What Are Dental Sealants?

April 24, 2018 | Posted Education

Dental sealants are thin plastic coatings that are applied to the chewing surface and grooves of the back teeth where decay most often occurs. Proper brushing and flossing habits help remove plaque from the smooth surfaces on teeth, but often the bristles of your toothbrush are not able to reach all the way into the deep grooves on your back teeth to clean them. Dental sealants protect these grooves by “sealing out” any food and plaque.
Sealants are quite easy for your dentist or hygienist to apply. They get painted onto your tooth enamel where it bonds with your teeth and hardens. As long as the sealant remains undamaged, it will protect your teeth from decay, which means sealants usually last for a number of years. Some sealants also contain fluoride, which can further prevent decay.
When you visit your dentist/hygienist after receiving sealants, your dentist will inspect their condition and reapply when necessary. If you are interested in having dental sealants applied to your teeth, ask your dentist during your next visit, or contact us at the Rideau Dental Centre by calling 613-230-7475 to book an appointment.

Cavities develop when the enamel that protects the outer surface of our teeth is damaged by plaque. If you have cavities it is extremely important to get them treated by your dentist as soon as possible.
If your dentist or dental hygienist finds a cavity in your mouth, your dentist can treat it by placing a filling after removing the decayed tissue. There are a number of different types of fillings including:

  • Amalgam Fillings: This is the type of filling that most people are familiar with, it has been in use for over a century. Amalgam fillings are silver in colour, which means that they aren’t as preferable for use in more visible teeth.

  • Composite Fillings:  Composite fillings are made of a tooth coloured material that is much stronger and more durable than the material used in amalgam fillings. It also takes longer to place these fillings than it does to place amalgam fillings.

  • Ceramic Fillings: These fillings are made out of porcelain, they are aesthetically pleasing and fairly durable, however, if they become rough they can wear opposing teeth.

  • Glass Ionomer Fillings: This type of filling is made of an acrylic and glass material. They release fluoride which can help prevent further tooth decay. Unfortunately, these fillings only typically last five years or less, so they are not usually prefered over other filling types.
