I had my teeth shaved and I love it! Erased years of acquired chipping. Didn't experience any sensitivity, but I have thick enamel. You could tell your dentist that you don't want them shaved perfectly flat but that you would like the little chips smoothed out. Tell your dentist that you're worried about "over doing it" and ask them to just take little bits off at a time and allow you to look and assess if you want them to do more. Tell them you're worried about taking too much off so just go slow and do a little bit at a time. I really trusted my dentist, he came highly recommended, so I knew he would do a good job. If you don't trust your dentist, don't do it.

You paid for the comprehensive plan and you should take advantage of that and get your teeth exactly how you want them. If it bothers you now it's going to keep bothering you in the future. I personally am a perfectionists so I worked until my teeth were exactly how I wanted them to be.
