Last time I saw a dentist he told me I had about 4 cavities starting to form and that he could fix them that day. I asked how long it would be until they start hurting if I don't get them fixed now. He told me about 6 months. I said I'll wait for that. Its been 5 years and I haven't seen a dentist since. I am not going to worry about it and don't plan on seeing a dentist at all.
