Your dental crown should not affect your speech or chewing ability, as long as it fits properly and comfortably on your tooth. Your dentist will ensure that your crown has the right size, shape, and alignment, and that it does not interfere with your bite or your adjacent teeth. You may experience some temporary changes in your speech or chewing after getting your crown, as your mouth adjusts to the new restoration. However, these changes should subside within a few days or weeks, as you get used to your crown. If you notice any persistent or severe problems with your speech or chewing, you should contact your dentist for an adjustment.
