How do cavities occur?

When food, acid and saliva combine with bacteria in the mouth it creates plaque, a sticky substance that covers teeth. Plaque eats at tooth enamel and causes a hole in the tooth, also known as a cavity. Once tooth decay progresses and a cavity forms, it cannot heal itself. That鈥檚 why it鈥檚 important to brush all your teeth twice a day, to keep plaque away!

鈥淧arents sometimes ask why they should worry about their child鈥檚 oral care, since baby teeth are going to be replaced. But there are many reasons to prioritize regular dental hygiene,鈥� says Dr. Fatemeh Basij, DDS, former UBC instructor and the owner of . 鈥淓stablishing healthy habits early will help your child when it鈥檚 time to care for adult teeth. Also, untreated cavities can also cause pain and infections 鈥� in addition to being uncomfortable, dental issues can lead to problems with eating, speaking and learning at school.鈥�

What increases the risk for cavities?

• Family history: Some people may be genetically predisposed to getting cavities. If other family members have had cavities, your child may be at a greater risk.
• Sugary foods: If your child consumes a lot of sugary foods and drinks, particularly between meals, they have an increased risk of developing cavities.

• Special healthcare needs: It can be even more challenging to develop good dental hygiene routines for children with special needs. People with special healthcare needs including Alzheimer鈥檚 Disease and Dementia are also at an increased risk for cavities.
• Braces and other oral appliances: If your child wears braces, orthodontics or other oral appliances, it鈥檚 easier for food to get stuck in their teeth, which increases their risk of cavities.

鈥淚f your child is at an increased risk of cavities, talk to your doctor or dentist. In addition to regular oral hygiene, there are extra steps you can take to help protect your child鈥檚 teeth,鈥� Dr. Basij says.
