Dental bonding, also called as composite or tooth bonding, is an excellent procedure to correct crooked teeth, chipped teeth, cracked teeth or even overlapping teeth, providing a straighter, more uniform smile in just one session.
White fillings are also called composite fillings. By composition, they are a mixture of glass or quartz filler placed in a resin medium. Dentists for restorative work especially for front teeth prefer white fillings. Some of the advantages of white filings are:
- They are durable and resistant to fractures.
- Less tooth structure needs to removal when restoring with white fillings.
- They can be bonded adhesively in a cavity, allowing a more conservative tooth repair.
- They replace the metal alloy fillings, which may evoke allergies in some people.
- They are moderate in cost.
Two points go against white fillings:
- Their placement requires longer than amalgam fillings.
- They suffer stain and discoloration over time.
White Fillings for Back Teeth
White fillings are generally considered as not appropriate restorative for back teeth. Following are the main reasons underlying this preference.
- They are not strong enough to bear the chewing force exerted by back teeth.
- They wear rather easily when placed in back teeth.
