Is it possible to fix my bite after the porcelain bridge is put in? It feels funny to eat.

When you get a large bridge placed, it's not uncommon to need adjustments after the adjustment and cementation in the office. You may bite differently at home or just notice high points in your daily life that you didn't notice while in the dentist's office. A follow up appointment for adjustment will help you check your bridge and bite. Further adjustment may be in order. Make notes of where you feel your bite isn't right and how you're holding your mouth to replicate it for your dentist.

Hi, thanks for sending your question. Often times when new restorations are placed in they need minor adjustments to makes sure that proper contact are in place and chewing is comfortable. This can easily be performed by your dentist in the office by first checking the contact and then adjusting as necessary. All the best
