Congratulations on your new smile! I would recommend asking your dentist why the refinements are needed. If the refinement is for aesthetic reasons you can take a pass. If it is needed to make a correction in your bite it is in your best interest to complete the treatment. Good Luck
Dental infections during pregnancy should be treated right away. The good news is that the third trimester is the safest time to have dental work. It is always a good idea to check in with your OB/Midwife before your dental visit.
Have you considered Invisalign to straighten the teeth before bonding or veneers? Correcting the position of the teeth before Veneers or bonding will keep the required tooth preparation / reduction to a minimum. An added benefit is that eliminating the crowding will help keep your gums helathy. Good Luck!
The good news is that the composite that bonds the invisalign attachments to your teeth can be easily polished and adjusted so that you are comfortable. In the meantime, dental wax is readily available at most drug stores and should help until you get back to the dental office. Good Luck!
The procedure your dentist is describing often works but is unpredictable. It is certainly the most cost effective way to treat the problem but may need to be repeated in the future. Good Luck!
