hi scary,
i went to the dentist for the first time last december (at age 39), so you can imagine the things wrong with my teeth: decay, abscesses, bone loss and loose teeth, overcrowding, etc etc. one of my bottom front teeth fell out and that was what finally got me to the dentist. since then i've had a deep cleaning, 15 extractions (with abscesses cleaned out and sockets bone grafted at the same time), upper and lower immediate partial dentures and 2 cavities filled, and i'm headed for implants as soon as my grafts heal.
honestly, the worst part of ALL of this was...making that first phone call to make an appointment. i knew this wouldn't be easy but i felt SO relieved that i'd at least got the ball rolling, and i found an amazing periodontist and a talented prosthodontist. i had all 15 extractions done at once and did not have pain during or even after; i had no problems speaking with the partials and adjusted fairly quickly to eating with them. i was of course terrified before my extractions and i'm still pretty scared before any appointment, but my imagination is way worse than anything that actually happens.
i hope this also gives you some encouragement. i knew that if i did nothing that things would only get worse, and i can't describe how relieved i am and how worth it it all is, even with all the fear and not-fun dental visits.
