Oral health

Good oral health means being free from diseases and disorders that affect our teeth, gums, and mouths. Having good oral health enables us to carry out daily tasks with ease and comfort—like talking, eating, and connecting with others.

Oral health behaviours

Practicing good oral hygiene is essential to keep gums and teeth healthy. This includes brushing our teeth twice a day (with a fluoride toothpaste) and flossing at least once a day. [1]

1 in 4 people in our community do not brush their teeth at least twice a day

Practicing good oral hygiene helps prevent tooth decay and gum disease, which can become serious if left untreated. [1] 

An icon array shows the percentage of people age 12 years and older in Guelph, Wellington County, and Dufferin County who brushed their teeth less than twice a day in 2017 and 2018. For a full description of the graph, refer to the “Read graph as text” section.

Tooth decay

Tooth decay is damage to the tooth’s surface. It is caused by bacteria that produce acids which break down the tooth’s enamel. Tooth decay can lead to cavities which can cause pain, infection, and tooth loss if left untreated. [1] 

Wellington-Dufferin-Guelph Public Health provides oral screening for children in junior kindergarten to identify oral health needs, including tooth decay.

Nearly 1 in 5 junior kindergarten students in our community have decayed, extracted, or filled teeth

Good oral hygiene habits to prevent tooth decay should start before children even get their first tooth. [2] Even though baby teeth are eventually replaced by adult teeth, habits established in childhood tend to carry over into adulthood. [3] 

A line graph shows the percentage of junior kindergarten students in Guelph and Wellington County that had decayed, extracted, or filled teeth from the 2015/16 to 2018/19 school year. For a full description of the graph, refer to the “Read graph as text” section.

Separate lines are shown for Guelph and Wellington County. The x-axis shows the school year, and the y-axis shows the percentage of students.
