Insurance		“My dental insurance deductible was so high, I couldn't have dental work done last year. And my knee surgery got cancelled as a result. Damn shame. Still can't afford it. [URL]” “And... 19's root canal and crown cost more than the annual dental insurance max. There go $837 of tuition money. I'm really just over this whole century.” “According to most health insurance companies teeth and eyes are luxury items that I must pay more to continue enjoying because they’re a cosmetic privilege.”
Payment strategies		“@username @username hey. I know it’s a long shot but I just had to use my rent money to have a very badly infected tooth removed and now I don’t know how I’m doing to pay rent. PLEASE help if you can God bless ya’ll doing God’s work”a “Nervous to get my tooth pulled tomorrow but mainly because I’m afraid it’s gonna cost more than what I have left on the credit card I’m using to pay for it….”
Delaying or foregoing care		“I canceled my root canal that was supposed to be Monday because my tooth quit hurting but here we are in ridiculous pain again and my husband has no job so no money to spend on it right now ” “@username Yes it is I have several teeth I need to get pulled/ worked on but can't afford it..and also take pain meds that don't seem to help much of anything...”a “@username Do you live near a dental school? When I didn’t have dental insurance, I did an expensive project at a dental school for about 1/5 the cost. It took more time, but it was worth paying less.”a
General sentiments
	Dentist mistrust	“I’m positive the dentist doesn’t really find cavities in my teeth they just want to get my money and torture me. How do I brush every day and floss and still get cavities every time”
	Dentistry is expensive	“@username Dental work is horribly expensive. I have had my very last $1700 root canal.”a
	General statements	“@username @username This is why I never want to hear another American make fun of British teeth again. People in this country cannot afford the astronomical prices charged by dentists for dental care. So they just go without dental care at all.”a
	Positive sentiments	“i spent a lotta money on my teeth and it was worth it ”
Policy statements		“@DeptVetAffairs @SenateGOP @HouseGOP I cannot afford regular dental coverage as a disabled veteran with a $200 a month income.” “My mom doesn’t have insurance for dental care...now, she has an infection in her tooth... now she needs to pay $1504 before seeing the specialist... we don’t have $1504 in the bank... This is why we need Medicare For All!!! I’m angry because of this greedy corruption #Bernie2020” “@username @username When someone has a dental problem serious enough for a root canal, they are in pain and it will be an emergency treatment. But only people with money or dental insurance can get one. Most states’ Medicaid doesn’t cover adult dental care, and if it does, they pull the tooth.”a
