Tooth Decay Rate Dropping in Australia

Home/Tooth Decay Rate Dropping in Australia

According to new research by Roy Morgan, Australians are doing a better job of taking care of their teeth. The rate of cavities among adults 14+ in Australia has dropped from 19% to 14%. However, not everyone is benefiting from the decrease, and some major lifestyle factors contribute to significantly higher decay rates.

Class and Tooth Decay

One of the biggest impacts on tooth decay risk is economic class. People in wealthier income quintiles have much better access to general dentistry including preventive checkups and cleanings, resulting in lower rates of decay than those in the lower quintiles. In the top and second to the top quintiles, the rate of decay is 11% and 14%, but in the bottom two quintiles, the rate is 17% and 16%.

Lifestyle Choices Make the Difference

Cigarette smokers were 9% more likely to have tooth decay, with 23% of Australian smokers over the age of 18 having tooth decay.

Sugary and acidic, soft drinks can significantly increase the risk of cavities. Among Australians who drink at least one soft drink a week, 16% had tooth decay. This rate increased to 19% for those who consumed 8-14 soft drinks in a week, and 22% for those who consumed 15 or more soft drinks over the course of a week (more than two a day).

Fast food consumption also increased tooth decay rates. Among those eating fast food an average of five to 9 times over the course of four weeks (about 1-2 times a week), 16% had tooth decay, and those who went 10 or more times over the period had a tooth decay rate of 19%. This may be partly due to the presence of soft drinks in fast food meals.

Roy Morgan also used its personality engine to (Helix Personas) to make a couple of unusual connections. Coupon clippers, it says had as high a rate of tooth decay as smokers, 23%. Lower income and high smoking rates account for the difference, they say. On the opposite end of the spectrum is the Worldly and Wise segment, which has a decay rate of just 9%. Affluent and concerned about health, these people invest in keeping their teeth in top shape.
