Replacing lost teeth has important benefits for your appearance and health. Dentures also known as false teeth are designed to replace missing teeth. Dentures can be partial or complete. Partials replace one or a few teeth while complete dentures cover an entire jaw. Latest advances in dentistry have made dentures become more comfortable and natural looking. Patients considering dentures must know that a new denture will not last them forever. Also, dentures may feel uncomfortable for the first few weeks and some people may get unhappy while wearing it. Lower dentures may never feel like natural teeth and may also restrict your ability to speak or eat. Upper dentures are however easier to wear. Be sure to consult your dentist whether new sets need to be made.
