I think my gums have started receding because I've started using clear aligners. I'm very early into using them but I've noticed my gums changing more than my teeth. I think more of the teeth are clearly exposed, especially my front bottom teeth. I asked my dentist about it, and he says they look good. I'm not sure if I'm being paranoid or if I should get a second opinion or seek alternative care.

I’ve been noticing my gums receding a bit. I asked my dentist about it at my last cleaning and he said they were fine. I find that hard to believe, especially the front bottom teeth. Should I get a second opinion?

I've been using aligners on my teeth and I'm already noticing gum recession. I asked about it in my last appointment and my provider said my gums look fine. This simply can't be true. My gum line looks so much lower with more of the teeth exposed. How bad is it?

I’m 39 and I don’t take any medication besides BC.

A month ago, I developed intermittent throbbing in my central incisor. I went into my provider and he assessed that the throbbing was a result of the tooth being stubborn and resisting the movement. My x-ray was completely fine. I got a second opinion and they assessed the same. My dentist then rescanned me to adjust my plan for slower movement. He then put me in a passive retainer to stabilize my tooth while we await new trays. For a few days the throbbing subsided. However, it soon returned. I got another scan and things still looked fine. Roots looked good.

My dentist then said that it’s possible that the infection is too early to show up on imaging. He wants me to start antibiotics. His assessment is that if my tooth feels better on antibiotics, then there is an early infection and we should proceed to a root canal. I got a second opinion from an endontist and she advised against a root canal and assessed that tooth is aggravated from movement. She gave me a CBCT scan, radiographs, and pulp vitality test

Has anyone ever encountered this approach? I’m hesitant to agree to a root canal without imaging proof of an infection.
