Today, several dental filling materials are available. Teeth can be filled with silver amalgam or tooth-colored,
plastic and glass materials called composite resin fillings. The location and extent of the decay, cost of filling material, patients' insurance
coverage and your dentist's recommendation assist in determining the type of filling that will best address your needs.
Advantages of tooth-colored composite fillings are:
1. Aesthetics - the shade/color of the composites can
be closely matched to the color of existing teeth; is particularly well
suited for use in front teeth or visible parts of teeth
2. Bonding to tooth structure - composite fillings
actually chemically bond to tooth structure, providing further support to the tooth
3. Versatility in uses - in addition to use as a
filling material for decay, composite fillings can also be used to repair
chipped, broken or worn teeth
4. Tooth-sparing preparation - sometimes less tooth
structure needs to be removed compared with amalgams when removing decay and
preparing for the filling
Bleaching (Tooth whitening)
Power or light-accelerated bleaching uses light energy which is intended to accelerate the process of bleaching.
The dentist will initially spread a peroxide based gel on the patient’s teeth. The gel will be left on the teeth for about 15 or 20 minutes.
Afterwards, the dentist will use a lamp to hasten the whitening course by stimulating minerals within the gel that is placed on the teeth.
People prefer this method because it’s relatively fast, it only needs to be done once, and there are very clear effects.
Use of light during bleaching increases the risk of tooth sensitivity and may not be any more effective
than bleaching without light when high concentrations of hydrogen peroxide are used.
