Bonding & White Fillings


Dental bonding is a technique that has been ussed for years.It can make the smile you’ve always wanted in just one visit.This treatment,if skillfully applied,is done by using the right amount and colour of dental composite.Depending on the type of bonding used,acrylic resins and a variety of filler are mixed into a paste with the composite.This bonding can be used for a variety of cosmetic dental procedures such as;

Filling dental cavities-‘white fillings’
Replacing the old amalgam or metal fillings
Repairing broken or chipped teeth
Closing gaps between teeth
Reshaping teeth
Make-over smiles using composite veneers,although porcelain veneers are a better choice.

Composite white fillings

Dental composite bonding is widely chosen for use in fillings as the colour can be matched to the natural tooth and it is not noticeable that you have fillings.Cosmetic dentists choose to change the old metal or amalgam as their has been debate over their mercury content.Sometimes dentists even take the extra precaution of using a rubber dam material when removing old fillings.

Can bonding be usaed for all cavities?

Composite bonding is suitable for big cavities as they are not strong enough over large areas.Bonding is more suited to small fillings that are not subject to great forces.Using the latest technology available,dentists are turning to the use of the CEREC systems ceramic fillings.These have the advantage of being stronger and can be fitted within an hour.Ceramic fillings have to be made by technicians which means a second visit to the dentist.

What is the procedure used with a composite bonding?

First a local anesthetic will be given if needed.Not all procedures need this.The tooth surface is thoroughly cleaned as the composite needs this to bond well.All tartar and debris is removed.The next stage is to establish the natural colour of your teeth and the composite is matched to that.The dentist will keep your tooth dry with cottonwool and will shape and roughen the surface of tooth with a special tooth.

The surface of the tooth is etched with a dental acid that will make the tooth perfect for the bonding agent of the composite.The composite is then bonded to the etched tooth and exposed to a special light which hardens and sets it in place.The bonding agent is applied in layers until the right shape is achieved.Once set the the tooth is polished and buffed to the correct shape and smoothness.

What are the disadvantages of composite bondings?

Its main disadvantage is that composite bondings are not as strong as ceramic or porcelain treatments.They can also stain more easily than porcelain or natural teeth.

Can all dentists offer bonding?

All dentists can offer this treatment but it is more skill based.Some dentists might not posess this.Cosmetic dentists will have undergone extra training in this field.Be sure to ask your dentist before you go through with this treatment to be sure you like the end result.
