The Facts on Fluoride


More often than not, when you visit your dentist for a cleaning, you’ll hear the word ‘fluoride’. But do you really know what that means? If you don’t, this blog will tell you what you need to know about fluoride.


Let's start with the big question, what is fluoride?


Fluoride helps prevent tooth decay as it makes strengthens the surface of the teeth, called enamel. It can prevent or stop tooth decay. Fluoride is a mineral that can be found in soil, various foods, and both fresh and saltwater. Fluoride is naturally found in as well as added to most public water in Canada. Another common source for fluoride is in toothpaste and rinses that have the Canadian Dental Association (CDA) Seal of Recognition on it.



CDA Seal of Approval


When purchasing oral hygiene products, look for the CDA Seal to ensure the products you are purchasing have been validated by the CDA and will provide the health benefits they claim to bring.




Types of Fluoride


During your visit, your dentist can provide you with professional products containing fluoride including varnishes, foams, and gels. Here at Stony Plain Dental Centre, we have all three forms as well as silver diamine fluoride (SDF). SDF is a type of fluoride that provides temporary solution to cavities. It turns the cavity black and halts decay, it requires a few applications after the initial treatment to ensure it is still preventing the cavity to grow. This treatment can be used on both children and adults, however, it is typically only used when a older adults or a small child that has a cavity on a primary (baby) tooth that will fall out in coming years. If you have any questions about silver diamine fluoride, call us at 780-963-4626.


Is fluoride bad for you?


There is a common misconception that fluoride is bad for you when in reality, it is very beneficial alongside proper oral care. Ingesting too much fluoride in childhood can cause dental fluorosis, however, it isn’t a hazard to your health. Children's toothpaste contains limited quantities of fluoride to avoid dental fluorosis. Dental fluorosis appears as small white specks on teeth in its most common form, in its mild form, it often goes unnoticed by children and parents. Other than dental fluorosis, there have been no known negative side effects to using fluoride.


If you are unsure if you or your child is receiving optimal amounts of fluoride, check with your dentist.


Is fluoride free?


Fluoride occurs naturally in some forms and is naturally found in most water sources. Additional fluoride is also added to most public water in Canada. Additional fluoride treatments are not free but can be purchased with fluoridated toothpaste and rinses for a low cost as mentioned earlier. When receiving fluoride treatments from your dentist, your insurance may cover part of the cost. Depending on your insurance, it typically covers one fluoride treatment a year. You can check with your insurance provider to find out your plans coverage for fluoride.


Why should I pay for fluoride treatments?


If you are at risk of tooth decay, fluoride treatments are strongly recommended. Poor oral hygiene at home and high sugar intake can increase your risk for tooth decay which can increase the number of fluoride treatments you may require. Proper oral hygiene at home, routine visits to your dentist, and multiple fluoride treatments within a year can dramatically increase your oral health. Talk to your dentist or hygienist to see how many fluoride treatments a year you require.


Should I use fluoridated toothpaste?


Along with regular care by your dentist, fluoridated toothpaste and rinses help prevent tooth decay and should be used.Using fluoridated toothpaste for children three and under is only necessary if they are at risk of developing tooth decay which can be determined by your dentist. If your child is at risk and the use of fluoridated toothpaste is recommended, a small portion, the size of a grain of rice should be used. This prevents them from using and swallowing too much toothpaste which could put them at risk of dental fluorosis. If fluoridated toothpaste isn’t recommended, their teeth should be brushed using a toothbrush and damp water. Ensure an adult brushes their teeth for them, with or without the use of fluoridated toothpaste.

Children three to six should use a small portion, the size of a pea, and should be assisted or supervised. Rinses that contain fluoride should not be used on children under six.
