How often you go for a dental exams depends on your oral health needs. The goal is to catch small problems early. For many people, this means a dental exam every six months. Your dentist may suggest that you visit more or less often depending on how well you care for your teeth and gums, problems you have that need to be checked or treated, how fast tartar builds up on your teeth, and so on.

Ask yourself the following questions:

• Do I floss every day?
• Do I brush twice a day with a fluoride toothpaste and follow my dentist's instructions on how to brush properly?
• Do I eat a well-balanced diet, including food from all food groups, and limit sweets and sticky foods?
• Do I smoke?
• Do I have a history of cavities or gum disease?
• Is my overall health good?

The answers to these questions are all factors that affect your oral health. They will help you and your dentist decide how often you need to visit for dental exams. It's worth noting that you should not determine your need for dental care on what your dental plan covers.

How often you need to have x-rays also depends on your oral health. A healthy adult who has not had cavities or other problems for a couple of years probably won't need x-rays at every appointment. If your dental situation is less stable and your dentist is monitoring your progress, you may require more frequent x-rays.

If you are not sure why a particular x-ray is being taken, ask your dentist. Remember that dental x-rays deliver very little radiation; they are a vital tool for your dentist to ensure that small problems don't develop into bigger ones.

• Location
• Hours of practice
• Language(s) spoken
• Generalist or specialist practice
• Ask your family and friends if they can recommend a dentist. Other members of your community, such as your doctor, may be able to offer suggestions. Some provincial dental associations have Web sites that allow you to search for a dentist in your area (see "Other Resources" below).

Once you have narrowed your list to two or three names, call the dentists to see if they are accepting new patients. This initial call may also give you some sense of the office environment, but there's nothing like the first visit to help you decide if it's a good match for you.

Original dental records belong to the dentist who provided the treatment, and not the patient, because dentists have to keep all of their records for a period of time, as set out by their provincial dental regulatory body.

Once you have selected a new dentist, you can request that a copy of your records be transferred from your former dentist. You may be required to sign a release form from your former dental office and you may also be charged an administrative fee for having your records copied and sent to another dental office. If you have questions about the records transfer process in your province, ask your dentist or contact the provincial dental regulatory body.

Your health is very important to your dentist. One of the ways that your dentist helps you stay healthy is by preventing the spread of germs. One of the best ways to do this is to use barrier protection such as gloves and masks.

Your dentist and other dental team members also wash their hands regularly. In addition, they sterilize equipment used in the dental office and clean the furniture and fixtures in the examining rooms. This system is referred to as "standard precautions." It means that every patient is treated in the same way because patients don't always know if they're sick. It's always better to be safe than sorry.

If you would like to know how this system is carried out in your dentist's office, ask to be shown how it's done. Dentists welcome the opportunity to ease their patients' concerns, rather than have them leave the office with unanswered questions. Once you see the work that goes into making the dental office a clean and safe environment, you will feel reassured.

It is worth noting that even though standard precautions are used, it is still important to tell your dentist of changes in your health. This will help your dentist suggest the right choices of treatment for you.

It's important to get an early start on dental care, so that your child will learn that visiting the dentist is a regular part of health care. The first step is to choose a dentist for your child.

It may be your own dentist or one who specializes in treating children (called a pediatric dentist). Once you have selected a dentist, call the office to find out at what age he or she prefers to see child patients for the first time. CDA encourages the assessment of infants, by a dentist, within 6 months of the eruption of the first tooth or by one year of age.

It's important to make the first visit a positive experience for your child - one reason why it's best to visit before a problem develops. If you think there is a problem, however, take your child to the dentist right away, no matter what age.

If you are a nervous dental patient, ask your spouse or another family member to take the child for the appointment. If your child senses that you are nervous, he or she may feel nervous too. When you talk to your child about going to the dentist, explain what will happen without adding things like "it won't hurt" or "don't be scared."

Be sure to get an early start on regular dental care at home. Start cleaning your child's mouth with a soft damp cloth before teeth come in and continue with a soft toothbrush once he or she has a first tooth. Limit the number of sugary treats you give your child, and focus on healthy food choices from the very beginning.
