<human>: Can you condense the text into three sentences or less?

My girlfriend [24f] and I [23m] have been together for about a year now, and before I met her she chipped one of her teeth fairly substantially. She did not have dental insurance at the time, and still doesn't, so it has not been fixed or looked at at all. This would not bother me in the slightest if it weren't for the fact that her tooth is basically rotting. I love her smile and I don't want to stop seeing it because I made her feel self-conscious about it, especially since she's told me that her smile is the thing she'd most like to change about herself. 

If it were something she couldn't do anything about I wouldn't even say anything because it genuinely doesn't bother me, but I'm really worried about her dental health now and in the future. I want her to be healthy and take care of herself (and she does in all other respects, just not with this). 

I get the feeling that because she's really embarrassed about it because it is fairly noticeable, coupled with the fact that she's had issues with anxiety in the past, she is reticent to pursue any kind of treatment for it. That, and the cost of dental insurance (we're both young and, while financially stable, don't have a lot to spare).

Basically, she just really needs to go to the dentist and get her teeth looked at before it's too late. I don't want her to have to go through the process of losing any of her teeth if it can be helped. I just don't know how to approach her about it without causing her to feel self-conscious, stop smiling around me, or anything else like that. 

It's a really delicate situation and I don't want to mess this up, but I feel that I really need to say something. Any advice for how I can approach the situation so she knows I'm coming from a place of support and without judgment at all would be very much appreciated. Her smile is the most beautiful thing in the world to me and I want her to feel good about it.
<bot>: my girlfriend has a rotting tooth and I'm not sure how to help her feel comfortable getting it checked out without hurting her feelings
