Going to the dentist is something a lot of people are inclined to put off. Ironically, this raises costs in the long term. Unattended, a tooth which has a cavity decays further, requiring a root canal eventually. Filing a cavity costs around $150-$300 while a root canal costs more, as much as a $1000 or more if you do not have dental insurance. A lot of people do not have dental insurance in the United States. Unsurprisingly, the percentage of people who need dental care but have not opted for it has risen from 29.5% to 31.6% from 1988-1994 to 2011-20141.
