I have had 8 top teeth altered via veneers and crowns. i feel like i have an overbite now. is it possible that the reconstruction caused it and can it be fixed?

It should be fixable: The veneers and crowns should not change the way your bite or look, unless that was the reason to have them done in the first place. Have your dentist check your bite and the shape of your crowns/veneers to make sure that they are satisfactory to you.

Overbite?: Can't tell without seeing the case. You don't say how long you have had this treatment, but it often takes time to get accustomed to the new restorations. If you are uncomfortable, you should discuss your concerns with your dentist. However, in most cases, once the restorations are permanently cemented or bonded, any changes can only be accomplished by re- doing the restorations.

Very possible...: ... But impossible to tell over the internet, sight unseen. The shape of the crowns and veneers and how they may have changed your bite is dependent on the position of those teeth and their relationship to the mandibular teeth. Careful planning and consideration, as well as temporaries that mimic the final result could have prevented this concern of yours. Speak to your dentist and elaborate.

Tryin evaluation?: An overbite refers to the degree that the upper front teeth overlap the lower front teeth. With new restorations, when first placed, the look and feel, even with small differences, may become magnified. Discuss your feelings with your dentist. The length of the teeth may be able to be shortened if everything else is to your satisfaction. If not, it generally requires redoing the restorations.

Thickness: Veneers have a mandatory thickness that allows them not to fracture and to mask the underlying enamel. Sometimes tooth structure must be rremoved to allow for the thickness without protruding the teeth. Discuss with your dentist and revisit your original goal.

Need to see: See a Prosthodontist for an evaluation and assessment. They are the specialists in reconstruction. Often , veneers add bulk to the teeth if underprepared, as can crowns.Perhaps this is so in your case. See the expert. You will benefit. Good Luck.
