Frequently Asked Questions

My dentist says I have a cavity and that I need a filling. But why doesn’t my tooth hurt?

Most dental problems don’t have any symptoms until they reach more advanced stages, so don’t wait for things to hurt! It is best to get a thorough dental exam, and diagnose and treat problems early. Waiting often makes problems more difficult and more expensive to fix.

Now that I'm pregnant, my gums are more sensitive and bleed more easily. Why? What happens if I have a dental problem when I am pregnant?

Changing hormone levels during pregnancy can cause normal, healthy gums to become red, irritated and swollen. This irritation, known as “Pregnancy Gingivitis” is the body’s exaggerated response to plaque and calculus.

It is very important during this time to stay current with your regular dental cleanings and exams to ensure that dental infections don’t get missed and lead to greater problems down the road. Although dentists will typically postpone major treatment until after the baby is born, emergencies do come up and need to be addressed. Because many of your baby’s organs are being formed in the first trimester, this work is ideally taken care of during the second trimester to minimize any potential risk.

My child’s baby teeth have cavities. Why should they be filled if they’re just going to fall out in a few years?

If baby teeth become diseased or decayed it can lead to pain and infection. It can also be difficult for children to eat a well-balanced meal with a mouth full of cavities. Untreated cavities also increase the amount of decay causing bacteria in the mouth. As permanent teeth erupt, they are at increased risk for developing cavities because of the higher bacteria count.

Baby teeth also hold space in the mouth for the erupting permanent teeth. If the baby teeth become decayed or are taken out too early, the permanent teeth often become crowded and will likely need braces to straighten in the future.

How much radiation do I get from a dental x-ray and how does it compare to other medical procedures?

The radiation you would receive from a traditional film dental x-ray is very low. Today, with the state-of-the-art digital x-rays available at Markham Kennedy Dental, the radiation is reduced by an additional 90%.
