We have different kinds of caps to protect your teeth. When a filling is not enough, you have to decide which of the different materials are best to use. Porcelain crowns, gold crowns and gold/porcelain crowns, are the best to choose. For your front teeth, a ceramic crown is best. For your back teeth, I recommend gold crowns. Permanent fixed bridges are good options to replace a missing tooth, preparation on the tooth in front and the tooth on back of the extracted tooth is necessary. Same materials as for the crowns are available. Two visits minimum to do it, preparation and temporaries first day, check up and cementation on the second visit.
