Recommendations for a dentist/orthodontist to re-attach retainer attachments?

Hi! I am new to Houston and looking for some help. I got my retainers (and attachments) from a dentist out of town, so I can't easily go back to them. Unfortunately, two of the small attachments on my teeth (the composite 'bumps' that help the retainer grip) have fallen off.

I am looking for a reliabel dentist or orthodontist here who would be willing to simply re-attach these two attachments for me. I am a little worried that some offices might refuse such a small job and try to sell me a completely new treatment plan, which I don't need.

Does anyone have suggestions for an honest denist or ortho office that would likelu help with this?

Thanks in advance!
