A dental crown and bridge is a solution for damaged teeth. When the teeth get damaged, dentists often carry out a dental filling treatment. However, if the damage is too serious (deep decay, broken, root canal, etc.) and a filling would not hold, a dental crown over the damaged teeth may be recommended to restore its original shape and make it work more effectively while chewing.
Dental crowns can be fabricated out of different materials, including all-metal dental crowns, normal metal (stainless alloys such as alloys Ni-Cr, Cr-Co, Titanium, etc.), precious metals (gold/platinum dental crowns). Especially, porcelain-fused-to-metal dental crowns (PFM) and all-porcelain dental crowns are very popular now because they look like your natural teeth.
A dental crown is a cap or total covering for a tooth which has been damaged.

DENTAL BRIDGE (Fixed Bridge)
When a tooth or multiple teeth are lost, a dental bridge might be the solution if you don’t want to wear a removable partial denture (RPD) or an implant.
To create a bridge, the dentist will first grind the natural teeth (two or more) on either side of the space where the missing tooth was. After that, depending on the amount of lost teeth, they will fill in the space with one or more false teeth. Like a dental crown, bridges are usually made of porcelain bonded to precious metal. Note that this method of making bridges is only possible if you have enough strong teeth with good bone support.
Compared with removable partial dentures (RPD), a dental bridge is more convenient because it is fixed, stable, and feels like your own teeth. However, the method might not be suitable for the elderly because of difficult hygiene requirements.
