravy, sauces, broth, yogurt, or other liquids.

Call your doctor or nurse when your mouth hurts.

• Work with them to find medicines to help control the pain


• If the pain continues, talk to your cancer doctor about stronger medicines.

Remember to stay away from

• Sharp, crunchy foods like taco chips, that could scrape or cut your mouth.


• Foods that are hot, spicy, or high in acid, like citrus fruits and juices, which can irritate your mouth.


• Sugary foods, like candy or soda that could cause cavities.


• Toothpicks, because they can cut your mouth.


• All tobacco products.


• Alcoholic drinks.

Do Children Get Mouth Problems Too?

Chemotherapy causes other side effects in children, depending on the child’s age.

Problems with teeth are the most common. Permanent teeth may be slow to come in and may look different from normal teeth. Teeth may fall out. The dentist will check your child’s jaws for any growth problems. Before chemotherapy begins, take your child to a dentist. The dentist will check your child’s mouth carefully and pull loose teeth or those that may become loose during treatment. Ask the dentist or hygienist what you can do to help your child with mouth care.
